Does photovoltaic radiation affect people?
Almost no.
Photovoltaic panels (solar panels) are devices that use solar energy to convert it into electrical energy. Its working principle is to use solar cells to convert sunlight into direct current, and then convert direct current to alternating current through an inverter for power supply. Photovoltaic panels differ from other household appliances in that they do not themselves produce electromagnetic radiation. There is therefore no risk of radiation for the human body when photovoltaic panels are installed on the roof.
However, in photovoltaic power generation systems, inverters and other electrical equipment can produce some degree of electromagnetic radiation. These radiations are generally very weak and do not cwill cause no harm to the human body if they are installed and used in accordance with current regulations and standards.
It is recommended when installing a photovoltaic power generation system to choose equipment that meets national and industry standards and install it in accordance with regulations to ensure human safety .
In addition, when using photovoltaic power generation systems, regular inspections and maintenance are necessary to ensure normal operation of the equipment, thereby reducing radiation risks.
In general, if the photovoltaic power generation system is installed and operated correctly, the risk of humans being exposed to electromagnetic radiation is low.
Do solar street lights have batteries?
No need. When solar panels are placed in the desert to produce electricityelectricity, on the one hand, photovoltaic panels are subjected to high heat, resulting in low electricity generation efficiency, so that they can no longer be used to generate electricity, on the other hand ; solar panels in the desert to generate electricity must ensure that the total construction cost caused by the smooth power generation of photovoltaic equipment is also relatively high, and the energy department often does not adopt it not.
When solar panels are placed in the desert to generate electricity, low power generation efficiency becomes a fatal flaw when overheated.Everyone should be familiar with solar generation. electricity by solar panels. Using solar panels to generate electricity is not only environmentally friendly. without any pollution, but also has low production costof electricity. The principle of energy production by photovoltaic solar panels is to use semiconductors to directly convert solar energy into electrical energy. In actual use, in addition to being able to be connected to the electrical network, it can also be used on a single building for small installations. use at scale. The biggest advantage of using solar panels to generate electricity is that they can still provide reasonable income on cloudy days and are favored by the electric power service.
On the surface, it seems possible to place solar panels in the desert to generate electricity. After all, sunlight in the desert can be well absorbed and used by solar panels. In fact, this doesn't work in practice. Commonly used photovoltaic solar panels have many advantages and characteristics.istics, but their most fatal disadvantage is that once overheated, their power generation efficiency will be low. Overheating is inevitable in the desert environment. The low power generation efficiency of solar panels makes it unnecessary to use solar panels to generate electricity. Therefore, energy agencies will not adopt the method of placing solar panels in the desert to generate electricity.
The cost of placing solar panels in the desert to generate electricity is high, so it is not easy to choose.If ordinary thick power lines are used to place solar panels in the desert, although the investment cost will be relatively low, but Due to the large cross section of such thick power lines, as long as the power generation efficiency is low, there will be almost no fluentin cross section. If you use ordinary fine wires, remember that the investment cost will increase slightly and the strength will be relatively large. Whether using a copper wire core or an aluminum wire core, when it is oxidized, the resistance increases and the energy generated is wasted.
To solve this problem, you can only use silver wire cores to replace regular wire cores. The use of silver wires can solve the problems of increased resistance and no current in the cross section, but the price and cost of silver, a precious metal, suddenly increases. If you choose to place solar panels in the desert to generate electricity, transporting and installing photovoltaic equipment requires a large fleet, relatively high labor costs, and metal-core wire precious and expensive money. The overall costl is enough for many power agencies to say “no.” ".
Placing solar panels in the desert to generate electricity will inevitably cause the lens of the panel to be covered with dust.Placing solar panels in the desert to generate electricity will result in the coverage of the panel lens by dust, although it is consistent with the above two reasons. The ratio is not the main factor, but it is also an inevitable problem that needs to be solved in a manner. reasonable. As you can imagine, in solar panel power generation equipment, the lens is an important light energy collection component. When covered with dust, it will definitely affect the normal light collection. and the energy production of the entire equipment
Judging from the current situation, it is useless to place solar panels.s in the desert to produce electricity. At least no electricity supply organization will adopt this method. However, according to relevant information, relevant scientists are also intensifying research on hybrid power generation system, hoping that the practice of placing solar panels in the desert to generate electricity can be realized at the future.
Yes. Batteries are integrated into solar street lights. Solar street lights use photovoltaic solar panels to convert sunlight into electrical energy. They charge solar energy collected during the day and can store electrical energy. The part that stores electrical energy is usually a rechargeable battery. These batteries can be charged with a charger or with photovoltaic solar panels. Rechargeable battery can store electricity for crazyProvide a light source to solar street lights at night or when light is insufficient. allowing it to continue to function.
