Controllable factors that influence the efficiency of the solar panel
1. The type of panel material of the solar panel.
– Monocrystalline. This type of material brings one of the highest performance. The efficiency is rated between 17 per cent to 22 percent. This type of solar panels are the ideal ones for smaller roof tops in order to get higher efficiency. The cells are made of a single crystal of silicon, and because of that the electrons are able to easily flow, which causes one of the highest efficiency.
– Polycrystalline. Classified as a material that provides a middle level of efficiency, ranging from 15 and 17 per cent. This lower efficiency is caused because the electrons can not move as easily as monocrystalline, and because of that reason the efficiency levels drop.
– Thin film. This type of material can get one of the lowest efficiencies within solar panels, we can be talking about 10 and 13 per cent, even 10 points less compared to monocrystalline material. Because of that reason, you need to install more panels in order to meet the same energy need than with less monocrystalline panels.
The efficiency of the solar panels has a correlation with the cost, the most efficient you get the higher the cost of solar panels.
2. The inclination and orientation that the panels have been placed.
There is no homogeneous answer for this factor. The common denominator depends on each situation and location.
The further the solar panel is installed from the equator, the higher the angle should be. Based on the position of the sun, the solar tilt must be:
