Bangalore, Jan 9 (IANS): Leading energy solutions provider Tata Power Solar Thursday unveiled a new solar power system to generate one kilo volt-ampere (kva) for providing uninterrupted power supply for eight hours at affordable cost.

"Our latest product - Tata Dynamo -- gives users easy option to switch over to solar energy for at least eight hours of uninterrupted power supply at lower cost," Tata group company chief executive Ajay Goel said in a statement here.

The intelligent system comprising solar panels, inverter and battery charges itself while powering connected appliances through solar power, which is its primary source of energy.

"In the absence of sunlight, Dynamo automatically shifts to regular electricity. The system provides four-to-eight hours of back-up to appliances such as lights, fans, television and air cooler," Goel said.

As state-run and private utilities are not able to meet the growing energy needs of even households and smaller businesses, forcing many of them to use diesel generators during power cuts, Dynamo is an eco-friendly substitute for load-shedding, he said.

"Studies show that households spend on average Rs.1,500 per month on grid power and additional cost on operating a diesel generator. By investing in Dynamo, its cost can be recovered in 18 months while availing uninterrupted power without extra cost," Goel claimed.

The product, with 10-year lifespan, also benefits from the 30 percent subsidy the ministry of new and renewable energy provides on solar-based devices to promote green energy.

"Dynamo helps both urban and rural middle class to manage power cuts better while reducing energy bills substantially. The system is also easy to install and is power packed with features," Goel added.

As a wholly owned subsidiary of Tata Power, the company has three manufacturing units and has 40 service centres across the country.

The company also operates a 180 megawatt module and cell manufacturing facility in the city.

"We have completed 70 mw of ground-mount utility scale and 30mw of rooftop projects across the country during last fiscal," the company said in the statement.
