Economics

Tax creditsWhen NC companies buy Solar Farms here within the state they get 30% Federal Tax Credits along with 35% NC Tax Credits and the accelerated 5 year total system depreciation. NC companies are finding that they can usually pay for their Solar Farms by using these federal and state incentives that are currently being offered.

(Net AC kW output of solar farm) X (8,760 hrs per year) X (0.18 typical capacity factor) = annual kWhr output

1400 kW X 8760 hrs X 0.18 = 2,207,520 kWhrs per year (approx.)

kWhrs cost: $0.06 x 2,207,520 kWhrs per year = $132,451.00$4,000,000 Approximate cost of solar

DC -vs- AC Power

String Inverter -vs- Micro Inverter

String Inverter:“String together” a series of panels, which then feed current into the grid.

Micro Inverter:Take direct current from one solar panel and convert it into alternating current (A/C), which then mixes with output from multiple inverters and funnels to the electrical grid.
