11. Economics Tax credits When 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.

12. (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 field $2,600,000 65% tax credits $1,400,000 Total payback $ 132,451 10.5 Year payback

15. The Inverter is the BRAIN behind the operation DC electricity Converts AC electricity (to be used in your home or school)

16. DC -vs- AC Power

18. 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.
