FAQs
What solar panel brands and technologies do you install in the Charleston area?
We work with Tier-1 manufacturers such as REC, Q CELLS, and SunPower, offering monocrystalline, bifacial, and half-cut cell technologies. All panels are UL-listed, meet South Carolina wind-load requirements, and come with 25-year performance warranties.
How does the coastal climate in Charleston affect solar panel performance and durability?
Charleston’s high humidity, salt air, and occasional hurricanes require panels with corrosion-resistant aluminum frames and robust glass. We use marine-grade stainless steel hardware and elevated racking systems tested for 140-mph winds. Annual output loss from heat and humidity is less than 2 %, and you can expect 1 400–1 600 kWh per installed kW each year.
Can solar power eliminate my electric bill completely?
A properly sized system can offset 90–110 % of your annual usage. Net metering with Dominion Energy or Berkeley Electric credits excess production at retail rates, so summer overproduction can cover winter consumption. Fixed fees (about $9–$15/month) usually remain on your bill even with full offset.
What incentives are available for Charleston homeowners installing solar?
Residential customers can claim the 30 % federal Investment Tax Credit (ITC). South Carolina also offers a 25 % state tax credit (capped at $35 000 or 50 % of state tax liability). Combined, most clients recoup 40–50 % of system cost. Additionally, property tax is not increased for solar improvements, and sales tax is exempt on solar equipment.
How long does it take from signing a contract to system activation?
Typical timelines are 8–12 weeks. Site assessment and design: 1 week. Utility interconnection and HOA approvals: 2–4 weeks. Permit review by Charleston County or the city: 2–3 weeks. Installation: 1–2 days. Final inspection and utility meter swap: 1–2 weeks. We manage each step and keep you updated through our online portal.
Do you offer battery storage, and is it worthwhile in Charleston?
Yes. We install Tesla Powerwall, Enphase IQ Battery, and Generac PWRcell systems. Batteries provide backup during grid outages from storms, enable time-of-use arbitrage if rates change, and can qualify for the same 30 % federal tax credit when paired with solar. In coastal South Carolina, a single 13.5 kWh battery can run critical loads (fridge, lights, Wi-Fi, and sump pump) for 10–12 hours; larger homes may opt for 2–3 units.
