In the past, we use the street lights need to connect the power to work properly, and the installation is complicated, consuming manpower, material and financial resources. Now, the emergence of solar street lamp is a good solution to some of the shortcomings of the past street lamps, with environmental protection, energy saving, high efficiency, etc., then there may be some people who have doubts that solar street lights require external power source? Euler Energy ‘s technicians will answer that question for everyone :
Solar street light is a new type of energy saving and environmental protection products. It is mainly through the absorption of sunlight to be converted into electrical energy and stored in the battery, the battery supplies power for light source, therefore, it does not require external power source, the solar street light system is an independent power generation system.
The transform principle of solar street light :
Under the light conditions during the day , the solar cell module generates a certain electromotive force. The solar cell array is formed by series and parallel connection of the modules, so that the square matrix voltage meets the requirements of the system input voltage. And then the charge-discharge controller will be converted from light energy and stored the energy in the battery. In the evening, the battery pack provides input power to the inverter. Through the function of the inverter, the DC power is converted into AC power and delivered to the power distribution cabinet, which is powered by the switching function of the power distribution cabinet. The discharge condition of the battery group is controlled by the controller to ensure the normal use of the battery.
Solar street light powered by a crystalline silicon solar cell , maintenance-free valve-regulated sealed battery (gel battery) storage of electricity, without laying cables, no AC power supply, does not generate electricity; DC power supply, control; with good stability and long life , High luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical advantages.
