Commercial solar financing in South Carolina is an ownership and risk decision before it is a payment decision. Keep one technical project and cash price constant. Then compare who owns the equipment, when money moves, what secures repayment, who receives energy and tax attributes, and what happens during delays, roof work, property transfer, default, buyout, and the end of the agreement.
Cash, conventional or equipment debt, and a regulated solar equipment lease can produce very different obligations. National comparison charts often add a power purchase agreement and C-PACE as if both are available in every state. That is not a safe assumption in South Carolina. The state-specific legal and program checks belong near the start of the analysis, not after a term sheet is signed.
This guide is a decision framework, not a loan offer or tax, legal, or accounting opinion. Sunburst does not advertise a lender, rate, approval, tax result, PPA product, or C-PACE closing through this article. The useful outcome is a written finance comparison your management team and independent advisers can verify.
Map the five ownership roles before comparing payments
A commercial property can involve several legal entities. The building owner may lease space to an operating company. A parent may own both through subsidiaries. The electric account may be in a tenant’s name. A lender may have a mortgage on the real estate. A separate solar owner may hold title to the equipment.
Write down the legal name and role of each party:
- Facility owner: owns the land, building, roof, parking canopy, or ground area.
- Solar-system owner: holds title to the modules, inverters, racking, and related equipment.
- Utility customer: signs the interconnection/rate documents and receives the electric bill.
- Operating beneficiary: uses the building and expects lower purchased-energy expense or another project benefit.
- Borrower, lessee, or payment obligor: owes the finance payments and grants any collateral or contract rights.
Those roles can belong to one entity, but never assume they do. A financing structure can fail even when the solar design works if the borrower lacks roof rights, the utility customer will not sign, a mortgage lender must consent, or the entity expected to use a tax attribute does not own the required property.
Build an ownership-and-benefit schedule:
| Item | Named owner or recipient | Document that controls |
|---|---|---|
| Building, roof, carport, or ground area | Deed, property lease, easement, roof license | |
| Solar equipment | Purchase agreement, bill of sale, lease, financing documents | |
| Electricity used on site | Utility tariff, interconnection agreement, property/tenant agreement | |
| Export credit or utility payment | Utility account and applicable tariff/program | |
| Renewable energy certificates or environmental claims | Installation, finance, lease, or separate REC agreement | |
| Federal credit and depreciation | Tax ownership, credit rules, elections, tax filings | |
| South Carolina income-tax credit | Facility and system ownership, state law, tax return | |
| Rebates or program payments | Current utility/program approval and assignment terms | |
| Equipment and workmanship warranties | Manufacturer, installer, EPC, lease, and O&M agreements | |
| Monitoring and production data | Platform account, privacy/data terms, O&M agreement | |
| Insurance and casualty proceeds | Property, equipment, liability, lender, and contract terms | |
| Residual value and removal duty | Purchase, lease, buyout, and end-of-term language |
Do not use “the business” in a proposal when several affiliates are involved. Taxpayer, property owner, borrower, system owner, and utility customer are legal roles, not marketing shorthand.
Fix one project scope and cash price first
Financing offers cannot be compared when the underlying projects differ. One quote may include roof work, switchgear, interconnection studies, monitoring, and construction contingencies. Another may finance only the panels and inverters. A lower payment can come from missing scope rather than better capital.
Start with the complete installed cash price before incentives and financing. The commercial solar cost guide explains how to separate the solar-only price from roof, battery, major electrical, civil, financing, and other work. Use that same design, equipment, assumptions, schedule, and responsibility map for every funding scenario.
Record at least:
- cash contract price and every allowance, alternate, and exclusion;
- engineering, permitting, interconnection, construction, commissioning, and closeout scope;
- site, roof, structural, electrical, civil, and utility dependencies;
- expected contract execution, design, approval, construction, completion, interconnection, and placed-in-service milestones;
- equipment substitutions and change-order rules;
- production model, utility tariff, self-consumption, export, demand, maintenance, and degradation inputs;
- property ownership and occupancy horizon;
- tax assumptions supplied by the business’s adviser, not the salesperson; and
- the party responsible when a condition or deadline is missed.
