The estimated cost to install solar at your house is $23,019. We calculated this because we think your electricity usage for the year is about 8820 kWh, and a 6.45 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.57/W, which we get from Energy Sage.
The current electricity costs for Central Maine Power Company are 30¢/kWh. So, by replacing 100% of your usage, you’ll save $2,680 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 8.59 years. If the costs of Central Maine Power Company electricity rise 3%, then your savings will pay for your solar system in 8.34 years.
Solar installed at your house would generate different amounts of electricity during different months. We estimate that your production would vary from a high of 870 kWh in July, to a low of 540 kWh in November. For the entire year, we estimate that your 6.45 kW sized system would produce 8820 kWh.
The state of Maine generally uses Full Retail Rate for net metering. This means that when you produce more electricity than your house uses, the utility will pay you Full Retail Rate for the extra electricity.
