The Indian state of Rajasthan has strongly supported the market for solar thermal technology. Since 2004, the state in the northwest of India has had a comprehensive mandatory law for solar water heaters: Solar energy use has been an essential requirement in setting up new hospitals, sports complexes, swimming pools, hostels, barracks, hotels, industrial buildings in which hot water is needed to process the goods, as well as public buildings and residential buildings with a plot size of 500 m² and above. In 2011, the state government has also granted an indirect subsidy to residential users of Solar Water Heaters (SWH). Having come into force three months ago, the scheme allows every SWH user to receive a rebate on its electricity bill of INR 0.25 INR/kWh of electricity, capped at a maximum of INR 300 per month – independent of the age of the system.

The commercial solar thermal market is gaining importance in South Korea. According to the Korea New and Renewable Energy Center (KNREC), only 43 % of the glazed and subsidised collector area in 2010 was installed in residential housing. The majority of systems were set up in public buildings because of a mandatory renewable law, and in social welfare facilities due to a 50 % investment subsidy. The KNREC pie chart of the collector market in 2010 adds up to 69,805 m². The statistics do not include thermosiphon systems (not subsidised by the government), as well as certain not certified types of imported vacuum tube collector systems.

A satisfying record: The Indian city of Rajkot in Gujarat state, Western India, has seen the installation of more than 16,000 residential systems and over 700 commercial solar water heating systems since the Municipal Corporation implemented a solar building bye-law in March 2004.

Two years – that is how long California has already been waiting for a “200,000 solar roof programme“. After the Californian Public Utilities Commission (CPUC) published its “Proposed Decision“ in November, the programme may finally become reality next year.
