Calculate The Cost And Size Of A Solar System For Your Home (Grid-Tie)

This calculator assumes your electricity rate is $0.12/kWh. To maximize accuracy, I recommend adding up all 12 monthly electricity bills for the year, divide them by 12, and the result will be your monthly average. This will factor in both your summer and winter electricity usage. Please note that solar system costs depend on the installer and equipment used.

Is the cost too high? The bulk of a solar system's cost is installation fees and 'soft costs', as explained by the DOE. They offer some tips for that.






The cost of solar system installation is heavily dependent on your area's climate. You can get an idea of how much sunshine each city can get here. The reduction of installation fees can be achieved by doing some of the installation yourself, but please check your local building regulations first.
