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 Naval Anacost Annex with an average of 5.55 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 Naval Anacost Annex:

5.55 kW/m2 * 25m2 = 138.71 kW/day available

138.71 * 19% efficiency = 26.35 kW/day captured

26.35 kW * 95% system retention = 25.04 kW/day usable

25.04 kW * District of Columbia average of $0.13 per kW * 30 days = up to $100.90 in savings in an average July.

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