FAQs
How does Charleston’s climate affect solar panel performance?
Charleston enjoys about 215 sunny days per year, which is ideal for photovoltaic (PV) production. Modern panels are tested to operate efficiently in temperatures up to 185 °F, so summer heat only slightly reduces output. In winter, cooler temperatures actually improve efficiency. Our design team models your exact roof orientation and local weather data to ensure your array is sized for maximum annual production.
What incentives and tax credits are available for solar installation in Charleston?
Homeowners can claim the 30 % federal Investment Tax Credit (ITC) through 2032. South Carolinians can also receive a state income-tax credit worth 25 % of the system cost, capped at $3,500 per year or 50 % of their tax liability, whichever is smaller. Additionally, Dominion Energy and Berkeley Electric offer net-metering programs that credit excess power sent back to the grid, further improving your return on investment.
How long does the installation process typically take?
From signed contract to power-on, most residential projects finish in 6–10 weeks. This timeline includes site assessment (1 week), engineering and permitting (2–4 weeks, dependent on local AHJ backlogs), physical installation (1–3 days), utility inspection (1 week), and interconnection approval (1–2 weeks). We coordinate every step and provide real-time updates via our customer portal.
What warranties and maintenance services do you offer to ensure reliable performance?
All panels come with a 25-year manufacturer performance warranty guaranteeing at least 92 % output in year 25. Inverters carry 12–25-year warranties depending on model. Our workmanship warranty covers roof penetrations, wiring, and racking for 10 years. We include a complimentary performance check at year 1, and optional annual maintenance plans cover cleaning, monitoring alerts, and on-site inspections to keep your system running optimally.
Can solar panels withstand hurricanes and coastal storms common in South Carolina?
Yes. We use wind-rated racking systems certified to meet or exceed Charleston County’s 140 mph design wind speed requirements. Panels are tested to UL 61730 standards for impact and uplift. During installation, we anchor racking into roof rafters or concrete with sealed flashing to prevent leaks. In the rare event of hurricane damage, your homeowner’s insurance typically covers repairs, and our rapid-response team is available for post-storm inspections.
How much can I expect to save on my electric bill, and what financing options are available?
Savings depend on roof size, shading, and current utility rates. A typical 8 kW system in Charleston produces about 11,000 kWh annually, offsetting roughly $1,600 in electricity costs at today’s rates. With federal and state tax credits, most customers achieve a 7–9 year payback and 15–17 % internal rate of return. We offer $0-down solar loans (5–25 years), cash discounts, and third-party ownership (PPA) options so you can choose the best fit for your budget.
