In a blow to the solar thermal power industry, the Haryana government has withdrawn its policy mandating buildings in areas over 500 sqyd to install thermal solar water heaters. The renewable energy department’s decision has come as a major setback for manufacturers, who are now counting their losses.”The notification came as a shock. We had no prior notice. It has destructed as much as 60-70% of our business,” said Vikram Singh of RoopArinna Fabricators Pvt Ltd, a solar thermal water heater manufacturer.Most industry players belive that ongoing projects will also be stalled. “I received an email from one of my clients on Friday, asking me to stop work. I have raw material worth Rs 1 crore at the site, an amount I doubt I will be able to recover now,” said Anil Azad, of Sunbirds Solar Power Systems. He added the decision will destroy 25-30 % of the market for solar thermal power heaters.Reportedly, many developers have asked manufacturers and installation parties to take back their equipment.The policy has stalled what was the beginning of the solar energy boom in the state. “As it is, solar water heater manufacturers are not looking at northern India. Haryana happened to be a lucrative market because of the policy. Now, we will have to look for other business avenues,” said Karan Taluja, of Meher Enterprises.Officials, when approached, said they had to pull back the policy because the government is planning to install photovoltaic solar panels on rooftops.
