With the increasing demand for solar street lights, they can be used in various locations and come in different design styles and appearances. The different appearances and configurations of solar systems determine the price of solar street lights. Currently, they have promising prospects in the lighting market. Do you know why there is no unified standard for the configuration of solar street lights? Below, the editor of Century Sunshine Lighting will provide a detailed explanation on this topic.
Reasons for the lack of a unified standard for solar street light configurations:
1. The number of rainy days varies across regions.
In areas with many rainy days, to ensure the solar street lights remain lit during prolonged cloudy weather, the capacity of the solar lithium battery must be increased. Conversely, in regions with fewer rainy days, the battery capacity does not need to be as large. For example, in Panzhihua, where rainy days are few, the required battery capacity is not as significant compared to regions like Guizhou and Guangxi, which experience more rainy days.
2. The solar radiation coefficient varies by region.
In regions with a high solar radiation coefficient, solar LED street lights charge more efficiently with the same power solar panels. However, in areas with a low solar radiation coefficient, the daily charging amount is less, requiring larger solar panel power compared to regions with higher coefficients.
3. Temperature differences between northern and southern regions.
In southern regions, winter temperatures generally do not drop below -10 degrees Celsius, allowing for the use of more cost-effective 3.2V lithium iron phosphate batteries. In contrast, northern regions, where winter temperatures are lower, are not suitable for lithium iron phosphate batteries and can only use 12V ternary lithium batteries due to their low-temperature resistance properties.
The aforementioned reasons for the lack of a unified standard for solar street light configurations provide insights into this issue. From the information provided, we can understand that solar street lights cannot adhere to a single standard across all regions. This results in varying prices for solar street lights in different areas, as manufacturers configure different setups based on regional needs, making it impossible to establish a universal pricing standard.
