Calculate Energy Savings From Solar Panels

Solar savings payback calculator.

Calculate energy savings from solar panels.

At a minimum simply enter your postcode and the solar system size you are considering into the calculator. The calculator also allows you to compare a high quality photovoltaic pv system with a lower priced solar system and see the difference in payback time. Savings with a solar energy system for this scenario we assumed a monthly electric bill of 100 and an annual electricity rate increase of three percent. The net installation cost equals the total cost of going solar minus the 30 percent federal tax credit for solar.

Calculating how much money solar panels will save you requires knowledge of your power usage local electricity rates estimated solar production and any federal state and local solar incentives such as the 26 federal solar tax credit that affects the upfront cost of a solar system where you live. Then enter your typical annual electricity bill a guess is fine. Upon entering an address the tool analyzes factors such as shade roof orientation and local weather patterns to calculate how many hours of sunlight hit that roof in a typical year. This analyzed information is then combined to create an estimate for how much power a user could produce and can save with solar.

See how long it will take for a solar system to pay for itself. You can leave all the other inputs as their default values and hit calculate.
