Choose the Right Power for Your Project select your zone

To determine how many watts you need, select your solar zone and the time desired from the charts shown here. Wattage for each zone is calculated based on peak sunlight hours in the worst weather month of the year, based on 30 years of weather data.

Solar Zones

Our kits are designed for three-day autonomy. In order to do this, we design for the amount of hours of peak sunlight a certain region gets in a day. Use the map  to determine which zone you are in, and include that information in the contact form. If you are not sure which zone you are in, we can help you figure that out.
