One of the world’s largest on-site solar power plants came online this week in India’s Punjab state.

Inaugurated on Tuesday by the state’s chief minister Parkash Singh Badal, the 11.5 MW plant will power the headquarters of the Radha Soami Satsang Beas spiritual sect in the town of Beas, 45 km from the northwestern city of Amritsar.

The plant’s 17 ha of solar panels were installed on a single rooftop by the Radha Soami Satsang Beas Educational and Environmental Society with technical collaboration from the Punjab Energy Development Agency (PEDA).

The project is expected to generate sufficient power for 8000 households.

PEDA director Balour Singh said installation on a shed used to house the sect’s followers took around six months to complete.  

The Beas campus already featured 8 MW of solar capacity installed on seven additional roofs. The new array brings the complex’s total capacity to 19.5 MW across 33 ha.

The 11.5 MW array is being reported as the world’s largest single-rooftop on-site solar power array.
