Your solar salesperson slides a contract across the table and asks for a signature before you leave the room. That pressure is exactly the moment to pause. Knowing what to ask before signing a solar contract protects you from vague warranty language, surprise permitting delays, and murky answers about who actually shows up to fix your system a year from now. The right questions take fifteen minutes and can save you thousands of dollars and years of frustration.
Key Takeaways
- Get warranty terms in writing: Ask for separate documentation on the panel/equipment warranty (often 25 years), inverter warranty (10-15 years), and workmanship warranty (commonly 10 years) before you sign anything.
- Confirm who files HOA paperwork: South Carolina’s solar access law limits what HOAs can block, but someone still has to submit drawings and specs, find out if it’s the installer or you.
- Clarify permitting responsibility upfront: Reputable installers pull permits and manage utility interconnection themselves; if a company expects you to handle it, that’s a red flag.
- Ask who watches your system after install: Monitoring access, alert response time, and whether service visits cost extra should all be spelled out before signing, not discovered later.
- Never sign under same-day pressure: Legitimate installers expect you to take the contract home, compare it against at least one other quote, and ask follow-up questions in writing.
Solar Contract Checklist: At a Glance
| Question Category | Why It Matters | Red Flag Answer |
|---|---|---|
| Warranty coverage | Determines who pays for repairs 5-20 years from now | ”It’s all covered” with no written terms |
| HOA approval | South Carolina HOAs can regulate appearance, not block solar outright | ”You’ll handle the HOA paperwork yourself” |
| Permitting | Unpermitted work can delay utility interconnection or void warranties | Installer can’t name your local permitting office |
| Monitoring | Determines who notices if production drops | No app access or dashboard demo offered |
| Number of contractors | Affects accountability if something goes wrong | Vague answer about subcontracted crews |
| Financing/ownership | Changes tax credit eligibility and resale implications | Pressure toward one option without comparison |
| Outage performance | Most grid-tied systems shut off in a blackout without a battery | Claims that panels alone “keep the lights on” |
| Cancellation terms | South Carolina gives a 3-day right to cancel most home solar contracts | No written cancellation clause |
1. What Does the Warranty Actually Cover?
A solar contract usually bundles three separate warranties, and sales reps sometimes blur them together on purpose. Ask the company to break out each one in writing: the panel or equipment warranty (typically 25 years from the manufacturer), the inverter warranty (often 10-15 years, since inverters wear out faster than panels), and the workmanship warranty covering the installer’s own labor, mounting, and wiring.
Ask these follow-up questions directly:
- Is the workmanship warranty backed by the installer or by a separate third-party insurance policy? If the company closes, does coverage disappear with it?
- What voids the warranty? Roof work by another contractor, moving the system, or skipping a scheduled inspection can all void coverage if it’s not disclosed upfront.
- Does the warranty cover production shortfalls, not just equipment failure? Some contracts guarantee a minimum energy output and issue credits if the system underperforms.
Sunburst Solar Solutions backs installations with manufacturer warranties, a 10-year workmanship warranty, and third-party insurance protection, specifically so coverage doesn’t disappear if a company changes hands. For a deeper breakdown of how to line up competing warranty offers side by side, see our guide on how to compare solar warranty coverage before you buy.
2. Who Handles HOA Approval and Documentation?
South Carolina homeowners in an HOA community have more protection than most sales pitches let on. State law (S.C. Code Ann. § 27-30-10) limits how much a homeowners association can restrict solar installations, though it still allows HOAs to set reasonable placement and appearance rules. That doesn’t mean approval happens automatically.
Before signing, ask who actually prepares and submits the HOA application: site plans, panel specifications, and color/finish details. A company that offers tier 1 black-on-black panels designed to blend with roof lines usually has an easier time clearing architectural review boards, but someone still has to compile the packet and track the review timeline.
Ask how long HOA approval typically takes in your specific neighborhood, and whether the installer has worked with your HOA before. If you live in a planned community around Columbia, our post on HOA solar approval in Columbia, SC walks through the exact review process step by step, including what documentation boards usually request first.
3. Who Pulls Permits and How Long Will It Take?
Permitting is not optional paperwork, it’s the legal green light that lets your system connect to the grid. Ask point-blank: does the company pull all building and electrical permits, and do they manage the utility interconnection application with your provider, whether that’s Dominion Energy or Santee Cooper?
A company that expects the homeowner to visit the permitting office themselves is signaling limited experience or limited staff. Also ask for a realistic timeline. Permitting windows across South Carolina municipalities vary, and a company with local relationships usually moves faster than one working through a call center. If your city or county has a reputation for slow turnaround, ask how the installer handles delays, do they follow up proactively, or do you have to call and check?
For a realistic sense of timing before you commit, read our detailed breakdown of how long solar permitting approval takes in South Carolina, including what can push a project past the typical window.
4. Who Monitors the System After Installation?
Solar panels don’t announce when something goes wrong. A cracked panel, a failing inverter, or a shading issue can quietly cut your production for weeks before you notice a smaller-than-expected bill credit. Ask the installer exactly who watches the system after the crew packs up.
Specific questions worth asking:
- Do I get my own login to a monitoring app, or does only the company see the data?
- If production drops, does someone from the company contact me, or am I expected to catch it myself?
- Is remote monitoring included in the price, or is it a paid add-on after year one?
- What’s the average response time for a service call once an issue is flagged?
