What are the largest cost items of a thermo-solar-power plant - the mirror fields?
In the development of the solar fields, we have gone completely new ways.We use the revolutionary construction technology of the SOTA-DOMUS SWISSand construct both the mirrors and the supporting structure from the basic materials. The 6m long solar mirrors have a high performance honeycomb core and an upper and lower layer of extremely stable ceramic.This pairing has the following advantages to conventional metal mirrors.•Extremely stiff mirror construction•Exceptional precision•The expansion coefficient of the supporting structure is identical with the mirror, because everything is of mineral origin. •Since there is neither flaking paint nor corrosion, as is the case with metallic constructions, one can assume that the mirrors are maintenance-free for many decades.Also with the mirror allocation and the glass choice we go completely new ways.The voluminous supporting structure of the solar mirrors is manufactured on site.A special 0.8mm thick flexible glass is delivered to the production site on rolls.At the production site, the glass is chemically silver-plated and, after vacuum drying, immediately applied to the mirror substrate using double-sided adhesive high barrier film.Through this process, for which a patent has been applied, the supporting structure and the high-performance mirror are permanently joined together.The production of the mirror carrier, the mirroring of the glass and the mirror application take place in a process automat.Thus the production becomes unrivalled inexpensive and fast.A fully automatic machine is capable of producing up to 1.3 million m². This corresponds to the solar mirror size required for approx. 1GW. 1GW corresponds to the output of a medium nuclear power plant.
The supporting structure, into which the linear sun mirrors are suspended, is also made of a glass reinforced mineral.This means that the supporting structure can be produced quickly and cheaply on site.The structure also does not require any paint or corrosion protection.It is absolutely maintenance-free for many decades.
Maintenance work is virtually eliminated over a very long period of time.For an optimal function of the mirrors, these must always be absolutely clean, so that the reflection is always perfect.To ensure this, the linear mirrors rotate downwards at night and are then perfectly cleaned by several cleaning robots. Parallel to the cleaning, the mirrors are optically measured so that even the smallest errors can be detected immediately.Due to the fully automatic cleaning of the mirror fields, the operation of the system is almost fully automated.
