The most common types of mounting systems for PV panels are roof and ground-mounted systems. The roof mounting system is the cheapest and at the same time does not take up any space in the garden. Some people install the system on the ground, which gives more possibilities and usually guarantees higher power yields. Which installation of photovoltaic panels to choose?

Photovoltaics on pitched roofs

A pv roof mount brings many advantages. It is easy to install and inexpensive. The panels are then fixed with clamps, which are resistant to rust and high temperatures. The mounting installation should also take into account the ventilation of the modules and the routing of cables away from heated components. This is crucial for fire safety. For installation on a pitched roof to be feasible, the roof must have adequate roof truss strength.

Installing photovoltaic panels on a flat roof

The panels must still have a slope. On flat roofs, therefore, additional support structures are used, which position the modules at an angle of 10~15、20~35、30~45 degrees. The detailed inclination is determined individually for each building. A flat roof gives more possibilities because it does not depend on the direction of the house.

Installing photovoltaic systems on the ground

Higher yield is the effect not only of more favorable factors but also of better ventilation of PV panels. Ground-mounted photovoltaic systems use driven， screwed-on concrete foundations.
