If as an alternative energy source you choose to buy cheap chinese solar panels, be prepared that the photoelectric elements of the modules are made of amorphous or polycrystalline of silicon. This explained the difference in price, the efficiency and timing of solar batteries.
The life of monocrystalline solar panels is due only sealing materials . Uniformity switchgear Lenia electrical properties allows to increase the efficiency up to 18-20% single crystal silicon is resistant to chemical, atmospheric and climatic aggressive impact on air covered with a protective oxide film that is transparent to infrared and visible spectrum insolation.
In recently, sale there were the so-called multicrystalline silicon solar panels. not to be confused with the single crystal.
In fact, this polycrystalline or amorphous solar cells, but for the purpose of substitution of concepts and greater fonetich . Tion similarity with monocrystalline solar panels name changed. After several years of operation, these batteries have to be changed.
Types of solar panels can be divided into two conditional categories:
The first to work. The thickness of the photovoltaic elements provides deep photon and electron emission elaborate life .
Second for sale. Solar cells which tend to foil thickness. With all the attendant. It is to this tend to cheap chinese photovoltaic panel.
It is of great importance and structure of the glass surface on which solar cells are laminated. Smooth glass reflects part of the direct solar radiation and a large portion of the scattered. Textured, nizkoreflektornoe - gathers diffuse light and does not reflect the direct sunlight. Power input optical radiation is increased by 12-15%. This increases the efficiency of solar cells especially in cloudy weather, which is important in our climatic conditions. Tempered glass on the order increases the reliability of solar design.
High-quality solar cell - the ideal source of energy.
