Today's society is the society of energy, with the increasing shortage of traditional energy, the application of solar energy has been more and more extensive, especially in the field of power generation in a few short years has developed into a mature sunrise industry, solar street light also walked in the socialist "bright road". How much do you know about it?

Currently one of the most important part of restricting the application of solar power is the price, with a light dual solar street light, for example, two road load sharing is 60 watt (conservative estimate), the panels will need to about 160 w, 40 yuan per watt calculation, the cost of the panels will be 6400 yuan, plus 180 ah battery costs are at around 2000, The one-time input cost of the whole street lamp is much higher than that of the electric street lamp. It can be said that the price is the main bottleneck in the field of solar street lamp application.

The service life of the battery is also a pharmaceutical factor that must be considered for street lamps. Most battery warranty for three years or five years, but the general battery in one year or even half a year later will be in charge of discontent, some actual charge rate may fall to about 50%, this will affect street lamp in continuous rainy period normal lighting at night, so choose a good battery is especially important for a street lamp.

The choice of the controller is often ignored by the engineering company is a problem, so the quality of the controller is not uniform, the market price of 12V/10A controller is 100-200 yuan, although it is the smallest part of the value of the whole street light system, but it is a very important link, can not be ignored. In addition, the waterproof of the controller also needs to be paid attention to together, the controller is generally installed in the lamp shade, battery box, generally will not water, but in the actual engineering case, the connection line of the controller is often short because of rain along the connection line into the controller. Therefore, during construction, attention should be paid to bending the internal connection line into a "U" shape and fixing, and the external connection line can also be fixed as a "U" shape, so that the rain can not be poured into the controller is difficult to cause short circuit.
