  • 30% federal incentive extended to 2019
  • Average grid electricity costs ($0.11 per kilowatt-hour) make solar viable

Savings Methodology

We estimate savings with a system that is very efficient at 19% of energy captured with a standard 5% total system loss. System loss comes from both the unavoidable (system age, electrical dissipation in wiring and connections, etc.) and the avoidable (shade from trees, dust, etc.) Do note that the system will b e slightly less efficient as it ages, too.

For example, July is the highest-sun month in Faith with an average of 6.56 kW per meter per day. An efficient 5 kW system will cover about 25 square meters depending on the roof. So, the following is the savings calculation for July in Faith:

6.56 kW/m2 * 25m2 = 163.93 kW/day available

163.93 * 19% efficiency = 31.15 kW/day captured

31.15 kW * 95% system retention = 29.59 kW/day usable

29.59 kW * South Dakota average of $0.11 per kW * 30 days = up to $100.90 in savings in an average July.

These assumptions are very good for the average home in Faith, but nothing beats the accuracy of getting your own quote.
