Solar Electric Panels

Photovoltaic (PV) panels, which use sunlight to produce electricity, are much more efficient for their purpose than their solar thermal cousins. They are also much more useful in northern climates. While the manufacturing process and the mechanism by which they work is more technical than solar thermal, they are much simpler to install and maintain in actual use. Following is an overview of the function and purpose of photovoltaic panels, as well as the many benefits they have in alternative energy systems.
Solar panels are one of the most popular sources of alternative energy for home power systems. Everyone sees some sun during the year, which means everyone can gain some benefit from solar power, whether to run a whole home power system, or just charge some batteries with free electricity.
Solar power is one of the simplest forms of renewable home power. Photovoltaic (PV) panels have no moving parts, and need no complicated control mechanisms. Solar panels are the closest thing to a "plug and play" independent power source you'll find.
The sun will be a reliable source of energy for the earth for billions of years to come. In our part of the world solar energy is available all year round, even when the sky is overcast. And thanks to technical progress everybody can now capture this energy for themselves without causing pollution or other undesirable emissions.
