Commercial solar that works
as hard as your business.
Engineered around your building's real load, then hand
Does commercial solar make sense in South Carolina?
It depends far more on when your building draws power than on how much roof it has. Under post-2021 export terms, production consumed on site is worth the full retail rate while exported production earns a few cents, so a building that peaks at midday converts solar very differently from one that peaks after dark. We read interval data rather than assuming a nine-to-five profile, and we confirm the serving utility before sizing anything.
The real problem
Energy is a rising line item, and a rooftop mistake is expensive
South Carolina utilities keep raising rates, and for a business, demand charges and daytime consumption make the power bill one of your least predictable fixed costs. Meanwhile a poorly engineered rooftop array can void a roof warranty, trip up an interconnection, or underperform for decades.
We approach it like engineers, not salespeople: we analyze your actual load profile and utility tariff, design for your specific roof or site, and stand behind the whole system, so solar becomes a predictable cost you control, not another vendor to chase.
We handle everything
From load analysis to monitored and switched-on, one accountable team

- 02
Permitting, interconnection & financing
We manage permits, the point-of-interconnection study with your utility (Dominion, Duke, Santee Cooper, or your co-op), and coordinate financing paths, you don’t chase paperwork.

Honest numbers

What drives the price
Your load profile and demand charges, roof or ground-mount site complexity, array size, and your utility’s tariff. We size to your operation, not our margin.

Commercial solar FAQ
What SC business owners ask us first
Is commercial solar worth it for a South Carolina business?
It depends on your consumption, demand charges, and utility rate, so we won’t promise a payback. We build a feasibility model from your actual load, then show you honest numbers. Businesses may also be able to use MACRS depreciation and South Carolina’s 25% state tax credit; confirm those with your tax professional.
What incentives can a business claim for solar in 2026?
In South Carolina, businesses may benefit from MACRS accelerated depreciation, the state’s 25% tax credit (up to $3,500/year, carried forward up to 10 years), and property- and sales-tax exemptions. Federal business-side provisions differ from the expired residential credit and can change, we’ll point you to what applies and recommend your CPA confirm eligibility.
What kinds of buildings and sites can you install on?
Flat and low-slope commercial roofs, ground-mount arrays, and solar carports, for offices, warehouses, retail, agriculture, and multifamily or HOA common areas. We engineer the mounting to your specific structure and back every roof penetration for life.
Will a rooftop array affect our roof warranty?
We install with a lifetime roof-penetration warranty, so if a penetration we made ever leaks, fixing it is on us for the life of the system. Where a roof is near end-of-life, we’ll tell you honestly and can coordinate roofing first.
How do you handle the utility interconnection and permitting?
We manage it, permits with your local authority and the interconnection application and study with your utility (Dominion, Duke, Santee Cooper, or your co-op). Which utility and terms apply depends on your exact service address, which we confirm during the assessment.
