The estimated cost to install solar at your house is $69,702. We calculated this because we think your electricity usage for the year is about 29760 kWh, and a 22.85 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.05/W, which we get from Energy Sage.
The current electricity costs for Avista Corp are 12¢/kWh. So, by replacing 100% of your usage, you’ll save $3,673 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 18.98 years. If the costs of Avista Corp electricity rise 3%, then your savings will pay for your solar system in 18.43 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 3860 kWh in July, to a low of 1130 kWh in January. For the entire year, we estimate that your 22.85 kW sized system would produce 29760 kWh.
You are eligible for a federal tax credit equal to 30% of the cost of your solar system, or $20,911.
