Latitude-Based Angle Calculation. . Many U. In the Northern Hemisphere, south-facing surfaces traditionally offer the strongest solar yield, while north-facing angles receive less direct. . In most cases, the best direction for solar panels is facing south 1. Arrays that are appropriately oriented can improve energy output by up to 30% or more 2.
