A rooftop solar power system has various components include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories.

A solar hybrid system (either on-grid or off-grid) combines other power components like diesel generators, wind turbines, batteries etc. They are capable of providing a continuous source of power.

Installation method of roof photovoltaic system

Nowadays, there are several types of roofs for solar photovoltaic power generation, among which sloping roofs, flat roofs, and color steel roofs are more common. The installation conditions of the roof should determine the utilization area, shelter, waterproof, load bearing, etc.

Firstly, determine the usable area of the roof, because the usable area directly determines the installed capacity of the photovoltaic system.

Secondly, it is necessary to pay attention to the orientation of the roof. If the roof faces south, it will receive more solar radiation and the power generation will increase. Finally, it is necessary to consider whether there are tall buildings around, waterproofing of the roof, etc. The shelter of tall buildings will affect the lighting, and a good waterproof system may prolong the life cycle of the power station.

1. Installation method of pitched roof

Photovoltaic modules are mainly installed along the slope and overhead, and the vertical distance between the modules and the roof meets the requirements for installation and ventilation and heat dissipation gaps. The photovoltaic array is laid parallel to the roof, and the bracket adopts steel embedded parts to fix the beams in a lattice.

2. Installation method of flat roof

The structure selection of the flat roof can be based on the actual practice of the finished surface of the roof, and the corresponding support system can be selected, and the inclination angle corresponding to the maximum value of the local annual total power generation can be used as the installation inclination angle of the bracket. In addition, the waterproof layer of the photovoltaic system on the flat roof is very important. Waterproof membranes, cement mortar protective layers, ceramic tiles, etc. should be used to do a good job of waterproofing.

3. Installation method of color steel roof

Color steel tiles are generally used in family factories or large industrial plants. The difference between its installation method and the slope roof lies in the installation method of the support. If the structural bearing capacity of the roof is satisfied, the inclination angle can be raised to increase the installation angle.
