"The power pack, a combination of solar PV panels, inverter and battery, will help consumers enjoy uninterrupted power supply for up to eight hours at an affordable cost," the company said in a statement.
The product called Tata Dynamo works like a regular inverter that uses solar energy as its primary source of power, it said.
The system charges itself while powering appliances and automatically shifts to regular electricity when sunlight is unavailable, it added.
Depending on weather conditions, the system can provide back-up of four to eight hours for appliances like LED and CFL lights, fans and televisions.
The system has been designed for simple and easy installation and maintenance-free operations and has a life expectancy of eight to 10 years.
A 30 per cent subsidy from the Ministry of New and Renewable Energy makes the product more affordable for consumers, according to the statement, which did not mention its price.
"Tata Dynamo is a great way to switch to solar. It will help both urban and rural middle class manage power cuts better while reducing their power bills substantially," said Ajay Goel, CEO of Tata Power Solar.
The product will be available across the country through Tata Power Solar's over 1,000-dealer network.
