In fact, the risk of installing photovoltaic power generation on the roof is not particularly high, but it does have some disadvantages:
1. Impact on the load-bearing capacity of the roof
Because photovoltaic solar energy production requires solar cells. The semiconductor inside the panel produces a volt effect to produce electricity. However, the roof was not reinforced early in the design. Photovoltaic power generation equipment is relatively heavy, which can damage it. the frame, particularly in old houses. Roof damage.
2. Impact on the waterproof layer of the roof
When installing the photovoltaic power generation system, the brackets need to be drilled on the roof, which may damage the waterproof layer of the roof. roof, so if it is not replaced. If the waterproof layer is applied, water leakage may occur when'it's raining. Since there is a certain space between the screws and holes, the requirements of the waterproofing process are relatively high if the waterproof layer is applied. too thick, it will affect the installation. This will have some impact. If applied too thinly, it will have no effect and increase the risk of water leakage.
3. Light pollution
If there are relatively high floors nearby, some sunlight may be reflected into the building, causing light pollution.
4. Safety Issues
If strong winds occur, the photovoltaic panels may be overturned and subsequent maintenance costs will be relatively high.
