Big Ups and Downs on Global Market

Submitted by Baerbel Epp on April 26, 2016
The global solar thermal market went into another year of notable decline in 2015. With 37.2 GWth, the newly installed glazed and unglazed collector capacity in the 18 largest countries was 14 % lower than in 2014 (43.4 GWth). Between 2013 and 2014, the decrease in these 18 major countries – which represent 95-97 % of the world market – had been 15 %. The further slowdown last year was the result of diminishing collector area figures in China (-17 %), and in Europe (nine biggest nations down by -5 %). The countries with the highest growth rates last year were Denmark (+55 %), Turkey (+10 %), Israel (+9 %) and Mexico (+8 %). The chart shows both 2015’s newly installed collector area, broken down by collector type – flat plate, vacuum tube and unglazed collector area, and the 2014-2015 growth rate (excluding China, whose 2015 market volume was 21-times larger than Turkey, which ranked second). China added 30.5 GWth in 2015 of which 12.6 % were flat plate collectors (5.5 million m2).

Taiwan and Japan: Commonalities and Differences

Submitted by Baerbel Epp on October 29, 2015

Taiwan and Japan have more in common as it seems at first glance: Both countries do not only belong to the same world region, but their 2014 market volume was of the same size too – around 100,000 m2 of newly installed collector area. And last but not least, vacuum tubes play only a minor role in both countries. Another factor which Taiwan and Japan have in common: they are hardly in the focus of the global solar thermal industry. One difference, however, is that Taiwan benefits from a support structure, whereas the Japanese industry is on its own – still, both markets are shrinking.
