Hyderabad: As part of its attempts to adopt energy conservation measures at workplaces, stations and other areas, the South Central Railway (SCR) integrated solar roof with pre-fabricated concrete walls at newly constructed booking office building at Kamareddy Railway Station.
As part of this initiative, the roof of the facility is fully made up of solar panels, which has proven to be economical compared to conventional RCC roof. The roof of the building is a pre-fabricated structure with polycrystalline silicon solar photovoltaic (SVP) panels fitted on mild steel structure instead of constructing conventional RCC structure, SCR officials said.
The average cost per square metre of a pre-fabricated roof is Rs 13,750 whereas the cost per square metre for RCC structure is around Rs 25,000. A total of 18 SVP panels each with a capacity of 320 Wp (Watt peak) totalling to 5.76 kWp (kilo Watt peak) are incorporated as the roof of the building while 5 kWp inverter is made operational for converting solar power into 3-phase AC supply.
Switch gears with necessary protections such as surge protection device and lightning arresters were arranged along with earthing provisions. Approximate energy generation from this structure is around 6,000 electrical units per annum resulting in saving of Rs 60,000.
This concept of prefabricated structure with SPV panels can be constructed within a reasonable time and cost covering more plinth area as compared to regular RCC structures. The roof assembly is lightweight and has the flexibility of dismantling and shifting to some other place, a press release said.
Gajanan Mallya, General Manager, SCR, appreciated the efforts of officers and staff of Hyderabad division for adopting this innovative concept to conserve the energy while promoting a green environment.
