The estimated cost to install solar at your house is $39,408. We calculated this because we think your electricity usage for the year is about 16700 kWh, and a 12.39 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.18/W, which we get from Energy Sage.
The current electricity costs for Commonwealth Edison are 16¢/kWh. So, by replacing 100% of your usage, you’ll save $2,732 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 14.43 years. If the costs of Commonwealth Edison electricity rise 3%, then your savings will pay for your solar system in 14.01 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 1730 kWh in July, to a low of 970 kWh in December. For the entire year, we estimate that your 12.39 kW sized system would produce 16700 kWh.
The state of Illinois generally uses Retail Supply and Delivery Rate for net metering. This means that when you produce more electricity than your house uses, the utility will pay you Retail Supply and Delivery Rate for the extra electricity.
There are 15 solar installers that operate in Illinois. WattBuy recommends EnergySage, Modernize, Palmetto, RGR Marketing, and Sunrun.
