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.


Pressure or drain-back? The new solar heating system from Vaillant can do both!

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.


PV instead of solar thermal: solar pioneer Andreas Wagner heats water using electricity

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.