Then add each funding structure as a separate cash-flow and contract layer. Keep financing fees and interest out of the solar cash-price numerator. Keep an incentive out of the net price until the responsible adviser and program have verified eligibility, timing, amount, and recipient.
This separation also protects the management decision. The board can approve the project because its unfinanced economics and operational fit are acceptable, then approve a funding method because its capital cost and risks fit the organization. A low monthly payment should not rescue a project whose technical or tariff assumptions do not work.
Cash purchase: simple funding, not a simple decision
With an internal cash purchase, the purchasing entity generally funds the EPC or installation contract from cash reserves and receives title under the signed documents. There is no third-party financing payment, but the project still has opportunity cost, construction-payment timing, property rights, tax, insurance, warranty, and performance risk.
Cash can be appropriate when the organization:
- has available capital after preserving operating liquidity and required reserves;
- wants direct asset ownership and control;
- is prepared to manage operations, maintenance, warranty, and replacement duties;
- can obtain every property, lender, utility, and governance approval;
- has advisers who can evaluate its actual tax position; and
- prefers to avoid a long lender, lessor, or energy-purchase contract.
Ask what the same capital would otherwise fund. A solar project competes with inventory, equipment, expansion, debt reduction, acquisitions, reserves, and distributions. The relevant hurdle rate and liquidity policy belong to the business, not the installer.
Cash also does not mean paying the entire contract at signature. Normalize the construction payment schedule:
- deposit or mobilization payment;
- design or engineering milestone;
- equipment procurement or delivery;
- permit and interconnection approval;
- start or progress of construction;
- mechanical or substantial completion;
- inspection and utility authorization;
- commissioning, monitoring, training, and final documents; and
- retainage or unresolved punch-list treatment.
The contract should connect each payment to objective evidence. Decide who bears stored-material risk, supplier deposits, price changes, substitution, damage, theft, insolvency, delays, and cancellation before releasing large progress payments. Obtain legal advice on lien waivers, title passage, warranties, and remedies appropriate to the project.
Cash does not guarantee the best return, tax result, or fastest payback. Those outcomes depend on the same project cash flows and alternative capital uses evaluated in the commercial solar ROI guide. Cash simply removes a finance provider from the capital stack.
Conventional and equipment debt: compare the complete credit agreement
Under a conventional commercial loan or qualifying equipment-finance structure, the purchasing entity normally owns the solar equipment subject to the signed security and loan documents. Ownership can preserve control and potential owner tax attributes, but debt adds financing cost, repayment risk, covenants, collateral, and another approval schedule.
The Department of Energy’s commercial loan overview says the customer generally arranges financing, purchases and owns the equipment, and manages the project. DOE also notes that availability and terms can depend on creditworthiness, existing debt, project facts, and collateral. Those are market principles, not an offer to a South Carolina business.
Ask what is being financed
The committed amount may cover:
- the EPC or installation contract;
- engineering, permits, studies, interconnection, and utility work;
- roof, electrical, structural, civil, or resilience scope;
- lender, legal, appraisal, filing, inspection, or closing costs;
- eligible contingency or change orders;
- construction-period interest;
- taxes and insurance; or
- a bridge against an expected credit or other later source.
Never infer inclusion from the approved loan amount. Match every project cost to equity, loan proceeds, another funding source, or an unresolved gap. If a tax-credit bridge or expected rebate is part of the capital stack, define the repayment date and backup source if the tax/program benefit is smaller, later, challenged, or unavailable.
Normalize rate and payment terms without assuming a rate
Collect the actual term sheet and draft documents for:
- fixed or variable rate and the index, margin, floor, ceiling, reset, and notice provisions;
- all origination, documentation, appraisal, legal, inspection, servicing, unused-commitment, late, default, and exit fees;
- borrower equity and when it must be funded;
- commitment period, draw conditions, draw frequency, inspection, invoices, lien waivers, and retainage;
- when interest begins and whether it is capitalized or paid during construction;
- amortization, maturity, balloon or residual amount, and complete payment schedule;
- prepayment rights, premium, lockout, yield protection, and payoff process;
- collateral, lien priority, UCC filings, deposit-account control, mortgage or leasehold interest;
- personal, parent, affiliate, or completion guaranties;
- debt-service, liquidity, leverage, insurance, reporting, and other covenants;
- restrictions on additional debt, distributions, asset sale, relocation, equipment changes, or change of control;
- events of default, cure periods, default rate, acceleration, repossession, and cross-default; and
- assignment, lender/servicer change, notice, dispute, and governing-law terms.
