India: New Energy Building Regulations to Boost Solar Heating Market

Submitted by Baerbel Epp on July 24, 2017
Jaideep MalaviyaThis June, the Indian Ministry of Power published an updated version of the Energy Conservation Building Code (ECBC) developed by the Indian Bureau of Energy Efficiency (BEE). The ECBC has established energy efficiency standards and a solar share of hot water demand for newbuilds and refurbished homes and commercial buildings across India. But it will be the task of municipal corporations to issue notifications which mandate compliance with ECBC 2017 regulations in the construction sector in their area. The ECBC was launched in 2007 based on the Energy Conservation Act from 2001. The photo shows a vacuum tube installation for solar process heat at automotive manufacturer JBM Group. Solar industry stakeholders have said that it was regrettable that industrial buildings and applications are not covered by the ECBC 2017.

India: Industry Demands Equally Assertive Solar Thermal Publicity

Submitted by Baerbel Epp on September 20, 2016
India REI 16 PanelThe Indian government should provide the same assertive publicity for solar thermal technology as it had for solar PV because the population still needed to be made aware of the benefits of solar water heating. This was the major concern raised during the panel discussion Policy and Regulatory Framework for Solar Water Heater Market Development in India moderated by Jaideep Malaviya (third from right), Secretary General of the Solar Thermal Federation of India (STFI). Five industry representatives took part in the event held during the Renewable Energy India Exhibition and Conference 2016 near New Delhi at the beginning of September (from left to right): Rigal Patel (Redsun Solar), Bhoovarahan Thirumalai (Aspiration Energy), Devinder Kaushal (Inter Solar Systems), Saurabh Bhandari (Solarmaxx) and Chandrakant Shah (Kosol Hiramrut Energies).

India: Local Manufacturer Exports First Pool Heating System to Oman

Submitted by Baerbel Epp on July 22, 2016
MuscatIndian collector manufacturer Inter Solar Systems (ISS) has recently put into operation a solar swimming pool heating system at a private villa in Muscat, the capital of Oman. Local solar thermal dealer Continental Shelf of Solar Tech purchased the 60 m² flat plate collector system from ISS to keep a large private pool inside a villa at comfortable 25 °C all year round. The photo provides a view over the coastal town of Muscat, which is said to be the world’s smallest capital with a population of only 32,000.
 

India: Solar System Suppliers Call for Solar Process Heat Obligation

Submitted by Baerbel Epp on November 11, 2015
SKF TechnologiesThe Indian industry imports 80 % of the oil it consumes for heating, boiling, drying or other purposes. The government of India has spent USD 112.748 billion in financial year 2014-15 on the import of these 189.43 million tons of crude oil. Solar thermal is seen as a key technology for reducing government spending and greenhouse gas emissions in the industry on the subcontinent. Despite being heavily subsidised, solar process heat installations are still rare across the country. Now, the solar thermal industry is calling for additional regulations in form of a Renewable Heating Obligation to speed up the deployment of solar thermal technology in the manufacturing sector. The photo shows a solar concentrating system on the roof of bearing manufacturer SKF Technologies in Mysore in southern India.

India: Solar Process Heat with less than 18-Month Payback Period

Submitted by Baerbel Epp on July 14, 2015
Sharman Shawls“Where there’s a will, there’s a way” is the slogan at Sharman Shawls, one of India’s leading garment industry and export companies. Based in Punjab state in northern India, Sharman Shawls uses diesel to meet the hot water requirements for dyeing, bleaching and washing garments. The enterprise’s daily consumption is close to 200,000 litres of water and the processes require almost 1,700 litres of diesel per day. 180 flat plate collectors preheat hot water to 80 °C, saving 82 litres of diesel at 300 days a year. Space constraints have limited the diesel saving per day to 5 %.

India: New Five-Year Guarantee on Solar Tanks

Submitted by Baerbel Epp on December 2, 2013

Many Indian regions suffer from bad water quality: More than 75% of the country has moderately hard to very hard water. Chloride levels are also high in specific areas when water is obtained from boreholes. The “desired” legal chloride limit for drinking water is 0.25 g/litre, but is allowed to increase to 1 g /litre. As a result, solar thermal storage tanks gradually corrode and tend to develop leaks. Statistics obtained from the national Helpline show that over 70% of product-related complaints are about leakages in storage tanks. The photo shows a corroded extremely scaled hot water tank.

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: Industry Shifts to Vacuum Tube Collectors

Submitted by Baerbel Epp on May 1, 2013

The renewed growth of the Indian solar thermal market has existing manufacturers expanding their production capacities and integrating vertically. Solar water heaters based on vacuum tube collectors are a popular product, already covering around 40 % of the newly installed 1 million m2 collector area in 2011/2012, according to estimations by market stakeholders. An example is Inter Solar Systems from the northern Indian city of Chandigarh. The company has invested INR 8.6 million (about EUR 120,000) in a completely new and semi-automated solar tank production plant, which was commissioned at the end of last year. The photo shows a punching machine for vacuum tube collector tanks.
