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.
Rooftop photovoltaic energy production project
It is always good to install photovoltaic energy production on roofs. If you install solar panels on the roof, you can efficiently use solar energy to generate electricity and save electricity. The state now provides subsidies for the installation of power strips. With solar power, we generally use less electricity, saving electricity for your home. The installation of photovoltaic energy production on the roof is relatively simple, generally speaking, eIt can be installed by a few workers in half a day.
1. Rooftop photovoltaic power generation is a mature technology that involves installing solar panels on top of the building and combining the existing building with the photovoltaic system. Use existing buildings efficiently without taking up additional land resources. It can generate electricity locally and consume electricity nearby, thereby reducing transmission losses. Photovoltaic power generation occurs during the peak electricity consumption period during the day, which can effectively alleviate peak electricity demand. The state actively promotes the possibility of producing electricity if solar panels are installed. Unused electricity can also be sold to the State Grid and benefit from corresponding subsidies. It can be connected to the electrical network, whichmeans that you must install two electricity meters in your home, one for the electricity supplied by the electricity company and the other for the electricity produced by the solar panels.
2. The construction of a photovoltaic plant requires support, which must be built on the roof or in an open space. Property rights to the roofs of urban buildings belong to all owners. If someone wants to build a photovoltaic plant on the roof of a building, they must not only obtain the consent of all owners, but also involve the property management company, urban management bureau, etc. unit. Many people in the city want to pretend, but it is not easy to do so. When installing, professional installers will design and install it reasonably according to the local climate. The photovoltaic plant will have no problem resisting winds strong of magnitude 8 to 10.
3. Since the photovoltaic power generation system requires drilling holes in the roof during installation, if it is improperly installed or handled improperly, it is easy to damage the roof, resulting in leakage accidents. water, mold, etc. ., and higher maintenance costs in the future. One of the most obvious disadvantages of installing solar PV power generation on your roof is that PV power generation destroys the waterproof layer of the house. The above is the answer to the question whether it is good or bad to install photovoltaic power generation on roofs and why.
The rooftop photovoltaic power generation project is an emerging renewable energy project that uses photovoltaic solar panels to convert solar energy into electrical energy to 'supply buildings withelectricity. This type of project can not only provide clean electricity to buildings, but also reduce energy costs and carbon emissions. This is an environmentally friendly and sustainable development method.
The implementation of rooftop photovoltaic power generation projects requires consideration of factors such as the structure, orientation and inclination of the building roof, as well as issues techniques such as the selection and installation methods of photovoltaic panels. Generally, rooftop photovoltaic power generation projects can be divided into two types: independent and grid-connected. A standalone rooftop photovoltaic power generation project involves connecting photovoltaic panels directly to a battery and storing electrical energy via the battery to meet the building's electrical needs. The product projectOn-grid rooftop photovoltaic power connects photovoltaic panels to the grid and sells the generated electricity to the grid for profit.

The advantage of the roof photovoltaic power generation project lies in its protection of the environment and its sustainable characteristics. First, it can reduce dependence on traditional energy sources, reduce energy costs and improve energy security. Second, it can reduce carbon emissions, reduce air pollution and improve environmental quality. Finally, it can provide renewable energy for buildings, achieve energy savings and reduce emissions and meet the requirements of sustainable development.
In short, photovoltaic energy production projects on roofs constitute aenvironmentally friendly and sustainable development method that can provide clean electricity to buildings, reduce energy costs and reduce carbon emissions. This is an important direction for future energy development.
