Which Way Should Solar Panels Face. Most installers offer a free solar analysis, which can set you on the right track for what direction you panels should face. In other words, if you’re at 35 degrees latitude, set your panels at a 35.
Solar modules that face east are similar to west facing panels in producing around 15% less electricity overall than north facing ones, but they will produce more electricity. The rationale is pretty simple. Solar panels produce more energy when minimizing the angle of attack.
