24/7 High Performance Solar Power plant

How the new concentrating collectors works ?

The functionality is the same as in Father Himalaya's solar oven (3), which has been known for 120 years. 

Since the optical connection of the individual rings in such solar ovens is very complex and material-intensive, the outer parts of the rings have been removed so that only the central segments remain, which are connected to each other on a simple wire framework. This procedure has the particular advantage that these small parts are used to create an unprecedentedly light and cheap multifocal optic.

While here a 7 x 7 meter bifocal optic would weigh only 160 kilograms, other ring concentrators (4) weigh several tons.

High-performance solar power plant

This high-performance solar power plant with 5 collectors of a new type optics is specially developed for desert areas. The glass surfaces are cleaned (6) several times a day with compressed air. Therefore, there will be no losses due to dusting of the mirrors. Operating and maintenance costs are kept to a minimum.

These collectors with 40 CPV-ADAM modules have an output of 120 kWel and 225 kWth.

 

The entire system is equipped with biaxial tracking to the sun.

A highly efficient CPV-ADAM Modules

Each of the AZUR SPACE (7) modules has 3.2 kWel

and 6 kW of thermal power output at 700 suns. Electrical protection of solar cells against reverse voltage is provided by bypass diodes. The solar cells and diodes within ADAM are completely interconnected and only electrical connection to the external circuitry and connection to cooling system shall be provided by system integrator. For requested thermal management of the module, an active liquid cooling system is necessary.
