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: HIMURJA as Inspirational Model for Market Development

Submitted by Baerbel Epp on October 9, 2012

The Himachal Pradesh Energy Development Agency (HIMURJA) has recently received the award  for the best state-based nodal agency in the areas of promotion and market development of solar water heaters from the Indian Ministry of New and Renewable Energy (MNRE). The state of Himachal Pradesh in the north of India has so far achieved a collector area of 12,550 m2. Nearly 75% of these installations have been set up over the last 3 years. The region’s scenic and peaceful landscape makes it a popular tourist spot. Most of the territory is more than 1,000 meters above sea level and is covered by mountains. The photo shows the collector installation on the roof of the Apple Country Resort in Manali, Himachal Pradesh.

India: “Solar thermal is a government priority”

Submitted by Baerbel Epp on September 7, 2012

India is one of the most dynamic solar thermal markets worldwide. Solarthermalworld.org spoke with Tarun Kapoor, Joint Secretary at the Ministry of New and Renewable Energy (MNRE), Government of India, about the fast-growing market in general and the difficulties with the market statistics in particular. Kapoor passed the Indian Administrative Service in 1987 and can look back at 24 years in government service as Director and Managing Director of departments dealing with renewable power generation. The Electrical Engineer headed the Department of Energy in the state government, before he took over as Joint Secretary at the MNRE two years ago.

Final Report on Market Assessment of Solar Water Heating Systems in Industrial Sectors (2011)

Submitted by Raquel Ponte Costa on August 3, 2012

This report was commissioned by India’s Ministry for New and Renewable Energy (MNRE) to estimate the realisable market potential for Solar Water Heating (SWH) systems in India’s different industrial sectors, and to prepare action plans for future development. The MNRE concluded that the industrial penetration of SWH would need scalability, innovative marketing, financing and service delivery mechanisms.

India: SMS Promotion Boosts Helpline Traffic

Submitted by Baerbel Epp on July 19, 2012

India has one of the largest mobile phone databases worldwide. This and the high market penetration (84%) prompted the Ministry of New and Renewable Energy (MNRE) to initiate a pilot project for an SMS-based (Short Message Service) solar thermal awareness campaign. Between January and April 2012, text messages pointing to the toll-free hotline for solar water heaters were sent to half a million prospective buyers of solar hot water systems, such as architects, car owners, doctors and real estate agencies.

India: 90 Process Heat Projects with Concentrating Collectors in Five Years

Submitted by Baerbel Epp on June 11, 2012

 Workshop on UNDP – GFE Project On 19 May 2012, the Joint Secretary of the Ministry of New and Renewable Energy (MNRE), Tarun Kapoor, announced the official launch of the initiative Market Development and Promotion of Solar Concentrator based Process Heat Applications. In cooperation with the United Nations Development Programme (UNDP), the MNRE will support 30 demonstration projects (15,000 m²) and 60 replication projects (30,000 m²) of process heat applications with concentrating solar thermal collectors across at least five different sectors between 2012 and 2017. The aim is to create a wealth of information about all of the supported projects, including feasibility studies, detailed project reports and performance results.

Market Assessment of Solar Water Heating Systems in Five Potential States/NCR Region (2011)

Submitted by Raquel Ponte Costa on June 6, 2012

This report is a deliverable of the “Global Solar Water Heating Transformation and Strengthening Initative”, jointly funded by the United Nations Development Programme (UNDP), the United Nations Environment Programme (UNEP) and the International Copper Association. In India, the commitment for SWH deployment has been supported by the government’s Ministry of New and Renewable Energy (MNRE).

Solar Water Heating Systems: A Review of Global Experiences (2010)

Submitted by Raquel Ponte Costa on May 29, 2012

Prepared jointly by India’s Ministry of New and Renewable Energy (MNRE) and the Renewable Energy and Energy Efficiency Partnership (REEEP), this report gives an overview of the Solar Water Heating Systems (SWHS) market in India over the last decade, and counterpoints it against broader global developments. After looking at global trends in market development, the document gives summaries of UNDP-GEF and REEEP experiences of SWHS projects. This includes summaries of specific projects over the last five years.

India: Kerala State Subsidy Meets Targets

Submitted by Baerbel Epp on April 24, 2012

 Mohanan Vaisakham The new subsidy scheme in the southern Indian state of Kerala has almost reached its aims: The programme subsidised 5,000 m² of collector area in the first three months of 2012, according to the Agency for Non-Conventional Energy and Rural Technology (ANERT). As ANERT Scientist Perumpalot Valsaraj explains, the goal was to support 500 m² of solar collector systems for fish drying, as well as 5,000 m² of residential solar water heaters, of which 40 % were to be equipped with vacuum tube collectors. The photo shows Mohanan Vaisakham, one of the solar water heater owners who profited from the ANERT scheme. The incentive is paid additionally to the federal 30 % investment subsidy.

India: MNRE Memorandum Bans Import of Storage Tanks, Manifolds and Mounting Systems

Submitted by Baerbel Epp on December 4, 2011

 Evacuated Tube Collectors Because of a comparably lower price, vacuum tube collectors are becoming more and more popular in India. Based on a capacity of 100 litres of warm water per day, an average thermosiphon system with flat plate collectors is sold at INR 20,000 (EUR 208), whereas a solar water heater with a vacuum tube collector costs on average INR 16,000 (EUR 167). To protect the business of the around 60 flat plate collector manufacturers in India, the Ministry of New and Renewable Energy (MNRE) issued a memorandum on 20 October 2011. Its most important sentence says that, “manufacturers shall import no components other than ETCs (Evacuated Tube Collectors)”.
