Online Tools to Help you

We have a whole section of this website which will walk you through all the design considerations for an off-grid solar power system of any size. We also have tools to help you predict the performance of solar power systems.

Our unique Solar Insolation Lookup Tool (SILT) predicts power output from a solar panel for any location in the world. It provides more specific information than the World Bank’s Global Solar Atlas which only gives annual averages. SILT uses NASA data to give you month-by-month predictions of solar output from your panels. When living off-grid you don’t care so much about average yearly output, but need to know how much energy you’ll have during that cloudy time of the year. SILT will tell you that. Plus you can align you panels an any orientation you choose and SILT will also predict for that. For detailed help using the SILT tool, see the SILT Help file.
