How to prevent rural users from installing photovoltaic systems: In rural areas, concrete roofs are the main ones. When doing waterproofing treatment on the roof, the principle of "it should be guided but not blocked" should be adhered to to ensure that it can be used when water accumulates in heavy rains. Allow water to drain away smoothly to ensure the roof does not leak. After understanding this principle, during the installation process of photovoltaic brackets, we must first ensure that the bracket base is not arranged perpendicular to the drainage direction so as not to hinder the drainage of rainwater from the roof. Secondly, if the photovoltaic system is installed on an existing roof by directly placing a bracket base during construction, ensure that the base is placed smoothly and neatly, and measures need to be taken to fix it to avoid overturning, slipping, etc. It is also necessary to avoid the overlapping relationship between the base and the roof structure layer to ensure the safety of the structure. In addition, we should try to avoid drilling holes in the roof. For those situations where drilling holes is necessary to damage the original roof, we should adapt to local conditions and do different treatments according to different situations. If drilling holes in tiles, it is important to predict the depth first. After fixing the chemical anchor bolts, the location where the bolts pass through the tiles should be treated with waterproof sealant. This is very important.
Photovoltaic brackets are an important part of solar photovoltaic power generation systems and are mainly used to support and fix solar photovoltaic modules. Its functions include:
1. Support solar photovoltaic modules: Photovoltaic brackets can provide a stable support structure to fix solar photovoltaic modules in the appropriate position to ensure that they can work normally.
2. Adjust the angle of the photovoltaic module: By adjusting the angle of the photovoltaic bracket, the tilt angle of the solar photovoltaic module can be optimized to maximize the reception of solar radiation and improve power generation efficiency.
3. Resist wind and seismic forces: Photovoltaic brackets have good structural strength and can resist wind and seismic forces, ensuring the stability and safety of solar photovoltaic modules under severe weather conditions.

4. Easy maintenance and cleaning: The design of the photovoltaic bracket can facilitate maintenance personnel to inspect, clean and repair solar photovoltaic modules, and maintain normal operation of photovoltaic modules.
5. Provide cable ducts: Photovoltaic racks usually also provide cable ducts to transmit the power generated by solar photovoltaic modules to the inverter or grid.
In short, the function of the photovoltaic bracket is to provide support and fixation for solar photovoltaic modules, adjust the angle to maximize the reception of solar radiation, resist wind and earthquake forces, facilitate maintenance and cleaning, and provide cable ducts.
