The basic answer is that certain materials are used to harness the sun’s energy and convert it directly into electricity which can be used to power electronic devices. But it’s a little more complicated.

Today’s solar panels are produced with extremely pure silicone semi-conductor material. Electrons are discharged from silicon semi-conductors when placed in sun light.

This establishes a voltage potential and an electricity flow. 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.

Not long ago photovoltaic panels were restricted to use in space age technology. Satellites and space stations generate reliable and continuous electricity with solar power. The sun’s radiation is 50% stronger in outer space giving solar energy an advantage in that environment. Solar energy devices have been used extensively in the space program.

Those living far from an electrical grid, more than a mile, are more likely to use photovoltaic technology, especially in residential homes. Utility power lines can be significantly more costly to run than installing a local solar panel power system. If you are a significant distance from an electrical grid then it’s a good idea to consider solar energy for your power source.

To generate cost effective solar power, a sunny location is neccessary. Beam radiation is the most effective since it’s the strongest.Most of the western united states qualify… those states are great candidates for using solar energy, but cloud-laden areas in northern climates and coastal states are not as worthy for 100% solar-reliance. You can search online for “solar insolation rates” to determine if your area is suitable for a solar energy system.

You can set up solar panels to meet your specific needs. The most common DC systems are rated 12 volt, 24 volt, and 48 volt.

Solar panels can have a working life in excess of 20 years and they have an efficiency range of 12-14%.
