50 kW Dish/Stirling System

Riyadh, Saudi Arabia, 1986

The project involved the construction of two 50 kW dish/Stirling systems close to Riyadh in Saudi Arabia. These were the first large concentrators built using metal membrane technology, and they still are the largest dish/Stirling systems worldwide. The highly efficient Stirling motors were equipped for solar operation for the first time and a very innovative, state of the art drive and control system was developed.
The units are fully grid independent and were operated continuously until the mid 90s.
