The hazards of rooftop photovoltaic power generation are as follows:
1. Damage to the roof structure. Solar photovoltaic power generation relies on the voltaic effect produced by the semiconductors inside the solar panels. If the roof structure is not reinforced at the beginning of the design. Since the photovoltaic power generation equipment itself is very heavy, it may damage the roof structure, especially if it is an old house, it is very likely to damage the roof.
2. Destroy the waterproof layer on the roof. To install the brackets of the photovoltaic power generation system, you need to drill holes on the roof first. Drilling will destroy the original waterproof layer of the house. If the waterproof layer is not remade, it will leak when it rains. Because there is a gap between the screws and the holes, the waterproofing process The requirements are very high. If it is too thick, it will affect the installation. Too thin and ineffective. The second waterproofing effect is far less effective than the first and will increase the possibility of water leakage.
3. Produce mold. Photovoltaic panels on the roof generally cover the entire roof, but are not fully enclosed. After a period of time, mold is likely to develop between the photovoltaic power generation panels and the roof, and the power generation panels are also prone to corrosion.
4. Affected by weather. The main working principle of photovoltaic power generation panels is to generate electricity by absorbing sunlight and converting solar energy resources. Therefore, when the weather is good, it can bring enough power, but if it is cloudy and rainy, normal electricity consumption will be affected.
5. Security issues. If strong winds occur, the photovoltaic panels may be blown over. Especially if the battery panel is not firmly installed or the screws are rusty and aged, the battery panel may be blown off by the wind, and subsequent maintenance costs will be higher.
