Grid tied solar calculator


Welcome to the ipowersa On Grid Calculator. This calculator is designed to help you size a system for on-grid use. Simply go through the steps listed below, and you will get an idea of what you need for your system.


Step 1:

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

kilowatt-hours per month

What portion of your electricity usage (your "load") do you want to produce with a solar electric system?

You can adjust this portion by entering a percentage number below (don't bother typing the % sign).

Desired percentage of total loads offset by solar

Step 2:

Manually enter the average sun-hours for your location.

Step 3:

The total wattage of Solar Panels that you need is:

Watts, or kilowatts

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 you're interested in, and see the results below:

watts per panel

Results :

You will need panels for a total of watts.

You will need a On-Grid inverter that can handle watts