The best comparison is not interest rate alone. Calculate required cash at each milestone and the total scheduled debt service under the written assumptions, then stress variable rates, delayed completion, lower tax proceeds, change orders, and early payoff. A financing offer with a lower stated rate can cost more if fees, delayed draws, a balloon, collateral requirements, or prepayment terms differ.
SBA-backed financing is a possible lender path, not an entitlement
Some eligible small businesses may discuss SBA-guaranteed financing with participating lenders. The SBA 7(a) program can support eligible machinery/equipment installation and real-property uses, subject to borrower, lender, program, use-of-proceeds, credit, and repayment requirements. The SBA 504 program supports qualifying major fixed assets through Certified Development Companies working with senior lenders.
That does not mean SBA directly offers an ordinary solar loan or that a solar project, business, property structure, or use automatically qualifies. Apply through the proper lender or Certified Development Company and require written confirmation of eligible costs, structure, collateral, equity, term, prepayment, closing conditions, and project milestones.
SBA’s Lender Match guidance explicitly says a match is not an approval or offer. It tells borrowers to compare rates, fees, collateral, prepayment terms, grace periods, and circumstances under which full repayment can be demanded. Apply that discipline to conventional financing too.
A South Carolina solar lease is an equipment-use contract
A third-party solar lease separates use from ownership. The lessor owns the renewable generation facility, and the customer-generator lessee pays to use it under the lease. That changes tax ownership, maintenance control, insurance, roof work, transfer, default, buyout, and end-of-term decisions.
South Carolina has a specific statutory framework. S.C. Code §58-27-2610 and related provisions permit qualifying renewable-generation equipment leases under stated conditions. A nonutility lessor must hold a current certificate from the Office of Regulatory Staff before marketing or leasing covered facilities. Verify the exact legal entity through the ORS solar leasing information, not merely a salesperson, brand, parent company, or old certificate list.
The contract should identify:
- lessor, system owner, installer/EPC, operator, servicer, payment recipient, and any tax investor;
- ORS certificate number and exact entity name;
- equipment, site, roof rights, access, utility account, and interconnection responsibility;
- upfront, recurring, escalation, late, service, roof-work, transfer, buyout, extension, removal, and other payments;
- payment start and treatment of design, construction, delayed interconnection, outage, underproduction, or casualty;
- who receives electricity, exports, RECs, program payments, federal tax attributes, depreciation, and insurance proceeds;
- maintenance standard, response obligation, exclusions, labor, monitoring, network, replacement, and parts availability;
- warranties and who can submit, control, and receive a claim;
- restrictions on building, roof, electrical, tenant, or property changes;
- property sale, business sale, assignment, assumption, credit review, buyout, and consent process;
- casualty, condemnation, default, cure, early termination, removal, restoration, and bankruptcy terms; and
- scheduled end-of-term options and the price or valuation method for each.
Do not accept “maintenance included” without a service schedule and remedies. It may not include monitoring communications, truck rolls, damage outside warranty, vegetation, cleaning, roof removal/reinstallation, utility changes, storm damage, business interruption, or replacement after a manufacturer claim.
Do not accept “transferable” without the process. Transfer may require notice, application, purchaser/assignee approval, financial qualification, documents, fees, lender/lessor consent, utility action, and a closing timeline. Automatic transfer, free buyout, or free removal exists only if the documents create it.
Do not treat an onsite PPA as a generic South Carolina option
“PPA” can describe different transactions:
- an onsite host PPA, where a third-party owner sells the facility’s output to the business at the site;
- a utility offtake PPA, where a generator sells electricity to an electric utility under a utility/regulatory process; or
- an offsite or financial PPA, a larger corporate energy-procurement or hedging transaction that may not deliver rooftop electricity to the facility.
DOE’s commercial PPA overview describes an onsite host PPA as third-party-owned generation whose output is purchased by the customer. DOE also warns that this structure is available only where state and jurisdiction rules permit third-party ownership and electricity sales.
