The basic answer is specific materials placed in direct sunlight will convert the light to electricity 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 discharge electrons when persuaded and influenced by solar power.
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.
Photovoltaic panels used to be only restricted and used in space age technology. Satellites and space stations generate reliable and continuous electricity with 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 living far from an electrical grid, more than a mile, are more likely to use photovoltaic technology, especially in residential homes. Power transmission cables are much more expensive to install than a solar panel power array. If the power grid is a considerable distance from your electric demand then it’s a good idea to consider solar energy for your power source.
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.
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.
The life expectancy of 12 volt solar panels is well over 20 years and they fall in the range of 12-14% efficiency.
