India: First Solar Process Heat Systems with CPC-Mirror Vacuum Tube Collectors

Submitted by Baerbel Epp on January 7, 2017
Oorja LadakhIndia has been witnessing renewed interest in solar thermal in the wake of some successful installations. Dish-type concentrating systems have the potential to generate hot water above 100 °C. But in many places, insufficient space or unsuitable roof structures are roadblocks to increased deployment. Several Indian start-ups have used evacuated tube collectors (ETC) with compound parabolic concentrators (CPC), popularly known as non-imaging collectors in India, for solar process heat applications which require medium-pressure steam at around 150 °C. These collectors consist of evacuated double-glass tubes with bent aluminium mirrors underneath. The CPC mirror guarantees that fewer tubes are required per unit area and over 90 % of the gross collector area is used optically. So far, the aluminium sheets for the systems have been imported, but one local manufacturer will start operations soon.

Portuguese Car Components Supplier enters Solar Thermal Industry

Submitted by Baerbel Epp on April 21, 2011

 MCG Solar Sales Director Paulo Neves” MCG has plans to start producing a flat plate collector with a Compound Parabolic Concentrator (CPC) in the near future. The Portuguese company located in Carregado 50 km north of Lisbon has manufactured components for the automotive industry since 1978. “MCG possesses know-how in the area of mass assembly and production. Equipped with this knowledge, it could gain the pole position on the solar thermal market and the strength to maintain it,” MCG Solar Sales Director Paulo Neves says.
