Solar panels convert light into electricity. The name of the type of energy fueled by solar power is called photovoltaics. The creation of photovoltaic energy is the primary purpose for solar panels.
Efficiency
-
Estimates for solar panel conversion of sun light into photovoltaic energy is around 14 percent to 22 percent. The rate of conversion depends on the type of solar panel that is being used.
-
Wear
-
Panels for solar conversion lose their effectiveness at a rate of 1 percent to 2 percent annually. The panels are expected to last for at least 25 years. The effectiveness of the panel depends on the manufacturer who assembles the panel and the type of silicon that is being used in the process.
Conversion
-
Solar cells form the basis of solar panels. A certain amount of cells make up one panel. Each cell is a small semi-conductor disk. These cells are attached to a wire and form a circuit. As sunlight hits the semi conductor the light is converted into energy. Solar cells are incredibly efficient because the abundance of sunlight is virtually unlimited.
Durability
-
Efficiency of panels also depends on their durability. The sun's energy degrades panels over time, and other types of weather elements play a role in wearing down the efficiency of the panels as well. Cleaning the panels of dirt and other debris also helps to improve their efficiency.
