The Austrian OEM solar collector manufacturer GREENoneTEC has now begun selling solar energy systems under its own name for the first time. In Central and Northern Europe, however, this will go largely unnoticed.
At the start of the Intersolar Europe, particularly innovative solutions in the areas 'Photovoltaics' and 'Solar Projects in Europe' received the Intersolar Award. The prize was awarded for the eighth time as part of an official ceremony at the trade fair's Innovation Exchange.
Solar thermal power plants with highly concentrating collectors that are located in deserts usually have an abundance of sunlight to generate energy with. Unfortunately, the mirrors must also be cleaned regularly and water is scarce and expensive in such regions. Maintenance work in remote areas is time-consuming and not exactly inexpensive.
The system provider Vaillant has introduced a new entry-level system for solar water heating. What makes it special is that it can be used for both pressurised and drain-back systems. The system is available with storage tank capacities of 150, 250 or 350 litres. The standard version is equipped with a high-efficiency pump. For higher discharge heights in drain-back systems, the pump group has room for a second pump.
Up till now, when people spoke about thermal solar energy, they meant generating heat with solar collectors. But an increasing number of companies are also offering devices that heat water using solar electricity. Awasol may be the newest provider of such systems on the market, but the person behind it is no newcomer to the industry. Its managing director is Andreas Wagner, co-founder of Wagner & Co., which played a pioneering role in the solar thermal industry.
