The components of solar panels solar street light-litelsolar manufacturers

Let's take a look at the components of the photovoltaic panel: 1. Tempered glass, 2. EVA 3, battery sheet 4, EVA 5, back sheet 6, aluminum alloy protective laminate 7, junction box 8, silicone. What are the specific functions of these components, let us explain separately: 1. Monocrystalline solar panels The components of monocrystalline panels are the same, except that their cells are made of monocrystalline silicon. (Q: What is single crystal silicon? A: Single crystal of silicon. A crystal with a basically complete lattice structure. Different directions have different properties, and it is a good semiconductor material. The purity requirement is 99.9999%, or even More than 99.9999999%. It is used to manufacture semiconductor devices, solar cells, etc. It is drawn from high-purity polycrystalline silicon in a single crystal furnace.), the advantage of single crystal silicon is that the conversion rate is higher than that of polycrystalline silicon. Under the same area, it can be Generate more electricity! Reduced land rent and support costs. In terms of performance (attenuation, etc.), it is slightly better than polysilicon, but in terms of manufacturing cost, it is higher than polysilicon. Therefore, the price of monocrystalline solar panels is higher than that of polycrystalline silicon panels! 2. Polycrystalline solar panels The composition of polycrystalline panels is exactly the same as that of monocrystalline panels, except that the cells are made of polycrystalline silicon. After the introduction of polycrystalline solar panels, because of its low price and the performance gap is not very big with monocrystalline! The market has always been popular. And because of the continuous innovation of technology in recent years, the performance and conversion rate of polycrystalline silicon panels are not very far from polycrystalline, and they are almost negligible. However, there is a big difference in price (before the 531 New Deal, the price of single and polycrystalline can differ by a few cents per watt). Therefore, polysilicon is more popular in the market. (But after the 531 New Deal, due to the high price of monocrystalline solar panels and poor returns, the price reduction of monocrystalline solar panels is relatively large. As of November, the price difference of monocrystalline solar panels is not very big.) 3. Thin-film batteries The price of thin-film solar panels is still relatively high compared to silicon crystal panels. And the conversion rate has no advantage, but its influence on low light effect and sunlight shading is better than that of single and polycrystalline solar panels! It is more suitable for areas with poor geographical location and shaded areas all year round. We mainly produce and sell outdoor road, square, station, wharf, courtyard and indoor industrial and mining lighting fixtures.