South Carolina’s lease law requires a more careful distinction. Section 58-27-2610 permits a certified equipment lease and says the statute does not allow the facility owner to sell electricity directly to the customer-generator lessee. It also treats the output of a leased facility as the lessee’s property. Meanwhile, ORS uses PPA terminology in a separate utility-offtake context for generators selling under utility processes.
That statutory text is why a national “lease or PPA” checkbox is not enough. Do not assume a proposed onsite host PPA is lawful, available, or equivalent to a certified equipment lease. Ask South Carolina energy counsel and the relevant regulatory/utility parties to identify:
- the exact transaction and electricity seller/buyer;
- the legal authority for a nonutility sale, if one is proposed;
- whether the agreement is actually an equipment lease, service contract, utility offtake, or financial hedge;
- required ORS certificate, PSC/utility process, tariff, interconnection, and reporting;
- electricity, export, REC, tax, operating, and meter ownership; and
- remedies if the proposed structure cannot receive approval.
This article does not say every transaction called a PPA is prohibited. It says the label is legally incomplete. A proposal should not promise an onsite PPA product, rate, savings, or approval without a written project-specific legal and regulatory basis.
C-PACE is not a verified current South Carolina option
Commercial property assessed clean energy, or C-PACE, appears in many national financing comparisons. DOE explains that C-PACE requires state enabling law and an active local program. In a functioning program, financing is repaid through a property-linked assessment under program-specific rules.
That generic definition does not establish availability in South Carolina. As of August 10, 2026:
- the General Assembly’s official S.256 status showed the proposed enabling bill remained in the Senate after failing second reading on January 20, 2026; and
- the official H.3812 status showed the companion remained in the House after committee referral.
No enacted statewide enabling law and active local South Carolina program were verified in this research. Therefore, do not include C-PACE proceeds, terms, or a C-PACE closing in the financing base case. A pending bill is not a funding source.
If the law changes later, require evidence of every layer before treating C-PACE as available:
- enacted statute and effective date;
- participating local jurisdiction and adopted program;
- administrator and current program guidebook;
- eligible property, owner, improvement, costs, and completion status;
- capital provider and binding financing terms;
- existing mortgage-holder consent;
- assessment, lien priority, billing, delinquency, enforcement, and payoff terms;
- engineering, savings, useful-life, code, permit, and interconnection requirements; and
- closing documents and independent legal, tax, accounting, mortgage, and title review.
Do not substitute a lender’s general C-PACE marketing page or experience in another state for those documents.

Match federal tax attributes to the actual owner and timeline
Federal business clean-energy rules changed recently and are not the former homeowner credit. The IRS Clean Electricity Investment Credit page describes Section 48E for qualifying clean-electricity investments placed in service after 2024. It has a base rate, a higher alternative rate when applicable requirements are met, possible bonus rules, ownership and qualified-basis requirements, and credit coordination.
“Commercial means 30%” is not a valid tax conclusion. The business’s tax adviser should document:
- exact taxpayer and direct system/facility ownership;
- tax classification and related entities;
- qualified facility, energy property, and eligible basis;
- contracts, invoices, allocations, rebates, grants, and excluded costs;
- construction-start evidence and continuity;
- placed-in-service date and operational evidence;
- prevailing-wage and apprenticeship applicability and records;
- domestic-content, energy-community, or other bonus assumptions;
- prohibited-foreign-entity/material-assistance rules where applicable;
- credit versus production-credit election and coordination;
- transfer or elective-pay eligibility, registration, election, documentation, buyer, price, and timing;
- tax-liability, passive-activity, general-business-credit, carryback/carryforward, and other limitations;
- basis adjustment and depreciation interaction; and
- recapture exposure after disposition, ownership change, casualty, or cessation of qualification.
Timing is now a finance risk. IRS Notice 2025-42 implements the 2025 statutory termination rule for applicable wind and solar facilities. If an applicable solar facility began construction after July 4, 2026, placed-in-service timing after December 31, 2027 can terminate the credit under that rule. The notice also addresses how construction beginning is established; a proposal signature, deposit, equipment order, site work, mechanical completion, utility approval, and placed-in-service date are not interchangeable.
