Petrol pumps are often situated in outskirts of the main cities where powercuts are common. Pumps usually consume a lot of electricity as they have to function 24 hours. Petrol pumps in India often rely on diesel generators which are expensive and do not provide instant back-up. A 10kva generator may take 1.5 liters of petrol per hour! On the other hand, solar power system comes at half the cost as it provides free solar electricity for 2 decades. Most petrol pumps, who install solar, recover the full cost of solar installation in less than 3 years!
Off-grid solar package is very popular among petrol pump owners in India. The package consists of Solar PCU, batteries and Solar panels. Batteries store the solar energy generated by PV panels and provide 24 x7 backup to petrol pumps.
This is the most-suited solar solution for petrol pumps that are situated away from the main cities and face frequent powercuts because solar energy can be stored in batteries for later use. Off-grid solar package for petrol pumps consists of solar panels, battery bank, and Solar PCU which functions both as an inverter and charge controller.
If petrol pumps already have inverter and battery bank, then they can choose to make a solar system out of it by installing solar panels and solar charge controller. While solar panels make solar energy, the charge controller ensures that solar energy is utilized efficiently to charge batteries.
This could be a revolutionary, energy-efficient and cost-effective solution for all petrol pumps. DC system consists of solar panels, batteries and lights & fans that can run on DC. If a petrol pump installs Solar DC System, then it doesn’t have to rely on grid for running fans and lights.
Grid-tie solar installation could be a good choice for petrol pumps situated in cities that do not face many powercuts. This is a battery-less system that consists of grid-tie inverter and solar panels. Surplus solar electricity generated can be fed back into grid through grid-tie solar.
