Solar panels installed on the roof will not radiate towards people. Since the solar water heater absorbs energy from the sun, it does not emit any electromagnetic waves or other energy. At most, the outer shell of a. poor quality will heat up. The heat of water is just a kind of infrared scattering, and infrared energy is our thermal energy source. As long as you are not burned, it will not harm people.
Solar cells, also known as "solar chips" or "photovoltaic cells", are optoelectronic semiconductor sheets that use sunlight to directly generate electricity. Simple solar cells cannot be used directly as energy sources. To realize power supply, multiple solar cells need to be connected in series, parallel and tightly sealed in the components. A solar panel (equalcalled solar cell module) is an assembly of several solar cells. It forms the core part of the solar power generation system and is also the most important part of the solar power generation system.
Let me answer you:
What can be installed is internal pipes. The pipes will not provide any insulation effect, but they are better than external pipes. not even one degree Celsius difference), if you are worried about the difference, you can wrap a layer of insulation foam or insulation cotton outside the pipe.
As for the pipes you mentioned , they are all made of “aluminum-plastic pipes”. The outer layer is plastic and the inner layer is aluminum. Its advantage is that it is easy to bend into various shapes, can withstand strong pressure and will not suffer from freezing. cracking. As for the tartar problem,It has nothing to do with the material of the pipe you use!
