The estimated cost to install solar at your house is $20,524. We calculated this because we think your electricity usage for the year is about 8820 kWh, and a 6.73 kW size solar system on your roof would replace 99% of your usage. We are using an estimated cost of $3.05/W, which we get from Energy Sage.
The current electricity costs for Modern Electric Water Company are 12¢/kWh. So, by replacing 99% of your usage, you’ll save $1,053 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 19.49 years. If the costs of Modern Electric Water Company electricity rise 3%, then your savings will pay for your solar system in 18.92 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 1090 kWh in July, to a low of 310 kWh in January. For the entire year, we estimate that your 6.73 kW sized system would produce 8730 kWh.
