World’s Largest Single Rooftop Solar PV Plant commissioned in Punjab
Mumbai: L&T Construction, India's largest solar EPC company, has recently commissioned the world's largest Solar Photovoltaic Plant of 7.52 MWp capacity on a single roof at Amritsar in Punjab.
The energy generated from this plant is being fed to the local grid through a power purchase agreement (PPA) signed with the state distribution company under the New and Renewable Sources of Energy (NRSE) Policy.
For this project, L&T employed multi-crystalline module technology and central inverters to optimize efficiency. More than 30,000 panels were erected on the rooftop of the shed spread over 94,000 sq.m area.
Since for this project, the rooftop modules had to be erected on fragile asbestos roof sheets, L&T's project engineers designed and implemented an appropriate and customized Balance of System. Without stressing the existing roof sheets, the entire load of the PV modules and BoS were transferred to the roof of the space frame members of the top and middle chords. Lightweight aluminium structures were used for mounting the modules and water proofing techniques were used to avoid leakages.
L&T along with the customer came up with an innovative idea of erecting a permanent network of aluminium walkways on top of the roof sheets to create a safe working environment for execution, operation and maintenance purposes.
Commenting on the achievement, S. N. Subrahmanyan, Senior Executive Vice President (Infrastructure and Construction), L&T said, "This is for us, at L&T Construction, a significant step towards establishing our credentials as the country's largest and leading Solar EPC Company. It is also extremely creditable that this state-of-the-art solar power plant has already exceeded the estimated performance."
L&T is a major Indian multinational in technology, engineering, construction, manufacturing and financial services, with global operations. It is India's largest Solar EPC Company with over 400 MW (including commissioned and under-construction) solar PV and concentrated solar thermal power projects.
