The solar street light remote monitoring system solution is widely used for lighting of urban and rural roads, highways, dikes, bridges, parks and scenic areas, industrial areas, city squares, etc. Main components of the system include photovoltaic module, MPPT remote controller, 433M wireless module, concentrator, 433M antenna, GPRS antenna, mobile SIM card, battery and LED light. It is a new solution that applies an efficient MPPT charging method and Internet monitoring of system data to solve outdoor lighting problems. MPPT tracking efficiency is up to 99.9%, significantly improving the energy utilization efficiency of photovoltaic system, which is about 15% to 20% higher than traditional PWM charging and solves energy waste problem due to insufficient charging efficiency. System data is wirelessly transmitted by 433M and GPRS antennas. An internet monitoring system is used to query historical reports. The problem of high maintenance cost of street lighting systems is solved.
