Interpreting Different Types Of Solar Panels
After years of development of solar energy, the solar charging technology has also undergone tremendous changes. From the original polycrystalline silicon solar panels, single crystal silicon solar panels, semi-flexible solar panels to thin-film solar panels, the technology of solar panels is becoming more and more mature, and more and more The more suitable for life applications, the efficiency and efficiency of charging have also been greatly improved. From the initial conversion rate of only 8% to the current conversion rate of 24.2%, SUNPOWER solar panels allow solar charging in the next 3-5 years. The popularity is here!
Polycrystalline and monocrystalline silicon solar panels
Polycrystalline silicon solar panels use polycrystalline silicon solar cells to arrange photovoltaic modules of different powers in different arrays to meet the electricity demand of different electrical appliances. The manufacturing process of the polycrystalline silicon solar panel is similar to that of the single crystal silicon solar panel, but the photoelectric conversion efficiency of the polycrystalline silicon solar panel is reduced a lot, and its photoelectric conversion efficiency is about 12%.
The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest is 18%. This is the highest photoelectric conversion efficiency of all types of solar panels, but the production cost is so large that it cannot be widely and widely used. To use. Because monocrystalline silicon is generally packaged with tempered glass and waterproof resin, it is sturdy and durable, with a service life of up to 15 years and a maximum of 25 years.
In terms of production cost, it is cheaper than single-crystal silicon solar panels, the materials are simple to manufacture, the power consumption is saved, and the total production cost is low, so it has been developed a lot. In addition, the service life of polycrystalline silicon solar panels is shorter than that of monocrystalline silicon solar panels. In terms of cost performance, monocrystalline silicon solar panels are still slightly better.
