Geometrical Considerations for Solar Panel Installation on a Flat Roof
Geometrical considerations play a key role for solar panel installations. Solar panels can be installed on a light-weight support structure on the flat roof鈥檚 surface. Lightweight mounting frames with high mechanical integrity are readily available on the market. This installation option does not require puncturing of the roof for electrical cable connection between the solar generator and the inverter module because the inverter can be directly located under the solar panels. The inverter must be housed in a weather-proof container for longevity. Installation of the inverter directly on the flat surface requires the shortest connection cable between the solar generator and the inverter. In addition, optimum mounting configuration of solar panels is possible in terms of orientations and inclination. If the solar generators are mounted in rows on a flat roof, a minimum spacing between the rows must be maintained to prevent shadowing effects.