The lender, EPC schedule, and tax schedule must therefore reconcile. State who owns deadline documentation, what evidence is required, what happens after a delay, and whether financing remains affordable without the assumed credit.
Transferability and elective pay are processes, not cash at closing
The IRS says Section 48E can be eligible for transfer, and certain applicable entities may use elective pay. Current IRS elective-pay and transfer guidance requires the correct entity, underlying credit qualification, prefiling registration, election, and tax-return process.
A transferable credit does not guarantee a buyer, price, closing date, net proceeds, insurance, indemnity, or freedom from recapture disputes. Elective pay does not mean every nonprofit or public entity receives an automatic refund. Model timing and transaction costs from the adviser-negotiated documents, with a fallback funding source.
Depreciation belongs to the tax owner
IRS Publication 946 explains that depreciating business/income-producing property requires the proper owner, basis, placed-in-service date, business use, class, method, convention, and elections. The current publication identifies qualifying Section 48E property as five-year property and explains current special-depreciation rules. That is not a deduction calculation for a particular business.
Ask the CPA to reconcile:
- legal and tax ownership;
- cost allocation and eligible depreciable basis;
- federal credit basis adjustment;
- state basis treatment;
- bonus-depreciation and other elections;
- taxable income and limitation effects;
- book-versus-tax differences; and
- disposition, buyout, or transfer consequences.
Under third-party ownership, the host should not count the owner’s credit or depreciation as its own. If the owner says some tax value is reflected in lease pricing, require the actual contractual payment schedule and compare it without calling the owner’s tax benefit a customer credit.
Treat the South Carolina credit as a taxpayer schedule, not a discount
South Carolina’s credit has ownership and usage limits that matter to commercial financing. The current Department of Revenue ruling interprets Section 12-6-3587 for qualifying purchase and installation on a South Carolina facility owned by the taxpayer.
DOR currently states:
- the calculated credit equals 25% of qualifying purchase and installation costs;
- use in a year is limited to the lesser of $3,500 per facility or 50% of the taxpayer’s South Carolina income-tax liability;
- the credit is nonrefundable and unused amounts can carry forward up to ten years;
- financing a purchase does not itself prevent a claim, but interest, insurance, origination fees, and extended warranties are not qualifying purchase/installation costs;
- a solar lessee does not qualify, and the lessor generally does not qualify because it does not own the host facility;
- the current state credit is not transferable; and
- an already-earned carryforward does not transfer with the facility/system when the property is sold.
Those are general DOR positions, not a promise that a specific business, affiliate, facility, system, cost, or transaction qualifies. The facility-owning taxpayer, system purchaser, tax-liability schedule, other credits, eligible costs, completion year, and carryforward capacity must be reviewed.
Do not subtract the full calculated state credit from the project price or loan at closing. A large commercial project can generate a calculated amount far above what the taxpayer can use in one year. The tax adviser should create an entity-specific schedule showing expected use, remaining carryforward, expiration risk, and treatment after a property or business transaction.
Entity selection deserves special care. If a real-estate LLC owns the facility while an operating company purchases or uses the system, the DOR ownership conditions may not line up with the economic beneficiary. Do not move contracts or invoices between affiliates after the fact to repair an assumption. Set the intended ownership and tax structure before signing, then let counsel and the CPA confirm it.
Align the finance term with the roof, property, and business horizon
A technically durable array can outlast a roof plan, commercial lease, tenant, mortgage, or owner’s hold period. Put every horizon on one page:
- remaining roof service life and roof warranty;
- solar equipment and workmanship coverage;
- finance or equipment-lease term;
- building ground lease, space lease, roof license, or easement term;
- utility/interconnection agreement and tariff eligibility;
- expected property hold and business occupancy;
- major facility renovation, expansion, HVAC, electrical, or roof plans;
- insurer renewal and catastrophe exposure; and
- end-of-term removal, extension, purchase, and restoration dates.
If the business leases its facility, the operating lease must grant sufficient rights for design, construction, operation, utility access, lender/lessor entry, maintenance, roof work, removal, and restoration. It should allocate electricity, rent, common-area charges, taxes, insurance, improvements, and end-of-lease duties. A long solar contract cannot rely on a short or revocable roof consent.
