The estimated cost to install solar at your house is $16,693. We calculated this because we think your electricity usage for the year is about 6970 kWh, and a 4.78 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.49/W, which we get from Energy Sage.
The current electricity costs for Interstate Power and Light Co are 15¢/kWh. So, by replacing 100% of your usage, you’ll save $1,040 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 16.05 years. If the costs of Interstate Power and Light Co electricity rise 3%, then your savings will pay for your solar system in 15.58 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 710 kWh in July, to a low of 440 kWh in November. For the entire year, we estimate that your 4.78 kW sized system would produce 6970 kWh.
You are eligible for a federal tax credit equal to 30% of the cost of your solar system, or $5,008.
