Solar rooftop plant commissioned at Delhi Metro's ITO station

Solar power solutions provider Rays Power Experts on Friday said it has successfully installed a 10 kWp (kilowatts peak) solar power system at Delhi Metro's ITO station in two days, making it the fastest installation of a solar photovoltaic (PV) system in an underground station in India.

The ITO station was inaugurated last week, with trains being flagged off by Urban Development Minister M. Venkaiah Naidu and Delhi Chief Minister Arvind Kejriwal.

Solar electricity systems are given a rating in kilowatts peak, the rate at which it generates energy at peak performance for example at noon on a sunny day (kWp). Each kWp should generate around 800 to 850 kilowatt hours (kwh) of electricity per year if unshaded.

In April, Rays Power won a contract from Delhi Metro for setting up 7 MW solar rooftop photovoltaic plants on selected stations and sites.

The company said it is a tariff-based project at a consistent tariff of Rs.6.248 per unit for a duration of 25 years.

"Rays Power Experts is completely debt free where all capital is raised from company's internal accruals and it is fully equity based," director Rahul Gupta said in a release here on the occasion.
