If you are interested in solar power, you have probably heard about PV panels. The PV stands for Photovoltaic, and it is a specific type of power resource that is traditionally more reliable than the older style of solar panels. Not only this, but many times people have found that the PV panels can provide them with a more reliable and affordable source of power than going through a traditional electric source. Even though PV panels were originally invented in the 1950ís, it has not been affordable for large public consumption until very recently.
When they were first introduced, PV panels were primarily used as a source of power for the satellites in the space program. It works because the light that hits the panel is separated into three categories, the light that passes right through, the light that is reflected, and the light that is absorbed. It is the light that is absorbed into the paper thin wafers of the panel that is then turned into electrical current. The cells that are in the panel cannot store energy, they can only capture the energy from the sunlight, and then this energy later travels through the wires and into the base of the PV panels where it is then passed on as electrical current.
The PV panels that you see are not a single unit, but rather they are made up of a number of different modules that have been connected together. Sometimes these modules in a single panel can come from different manufacturers. In fact, it is a good thing about the design because it gives you the opportunity to expand your panel to fit your needs as you continue to depend more and more on the solar energy that is generated by the PV panels. If you are going to do this then you will just want to make sure that the rated voltage output between the modules matches so that they can operate together efficiently.
With the cost of traditional electricity prices on the rise it is only a matter of time before people are going to have to find a way to rely more and more on renewable alternative energy sources. The best way to do this if you live in a crowded area is to mount PV panels on your homeís roof. This way they do not take up precious space in your yard, and they are able to have an optimal chance to get the most sunlight possible. The good news is that as the technology has become more and more common, it is easier for the average person to get PV panels at an affordable rate.
In the beginning having PV panels mounted on your home may seem like a drastic measure, but they are an investment that are going to pay off many times over with the amount of money that you will be able to save when you no longer have to rely on the traditional energy sources.