If the property owner and operating company are affiliates, document the rights anyway. A future sale, refinancing, bankruptcy, new investor, or separation can expose an informal arrangement.
Roof work needs a finance clause, not just a construction plan. Identify:
- who decides removal is necessary;
- authorized detach/reinstall provider;
- notice and scheduling;
- labor, equipment, storage, damage, and lost-production cost;
- continuing finance or lease payments during downtime;
- warranty and insurance allocation;
- design changes or unavailable parts; and
- restoration and recommissioning acceptance.
The Sunburst warranty guide helps separate manufacturer, performance, workmanship, roof, and service obligations. A finance provider’s lien or ownership does not replace those warranties, and a warranty does not pay a loan unless the contract says it does.
Reconcile payment timing with project and utility milestones
Commercial solar can have four separate clocks:
- Construction contract: deposit, design, procurement, construction, substantial completion, final completion.
- Financing: commitment, conditions precedent, equity funding, draws, interest start, amortization, maturity.
- Utility and government: permits, studies, interconnection approval, inspections, permission to operate, program reservation/payment.
- Tax: construction start, completion, placed in service, tax filing, credit transfer/elective-pay registration, depreciation.
A financing plan fails when one clock assumes another has finished. Require a milestone table:
| Milestone | Evidence | Cash due or available | Responsible party | Delay consequence |
|---|---|---|---|---|
| Contract and financing approval | Signed documents and conditions list | Equity/deposit | ||
| Design/site diligence | Approved engineering/site deliverables | Design draw | ||
| Equipment procurement | Supplier documents, title/risk terms | Procurement draw | ||
| Permit/interconnection approval | Written AHJ/utility approval | Construction authorization | ||
| Construction progress | Inspection, invoices, waivers | Progress draw | ||
| Substantial completion | Defined completion certificate | Milestone payment | ||
| Inspection and energization | Final inspection and utility authorization | Conversion/final draw | ||
| Commissioning/closeout | Tests, monitoring, training, as-builts, warranties | Retainage/final payment | ||
| Tax/program milestone | Adviser/program evidence | Credit, transfer, elective pay, or rebate if realized |
Never make an unavoidable debt payment depend solely on a projected utility saving or tax receipt. The obligation may begin before the system operates, and the actual benefit may differ. Model a funding reserve or alternate payment source and assign responsibility for delay, redesign, study cost, interconnection upgrade, failed inspection, force majeure, and provider default.
Utility approval remains separate from financing. Dominion Energy South Carolina’s current Solar for Your Business page says Dominion does not finance installations or give tax-credit advice and requires its own application/approval path. Santee Cooper’s current 2026 Solar Business Program Manual has separate account, equipment, contractor, application, approval, inspection, period, and funding conditions.
Do not infer a provider or program from a city. Verify the utility on the bill and use the South Carolina utility directory to find current primary documents. A lender approval is not interconnection approval. Utility approval is not finance approval. Neither is tax eligibility.

Negotiate transfer, default, buyout, and provider-failure terms
Financing is easiest to discuss when the project succeeds and every party remains unchanged. Review it instead from the difficult events.
Property or business sale
Ask whether the obligation is paid off, assumed, assigned, or left with the seller. Identify required notice, financial qualification, consent, fees, documents, lien releases/subordination, utility transfer, equipment title, warranties, data, and closing timing. A property buyer should not discover a solar approval process after the purchase agreement is signed.
Refinancing or new debt
The mortgage lender and solar financier may dispute collateral, fixture status, lien priority, access, casualty proceeds, or removal rights. Obtain consent, intercreditor, subordination, nondisturbance, or other required documents before installation. Do not promise that a UCC filing is “not a lien on the building” without counsel reviewing the actual filing and property law.
Change of control or tenant change
A stock sale, asset sale, merger, ownership change, assignment, sublease, or new utility account can trigger consent or default even when the property is not sold. Map change-of-control definitions across the loan, lease, property, utility, and installation contracts.
Default and cure
Identify payment and nonpayment defaults, notice, cure, acceleration, repossession, equipment shutdown, site access, removal, restoration, damages, cross-default, and lender remedies. If the solar system is operationally important, ask whether a dispute could interrupt monitoring, service, or use and what step-in rights exist.
