OFF GRID CALCULATOR

The altE Off-Grid Solar Panel System Calculator helps you size the battery bank, watts of solar panels and the solar charge controller you need. The calculator assumes you will need to size your system to get you through average amount of sun-light in the least sunniest month of the year for your location. You still may want to consider a backup generator, however. Feel free to call our knowledgeable technical sales staff toll free at 877-211-8192 and have them help you find the system that fits your needs.
