Types of Solar Panels

Types of Solar Panels

Solar panels are a key element of a photovoltaic plant and their correct choice largely determines its efficiency. Depending on the method of production and the type of silicon involved in the composition of the panels, the following main types differ.

Polycrystalline

Polycrystalline solar panels - they are the most widely used as the production method is easier. In them the raw silicon is melted and then poured into square shapes. Their productivity is between 13% and 16% and they unlike single-crystal panels have a lower tolerance to high temperatures. At high temperatures, their normal functioning is sometimes disrupted, their service life is shorter and they require more space for the same amount of electricity produced compared to single crystal panels.

Monocrystalline Panels

Monocrystalline solar panels - are made of high quality single crystal silicon and have the highest efficiency and efficiency between 15% and 20%. This type of modules are made of silicone ingots with a cylindrical shape in order to optimize efficiency and minimize the cost of a single crystal cell which are cylindrical in shape. To optimize productivity and reduce the cost of a single-crystal solar cell, four sides are cut from each ingot and silicone plates are made. A single module can reach 300-380 Wp performance. They have the longest life and most manufacturers easily give a 25-year warranty on their panels. They require less space than other types of photovoltaics and produce four times more energy than lower class (amorphous) panels. Due to the complex production technology and their high productivity they are also the most expensive on the market.

Thin-layer (amorphous)

Thin-film (amorphous) solar panels - this type of modules are the most reasonable budget type and with the lowest performance. In the production process silicon is applied very tightly and thinly on a surface which is most often glass. What gives them an advantage over others is the fact that their effectiveness is not affected by the degree of sunshine. The high aesthetics, the homogeneous color and the fact that they are relatively weakly influenced by the temperature changes make them the most preferred solution for façade installations.
