The estimated cost to install solar at your house is $46,954. We calculated this because we think your electricity usage for the year is about 22000 kWh, and a 15.6 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.01/W, which we get from Energy Sage.
The current electricity costs for Potomac Edison are 5¢/kWh. So, by replacing 100% of your usage, you’ll save $1,002 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 11.61 years. If the costs of Potomac Edison electricity rise 3%, then your savings will pay for your solar system in 11.27 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 2060 kWh in August, to a low of 1450 kWh in December. For the entire year, we estimate that your 15.6 kW sized system would produce 22000 kWh.
