Nowadays, many homeowners are turning to solar power as a way to reduce their monthly electricity bills in response to rising fossil fuel prices. By building Homemade solar panels, which is actually fairly easy to do, you can create even more savings.
The part of the solar power system that converts sunlight into electricity is the solar cell. If you know what type of power you need, you can get started, as solar cells, depending on how they’re connected, can generate virtually any amount of voltage and current.
There are two basic types of solar cells available. Made from a single large crystal, monocrystalline solar cells provided the highest level of efficiency. Thanks to its unified structure, a monocrystalline cell will be very reliable in addition to performing at such a high level of efficiency. Their durability makes them a better value in most cases, even though they usually cost a bit more than the alternative. The other common type of solar cell is the polycrystalline cell. Polycrystalline cells are less expensive, but they don’t generate power as efficiently as monocrystalline cells do.
The next step is to connect the solar cells together, making sure that it’s done in such a way that the needed voltage and current can be produced.
There are many DIY solar panel blueprints available, and most of these will have wiring diagrams. It’s important to follow the diagram closely. The individual solar cells should be mounted on a piece of thick plywood, so that they are facing the same direction. To see how big the backing board needs to be, just lay out the cells as shown in the wiring diagram. You can begin soldering wires to the cells after they’ve been mounted. Make sure that the wires are secured neatly to the backing board, and that they don’t block the cells’ access to the sunlight. Once this has been done, take the panel outside and check the voltage with a meter to make sure that everything is as it should be. If not, there may be a problem with the wiring. Complete the solar panel by adding sides and a transparent front to the backing. Use weatherproof caulking so that the enclosure is tight enough to deal with the elements.
Now, you can mount the panel in a spot that sees lots of sun exposure. The DC electricity produced by the panel can be used to charge batteries or power some small appliances. When you need AC power, you can obtain it by using a small inverter.
