Simple solar panels with their own hands.

A solar battery is called a universal device for round-the-clock conversion of solar energy into electrical energy. Now, a huge number of such devices can be bought at the appropriate stores. Only it is worth noting that the cost of such devices is far from the possibilities of the average static salary of a person. But such devices are characterized by high performance, since they are made of various specially processed solutions of silicon. In addition, high-quality solar panels are manufactured under the influence of high temperatures, and also require special cleaning and a large investment of money. But in exchange for the quality and efficiency of modern factory models, it is possible to make solar cells with their own hands from various materials at hand.

In this article, I will describe the manufacture of a solar battery, which is made from a small amount of copper oxide instead of solutions with silicon. We will describe all the necessary materials in which a homemade solar battery will work for greater efficiency:

1. A small sheet of copper from household materials. Usually the cost of such a sheet ranges from 150-160 rubles. Per square meter. In total, to make 2 solar cells with our own hands, we need about 10 square cm of such material.

2. Two universal clips like "crocodile" and a sensitive device - a microammeter, which will measure the electric current of our battery.

3. A modern electric oven or a gas cooker. This device we need to heat the structure, which is why it is best to buy a separate burner for 700 watts, at which the device can be heated to red.

4. 2 plastic bottles with cut necks. It is best to use an ordinary 2-liter bottle of some mineral water. Also, most likely, you need a few tablespoons of salt and water.

5. Universal sandpaper or drill with special abrasive nozzle. In addition, to secure the device, we use a roll of sheet metal.

How to make a solar battery with your own hands.

First, you need to cut a small part of the copper sheet, so that this piece was the size of the purchased electric plate hob. Then wash your hands and put on gloves to avoid leaving visible greasy spots and dirt on the appliance. Also, you need to wash the copper sheet with a special detergent. Thus, you will wash off all the fat or other stains from it, which will interfere with the manufacture of the battery and lead to loss of power.

In general, try to remove all dirt and stains. You can also use sandpaper or an abrasive brush type on the drill to completely remove and erase the copper coating on the cut sheet. Then lay the clean and processed copper sheet on the electric burner and turn it on to the maximum value. Copper on the tile will quickly heat up and oxidize, while you will see that beautiful red-orange spots begin to appear on the surface of the treated sheet. When the copper heats up to the highest temperature, these multicolored spots will turn into a black color of copper oxide. Such solar cells should not be touched with their own hands without cooling.

Cool the surface of the sheet slowly, while the copper will gradually shrink. The remaining parts of the assembly of solar panels with their own hands produce fairly quickly without much difficulty. The second sheet of copper is trimmed to the size of the first, and their parts are neatly joined together. After that, both sheets are placed in a bottle and the "crocodiles" are attached to both of these plates. Wire from one sheet of copper is connected to the plus, and the wire from the other plate with copper oxide - to the minus. Now 2 tablespoons of salt are mixed with hot water and gently poured into the bottle.
