The battery is another crucial component of a solar-powered traffic light system, including street lights, as it stores the electricity generated by the solar panel for use during times of low sunlight or at night. Batteries used in these systems are typically deep-cycle batteries as they can discharge up to 80% without damaging the battery’s lifespan.

When selecting a battery for a traffic light system, it’s essential to consider its capacity and voltage rating. Capacity refers to how much charge the battery can hold while voltage rating refers to how much power it can deliver at once. A higher capacity battery is suitable for areas with low sunlight levels while a higher voltage rating is necessary for areas with high energy consumption.

LED lights

LED lights are energy-efficient bulbs that consume less power than traditional incandescent bulbs and provide bright and clear illumination. They have become popular in recent years due to their long lifespan and durability, making them ideal for improving traffic flow on roads and highways.

When selecting LED lights for a traffic light system, it’s important to consider their wattage and color. Higher wattage LED lights are suitable for areas with high traffic while lower wattage lights are sufficient for low traffic areas. The color of the LED light determines its visibility, and red, green, and yellow are the most commonly used colors in traffic lights.