Casualty, condemnation, and insurance
Name the insured property, additional insureds, loss payees, deductibles, exclusions, claim control, repair standard, finance-payment treatment, and allocation of insurance proceeds. Decide whether a partial loss leads to repair, replacement, prepayment, or termination. Business-interruption coverage and solar production obligations are separate questions.
Buyout and end of term
Do not translate “purchase option” into a free or nominal transfer. The contract may use a fixed schedule, formula, fair-market-value process, appraisal, tax-driven timing, or no early option. Define taxes, fees, removal, restoration, equipment condition, title, liens, warranties, spare parts, data, and interconnection transfer after purchase.
Provider assignment or failure
Finance and lease contracts may permit assignment to another owner, lender, servicer, or investor. Ask what notice and consent rights exist and whether service obligations move with payment rights. If the installer, lessor, tax investor, platform, or servicer fails, identify who still owns equipment, receives payment, controls warranties, maintains insurance, operates monitoring, and can authorize roof work or removal.
Give each adviser a defined review assignment
“Reviewed by advisers” is too vague. Assign questions and require written exceptions.
| Reviewer | Questions to own |
|---|---|
| Management / board | Strategic fit, liquidity, hurdle rate, authority, risk tolerance, property hold, future operations |
| CFO / treasury | Capital budget, payment schedule, total obligation, cash reserve, covenants, debt capacity, downside funding |
| CPA / tax adviser | Tax owner, entity, basis, credit, depreciation, elections, transfer/elective pay, state limits, filing, recapture |
| Accountant / auditor | Current GAAP treatment, lease/PPA analysis, asset/liability recognition, disclosures, controls, book-tax differences |
| South Carolina counsel | Entity authority, property/roof rights, lease/PPA legality, contracts, collateral, remedies, transfer, default |
| Property lender / title | Mortgage consent, lien priority, fixture treatment, access, insurance proceeds, sale/refinance requirements |
| Insurer / risk adviser | Property, liability, construction, equipment, wind/flood, business interruption, loss payee, claim allocation |
| Facility / roof team | Roof life, access, shutdown, operations, maintenance, detach/reinstall, acceptance |
| Utility / energy adviser | Correct account, tariff, interval load, interconnection, program, export, demand, account transfer |
| Installer / engineer | Fixed technical scope, schedule, production model, permits, studies, construction, commissioning, closeout |
DOE’s Financing Navigator fit tool says there are no cut-and-dried rules for balance-sheet treatment and the accounting team makes the final determination. Do not let a solar proposal label a lease or PPA “off balance sheet,” “fully deductible,” or an operating expense as a guaranteed accounting outcome.
The same caution applies to legal and tax labels. A contract name does not establish substance. A “lease” can contain purchase, control, residual, and service terms that advisers must analyze. A “PPA” may not be an available onsite sale. “SBA eligible” does not mean approved. “Transferable credit” does not mean cash received. “C-PACE ready” does not mean South Carolina has an enacted, active program.

For each row, mark included, excluded, allowance, conditional, not applicable, or unresolved. State who owns the item and where the term appears. If a salesperson’s summary conflicts with the draft agreement, the agreement needs correction before signature; a slide deck should not control a multimember capital stack.
Then run downside cases in the commercial ROI model. This financing comparison defines the funding inputs; return analysis should test them rather than choosing a structure from a monthly payment.
When to request a commercial assessment
Request a commercial assessment after the decision team identifies the facility, utility accounts, ownership entities, roof/property horizon, and funding goals—but before it selects a finance label or commits to equipment. The assessment should establish a buildable project and cash-price baseline that lenders, lessors, tax advisers, and management can evaluate consistently.
Sunburst’s commercial solar service confirms a path for load/tariff review, design, permitting, interconnection, construction, commissioning, monitoring, and coordination of financing paths. The commercial service-area hub can help locate the applicable local page. Those pages do not promise a lender, approval, rate, lease/PPA provider, C-PACE availability, tax result, or accounting treatment.
