Solar water heaters is one area where companies could have excellent business opportunities in India, given that large parts of the country have excellent sunshine.
Tata BP Solar India (TBS) has tied up with Dubai-based Eurostar Solar Energy (ESE) to meet the rising demand for solar thermal water heating systems in the region.
ESE, the newly launched group company of EUROSTAR Group, is an active proponent for renewable energy in the region offering expertise in the design, supply, installation, commissioning and after sales service of solar water heating systems (provided by TBS) and PV systems.
TBS has over 2.5 million liters day of systems already installed in India. I’m not sure whether this can be considered a large number for a country with as much population as India, but it sure looks like a start. (Some comparison data: In India, as of 2005, over one million square metres of solar water heating systems have been installed excluding the generic storage tanks. However, the Ministry of New and Renewable Energy Sources has calculated that the total potential is more than 140 million square metres).
