Precautions For Roof Photovoltaic System Installation
Nov 17, 2022
The installation of photovoltaic systems on the roof can not only save electricity costs for the home, but also reduce environmental pollution and contribute to energy conservation and emission reduction. So is photovoltaic roof power generation stable? And what are the dangers of installing photovoltaic power generation on the roof?
The dangers of installing photovoltaic power generation on the roof include: damage to the roof structure, damage to the waterproof layer of the roof, light pollution problems, and safety problems.
1. Damage to the roof structure: Solar photovoltaic power generation relies on the volt effect generated when the semiconductor inside the solar panel is illuminated. If the roof structure of the house is not reinforced or planned to place heavy objects at the beginning of the design. Photovoltaic power generation equipment is very heavy. Excessive weight may have an impact on the roof structure. If it is an old house, it may damage the roof.
2. Destroying the waterproof layer of the roof: The installation bracket needs to drill holes on the roof. After drilling, it must be waterproof again, otherwise it will leak when it rains, but there is a gap between the screws and the holes. The technical requirements for waterproofing are very high. If it is made too thick, it will affect the installation. If it is made thin, it will have no effect. Moreover, there is no way to verify whether there is a water leak, and it often takes months or even years to appear.

4. Safety issues: In case of strong wind, the photovoltaic panels may be blown down by the strong wind. Typhoons in the coastal areas of our country can even blow down cars. If the solar panel is not installed firmly or the screws are rusted and aged, the battery board may be blown off by the wind.
Photovoltaic power generation will be affected by seasonal changes, weather conditions, day and night, and the intensity of solar radiation. Long-term rainy and snowy days, cloudy days and even changes in clouds will affect photovoltaic power generation. When there is no sun, power generation cannot be generated or the power generation is very small, which will affect the normal use of electrical equipment.
