Solar Power Savings by Month in Windsor
A 5kW system will save someone in Windsor up to $119.65 on an average month. That's significant given the average Massachusetts power bill of $119.26 per month. Here’s a monthly breakdown:
|Month||Available kW / m2 / day||Max savings / month|
Data based on 1 zip in Windsor, MA. Data reliability is rated excellent.
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 Windsor with an average of 5.36 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 Windsor:
5.36 kW/m2 * 25m2 = 133.98 kW/day available
133.98 * 19% efficiency = 25.46 kW/day captured
25.46 kW * 95% system retention = 24.18 kW/day usable
24.18 kW * Massachusetts average of $0.20 per kW * 30 days = up to $149.94 in savings in an average July.
These assumptions are very good for the average home in Windsor, but nothing beats the accuracy of getting your own quote.
