![]() Therefore, monocrystalline silicon solar cells with better cost performance should be used in the design.ĭue to the difference between the total annual solar radiation and the average peak sunshine hours in various regions on the earth, the design of solar lawn lamps is related to the geographic location of the lamp. The performance of the solar cell directly determines the energy conversion efficiency and the stability of the output voltage, and also directly determines the performance of the supercapacitor solar lawn lamp. Solar cells are semiconductor devices that convert sunlight energy into electrical energy based on the principle of the photovoltaic effect of semiconductor PN junctions and are the core devices of supercapacitor solar lawn lights. Since the lawn lamp not only has a decorative function but also has a certain lighting function, you can choose 8 LEDs to use. Therefore, considering the reliability, cost performance, color temperature and luminous efficiency, a super bright LED with a rated voltage of 3.3 V and an operating current of 6 mA can be selected as the light source in the design. In addition, the LED is powered by a low-voltage direct current, its light source control cost is low, the brightness can be adjusted, and it can be switched on and off frequently, and it will not adversely affect the performance of the LED. The current LED life can reach more than 100,000h, and the working voltage is low, which is very suitable for solar lawn lights. As a kind of fast charging, long life, green, and environmentally friendly energy storage components, supercapacitors have brought new vitality to the development of solar products.Īs LED technology has achieved a key breakthrough, the performance-price ratio has also been greatly improved. ![]() Because the battery life is short and environmentally friendly, this article introduces a design method based on supercapacitor solar lawn lights. Even on cloudy days, this solar generator (solar panel) can also collect and store solar energy. ![]() It can independently convert solar energy into electric energy, and convert electric energy into heat energy for lighting and decoration, without the need for wire transmission. The solar lawn light is an independent solar power system. ![]()
