Abstract
In this work, the smart solar-powered street light system has been designed and implemented in the laboratory. Optimal sized Lithium-ion battery bank is designed and connected with the street light system to fulfill the objective of efficient utilization of available solar energy. The smart control system is designed to protect the storage system from overcharging and deep discharge conditions. The resonant switched capacitor cell balancer circuit is used to equalize the voltages of series-connected cells in a battery bank during the charging and discharging process. A cost-effective LDR sensor is used to make the decisions based on the solar irradiance level and voltage state of the battery bank. For the maximum utilization of solar power, the MPPT is equipped with the proposed system. To analyze the performance of the proposed system, an 80 W of LED street light has been utilized with 230W of PV panel. The obtained experimental results illustrated that the proposed system is able to store the adequate amount of solar power for the street light during the low irradiance condition.
