Calculate Solar Panel Size

Solar panels are available in various sizes to fit energy needs of your home. Size of the solar system depends on the amount of energy you want to produce. For example, if there are two houses with the same square footage, they can still require different sized plates to cover their diverse energy needs.

The determinant of panel system for your home takes a few minutes. Look at your home electricity bills for last year. If you are unable to find them, you can make your E-service provider requests duplicate copies of invoices issued, or they can through your service provider’s site are available.

Calculate Solar Panel Size

Note kilowatt hours used on each electric bill. These figures will most likely be in hundreds. Usually, figures for summer months are greater than those for winter season due to greater power consumption in summers fans, air conditioners etc .

Calculate average kilowatt hours used at your home per month. Add total number of kilowatt hours used for one year, then divide answer by 12. Figure out kilowatt size of solar panels required at your home.

Simply divide average kilowatt hours you calculated in Step 3 by your average monthly hours of sunlight see Resource link to determine your average number of sunny hours per day . Let’s suppose your average monthly kilowatt hour consumption is 347, while average monthly hours of sunlight is 155. Your home would need panel system that produces 2.2 kilowatts per hour.

Measure size of your roof and figure out how many panels you need. Let’s say you pick solar panel that produces 125 watts. To produce 2.2 kilowatts per hour, you will need 17 panels. average dimension of panel that produces 125 watts is 59 inches by 26 inches by 2 inches.

This size depends on number of solar cells installed on it, panel that produces 100 watts will obviously have fewer cells and will measure about 56 by 22 by 1 inches. Similarly, size will vary slightly according to watts produced by each panel. However, once you have figured out size of panel system required determined in last step , it will be easier to choose panels.

You must have exact measurements of your roof so you can decide panel size accurately. If your roof is small, you will need panels that produce more energy. size difference between 100-watt panel and 125-watt panel is not great, but you will obviously have to install more panels if you choose 100-watt version.
