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.

Things you need to know about the new heating label!

The efficiency label for new heating systems, water heaters and heat storage systems went into effect on 26 September. Many specialist publications, including our own, have been reporting on the topic for months. Trade associations have also been flooding the market with information, making it hard to keep track. For this reason, we decided to put together a summary of the most important points.

A frugal place to unwind

In the Goona mountain restaurant you can relax at the fire­side after a day on the slopes. Still, it is worth to give a second thought at how the energy consumed up in the mountains has been generated. (Photo: Fortner ­Speichertechnik)

The mountain restaurant Goona needs to draw 450 kWh of energy every day to supply its guests with good food in a cosy dining room. To cover that demand, it taps into three environment-friendly sources: the power of the sun, the fire of a wood-burning stove, and the waste heat from a refrigeration system. The three complement each other perfectly. Here you can see how:

Solvis recently introduced three new large-area collectors. According to the manufacturer, they are improved versions of the existing range of large-area collectors in different sizes that achieve significantly higher yields than previous models.
