India: Statistics to Determine Vacuum Tube Market Share

Submitted by Baerbel Epp on February 17, 2015
India Market StatisticsFlat plate collectors – India’s dominant solar thermal technology about a decade ago – has lost a significant portion of its market share in recent years. Although the Ministry of New and Renewable Energy (MNRE), the Indian authority responsible for solar heating statistics, has never published an official figure for the market share of vacuum tube collectors in a given year, a June 2013 interview with former MNRE Director Veena Sinha revealed that the share of vacuum tubes in the residential sector was close to 60 % in Financial Year 2012-2013. The 2014 statistics of online portal Solarwhin still show just about the same percentage: Of the 607,751 m² of subsidised collector area in 2014, 61 % were vacuum tube collectors (369,292) and 39 % flat plate collectors (238,459 m²) – see also the attached PDF, which resulted from a query to the online Solarwhin database. The pie chart above shows the Indian states in which most of the collector area was installed in 2014.

India: First Vacuum Tube Testing Centre Established

Submitted by Baerbel Epp on December 2, 2014
Pune UniversityThe School of Energy Studies at Savitribai Phule Pune University, located in Maharashtra state, has set up India’s first vacuum tube testing centre. The investment was around INR 4 million (about EUR 50,000) and was funded entirely by the Ministry of New and Renewable Energy (MNRE). “Considering the expertise available at our university – in physics, electronics, as well as chemistry - it was the obvious choice,” Professor Subhash Ghaisas, Director of the School of Energy Studies, said. His institution also has the first testing centre for concentrating solar thermal technology, which was inaugurated in July 2014.

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.

The European solar thermal markets are growing at high rates altogether. During the last three years alone, the average annual growth rate finally settled at an impressive 35 % margin. And, dozens of new tanks and collector manufactures opened their doors in the last two years.

This rapid increase in all areas of the solar thermal industry presents a big challenge for all of its market players – component manufacturers as well as suppliers of material and machinery.
