1, solar panels:Solar panels are the core of solar street lights, solar lighting is the highest part of the value. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store up. In many solar cells in the more common and more practical monocrystalline silicon solar cells, polysilicon solar cells and amorphous silicon solar cells and other three. In the sunny sunshine good sun and the east of the region, the use of polysilicon solar cells as well, because the polysilicon solar cell production process is relatively simple, the price is lower than the single crystal. In the rainy days are more, the sun is not very adequate in the southern region, the use of monocrystalline silicon solar cells as well, because the monocrystalline silicon solar cell performance parameters are relatively stable. Amorphous silicon solar cells in the case of outdoor sun is not good, because the amorphous silicon solar cells on the sun light conditions are relatively low. 2, solar controllerRegardless of the size of the solar fixture, a well-behaved charge-discharge controller is essential. In order to extend the life of the battery, it must be its charge and discharge conditions to be limited to prevent the battery overcharge and deep charge. In the larger temperature difference, the qualified controller should also have the temperature compensation function. At the same time solar controller should have both street lamp control function, with light control, time control function, and should have a night automatically cut off the load function, to facilitate rainy days to extend the street lamp working hours. 3, the batteryAs the input power of solar photovoltaic power generation system is extremely unstable, it is generally necessary to configure the battery system to work. General lead-acid batteries, Ni-Cd batteries, Ni-H batteries. The choice of battery capacity generally follow the following principles: first in the night to meet the premise of lighting, the daytime solar cell components as much as possible to store energy, but also to be able to store to meet the continuous rainy night lighting needs. Battery capacity is too small to meet the needs of night lighting, battery is too large, on the one hand the battery is always in a state of loss, affecting battery life, while causing waste. The battery should be matched with the solar cell, electricity load (street lamp). A simple method can be used to determine the relationship between them. Solar cell power must be more than 4 times higher than the load power, the system can work properly. Solar cell voltage to exceed the battery operating voltage of 20 to 30%, in order to ensure that the battery is normally negatively charged. Battery capacity must be more than 6 times the load daily consumption is appropriate
