Directing the solar panels toward South allows for the highest opportunity for optimal Sun exposure throughout each day and year. As the seasons change, depending on your geographic location, this becomes more or less critical to the energy that could otherwise be harvested. The high altitude of the Sun’s path in the summer sky allows for more forgiveness for shallow sloped solar panels facing east, south east, west, or south west, as opposed the conventional approach of installing them facing direct south, as the sun travels much wider east and west than in the Winter. Conversely, the low altitude of the Winter Sun’s path requires a steeply sloped South facing solar panel to ensure that the Sun hours and angle of incidence are optimized for energy production. Attention to these details are vital for optimizing the performance of an off grid solar PV system.
