India: Investment in Tank and Vacuum Tube Collector Production

Submitted by Baerbel Epp on November 25, 2013

The solar thermal industry in India is serving the strongly growing demand with additional manufacturing capacities of solar water heaters based on vacuum tube technology. This news piece presents two examples of solar manufacturers, V-Guard Industries and Inter Solar Systems, which have invested INR 180 million (EUR 2.1 million) and INR 100 million (EUR 1.2 million) in new factories, respectively. The trend towards vacuum tube technology has also been confirmed by the latest industry survey carried out by German agency solrico in September/October 2013. The seven solar water heater companies which manufacture collectors based on vacuum tubes and took part in the survey were able to increase their production by, on average, 58 % in 2012 compared to the previous year. The 14 flat plate manufacturers, on the other hand, reported stagnating production figures for 2012.
