The primary mission of these satellites is education, not amateur communications. As such, in daylight the primary payload is active at full power (the telemetry beacons, they are deafening when the transponder is off). On the weekends and at night, when the primary users otherwise do not need the satellite, they turn over the transponder to our use. I would actually guess that the transponder uses less overall power than the full power telemetry due to reduced duty cycle at lower power on the transponder, particularly while it flies over remote areas.
