Abstract :
With the motivation of high efficiency, energy saving and environmental protection, a solar LED lighting system was designed. The system implemented maximum power point tracking technology (MPPT) and precise three-section storage battery charging by charging control, which improves the utilization ratio and lifetime of solar cell, enhancing the energy conversion efficiency. The use of LED lighting and the last half-night´s half-power output lead to highly luminous efficiency and low power consumption. The system control is easy to realize and has high reliability, which makes LED lighting system satisfy functionality requirement and realize maximum energy saving.
