what is the best roof direction for solar panels

The best roof direction for solar panels depends on your location and energy goals. In the Northern Hemisphere, south-facing roofs typically generate the most energy because they receive direct sunlight for the longest part of the day. This orientation maximizes efficiency and can significantly reduce electricity costs over time.

East and west-facing roofs are also viable options, though they produce slightly less energy. East-facing panels capture morning sunlight, while west-facing ones harness afternoon rays. North-facing roofs are generally the least effective in the Northern Hemisphere but may still work in some cases. The ideal direction balances sunlight exposure with your household’s energy consumption patterns.
