Calculating Power Usage For Solar Panels

The tool works by taking your average monthly energy usage in kilowatt hours kwh.

Calculating power usage for solar panels.

Other factors such as shade location available panel space and seasonal use need to be taken into account. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142. The power generation capacity of a solar panel is given in watts. Solar power as a function of time in kwh or wh that your solar panel can produce taking into account its rated power and solar energy available at your place.

For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. Likewise if you wanted to account for 100 of your daily kwh consumption you would need 30 solar panels 37 kwh daily usage divided by 1 24 kwh per panel.

This is a very general system size estimation. Please note that solar panels are not 12v i repeat solar panels are not 12v. We want to help you get the system that s right for you. To calculate the energy it can supply the battery with divide the watts by the voltage of the solar panel.

This calculator may come in handy when you buy solar panel s for your rv vehicle boat camper or home solar system and you want to get a real. You calculate the power supplied or calculate a solar energy system output from the panel to the battery using its watts peak and exposure. Use our power use calculator to calculate how much electricity you use in kw hours and also the likely maximum power requirement in kw. Solar panels power generation is commonly given in watts e g.

120 watts 18v 6 6 amps. How to use a calculator to calculate how many solar panels you need. Please note that these calculations are based on assumed power consumption of various appliances.
