Introduction How to Make a Solar Water Heater 1. Prepare the Materials First of all, you need to prepare the following materials: solar panels, PVC pipes, tees, elbows, internal tooth joints, glue, insulation pipes and paint.

How to make a solar water heater

1. To prepare the materials, you must first prepare the following materials: solar panels, PVC pipes, tees, elbows, internal joints, glue, insulating pipes, paint, electronic thermometers, old iron sheets, plastic foam and old sponges wait.

2. First find solid, good quality wood and simply make a 2.1X1.2m frame. Then transform the T-pipe into a hot exhaust pipe of the same type as the water heater device. Then pour foam over the frame and paint the foam and the old iron sheet black.

3. Connect the shelf made of solar panels to the thermal tube. Note that the pipe must be installed with an insulating tube. If you have an electronic thermometer, you can install an electronic thermometer for easier detection. of the water temperature.

4. Install the vertical post behind the support and cardboard. The height and inclination of thisVertical pole can be adjusted at will. Then the glass tube is filled with water and the glass tube is first sealed and then placed on the rack. Then adjust the pole, observe the direct angle of the sun and adjust the pole to the corresponding height. The larger the area exposed to the sun, the better.

5. When adjusting the concave arc of the pole, you should do it on the roof of a building exposed to the sun or in a high place. The reflection of the sun focuses on the glass tube. better effect. Then simply attach the bracket.

6. After a while, the homemade solar water heater can use the principle of cold water flowing and hot water floating to check the water temperature. Then wait a while, then check the amount of hot water obtained. You can also fill the homemade solar water heater with an appropriate amount of water depending on the weather of the day and connect the water pipe.has water outlet where hot water is needed.

First of all, there is no such thing as bicrystalline silicon. Nowadays, solar power projects mainly include monocrystalline, polycrystalline, amorphous, cadmium telluride and other thin-film cells.

The conversion efficiency of monocrystalline silicon is about 14% to 17%, and that of polycrystalline silicon is 13 to 15%.

There is no difference between polycrystalline silicon solar cells and monocrystalline silicon. solar cells. Polycrystalline silicon solar cells and monocrystalline silicon solar cells have a very good lifespan and stability. Although the average conversion efficiency of monocrystalline silicon solar cells is about 1% higher than that of polycrystalline silicon solar cells, since monocrystalline silicon solar cells do notcan only be transformed into a quasi-square shape (the four vertices are arcs), when forming a solar cell module. When part of the area cannot be filled, polycrystalline silicon solar cells are square and do not have this problem, so the efficiency of solar cell modules is the same.

In addition, due to the different manufacturing processes of the two solar cell materials, the energy consumed in the manufacturing process of polycrystalline silicon solar cells is about 30% lower than that of polycrystalline silicon solar cells. monocrystalline silicon

Upstairs The weak light effect mentioned is amorphous silicon, not polycrystalline, only in the case of 0-50w/m2
