Solar process heat is an upcoming new business field for the solar thermal industry. The IEA SHC Programme and the IEA SolarPACES Programme have now developed guidelines that describe in detail how to incorporate solar heat into industrial processes.
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.
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.
The solar thermal industry is debating whether it should introduce its own efficiency label for solar collectors. Uwe Trenkner, who was secretary general of the European Solar Thermal Industry Federation ESTIF from 2005 to 2009, explains in a commentary why he rejects this idea.
