There are three at the moment, namely: PVR-P6 [=Photovoltaic Radiator Port Six]; PVR-S6 [=Photovoltaic Radiator Starboard Six]; PVR-S4 [=Photovoltaic Radiator Starboard Four]; Launched accordeon-like stowed (dimension stowed 1.9×3.5×0.6 meters), extended 13.670×3.405 meters (inclusive hinges). Maximum rejected thermal energy into the space is 14 kW (cooling rate). Each panel (3.405×1.880×0.102 meters) has doubled (ie. redundant) cryo loops with liquid ammonia. Launched together with ITS-P6 [=Integrated Truss Structure Port Six] and deployed after installation on ITS-Z1. As can be deduced from their designations, the PVR-S6 and PVR-S4 should be transferred to other truss segments in 2003. Mgr. Antonin Vitek, CSc.
