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, August is the highest-sun month in Wolfeboro with an average of 5.50 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 August in Wolfeboro:

5.50 kW/m2 * 25m2 = 137.62 kW/day available

137.62 * 19% efficiency = 26.15 kW/day captured

26.15 kW * 95% system retention = 24.84 kW/day usable

24.84 kW * New Hampshire average of $0.19 per kW * 30 days = up to $146.32 in savings in an average August.

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