Default Thermogen efficiency

Guys,

Work out the required overall system efficiency to deliver 5 kWh of electricity 24/7, PLUS air con, PLUS hot water from 7 tube arrays measuring 2m * 2.4 m each in Brisbane (avg insolation 5.25 PSH).

Compare with published efficiencies for other solar thermal systems (eg. parabolic trough concentrators).

Then decide whether the kW vs kWh question is even worth quibbling about.
