With economic development, population growth and social improvement of living standards, the future world energy consumption will continue to grow, the total consumption of fossil fuels in the world one day will reach the limit. The development and utilization of renewable energy and green energy in order to achieve sustainable development of mankind must take measures. From the energy supply of many factors to consider, solar green energy is undoubtedly the ideal of sustainable development strategy. With the continuous development of the city, the rapid population increase, per capita number of vehicles increases, more and more severe parking problems. The development of parking lot gradually toward the underground space. However, the underground car park lighting gave the community has added a new worry. To this end, an underground lighting system is an urgent requirement of the times. This design uses LED lighting as the lighting system, solar photovoltaic power generation and electricity interact to provide a power supply for LED lamps powered. Use of energy saving lamps to reduce energy waste, the use of solar power generation and distribution, to reduce atmospheric pollution caused by the thermal power and other issues. This design uses a microcontroller AT89S51 as the main control unit, focused on the design of a solar power system maximum power point tracking control circuit design. And by collecting solar power system battery and the voltage across
