Solar Energy – How Do Solar Panels Work?
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.
Pure silicone semi-conductor materials are currently used to produce solar panels. These materials discharge electrons when persuaded and influenced by solar power.
This establishes a voltage potential and an electricity flow. A photovoltaic 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.
For photovoltaic panels to work effectively, 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.
You can set up solar panels to meet your specific needs. DC systems at the 12 volt, 24 volt, and 48 volt ratings are the most common.
Solar panels can have a working life in excess of 20 years and they have an efficiency range of 12-14%.
