Solar panels can be installed on the roof, which is currently one of the most common installation methods.
Rooftop installation can maximize the use of home space, avoid ground obstructions that block sunlight, and improve power generation efficiency.
However, before installation, factors such as the bearing capacity of the house, the weight of the solar panels and the installation method should be considered to ensure the safety of the installation.
In addition, local climatic conditions and environmental factors, such as wind speed, precipitation, etc., should be considered in order to select the appropriate solar panels and installation methods .
Is installing solar panels on the roof harmful to the human body?
No. Depending on the structure, the panel is fixed in different wayses. Some use pressure blocks, and others are attached directly to the support. The bracket is driven into the concrete roof structure using expansion bolts. The load capacity and wind resistance are very strong. Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays.
Dangers of photovoltaic energy production on the roof
It is not harmful to the human body to install solar panels on the roof.
Rooftop solar panels are devices that convert solar energy into electrical energy using photovoltaic power generation technology. The energy production process is based on the photoelectric effect, which converts the energy of photonsin energy of. of electrons and involves no harmful emissions In terms of material emissions, compared to traditional methods of energy production, such as coal-fired power generation or nuclear power generation, power generation Solar energy does not produce harmful substances such as carbon dioxide, sulphide or radioactive waste. , and has no negative impact on the environment and human health.
The dangers of rooftop photovoltaic power generation include:
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 aold 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 very high. If 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 production panelsuction of electricity are also subject 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, so that when the weather permits, they can provide sufficient energy. energy., but if it rains, normal electricity consumption will be affected.
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.
