While high efficiency, space-qualified solar cells are in themselves costly, integrating them into a high performance Photovoltaic Assembly (PVA) using conventional glassing, interconnecting, stringing, tiling and laydown techniques can double their cost in $/Watt. Our solar cells and CICs are the highest efficiency commercially available products in the industry offering more than 4MW of power delivered for flight missions. Boeing's Spectrolab to Power NASA's Roman Space Telescope Spectrolab offers a range of GaInP/GaAs/Ge lattice matched 3J solar cells with efficiencies reaching 32%. The greatest share of Spectrolab's product deliveries are fully assembled space solar panels based on a customer's specifications. With power levels up to 2,000W and a cell layout configurable to any bus voltage, we can optimize the solar array for your mission in LEO, MEO, GEO or interplanetary. Northrop Grumman is the industry leader in the design, development, and production of unique and turnkey solar array systems that provide electrical power to spacecraft systems. Our lightweight arrays have powered a variety of critical missions, including: Photovoltaic subassemblies feature the.
