There’s a simple rule of thumb for finding the azimuth angle for solar panels: Face them true south in the northern hemisphere and true north in the southern hemisphere. But how do you find true south or true north? After all, compasses point towards magnetic north. It’s actually quite easy. I’ll cover the free tools […]| Footprint Hero
In most parts of the US, solar panel cleanings usually aren’t worth the money because the extra savings you get from cleaning your panels is unlikely to make up for the cost of the cleaning. In most cases, you can just let rain clean your solar panels naturally. However, in certain parts of the southwest […]| Footprint Hero
