Can I make a solar water heater myself?

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.

How to make simple solar panels at home

The simple method to create a solar power generation system is as follows:

1. Prepare several 6V monocrystalline silicon solar panels or12V, 2 maintenance-free batteries 6V or 12V and a 220V inverter

2. Switch on solar; Power panels Divide them into two groups. If it is a 6V power generation panel, first connect the two panels in series to increase the voltage to 12V. For other panels, first connect two panels in series, then connect those connected in series. panels in parallel to increase the current of the generator. Finally, attach the installed power generation panel set to the sheet metal, and install the two sets of generator sets in different directions;

3. Connect the electrode wires of the power generation group to the battery. The positive and negative poles of the battery can be connected to each other, so that the battery can receive a constant flow of charging energy if it needs to expand. battery life, a protection system against overloads ors over discharge can be installed, then the two groups of batteries can be connected in parallel to increase the battery current;

5. Finally, after enough sunlight has converted, connect the power supply to the inverter.

How to make a solar water heater

Handmade solar cells 1. Make titanium dioxide film (1) First put the titanium dioxide powder into a mortar and grind it with the binder (2) Then use a glass rod to slowly apply a film to the conductive glass (3) Put the titanium dioxide film under an alcohol lamp to sinter for 10-15 minutes, then cool it 2. Use natural dyes to color the dtitanium oxide. as shown in the picture. Put fresh or frozen black plums, mountain plums, pomegranate seeds or black tea, add a tablespoon of water and squeeze, then put the titanium dioxide film for coloring, it will take about 5 minutes until the film layer is formed. turns dark purple, if the film layer is not colored on both sides evenly, you can put it in and soak it for 5 minutes, then rinse it with ethanol and gently dry it with soft paper.

3. Making the positive electrode colored by the dye is the electrode from which the electrons come out (the negative electrode). The positive electrode can be made of a conductive surface of conductive glass (covered with a conductive film of SnO2), using a simple multimeter. You can find out which side of the glass is conductive. You can also use your fingers to judge that the driver's side ist rough. As shown in the picture, mark the non-conductive surface with "+", then use a pencil to evenly apply a layer of graphite to the conductive surface. 4. Add electrolyte. Use a solution containing iodide ions as the electrolyte of solar cells. It is mainly used to reduce and regenerate dyes. As the picture shows, just add one to two drops of electrolyte on the surface of the titanium dioxide film. 5. Assemble the battery. Place the colored titanium dioxide film face up on the table, drop one or two drops of electrolyte containing iodine and iodide ions onto the film, and then press the conductive side of the positive electrode face down onto the titanium dioxide. movie. Offset the two pieces of glass slightly and use two pliers to clamp the battery. The exposed parts of the two pieces of glass are used to connect the wires. This way, your cellthe solar is ready.

6. Battery Test Under outdoor sunlight, check whether your solar cell can generate current.

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

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 tofacilitate detection. of the water temperature.

4. Install the vertical post behind the support and cardboard. The height and inclination of this vertical pole can be adjusted as desired. 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 according to the weather of the day and connect the pipe from the water outlet to the place where hot water is needed.
