With the development of photovoltaic technology, the use of solar energy is becoming increasingly widespread, and many rural street lights also use solar energy. Solar LED street lights have been widely used in rural areas. However, the prices of solar street lights in the market are uneven, mainly because there is no unified standard for their configuration. Some configurations are high, so naturally the price is high. Some configurations have lower natural prices. So why is there no unified standard for the configuration of solar street lights?
1、 The sunshine coefficient varies in different regions
In some areas, the sunshine coefficient is high, so solar panels of the same power are used, and the solar LED street lights in this area have a relatively large charging capacity. In some regions, the solar coefficient is low, so the daily charging amount will decrease. Therefore, compared to areas with high solar energy coefficients, the power of the solar panels used will be higher.
2、 The number of rainy days varies in different regions
In some areas, there are many cloudy and rainy days, so to ensure that solar street lights continue to light up during rainy days, it is necessary to increase the capacity of solar lithium batteries. In some areas, there are fewer rainy days, so the capacity of lithium batteries does not need to be so large. Just like in Panzhihua and the Guizhou Guangxi region, where Panzhihua has fewer rainy days, it does not require such a large battery capacity, while the opposite is true in the Guizhou Guangxi region.
3、 The temperature difference between the north and south
In winter, the low temperature in the southern region will not be lower than minus 10 degrees Celsius, so cheaper 3.2V lithium iron phosphate batteries can be used, while in the northern region, the winter temperature is lower, so lithium batteries are not suitable. Iron phosphate batteries. Only 12V ternary lithium batteries can be used. Because ternary lithium batteries have the advantage of low temperature resistance.
Therefore, from the above three aspects, solar street lights cannot meet a unified standard in every region. This also leads to different prices for solar street lights purchased in each region. This is because solar street light manufacturers will match different configurations according to different regions, so there is no unified standard for the price of solar street lights.
