Solar array

The solar array consists of 14 + 4 parallel connected solar panels with the sections of 196 x 196 mm in size made on the basis of silicon solar cells. Six single-side panels are mounted on the facets of the subsatellite at the distance of 10 mm from metallic surface, 12 panels are to be deployed in space. After deploying their axes have 100 deg angle with respect to subsatellite axis directed toward Sun. Four solar panels are reserved and switched to the system of subsatellite energy supply together with their DC/DC converter-inverter MPC after degradation of the panels initially switched on.

The current of the panel being orthogonal to the Sun direction is about 0.2 A at the operation voltage of 14 Volt. The maximum total power of the solar array at the nominal solar orientation is 36 W.
The solar array was made by NPO "Kvant", Moscow, Russia.
