Calculate Energy Savings From Solar Panels

Unless you have a solar battery any excess power that you don t use gets exported back to the grid.

Calculate energy savings from solar panels.

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. Calculations use the origin standing contract peak only tariff for your network distribution zone and may vary if you re on a time of use tariff. Use the solar energy calculator for an idea as to the benefits you may see from installing a solar pv system. See how long it will take for a solar system to pay for itself.

This is to help you decide whether a pv system is for you. Estimated savings include gst and include an estimate of how much grid electricity could be replaced by solar electricity and how much surplus energy you could export back into the grid. The best way to make savings from solar power is to use as much electricity during the day when your panels are generating energy. Adding a battery increases self consumption by using stored solar energy at night reducing your power bills even further.

This tool gives estimates based on information you provide and a number of assumptions to indicate potential benefits. Estimates are based on your roof electricity bill and actual offers in your area. 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. Using our tool we factor in.

Use this solar panel calculator to quickly estimate your solar potential and savings by address. This calculator adds these to find your total savings. Improved shade analysis powered by google sunroof data all estimates consider the shading and irradiance levels of every roof plane with the panel placement optimized for the most. 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.

We refer to this as self consumption. Essentially solar panels produce 77 56 less c02 per kwh of electricity. Solar co2 emissions solar panels produce an average of 88 grams of co2 per kwh from manufacture until they are defunct. Solar savings payback calculator.
