ISS-Reshetnev satellites to use lighter solar arrays

Information Satellite Systems – Reshetnev Company will equip its future satellites with more lightweight solar arrays.

The weight of solar arrays was reduced for more than 10 percent due to the use of a thinner Germanium substrate for triple-junction gallium arsenide solar cells. At the same time the efficiency of cells remains at a level of not less than 28.5 percent.

This new technology was developed by a Krasnodar-based Saturn company specifically for ISS-Reshetnev. Improved solar cells will be used in solar arrays of ISS-Reshetnev’s middle- and heavy-class satellites.

Reduced mass of solar arrays, one of the components of a satellite’s service subsystems, enables more payload instruments to be housed by satellites.
