Energy galore
The amount of solar energy that falls on the Earth’s land areas over one year is almost 2000 times greater than the entire world’s energy demand. Given the global climate problem, using this potential in the best possible way seems self-evident.


The advantages of converting light into electricity directly are well known: solar power contributes to protecting the environment, reduces the cost of electricity transmission and provides an independent and affordable energy supply.

Solar Thermal Energy

Solar thermal energy is defined as using solar power to provide heat. The heat can be used for heating in the home and for heating domestic water, as well as for process heat in industry and for steam generation in power stations and even for cooling.
