Why is there no unified standard for solar street lamp configuration?
With the progress of photovoltaic technology, solar energy is used more and more widely, and many rural street lamps also use solar energy. Solar LED street lamps have been widely used In rural areas. However, the price of solar street lamps on the market is uneven, mainly because there is no unified standard for their configuration. Some configurations are high, since But the price is high. Some configurations are low, and the natural price is low. So why is there no unified standard for the configuration of solar street lamps?
1、 The sunshine coefficient is different in each region
In some areas with high sunshine coefficient, solar panels with the same power are used, and the solar LED street lamps in this area have more charging capacity. And sunshine in some areas If the coefficient is low, it will charge less every day. Therefore, compared with areas with high sunshine coefficient, the power of solar panels will be greater.
2、 Rainy days vary from region to region
In some areas, there are many rainy days, so in order to ensure that the solar street lamps are on continuously, the capacity of solar lithium battery must be increased. And some land There are few rainy days in the area, so the lithium battery capacity does not need to be so large. Just like Panzhihua and Guizhou and Guangxi, Panzhihua has few rainy days, so what does it need The required battery capacity does not need to be so large, while Guizhou and Guangxi are the opposite.
3、 Temperature difference between North and South
The lowest temperature in winter in the South will not be minus 10 degrees, so a lower price 3.2V lithium iron phosphate battery can be used, while the temperature in winter in the north is low, it is not suitable to use lithium iron phosphate battery. Only 12V ternary lithium battery can be used because ternary lithium battery has the property of low temperature resistance.
Therefore, from the above three points of view, solar street lamps can not achieve a unified standard in every region. This also resulted in procurement in each region The price of solar street lamps is different because solar street lamp manufacturers match different configurations according to different regions, so there is no single price of solar street lamps Uniform standards.
