Germany: Solar thermal loses out to other renewables

In Germany 2017 was the weakest year for solar thermal collector sales in more than a decade, according to the combined statistics by associations BDH and BSW-Solar. Their data reveals that only 78,000 systems were sold last year. The newly installed collector area added up to 625,000 m², down 16 % from 2016 and as much as 72 % from the boom year of 2008. It was an astonishingly poor showing, considering the strong growth in the construction industry and the high incentive amounts available in Germany.

District heating shows lower total socio-economic cost in future energy system

What would the economic impact on a future energy system be if one were to unlock the full solar thermal potential in Austria, Denmark, Germany and Italy? According to a study conducted by Aalborg University as part of the IEA SHC Task 52 research project Solar Heat and Energy Economics in Urban Environments, exploiting the maximum potential will result in significant cost reductions if solar heat is supplied not individually but by district heating.

Three ways to read European market statistics

There is more than one way to read 2016’s market statistics published by Solar Heat Europe about 2 months ago. One could emphasise the great achievements made in reducing emissions and creating jobs in the solar heating and cooling sector in Europe (first part). One could likewise point to Denmark as a leader in solar district heating. A third possibility would be to concentrate on the continued decline in most key markets in Europe and the stark difference between renewable heating targets and their fulfilment in many countries (second part).

Namibia’s path to a solar thermal future

The Namibia Solar Thermal Technology (STT) Roadmap outlines the country’s path to 1.5 million m² of collector area by 2030. The aim is to have an average 0.5 m² installed per inhabitant by then.

Global certification saves money and time

To enter new markets, solar thermal collector manufacturers need to have their products tested and certified as meeting local standards. Thanks to GSCN, the Global Solar Certification Network, they can complete several certification processes with only one test cycle.

Solar thermal loses popularity in Malta

The Mediterranean island of Malta is a paradise for all those who enjoy basking in the sun. But despite the country’s high levels of solar irradiation, its people haven’t yet warmed to solar thermal. A recent study by Malta’s Regulator for Energy and Water Services (REWS) has shown a declining number of new subsidised solar water heaters.

French SOCOL network analyses market drivers and barriers

Preliminary data from 2017 shows the newly installed collector to have been as little as 50,000 m², a decrease of 15 % compared to the year prior. Only multi-family properties and large-scale systems seem to be bucking the trend. (Source: Uniclima)

The SOCOL network has become more involved than ever in shaping the future of the French solar thermal sector, having grown quickly from just 155 experts in 2013 to 2,500 today. Great efforts are being made to improve the image of solar thermal as a cost-effective, reliable technology for commercial applications. Despite the favourable environment, the French market has experienced a notable decline over recent years.
