The estimated cost to install solar at your house is $30,537. We calculated this because we think your electricity usage for the year is about 11690 kWh, and a 8.65 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.68/W, which we get from Tracking The Sun.
The current electricity costs for National Grid are 19¢/kWh. So, by replacing 100% of your usage, you’ll save $2,243 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 8.95 years. If the costs of National Grid electricity rise 3%, then your savings will pay for your solar system in 8.69 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 1120 kWh in July, to a low of 700 kWh in December. For the entire year, we estimate that your 8.65 kW sized system would produce 11690 kWh.
You may be eligible for a state tax credit of $1,000, from the state of Massachusetts.
