Can I make a solar water heater myself? How to operate it?
Method 1:
The photoelectric conversion plate (silicon photovoltaic panel) can be used directly. But to have enough power, you need a large-area silicon light plate, which is expensive and bulky.
Method 2:
You can also focus on sunlight to heat the water and use water vapor to operate an generator to produce electricity. This technology is complex.
You can produce your own solar energy.
Prepare a large, thin-skinned plastic bucket (it's best to use a flat one, if you can't buy it, you can use a special plastic bag instead
Buy); black paint to paint it black, then turn it over or lay it on the roof, drill a hole in the seam, the size of the hole is the size of a dime
Buy a plastic water; pipe, the thickness should be the same as the hole size, connect it and use a lit plastic rope to seal the hole;
Connect the plastic tube downwards and place it where you want; want to take a bath.
