Off-Grid Solar System Sizing Calculator

A solar system sizing calculator has been designed to help you determine the best system for your needs, and to make sure that you're getting a solution that's right for your budget and your lifestyle.

The solar system sizing calculator uses real data from our customers to give you an idea of how much energy your home will use, as well as what kind of financial impact installing a solar system will have on your household. It also shows you how much money each piece of equipment costs.

The calculator helps you determine whether it makes sense to install solar panels on the roof or if it's better to focus on the ground-mounted portion of your system instead. If you know exactly how many kilowatts (kW) of power your home needs each day, it can help you figure out which type of panel is best suited for your situation—and even tell you how long it would take before any monthly bills would go down if you installed a certain kind.
