Solar street lamps and energy saving1

Based energy as the earth's resources increasingly poor, the investment cost of the surging, all kinds of safety and pollution hidden danger is everywhere, the solar energy as a & other; As ever, an inexhaustible & quot; Safety, environmental protection, new energy more and more attention. At the same time, also with the development and progress of solar photovoltaic technology, solar lighting products in the double advantage of environmental protection and energy saving, solar street light, solar garden light, solar lawn lamp and so on applications has gradually formed the scale, solar power development has gradually perfect in the field of street lighting.

and talk about why to energy saving, solar street lamps have to tell me about the working principle of solar street light: during the day, under the condition of light, solar battery components produce certain electromotive force, through component of series-parallel solar cell phalanx formation, makes the square voltage to achieve the requirement of the system input voltage. Again for battery charging, the charging and discharging controller will be used by light conversion of electrical energy storage. Evening, battery to provide inverter input power, through the role of the inverter, to convert direct current (dc) to 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 and 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.
