The key to the perfect combination of the solar photovoltaic power generation technology and the LED lighting is the same as the DC power, low voltage and can be matched with each other. Therefore, the combination of the two does not need to convert the DC power generated by solar cells into alternating current, thus greatly improving the efficiency of the entire lighting system. At the same time, with the help of the grid technology or the use of storage battery charging and discharging energy, its advantages are more obvious. With the in-depth study of related technologies, LED's luminous efficiency is constantly improving, ultra high brightness LED will come out, it is bound to replace the ordinary lighting electric light source, and a large number of energy conservation and no pollution.
The operating current of the LED is DC, and the operating voltage is low. The solar cell converts light energy into direct current, and the solar cell element can be combined in series and parallel to obtain the actual need. These characteristics coincided with the led to match, a combination of both will get very high energy utilization rate, high safety and reliability, to achieve energy saving, environmental protection, safety, high efficiency lighting system, realize the perfect combination.
