Tech Insights | How to Choose a Solar Street Light Controller? A Comprehensive Comparison of MPPT vs. PWM
In a solar street lighting system, the charge controller is often referred to as the "brain" — it manages the charging of the battery from the solar panel, controls the discharging, and switches the load on and off. It directly determines the lifespan and lighting performance of the entire system. Yet, many installers and end-users face a fundamental question when selecting a controller: MPPT or PWM — which one is right for my project? Today, we provide a clear and practical guide from three perspectives: working principles, application scenarios, and cost-effectiveness.
