Shanxi Zezhou new rural street

Shanxi Zezhou new rural street lighting system works: The system works is simple, utilizing the principle of photovoltaic effect solar cell made during the day solar panels to receive solar radiation into electrical energy output, after charge-discharge controller is stored in batteries, night when the illumination gradually reduced to about 10lux, solar panels open circuit voltage of about 4.5V, charge and discharge controller detects the voltage value after the operation, the battery to discharge lamp. After eight hours of battery discharge, charge and discharge controller action, the battery discharge end. Charge controller's main role is to protect the battery. Solar power system: How it works: During the day, in the light conditions, solar modules produce a certain amount of force, the formation of the solar cell matrix by series-parallel assembly, making the square voltage to the system input voltage. Through the charge controller to charge the battery, it will be converted from light energy stored up energy. In the evening, the battery pack provides power to the inverter input, through the action of the inverter, the direct current into alternating current supplied to the power distribution cabinet, distribution cabinet by the switching action of the power supply. Discharge conditions of the battery pack is controlled by the controller to ensure that the normal use of the battery. PV power plant system also limited load protection and lightning protection device to protect the system equipment from lightning overload operation and maintenance of safety equipment to use the system. Advantages of solar lights: 1, solar lights use solar photovoltaic cells provide electricity, solar energy as a new green energy, "inexhaustible, inexhaustible." Make full use of solar energy resources, to ease the tense situation of conventional energy sources has a positive meaning. 2, solar street light installation is simple, convenient, without the need to do a lot of basic cabling and other projects like ordinary street, just to have a fixed base, all the lines and control parts are placed in the lighthouse form a whole. 3, solar street operation and maintenance cost is low. Solar-powered solar street lights, except rainy days converted into electricity supply will have a small part of the electricity costs, running costs almost zero. The whole system are automatically controlled, without human intervention, almost no maintenance costs.
