1. Improve the conversion efficiency of solar panels. Choose solar panels with higher conversion efficiency per unit area, and increase the irradiation area of solar panels, so that the power of solar panels can be increased, thus prolonging the working time of solar lights.
2. Increase battery capacity. Due to the uncontrollability of the weather, the solar power supply is not particularly stable, so it is necessary to increase the capacity of the battery, so that the continuous output of electricity, solar lights will work longer.
3. Develop more cost-effective and sustainable solar lighting fixtures. Alternatively, intelligent systems can be used to determine the weather conditions and rationally plan the discharge power.
