Solar street lights are well known to people. Unlike traditional street lights, they use solar panels as the main source of power.
Solar energy is a new energy source and a renewable resource that aligns well with national conditions. The solar street light system has become widespread in the country.
Solar street light systems are generally small photovoltaic systems. According to World Bank standards, the self-consumption current of the controller in small photovoltaic systems must be less than 1% of the extra working current. Therefore, the design of the controller circuit and the selection of low-power components are crucial.
Solar street lights use integrated operational amplifiers as control circuits. This type of circuit is entirely hardware-based, making it simple, reliable, easy to maintain, and cost-effective, with very low power consumption. The core of this circuit focuses on accurately characterizing the charging and discharging properties of the battery. Reliable components are chosen, combined with an LED-based charging and discharging status indicating circuit, resulting in a functional controller circuit that prevents battery over-discharge and overcharge. The system employs a direct coupling method for charging and discharging control, adapting power based on the characteristics of the LEDs and the battery. During months of insufficient sunlight, the battery’s charge level is generally low, causing the discharging terminal voltage to also be low. This results in smaller load operating current and thus longer operational time for the system. Conversely, when sunlight is abundant, the load operating current and power are higher, leading to brighter illumination.
