What is Solar Light?

Solar Lights:
System Principle: The system works simply, using principles of photovoltaic effect of solar cells made from solar panels during the day to receive solar radiation and convert to electricity output, through the charge-discharge controller is stored in batteries at night when the illumination gradually reduced to 10lux around open circuit voltage of solar panels around 4.5V, charge-discharge controller, the voltage value detected after the action, battery discharge of the lamp. 8 hours after the discharge of batteries, charge-discharge controller movements, the end of battery discharge. Charge and discharge controller's main role is to protect the battery.
Solar Power System:
How it works:
During the day, in the light conditions, the solar cell components produce a certain electromotive force, through the formation of the component series-parallel solar cell matrix, making square voltage system input voltage demands. And through the charge and discharge controller to recharge batteries, will be converted from light energy stored up. The evening, battery for the inverter to provide input through the inverter the role of the direct current into alternating current, transmission to the distribution cabinets, distribution cabinets from the role of switching power supply. The discharge of batteries controlled by a controller to ensure the normal use of battery. PV power plant system should also be limited load protection and lightning protection devices to protect the system equipment from lightning overload operation and to maintain the safe use of system equipment.
Solar street lamp advantages: Yi Jia Photoelectric
1, solar street lamp provide electricity using solar photovoltaic cells, solar energy as a green new energy, "inexhaustible, bottomless." Make full use of solar energy resources, ease the tense situation of conventional energy sources are of positive significance.
2, solar street lamp installation simple, convenient, no need to do, as ordinary street a lot of basic engineering the laying of cables, etc., just to have a fixed base, all the lines and control part are placed in the lighthouse, forming a whole.
3, solar street lamp operation and maintenance cost is low. Solar lights use solar power, in addition to rainy days converted to electricity supply will produce a small part of the electricity costs, operating costs almost zero. The entire system is running are automatic control, without human intervention, almost no maintenance costs.
