India: Drop Vacuum Tube Collector Subsidy?

Submitted by Baerbel Epp on June 14, 2013

To protect local solar photovoltaic manufacturers, the Indian government has made it mandatory in its National Solar Mission to use locally made cells and modules. There is no such rule for the solar thermal sector, in which the state subsidises 30 to 60 % of the price of a solar water heater, although a growing number of vacuum tubes have been imported from China. First assessments of the database of the national incentive programme SOLARWHIN show that 75 % of the applications include vacuum tubes and only industrial applications have used flat plate collectors (FPCs). Malaviya Solar Energy Consultancy has asked a few of the leading manufacturers if the subsidies for solar water heaters based on vacuum tubes should be removed, in order to protect the local industry and also to reduce the government’s financial burden with the subsidy scheme.

India: Flat Plate vs Vacuum Tube Technology

Submitted by Baerbel Epp on November 19, 2012

Until now, the Indian solar thermal market has been dominated by flat plate collectors (FPCs). FPCs have several advantages, with the main being robust and long-lasting. In a price-sensitive market such as the Indian one, however, vacuum tube collectors (VTCs) have gained a foothold over the last years because the systems are 30% to 40% cheaper if the glass tubes are imported from China. Although there is no official data available, VTCs are said to have reached a 35% share in the Indian market. In the fiscal year 2011/2012, market volume reached a newly installed collector area of 1 million m² (see interview with Tarun Kapoor). The photo shows flat plate collectors on high-rise, residential buildings in western India.

India: Two Solar Desalination Pilot Projects by Tinox-Mage

Submitted by Baerbel Epp on August 28, 2010

 MiniSal 1000” One box on three Euro palettes brings the desalination unit to the site: The MiniSal 1000 purifies up to 1,000 litres of sea or brackish water per day like this installation in the town of Al-Hail in Oman. The first two pilot projects in India are already under way.
