The estimated cost to install solar at your house is $39,201. We calculated this because we think your electricity usage for the year is about 17340 kWh, and a 12.33 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 AMEREN are 17¢/kWh. So, by replacing 100% of your usage, you’ll save $2,960 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 13.25 years. If the costs of AMEREN electricity rise 3%, then your savings will pay for your solar system in 12.86 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 1710 kWh in July, to a low of 960 kWh in December. For the entire year, we estimate that your 12.33 kW sized system would produce 17340 kWh.
From Department of Energy Data, it looks like 2,453 homes have installed solar panels in your state, Illinois.
