Method for improving charging efficiency of solar street lamps
Nowadays, solar street lamps have achieved comprehensive development of rural road construction with its operating cost, long service life, safety and stability, and green energy conservation. In order to better realize the rapid development of solar street lighting in road construction, how can we Better improve the charging efficiency of solar street light panels?
The charging efficiency of solar street lamps mainly includes two aspects, namely the conversion efficiency of solar panels and the secondary conversion efficiency. The conversion efficiency of solar panels refers to the efficiency of conversion of light energy into electrical energy; and the secondary conversion efficiency refers to the efficiency of storage of light energy on a storage battery after being converted into electrical energy.
In order to improve the secondary charging efficiency of the solar street lamp, the capacity of the battery in the current solar street lamp configuration process is generally 1.2 times that of the solar street lamp system to meet the night lighting demand. Moreover, in order to ensure the service life of the solar street lamp controller, the entire control circuit should also be protected during the charging process of the solar street lamp.
In order to better realize the rapid development of solar street lamps in the current road lighting, for the development of solar street lamp technology, only the secondary conversion rate of solar street lamps during daytime charging can be realized to realize the rapid application of solar street lamps in the future. development of.
In order to ensure that the solar street light can achieve good work, the most important thing in the street light configuration is to look at the street light configuration in the rainy day. Because the solar street lights can't receive the light in the rainy days, it is very important to make the street lights configuration in the rainy days to ensure the long-term stability of the solar street lights.
When solar street lights can be used in normal rainy days, the first thing to ensure is the conversion rate of solar panels. In order to prevent the solar street lamp from being powered off during rainy days, the solar panel must increase the conversion rate during the street lamp configuration to provide sufficient energy for the solar street lighting.
The second is to do a good job of battery capacity configuration, to ensure that solar street lights have sufficient storage skills to achieve high conversion rate with solar panels.
Finally, the street lamp system configuration is reduced to reduce the internal discharge loss of the system to save the energy consumption of the street lamp itself.
