India’s Punjab state has had few takers for its on-site solar power initiative in the city of Jalandhar, the Hindustan Times reports.

Jalandhar is one of India’s oldest cities and has recently seen an explosion of urbanization, industry and commerce.

Under a scheme put in place in 2014 by the Punjab Energy Development Agency (PEDA), though, only three industrial sites in the city have installed rooftop solar systems, the paper said.

The scheme supports installations from 1 kWp to 1 MWp for self-consumption and/or net metering.  

Supinder Singh, PEDA district manager, told the newspaper that a lack of government subsidies for industrial solar systems is the problem, while 30% of the costs of such systems are subsidized for residential customers.

However, he noted that of the 217 applications to install residential solar systems accepted by PEDA in a single year, only 18 households in Jalandhar actually installed the systems.

According to Singh, the city of Ludhiana – Punjab’s largest city and also an industrial centre – has had more success.

“The industrialists there look to the long-term profit since after a few years the solar power cell gives you the pay back assurance of one-time investment,” he was quoted as saying.

Punjab is host to one of the world’s largest rooftop solar systems, which came online earlier this month. The 11.5 MW plant will power the headquarters of the Radha Soami Satsang Beas spiritual sect in the town of Beas, and features 17 ha of solar panels installed on a single roof.
