SOLAR
CONCENTRATING COLLECTORS FOR SPACECRAFT APPLICATIONS
Features:
• Solar Concentration Ratio = 2.36/1 (Number of cells
reduced by a factor of 0.424 relative to flat plate collector panels)
• 7.9" x 9.76" Modules, which can be combined into any size panel
• Each module provides 16.8 VOLTS D.C. at greater than 25% efficiency
• Power/Weight Figure of Merit greater than 150 watts/Kg.
• Can use either EMCORE or SPECTROLAB Triple Junction, 26% efficiency, GaAs
solar cells with 99% effective packing factor
• "Egg Crate" PYRAMID OPTIC Solar Concentrator provides
extremely rigid solar panel structure of very light weight
• Front and rear high emissivity thermal radiation to cold space
results in solar cell temperatures equivalent to or less
than flat plate cell temperatures
• WIDE ACCEPTANCE ANGLE minimizes solar tracking requirements (See
Angular Response Plot)
• Covered by U.S. Patent 6,034,319 (Technical paper available)
• Electro-statically clean design minimizes electrostatic voltages on cells
• To be flight qualified on CUBESAT SPACECRAFT in 2006
• EXTREMELY COST EFFECTIVE PRICE: $4,900- PER MODULE ($254-/WATT)
