solar raised pavement marker for freeway green in South Africa
There is one part of the solar spike that needs attention, and that is its solar panels. The solar panel directly absorbs the solar energy and converts the light energy into electrical energy, which is the first link in the whole solar road stud working system, and its working efficiency directly determines the quality of the solar road stud. At present, the solar cells commonly used in the industry are monocrystalline silicon panels. This is because monocrystalline silicon solar panels have a high photoelectric conversion rate of about 14%, which can convert solar energy into electrical energy to the greatest extent possible to ensure solar road spikes. Energy supply at work. In addition, solar panels must be high-hardness, wear-resistant circuit boards. If the strength is not enough, it will be crushed and worn by the wheels every day, and it is easy to grind, which will affect the conversion efficiency of solar panels.
