It consists of photovoltaic panels (solar panels) that absorb sunlight, convert it into electrical energy, and store it in batteries to power LED or CFL lamps during nighttime. These lights are widely used in streets, highways, parking lots, and remote areas where grid.

It can be expressed as: Daily Energy Consumption (Wh) = LED Wattage x Hours of Operation. In the example given, the computation would yield: 30 watts x 12 hours = 360 watt-hours per night.
