Over 50,000 Petrol Pump stations in the country require electricity to run their Petrol Pumps and are paying heavy tariff charges to DISCOMs. Many of the petrol pump owners are also using diesel generators in areas where there are power cuts.
Solar PV Rooftop power plant can be environment friendly and economical viable solution for Petrol Pump owners.
When we look around at various Petrol Pumps in Delhi NCR, Haryana and Uttar Pradesh, most of them have ample shadow free rooftop space available which is unused, which is the first requirement for setting up a Solar Rooftop power plant. Roughly,”10 sq. m” shadow free area is required to install “1 kWp” Solar PV rooftop power plant. Petrol Pump owners can utilize the rooftop space available on their Petrol Pumps to install Solar PV Rooftop power plants and generate their own electricity. With the increasing tariff rates of Electricity from DISCOMs and reducing rates of Solar PV panels, it makes a lots of business sense for going towards solar generation.
Our team surveyed few Petrol Pumps owner in West Delhi. Further we have discussed few queries and concern issues raised by them and few of our observations.
The very first question was on the benefits if they adopt Solar Generation. Few benefits we discussed are as follows:
Reduction in Electricity Bills
Tax benefits of 80% Accelerated Depreciation in first year.
Short Payback period.
Viable Use of Rooftop Space Available
Eco friendly

Next question that arose was “Do we require any storage with Solar PV Power plant? What will happen if there is cloudy or rainy season?”
We told them that in areas where the power cuts or outages are very few (like Delhi), it is advisable to install the Grid-Connected Solar PV Rooftop system without battery backup.
Instead the Petrol Pumps should take Net Metering facility. In this system, Petrol Pumps will take power from the Solar PV Rooftop system when the sunlight is available and when sunlight is not available it will take power from the DISCOM/Grid. On a monthly basis, the number of units generated from the solar solution would be reduced from the number of Units consumed as per the Electricity bill. Only the new Units would be charged to the consumers by the Discoms under the Net metering facility.

Petrol Pumps fall under the category of commercial users and the variable tariff for the same in Delhi is around Rs. 10.83 / kWh. So, a 20 kWp Solar PV Rooftop system will produce approximate 31,000 units of electricity annually which can save roughly around Rs. 3.3 Lac per annum.
We were further told about the safety aspects needed to be followed at the petrol pumps. For example the welding required for mounting the solar panel structures cannot be taken up at the petrol pump. The possible solution could be to take up the soldering of the mounting structures at a faraway place from the petrol pump, and then the welded structure can be placed at the rooftop of the petrol pump.
One of the petrol pumps that we visited had two potential sites for the Solar PV System installation. First one was the Shed of Petrol Pump having shadow free area of approximate 250 sq. m where 25 kWp can be installed. Second one was the roof of the office with shadow free area of approximate 100 sq. m which can have a solar installation of around 10 kWp.
We suggested the petrol pump owner to consider to installing Solar PV rooftop system in phases. In the first phase they can go for 10 kWp system at the office rooftop, and can learn more about the solar energy in the process. Once they themselves can see the benefits of the Solar PV Installation, they can go ahead to the next phase with a 20-25 kWp Solar PV system at petrol pump sheds.
Clearly, there are issues that are specific to the Petrol Pumps. However, none of them are unsurmountable. On the other hand, there are significant benefits and savings that the petrol pumps can take by installing solar.