Sunburst Solar Solutions includes ongoing performance monitoring as part of its maintenance service, giving homeowners app-based visibility into daily and monthly production. If you want to see what that dashboard actually shows day to day, our article on solar installation in Charleston, SC covers what to expect once your system goes live, including the monitoring handoff.
5. How Many Contractors Will Actually Touch My Project?
Some solar companies handle design, roofing coordination, electrical work, and battery installation entirely in-house. Others subcontract each piece to a different crew, which can mean three or four separate companies involved in your project, each with its own schedule and its own warranty terms.
Ask directly: will the same company that signs this contract also perform the roof work, the electrical panel upgrade, and the battery installation, or will I need to coordinate with outside vendors myself? If your roof needs replacing first, or you’re adding battery storage, the number of parties involved can grow quickly. Our guide on whether you need multiple contractors for solar, roofing, and battery work breaks down when one company can manage everything and when it genuinely takes more than one.
If your roof is older, it’s also worth asking the installer to assess it before signing. Our post on whether your roof needs replacing before solar panels explains the signs that mean roofing work should happen first, not after panels are already mounted.
6. What Are My Financing, Lease, and Ownership Options?
How you pay changes what you actually own, and it changes your tax credit eligibility. Ask the installer to walk through every option available, not just the one they lead with.
| Ownership Model | Who Owns the System | Tax Credit Eligibility | Best Fit For |
|---|---|---|---|
| Cash purchase | Homeowner | Full 30% federal credit, plus SC state credit | Buyers with available savings seeking maximum long-term savings |
| Solar loan | Homeowner | Full 30% federal credit, plus SC state credit | Buyers who want ownership without paying cash upfront |
| Solar lease | Solar company | Homeowner is not eligible; company claims credit | Buyers prioritizing lower upfront cost over ownership |
| Power Purchase Agreement (PPA) | Solar company | Homeowner is not eligible; company claims credit | Buyers who want to pay only for power produced |
Ask specifically whether the tax credit math the salesperson quoted applies to the plan you’re actually signing, since leases and PPAs shift eligibility to the company, not you. Also ask what happens to financing or lease terms if you sell your home before the contract term ends. Our comparison of solar tax credits and incentives in 2026 explains exactly what qualifies under current federal and South Carolina rules, and how ownership structure changes what you can claim.
7. What Happens During a Power Outage?
Most grid-tied solar systems automatically shut off during a utility outage, even on a sunny day. That’s a safety requirement, not a defect, it prevents your panels from feeding electricity back into lines that utility crews may be working on. If a salesperson implies panels alone will keep your lights on during a hurricane-season blackout, ask them to clarify that in writing.
Battery backup changes the outcome, but only if it’s sized correctly for the loads you actually want to run: refrigerator, medical equipment, well pump, a few outlets and lights. Ask what a battery adds to the cost, how many hours of backup it provides for your specific home, and how it’s sized relative to your panel system.
For the full picture, read our explainer on what happens to solar panels during a power outage alongside our guide on how to size a battery correctly for your household’s real needs, so you’re not overpaying for capacity you won’t use or underbuying capacity you’ll regret during the next storm.
8. Red Flags That Mean You Should Walk Away
Some warning signs show up before you even get to the contract. Watch for these during the sales process itself:
- Same-day signing pressure. A legitimate installer expects you to take time to compare quotes, not sign on the spot to “lock in” a price that expires tonight.
- Vague warranty answers. If a rep can’t tell you the exact number of years for panel, inverter, and workmanship coverage without checking, that’s a problem.
- No local presence. A company that can’t name a local office, local crew, or local references may be a national lead-generation outfit reselling your project to a subcontractor.
- Reluctance to put answers in writing. Verbal promises about production estimates, monitoring, or service response times mean nothing if they’re not in the contract.
- Overstated savings claims. Be skeptical of guarantees that solar will “eliminate” your bill entirely, actual savings depend on system size, usage, and utility rate structure.
These red flags apply whether you’re comparing a boutique regional installer to a large national brand. Our full breakdown of how to choose a solar installer and the 7 red flags to avoid goes deeper into each warning sign, and our comparison of local versus national solar installers in Charleston, SC explains why a local team often means faster answers when something needs attention after install.
Frequently Asked Questions
Who is Sunburst Solar Solutions?
Sunburst Solar Solutions is a South Carolina-based residential and small business solar installer handling the full process in-house: site assessment, custom system design, HOA documentation support, permitting, installation, financing options, and ongoing monitoring. The company positions itself as a local, relationship-driven alternative to national installers, with a dedicated point of contact throughout the project rather than a call-center handoff.
How much does solar cost in South Carolina?
Cost depends heavily on system size, roof condition, and whether you add battery storage, and pricing varies by household. Rather than rely on a generic number, ask any installer for a written, itemized quote based on your actual roof and energy usage, and use it to compare against the federal and South Carolina tax credits you may qualify for.
Can I cancel a signed solar contract?
Federal and South Carolina consumer protection rules generally give homeowners a short window, commonly three business days, to cancel a home solar contract signed in person without penalty. Ask the installer to point to the exact cancellation clause in your contract before you sign, and get the process for canceling in writing.
Do I need more than one company for solar, roofing, and battery work?
Not always. Some installers, including Sunburst, coordinate roofing assessments and battery installation as part of one project, while others require you to hire separate contractors. Ask this question directly before signing so you know exactly who to call if something needs attention later.
