What is a solar lamp?

Solar energy lamp system principle of the system working principle is simple, using the principle of photovoltaic solar cells made of solar panels during the day to receive solar radiation and translated into electricity output, after filling put some controller in the storage battery, often at night when the light is gradually reduced to around 101 ux, solar panels open circuit voltage is 4. Around 5 v, charge and discharge controller to detect the voltage value after the movement, storage battery for ACTS of discharge. After the death of battery discharge 8 jokes, charging controller action, battery discharge end. Main function is to protect the storage battery charging and discharging controller. Principle of work during the day, under the condition of light, solar energy battery components produce certain electromotive force, parallel with the component in series solar cell phalanx formation, make the square voltage to achieve the requirement of the system input voltage. In for battery charging, the charging and discharging controller by light conversion of electrical energy storage. Evening, battery to provide inverter input power, through the role of the inverter, the direct current into alternating current (ac), to the power distribution cabinet, the distribution function of switching power supply. Battery discharge conditions by the controller to control, to ensure the normal use of the battery. Photovoltaic power station system should also be limited load protection box of lightning protection devices, in order to protect the loading operation of the system equipment and from lightning strikes, protect the safety of the system equipment use. Solar energy lamp the advantages of using solar photovoltaic cells, solar energy as a new energy of green, white, full solar energy resources to relieve the tense situation of conventional energy have positive significance. Solar energy lamp installation is simple, convenient, need not to ordinary street lamp do laying cable, such as a large number of foundation engineering, need only a fixed base, all circuits and control part of the box in the lamp, to form a whole. The operation of the solar street lights maintenance cost is low. Using solar power, solar street lamps in addition to the rainy day is converted into a pilot power supply wire to produce a small number of electricity cost, operation cost is almost zero. The whole system for automatic control, without human intervention, almost do not produce maintenance costs.
