Rank Equipment for Solar Energy - Energy - Solar Power

Solar energy is the most abundant energy source on Earth. By capturing heat, solar thermal energy can be used to generate electricity through Rank equipment.

Solar collection technologies
Parabolic trough

They consist of a curved cylindrical mirror that reflects direct solar radiation on a glass tube located along the cylinder, positioned at the focal point of the reflectors.


It is a series of long, narrow, low-curvature (or even flat) mirrors that focus light on one or more linear receivers located on the mirrors.

Evacuated tubes

They are glass tubes, introduced, one by one, in another glass tube between which the vacuum is made as insulation, and which have a higher performance than flat plates at high temperatures of hot water.
