Solar Power – How Do Photovoltaic Panels Work?

Certain materials react to the energy from sunlight and create and electric potential which can be used to power electronic devices. But it’s a bit more complex.

Pure silicone semi-conductor materials are currently used to produce solar panels. These materials eject electrons when placed in sun light. This creates a potential as well as flow of electricity. A solar panel is also called a ‘direct energy conversion device’ since all of these effects are taking place on an atomic level minus any moving parts.

Solar panels used to be only available in space age technology. The space station and satellites used them as a reliable conversion of solar power. Outer space has an advantage when it comes to solar energy since the sun’s radiation is, at the very least, 50% stronger out there than here on Earth. Solar energy devices have been used extensively in the space program.

Those who want to live in locations remote from the power grid are more likely to use a phtovoltaic system. Utility power lines can be significantly more costly to run than installing a local solar panel power system. It’s a good idea to consider solar power and your energy source if your are a long distance from the power grid.

For solar panels to work efficiently, a sunny location is mandatory.Beam radiation is the most effective since it’s is very direct light. Most of Western America qualifies…those states are good candidates for the use of solar energy, but northern climates and coastal states are usually quite cloud-laden and sadly, not worthy of 100% solar-reliance. You can search online for “solar insolation rates” to determine if your area is suitable for a solar energy system.

Specific needs and applications can be addressed with various solar panel set ups. DC systems at the 12 volt, 24 volt, and 48 volt ratings are the most common. Solar panels have efficiencies in the range of 12-14% and can have a life expectancy of over 20 years.
