How to determine the power of solar panels solar panels that the number of w
the controller of the waterproof, the controller is generally installed in the lampshade, the battery box, the general will not water, but in the actual project case the controller terminal for the rain along the cable into the controller caused by short circuit. So the construction should pay attention to the internal cable bent into a "U" font and solid type, external connection "U" type, so that rain can not fall into the controller caused by short circuit, the other can also be inside and outside the interface coating The
the choice of the controller is often overlooked by the engineering staff of a problem, the quality of the controller is poor, 12V / 10A controller market price range, although the value of the entire street system, the smallest part, but it Is a very important part. Damage to the controller directly affect the life of the solar parts and the entire system procurement costs, one: should choose a lower power controller, the controller 24 hours without interruption, such as its own power part of the power, the best choice for power consumption 1 mA (MA) below the controller. Second, to select the high efficiency of the controller,
battery life should also be considered in the entire street lamp system applications, the general battery warranty for three years or five years, the general power storage after six months there will be dissatisfied with the situation, some of the actual charge rate may drop to 50% , Which will affect the continuous rainy days of the night to choose a better battery is particularly important.
At present, one of the most important aspects of the control of solar power applications is the price, with a two-way solar street lights, for example, as the 6 downstream areas effective lighting 4.5h / day, 7 hours per night discharge, increase the battery 20% of the amount of reserve calculation) the battery board will need about 160W, according to the cost of the battery will be 4800 yuan, plus 180AH about the cost of the battery is also around 1800, the whole one-time investment in street lights caused by solar street lights The main bottlenecks in the application area.
The power of the solar street light depends on the width of the road and the surrounding environment, depending on the width of the road, the line distance depends on the power of the light source and the secondary light distribution of the lamp. With the growing shortage of traditional energy, solar energy applications will be more and more widely, especially in the field of solar power in a few years time has developed industry.
