Solar street lamps working principle in detail
Principle: system working principle of the system is simple, using the photovoltaic effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the intensity of illumination is gradually reduced to about 10 lux, solar panels open circuit voltage is 4.
Around 5 v, charge and discharge controller to detect the voltage value of the action, the battery to discharge lamp holder.
After eight hours of battery discharge, charge and discharge controller action, battery discharge end.
Main function is to protect the storage battery charging and discharging controller. Solar power systems: how it works: 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. the advantages of solar street light: 1, LED solar street lamps using solar photovoltaic battery power, new energy, solar energy as a kind of green environmental protection & other;
Throughout limitless reserve, using them all &; Make full use of solar energy resources, to relieve the tense situation of conventional energy have positive significance.2, solar street lamp manufacturer to introduce solar street lamp installation is simple, convenient, need not like ordinary street lamp do laying cable, such as a large number of foundation engineering, only need to have a fixed base, all the lines and control parts are placed in the lamp, to form a whole. 3, the operation of the solar street light maintenance cost is low.
Using solar power, solar street lamp in addition to the rainy day into a mains power supply will produce a small number of electricity cost, operation cost is almost zero.
The whole system running are automatic control, without human intervention, almost do not produce maintenance costs.
As we have known for quite some time, the success of SRS in the future will depend greatly on our ability to strike a balance between valuable human insight and interaction with technology.
