What is a solar panel? How does it work?
If you really want your power to be independent, there is little choice in the form of solar panels solar electric panels, hot water heating and passive wind turbines for electricity production and grinders wind to pump water and hydroelectric generators.
A good rule of thumb is that once you eliminate the use of electricity for space heating, water heating and cooking (electric cookers) Most homes can be successfully operated from a solar, wind, or hydro system.
What is a solar panel?
Solar panels generate free energy from the sun by converting sunlight into electricity with no moving parts, no emissions and no maintenance. The solar panel, the first component of a solar energy system, is a collection of individual silicon cells that produce electricity from sunlight. Photons (light particles) to produce an electric current as they hit the surface of thin silicon wafers. A single solar cell produces only about 2.1 (0.5) of one volt. However, a typical 12 volt panel about 25 inches by 54 inches contains 36 cells wired in series to produce about 17 volts peak output. If the solar panel can be configured to output at 24 volts, there will be 72 cells for the two groups of 12 each of 36 volts can be wired in series, usually with a jumper, allowing the solar panel to the output 24 volts. When under load (charging batteries for example), this voltage drop from 12 to 14 volts (for a configuration of 12 volts) resulting from 75 to 100 watts for a panel of this size.
Multiple solar panels can be connected parallel to increase current capacity (more power) and wired in series to increase voltage of 24, 48 or even more power systems. The advantage of using a higher voltage output of solar panels is that smaller wire sizes can be used to transfer electrical energy from solar panel to charge controller and batteries.
Basic types of solar panels
Monocrystalline Solar Panels: The panels are most effective and expensive solar cells are manufactured with monocrystalline. These solar cells based on pure silicon and involve a complex process of crystal growth. Long rods are made of silicon that are sliced from 0.2 to 0.4 mm thick discs or wafers which are then transformed into individual cells that are interconnected in solar panels solar panel.
Polycrystalline: Often called multi-crystalline solar panels made of polycrystalline cells are slightly cheaper and slightly less efficient than monocrystalline cells, because cells are not grown in single crystals, but in a large block of many crystals. This is what gives this striking appearance broken glass. As monocrystalline cells, they are then sliced to produce cells that make up the solar system panel.
Amorphous solar panels: These crystals are not really, but a thin layer of silicon deposited on a base material such as metal or glass to create the solar panel. These amorphous solar panels are much cheaper, but their efficiency is also much less more square feet is needed to produce the same amount of energy than monocrystalline or polycrystalline solar panel. Amorphous solar panels can even be made into long sheets of roofing material to cover large areas of a roof facing south surface.
you planning to install solar panels for your home?
Solar panels can be a good investment that not only saves you money and increases the value of your property, but also helps the environment, it helps your wallet and bank can probably account.
You ask in trade for solar panels are very expensive. Alternatively, you can build your own solar panel, if you can do some work handyman. home solar panels are much cheaper compared to their counterparts in the trade done. The solar panel is really not as complicated as you think. To build a solar panel you will need some basic materials and a budget of about $ 150 – $ 200 a solar panel that you want build.

It’s not that tough to making solar panels at home but it’s not something you can do in 10 minutes either. It’s not like you need to know quantum physics or anything like that. Visit http://www.squidoo.com/7-simple-steps-to-making-solar-panels
