Most buildings are suitable. They simply need to meet the following requirements: 1. There must be enough available, unshaded space. As a rough rule of thumb, allow about 0,5 square meter for every 100 Watt (if you use standard commercially available solar panels). Approximately 4-5 sq.m/kWp is needed for a tiled roof and 10-12 sq.m/kWp for a flat roof or plot, because on flat surfaces the solar panels are installed in rows spaced apart to prevent them from shading one another. Make sure the area is as close as possible to 100% unshaded throughout the day. Otherwise, your system will operate less efficiently.
A rough rule to make sure your system does not produce less due to shading is that the distance from any obstacle (building, tree, etc.) should be twice the height of the obstacle. 2. Solar panels perform best when facing south. Deviations from south are acceptable, but they reduce output. 3. The solar panels must be tilted correctly relative to the horizontal plane.
A tilt is usually chosen to provide the best results throughout the year. In Greece, the optimal tilt is around 25 -30 degrees. Don’t worry, though. Our installation team will determine the correct tilt.
