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 “Online Test Drive” tool simulates hour-by-hour performance of any sized solar power system with loads and weather conditions that you can set. Evaluate if your panels and batteries are adequate for different loads. Use the presets for our packaged systems, or click the “advanced” button to override and simulate any size system. Here’s a walk-through on how to use the online test drive tool.

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 account for that.
