The risks associated with rooftop photovoltaic power generation are:
1. Damage to the roof structure. Photovoltaic solar energy production relies on the voltaic effect produced by semiconductors inside 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 can 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 photovoltaic power system brackets, you must first drill holes on the roof. Drilling will destroy the original waterproof layer of the house. If the waterproof layer is not redone, it will leak when it rains. a gap between screws and holes, the sealing process The requirements are veryIf it is too thick, it will affect the installation. Too thin and ineffective. The second waterproofing effect is much less effective than the first and will increase the risk of water leakage.
3. Produce mold. Photovoltaic panels installed on the roof generally cover the entire roof, but are not completely enclosed. After a while, mold is likely to grow 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 produce electricity by absorbing sunlight and converting solar energy resources. Therefore, when the weather is good, they can provide enough power, but if it is cloudy and rainy, the normal power consumption will be affected.ected. .
5. Security issues. In case of strong wind, the photovoltaic panels can be overturned. Especially if the battery panel is not firmly installed or the screws are rusty and aged, the battery panel may be blown away by the wind and subsequent maintenance costs will be higher.
It is generally legal to install photovoltaic panels on roofs to produce electricity.
The installation of photovoltaic panels and the production of electricity must comply with certain laws and regulations. Here are some relevant regulations:
1. Construction project planning permit: if the installation of photovoltaic panels involves. the reconstruction of a building or the construction of a new building requires first obtaining a building permit.
2. Industrial and commercial operating license: To install photovoltaic panels, yous must obtain an industrial and commercial license from a company; business license first;
3. Environmental impact assessment: If when the electricity generation generated by the installation of photovoltaic panels reaches a certain scale, an environmental impact assessment should be conducted and relevant approval documents should be obtained; /p>
4. Grid connection: Installing photovoltaic panels for electricity generation requires connecting the power to the grid, and you must first contact the local power grid company who requests grid connection;
5. Safety Production License: The installation of photovoltaic panels must meet safety production requirements and requires a safety production license.
Installing photovoltaic panels on the roof can provide the following benefits:
1. Energy savings: paPhotovoltaic panels can convert solar energy into electrical energy, which can reduce electricity consumption to a certain extent. To some extent, the cost, especially in sufficiently sunny areas, can achieve higher power generation efficiency;
2. Reduce dependence on traditional energy sources: Using photovoltaic panels to generate electricity can reduce dependence on traditional energy sources, thereby reducing dependence on traditional energy sources. environmental impact Energy impact and consumption are conducive to sustainable development;
3.Environmental protection and energy saving: using photovoltaic panels to generate electricity can reduce pollutant emissions, is environmentally friendly and conforms to the concept of low carbon and environmental protectionenvironment
4. Installing photovoltaic panels on the roof to generate electricity can increase the value and market competitiveness is conducive to real estate appreciation.
In summary, the installation of photovoltaic panels and the production of electricity must comply with certain laws and regulations. It is recommended to consult the appropriate departments or professional service agencies prior to installation to ensure compliance with applicable regulations.
