SOLAR DISH/STIRLING POWER SYSTEMS
McDonnell Douglas/Southern of California
California Edison 25 kW dish/Stirling system. The 944 square foot concentrator consists of 82 spherically curved glass mirrors each 3 foot by 4 foot. The United Stirling 4-95 Mark II engine (4 cylinders of 95 cc displacement) uses hydrogen as the working pressure at a maximum gas pressure of 2900psi.. This engine delivered 25kW output at 1000W/m2 insolation.
Advnco/Vanguard 25 kW dish/Stirling system installed at Rancho Mirage, California.
The Vanguard concentrator is approximately 11 meters in diameter and made of 366 mirror facets, each facet measures 18 by 24 inches. The engine used is a United Stirling AB (USAB) Model 4-95 Mark II driving a commercial 480 volt/ac 60-Hz alternator.
