Solar street lights are affected by the local solar ultraviolet intensity, which corresponds to how much sunlight is available in a given area. The intensity of ultraviolet rays significantly impacts how much solar energy the solar cells can absorb, directly influencing the daily power generation of solar panels. For instance, there is a considerable difference in ultraviolet intensity between regions like Yunnan and Heilongjiang.
The daily sunlight duration is measured in hours, indicating the effective light exposure each day. This duration directly relates to how long the solar panels can charge the batteries every day. The national average sunlight duration is approximately 3.5 hours. For example, Yunnan enjoys significantly longer sunlight hours compared to Heilongjiang. The average number of continuous rainy days in the local area also affects how solar street lights are designed.
This knowledge helps in the design of solar street lights to ensure they remain operational even after several consecutive rainy days. When calculating the configuration of solar street lights, it’s critical to consider local weather conditions. For instance, in Suqian, Jiangsu, where it rains for about 5 days straight, the solar street lights need to be designed to function normally under such conditions.
Local annual temperature affects the discharge rate and lifespan of the solar street light batteries. Colder temperatures lead to reduced battery discharge capacity. For example, in northeast regions, larger batteries are required to ensure the longevity of the solar street lights. Typically, during winter in northern areas, battery discharge may only reach 70% of the summer capacity, and prolonged low discharge usage can significantly shorten the battery’s life.
The height of the light pole for solar street lights is also an important factor. A taller pole means the light source is positioned further from the ground, which increases the required brightness of the light source. Higher brightness typically results in increased power consumption, necessitating adjustments to the overall configuration of the street lights.
The daily illumination duration, or how many hours lights are on at night, directly influences electricity consumption. Longer illumination times lead to increased power requirements, thus necessitating larger solar panels and batteries. For instance, a configuration designed for 8 hours of illumination each night will be more substantial than a setup for only 6 hours. Additionally, the surrounding environment, such as tall trees or buildings that can obstruct sunlight on the solar panels, requires further adjustments to the configuration.
