TECSTAR has been awarded the world’s largest contract for triple junction solar cell assemblies by Lockheed Martin Missiles and Space (LMMS), Sunnyvale, CA. The assemblies will be used on Lockheed’s A2100 satellite bus. TECSTAR will provide 161kW of solar cell power (more than 200.000 cells) to LMMS through December of 2000. The triple junction solar cells (4x6 cm²) were developed by TECSTAR in conjunction with NASA and the USAF and currently power the Deep Space 1, TRACE, and Mightysat 1 satellites. TECSTAR is producing cells with efficiency as high as 24.6 %, higher than any claimed production efficiency of its two nearest competitors.

TECSTAR is "proud to be a strategic partner of LMMS and signed the long term agreement to give them the highest efficiency solar cell assemblies
in production world-wide". TECSTAR, Inc. powered NASA’s hugely successful Mars Pathfinder mission with its solar cell assemblies. The company has been manufacturing solar cells since 1954 under the banner of Hoffman Electronics corporation, and supplied the first solar cells to power a US satellite, Vaguard 1, in 1958.

Today, TECSTAR offers solar power systems, electro-mechanical and electro-magnetic assemblies, high speed data transfer-systems, and world-class controls design and development to the space and avionics industries. TECSTAR hardware has flown successfully on more than 1,000 satellites.