If your team wants one scope and cash-price baseline before comparing funding structures, request a free commercial solar assessment. Bring bills and interval data, ownership/entity information, property or roof lease, existing debt/consent constraints, roof plans, financial objectives, and adviser questions. The goal is a decision package—not a preselected payment product.
Sunburst keeps the construction scope stable while your advisers compare funding. We provide the fixed cash price, the milestone schedule tied to real project and utility events, the equipment list and the warranty exhibits, so a lender, lessor or CPA is evaluating the same asset in every scenario. We do not present tax outcomes as savings guarantees, and we will not restructure the scope to make a payment look smaller.
Our commercial solar service covers design, permitting, interconnection, construction and closeout statewide from Daniel Island — see the local scope in Columbia or Beaufort — and financing and incentives explains the South Carolina credit mechanics we work within. If the building is leased rather than owned, read the site-control guide before financing conversations begin; if the returns are still unproven, start with the ROI audit.

Commercial solar financing FAQ
What is the best way to finance commercial solar in South Carolina?
There is no universal best structure. Compare the same project under internal cash, owner debt/equipment financing, and any legally available third-party structure. Evaluate total obligation, liquidity, tax ownership, collateral, covenants, payment timing, property horizon, transfer, default, and end-of-term terms. The answer depends on the business’s capital policy and verified contracts, not the smallest opening payment.
Does a commercial solar loan let the business claim tax benefits?
Financing a purchase can preserve ownership, but ownership alone does not establish eligibility. The exact taxpayer, facility, system, basis, construction and placed-in-service timing, labor/bonus rules, tax liability, elections, and other limits matter. The lender does not decide the tax result. Have the business’s tax adviser confirm it using current federal and South Carolina guidance.
Can an SBA loan pay for a commercial solar system?
An eligible small business may discuss applicable 7(a) or 504 fixed-asset uses with a participating lender or Certified Development Company. SBA does not guarantee that a particular business, solar project, cost, or structure qualifies, and an introduction is not approval. Require written use-of-proceeds, collateral, equity, term, fee, draw, and closing analysis from the authorized lender.
Is C-PACE financing available in South Carolina?
It was not verified as an active option on August 10, 2026. The current Senate enabling bill had failed second reading, and its House companion remained in committee. DOE says C-PACE requires enacted state authority and an active local program. Do not budget C-PACE funds unless later primary documents prove current statute, jurisdiction, program, administrator, guidebook, lender, mortgage consent, and closing terms.
Can a South Carolina business sign a solar PPA?
Do not answer from a national chart. South Carolina permits certified solar equipment leases, while its lease statute says it does not authorize the equipment owner to sell electricity directly to the host lessee. Utility offtake and offsite/financial PPAs are different transactions. Ask South Carolina energy counsel and the relevant utility/regulator to confirm the exact proposed structure before treating an onsite host PPA as available.
Who gets the federal credit and depreciation under a solar lease?
The third-party system/tax owner generally evaluates owner tax attributes; the host should not record them as its own. The actual owner, qualified basis, placed-in-service facts, elections, current law, and tax filings control. If an owner says tax value lowers lease payments, compare the contractual payment schedule. Do not call the owner’s tax attribute a customer credit.
Can a commercial tenant finance solar on a leased building?
Potentially, but the tenant needs sufficient property/roof rights and all required owner, lender, utility, insurer, and governing approvals. Align the solar/finance term with the property lease and allocate electricity, improvements, access, roof work, default, removal, restoration, and lease-end duties. The South Carolina state tax credit also has facility-ownership conditions requiring adviser review.
Should the financing term match the solar warranty?
Compare them, but do not assume they cover the same risk. Finance payments, equipment warranties, performance warranties, installer workmanship, roof coverage, O&M, insurance, and utility approval are separate obligations. A long manufacturer warranty does not promise labor, uptime, cash flow, or debt payment. Resolve gaps in the contracts and reserves.
What should a commercial solar financing term sheet disclose?
It should identify the exact project/cash price, parties, ownership, funded uses, equity, draws, payment schedule, rate and fees, collateral, covenants, guaranties, prepayment, tax assumptions, utility/program assumptions, transfer, change of control, default, casualty, buyout, removal, service, assignment, accounting treatment, and unresolved conditions. Each claim should point to a controlling document.
