Solar energy is undoubtedly an excellent way to lower electrical bills by making use of an ever-constant power source, the sun. Solar panels are usually costly to purchase, so quite often it is simpler to make them at home. Building solar panels is not easy, so you need to be sure to get the proper equipment and tools essential for the task.
Solar cells are usually made from silicon, but you can actually also create them from cuprous oxide. This particular substance is one of the first substances that was found to have a photoelectric effect, causing electricity to flow through a material. When building solar panels, you will need a range of different ingredients for this job, including a micro-ammeter, clip leads, copper, and metal snips. These items can be found at many hardware stores. A few home items are necessary also when building solar panels, like an electric stove, tap water, table salt, and sandpaper.
Start by cutting the sheet of copper employing your metal snips. Wash your hands to start with to get rid of any oil or grease. You must additionally wash the copper using a cleanser to eliminate any dirt. Making use of the sandpaper, thoroughly rub down the sheeting to get rid of any kind of corrosion or sulphide accumulation.
Position the dried and thoroughly clean copper onto your electric stove and put it on its highest heat. As the metal starts to heat, you should notice gorgeous shades and rainbow colours starting to form on the metal. Purple, orange, and red designs will start to coat the surface.
When the copper begins to get hotter, the colours disappear and then a black cupric oxide coating replaces them. This burnt layer will eventually flake off however, revealing the colours beneath. Once the burner begins to become red hot, the entire sheet of copper will be coated with a heavy black layer. Let the metal cook for half an hour, because a thicker coating is going to be able to flake off without difficulty.
Lift off the copper sheet and let it cool to room temperature prior to attempting to rub off the black layer. Lightly scrub the metal until all the black color is eliminated. Cut another sheet of copper and bend both pieces into a plastic jar, but keep them from coming in contact with each other. The cooked copper needs to be connected using the negative alligator terminal, even while the new one will need to get the positive terminal.
Combine heated water and table salt into the plastic container. Place this mixture into the sun, and you should see a moderate number of micro-amps in your current meter. Copper is a semiconductor, and that means you essentially have a working solar panel built from scratch.
