Are there so many negative aspects to solar panels?

Solar panels are a type of clean and renewable energy that converts sunlight into electricity. However, with the popularity and widespread use of solar panels, there are increasingly doubts about the use of solar energy, and many people also feel that it has many hazards. Now let's explain one by one whether these hazards are real.

Will solar panels emit radiation during use, causing harm to the human body?

Radiation "is something we know in our daily lives, usually referring to harmful effects on the human body. It can easily cause genetic damage and increase the probability of cancer. For example, electronic radiation (such as mobile phones, computers, iPads, etc.) is everywhere in our lives, and only these harmful radiations are worthy of our vigilance. Radiation is the process of emitting or transmitting energy in the form of waves or particles in space or material media.

From this, we can understand that radiation is the process of emitting and transmitting energy, in the form of waves (such as light, sound, radio waves, etc.), or in the form of particles.

As mentioned before, solar panels generate electricity by converting solar energy into electrical energy through semiconductors, and converting direct current into alternating current through inverters. However, no harmful substances are produced, so solar panels do not produce short wave radiation, which is why they do not produce harmful radiation to the human body.

2. Is it difficult to clean solar panels?

As mentioned before, the main body of solar panel power generation is also solar cells, so the selection of surface materials is high transparency materials.

Firstly, regularly inspect the solar panels. Generally speaking, there is no need to clean them too much. When it rains, rainwater will wash away some dirt and stains. When the surface of the solar panel reaches gray and accumulates thick, and the blue solar cells cannot be seen clearly, it is time to clean the surface of the solar panel.

When the surface of the solar panel is made of glass, a soft brush and clean and gentle water can be used for cleaning. There is no need to use too much force to cause scratches on the surface. If the surface of the solar panel is made of other materials and is only pure dust, then simply clean the surface with a feather duster.

3. Can solar panels generate electricity once installed?

No, first of all, you need to figure out the positive and negative poles of the solar panel. Don't connect them incorrectly, otherwise it won't charge properly and seriously burn out the diode, causing a short circuit in the solar panel and causing a fire.

Secondly, attention should be paid to the orientation of the solar panels to ensure sufficient sunlight and achieve maximum power generation. It is best to face south (the orientation installed at home may not be so accurate, and a difference of about 20 degrees is generally not a problem). This is the direction with the highest intensity of solar radiation in China, usually from 9 am to 14 pm in the morning.

Pay attention to the surrounding installation environment and do not place it in areas with large shade of trees. This not only makes it easy for fallen leaves to fall onto the surface of the solar panel, but also seriously affects its illumination duration.

Finally, the tilt angle of the solar panel is usually determined based on the latitude of the Earth. Generally speaking, the closer it is to the north, the greater the tilt angle, and the closer it is to the south, the smaller the tilt angle.
