Grid Tie System Sizing

Determine the size of the solar panel array and grid tie system you will need.

Step 1:

How many kilowatt-hours (kwh) does your home/location use per month?

(This value is usually printed on your electric bill. If you don't have a bill, or don't know your consumption, click on 'load calculator' at the top of this page to go through the steps to determine this value.)

kilowatt-hours per month

Is your load (kwh) too high? Don't despair, our Experts can help you find other solutions that may help.

Step 2:

You need to determine the average number of sun hrs per day.

Select the State-City Closest to your location (currently only US states are provided)

Average sun-hours per day

Manually enter the average sun-hours for your location.

Step 3:

The total wattage of Solar Panels that you need is:

This value takes into account losses due to system inefficiencies.

Step 4:

How many solar panels do you need? That depends on the panel you choose.

Select the wattage of the panel your interested in, and see the results below:
