Solar panel energy savings calculator.

This solar calculator is known for its ability to forecast energy production for a specific array of solar panels on a specific roof in a specific location. Use the solar energy calculator for an idea as to the benefits you may see from installing a solar pv system. Estimates are based on your roof electricity bill and actual offers in your area. See how long it will take for a solar system to pay for itself.

Unless you have a solar battery any excess power that you don t use gets exported back to the grid. This tool gives estimates based on information you provide and a number of assumptions to indicate potential benefits. Solar panel angles explained. Using our tool we factor in.

This is the rate at which they generate electricity at peak performance for examples at noon on a sunny day. We refer to this as self consumption. But almost always the best angle to install your panels at is the angle that your roof is built at. Use this solar panel calculator to quickly estimate your solar potential and savings by address.

A lot of great work has been done by the national renewable energy laboratories and their pvwatts solar production calculator is considered highly accurate. The solar energy production side of solar savings forecasts is relatively predictable and solar panels production in each climatic area is well known and understood. This is to help you decide whether a pv system is for you. The optimum angle for your solar panels to get maximum annual energy yield is equal to the latitude of your location.

The below table converts solar energy production into greenhouse gas offsets using the metric converters 7 44 10 4 metric tons co 2 kilowatt hour of energy produced and the national average for solar panel production ratio 1 42 kilowatt hours watt of power. 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. The best way to make savings from solar power is to use as much electricity during the day when your panels are generating energy.
