Major loads of a petrol pump comprises of fuel dispensers which generally has a 1 Hp rating and office working loads such as fans, lights, and desktops. As majority of customers comes during the day, it becomes very feasible applying solar and cut electricity costs. Depending on the site and panel selection, applying solar can save 4-5 units per KW in a day.
One such installation was done on a HP Petrol pump in Baseda. (Shiv Filling Center)
Components of this solar set-up:-
Solar MPPT inverter 7.5 KVA/96V Luminous ( 1 nos.)
Solar Panels 330Wp Luminous ( 15 nos.)
Solar Battery 150 Ah ( 8 nos.)
DCDB box ( 1 nos.)
ACDB box ( 1 nos.)
Chemical Earthing ( 1 nos.)
GI structure and Installation
The solar 7.5KVA MPPT inverter has a load capacity of 6 KW and is 30% more efficient than a PWM inverter. It also extract solar energy in rainy and cloudy days as well.
Solar battery has C10 rating which provides 20% more back-up than a C20 rating battery of same capacity.
DCDB and ACDB boxes serves as protection against high electric surges and comprises of MCB’s, SPD’s and Isolator.
Chemical Earthing is required to protect solar panels from damaging during a thunderstorm lightning.
Cost Estimate:-
This set-up costs approx. INR 3,85,000/- and helps save 20-25 units in a day.
