Whether it is a solar street light, lantern or wall light, a solar lighting system follows the same process. A small solar lighting system is ideally suited for a house of 4 people, lighting 2-4 lamps for up to 4 hours daily. Such a solar home lighting solution can help save approximately Rs 7200 worth of kerosene while saving carbon emissions equivalent of burning approximately 240 litres of kerosene.
When the sun’s radiation falls on a solar photovoltaic (PV) panel, current is generated.
The current produced from the PV panels is controlled and regulated by an inbuilt/standalone charge controller/inverter. The inverter sends the current to charge the battery.
When the connected appliances are switched on, the charge controller/inverter also helps regulate the current from the battery, sending it to the output appliance to provide light and energy.
