1. The relationship between the sunshine coefficient and the charging capacity of solar LED street lights.
The sunshine coefficient varies from region to region, with some areas having high sunshine coefficients and others having low sunshine coefficients. The difference in insolation coefficient directly affects the amount of charging of solar panels. In areas with high sunshine coefficient, solar LED street lights will charge more with solar panels of the same power. Conversely, in areas with low insolation coefficients, the amount of charging per day is reduced, so more powerful solar panels are needed.
2. The influence of rainy days on the continuous lighting of solar street lights.
The number of rainy days varies from region to region, with some areas having more rainy days and some areas having fewer rainy days. In order to ensure that the solar street lights continue to be lit on rainy days, it is necessary to choose the appropriate solar lithium battery capacity according to the number of rainy days in the local area. In areas with many rainy days, it is necessary to increase the capacity of solar lithium batteries to ensure that street lights can work normally on rainy days. Conversely, in areas with few rainy days, there is no need to make the battery capacity that large.
Taking Panzhihua and Guizhou Guangxi as examples, the Panzhihua area has fewer rainy days, so the required battery capacity does not need to be that large;However, Guizhou and Guangxi have more rainy days, and the required battery capacity is relatively large.
3. The influence of the temperature difference between the north and the south on the choice of battery.
The difference in temperature between the southern and northern regions is also a factor to consider. The lowest temperature in the southern region in winter will not be lower than minus 10 degrees, so you can use a lower 32V lithium iron phosphate battery. The temperature in the northern region is low in winter, which is not suitable for lithium iron phosphate batteries, and can only use 12V ternary lithium batteries, because ternary lithium batteries have the property of low temperature resistance.
To sum up, it is very important to choose the right solar LED street light system and battery capacity according to factors such as sunshine coefficient, rainy days, and temperature differences in various regions. Only by fully considering these factors can we ensure that solar street lights can work continuously and stably in all regions and contribute to urban lighting.
