Puducherry firm develops solar-powe​red portable houses

According to report,  a Puducherry-based instrumentation firm has developed multi-purpose solar-powered portable houses that, apart from serving as small residences, can also serve as site offices, kiosks for vending food, beverages, vegetables and groceries, tourists information centres and security guard cabins.

Chemin Controls and Instrumentation Private Limited will formally launch the houses during the five-day renewable energy and sustainable living products and services’ exhibition proposed by the Angiras Charitable Trust, a network of Indian alumni from the German University for Sustainable Solutions and the Renewable Energy Agency Puducherry (Reap) at Gandhi Thidal on October 9.

The five photovoltaic modules fitted on the roof of the 10 feet by 20 feet house will generate 1,250 KW power from solar energy. This will be sufficient to power three tube lights, two table fans and two computers. The power generated can be stored for 12 hours, and the cost of the solar-powered house will be about Rs 10 lakh. The house can be modified into a scientific laboratory, site offices and security guard cabins as per the requirement of the clients.

“The houses are built in portable dimensions using structural steel and modern insulated materials. They can be dismantled, transported and reassembled easily,” Chemin Controls and Instrumentation Private Limited chairman cum managing director P Rangaraj told TOI.

He said the steep decline in the cost of generating power from solar energy encouraged the firm to launch solar-powered houses. “The unit rate of power from solar energy was almost double the government electricity tariff two years ago. Of late due to technological advancements, the cost has come down drastically. In the next two years, the unit rate of power from solar energy will be less than the government electricity tariff,” he said.

In the absence of solar grid connection in Puducherry, the firm has no other option than to utilise rooftop standard solar system. “Puducherry does not have solar grid connection facility that supplies excess power beyond consumption to the utility grid and records the excess power supplied in the meters through reverse reading. Hence we opted for rooftop standard solar power system,” Rangaraj said.

The major clients of the firm specialising on instrumentation, automation and control systems include Union defence ministry, Department of Space and Technology, Bhabha Atomic Research Centre, Bharat Heavy Electricals Limited, National Thermal Power Corporation and Reliance Refineries among others.
