Residential area uses solar thermal and district heating

The project Gutleutmatten in the German city of Freiburg will produce heat for a residential district using 2,287 m² of solar collectors. (Graphic: Office of city planning Freiburg im Breisgau)

A city district in the German town Freiburg will use a solar thermal system for heating and hot water production. During periods with low solar irradiation, the buildings will be supplied with heat from a district heating system.

Scottish Solar Home: Adding value is not about adding subsidy

Both the solar thermal collectors and the PV panels are from the same supplier, Viridian Solar, and are designed to look nearly exactly the same. (Photo: Solar Kingdom Ltd)

A Scottish ultra-low carbon home won a prestigious Solar Award using a very uncommon solar installation. Ignoring some subsidies schemes, both PV and solar thermal panels are arranged in a quite unusual east-west-configuration.

Collectors last a long time

What happens to a collector when it is exposed to the elements day in and day out? Does it lose a significant amount of its performance over the years or might the frame even crumble at some point? Researchers did not find evidence for any of this. Modern, industrially manufactured collectors are resilient. And not just in the moderate climate of central Europe, but also under extreme conditions such as in tropical India.

Solar Keymark for full plastic collector

The new 100 % polymer collector of Sunlumo is very light weight. However, primarily it is designed to reduce costs. (Photo: Sunlumo)

Austrian solar developer Sunlumo announced that its full plastic solar collector is now the first 100 % plastic collector from Europe awarded with the Solar Keymark certification.

Germany: Yield-dependent funding for solar thermal is off to a good start

Large solar thermal systems are still a small market segment. Funding in this sector is now also based on yield, not just on surface area. (Photo: Ritter)

On 1 April, Germany introduced yield-dependent funding for solar thermal systems. Even if the funding does not go as far as some had hoped, it is apparently enjoying a high level of acceptance.

Installers avoid the Heat Incentive

Like in most European countries solar thermal in the UK is not seen as an equal compared to photovoltaics. (Photo: The Solar Design Company)

During 2015, the UK’s solar thermal market for single households continued its long term decline which started over 5 years ago. This was the opposite of the intended effect of all the government’s incentive schemes over this period but without doubt all these have failed for solar thermal.
