Rising demand for solar heat in large buildings and industry

Submitted by Baerbel Epp on June 6, 2018
SHW 1By the end of 2017, the market for solar heating and cooling had grown by 472 GWth, which again made it the largest for solar energy in the world. The one for photovoltaic systems gained 402 GWp to become the second-largest, and 5 GWel was enough for concentrating solar power to rank third, according to the latest Solar Heat Worldwide report. The report also highlights the rising use of megawatt-class solar heating and cooling solutions for large public and residential buildings, as well as factories. It was launched at the end of May by the IEA Solar Heating and Cooling Programme (IEA SHC). Lead author is the Austrian research institute AEE INTEC.

Kyrgyzstan’s capital sees 0.5 MW SDH plant being built

Submitted by Baerbel Epp on December 19, 2017
Bishkek City HallIn September, the then deputy PM of Kyrgyzstan, Duishenbek Zilaliev, attended the inauguration of a 0.5 MW solar district heating plant in the capital Bishkek. The press release on the event – published by the media and communications department of Bishkek’s city hall on 22 September – also mentioned the operator of the solar field, the Bishkekteploenergo municipal utility, the largest thermal energy provider in the city. The national Environmental Protection Fund supported the project financially by offering a grant of Kyrgyzstani Som (KGS) 10.6 million – 72 % of the total investment costs of KGS 14.8 million (around USD 212,000).

Simulation Study of Solar Thermal Systems Consisting of Uncovered Collectors and/or an Air-to-Water Heat Exchanger (2006)

Submitted by Hans Craen on October 30, 2009

This research paper from 2006 looks into a simulation exercise of solar thermal systems consisting of uncovered solar collectors and/or air-to-water heat exchangers. The aim is to optimise their functioning and to compare the performances. This simulation has been carried out for the district heating net in Bishkek, Kyrgyzstan.

The simulation of this so-called multicomponent solar thermal system looks into a method to preheat cold water by using solar irradiance as well as heat of the ambient air.
