Solar streetlights are effective and efficient light sources, in which power is fed with the help of Photo-Voltaic panels.
The solar streetlights comprise of solar cells which absorb the solar energy, during daytime. The photovoltaic cells convert solar energy into electrical energy, which is then stored in the battery.
During the night-time, the lamp starts automatically (with the help of a dark detecting sensor) and it consumes the electricity from the battery. During the daytime, the battery gets recharged and the process keeps on repeating, every day.
Benefits of solar street light–
1. Pollution-free lighting
2. No external wires hanging, thus safer (in case of natural calamities and severe rains)
3. Easy to carry and can be accessed remotely (preventive real-time monitoring can be done)
4. Very less maintenance, needed
5. Thus, sizeable expenditure is only faced once (during installations)
On-grid solar power system is a solar power generation system where it is connected to the utility grid. The electricity produced by the system is routed to the grid from where it is used to run the various appliances.
It works independent of the grid. Most home appliances such as Fans, TV, Cooler, AC, Water Pump etc. can work through this system. For instance, a 1 kW off grid solar system is sufficient for a 2-4 BHK house. But if you also want to run 1HP Water Pump in your home you could use a 3 kW off grid solar system.
