These homeowners in North Charleston wanted to be sure their system was installed by year end to take advantage of the 55% of combined federal and South Carolina state tax credits for solar. They were also interested in a battery back up system, but they decided to wait and add batteries in the future. Yes used 18 280 watt solar panels and a SolarEdge inverter with 18 Optmizers and monitoring to build the 5.04 kilowatt solar array on the front of the house. The actual installation only takes a couple of days, but getting permits before the project and interconnection after can add significant time, so we were pleased to finish it well before year end.
