Does any one know what is the Nasa's space ships photovoltaic panels
efficiency compared with
the standard ones ?
much, much, much higher.
proven that Sunpower achieved a 20% panel efficiency for commercial use,
with GaAs cells NASA use for their satellites have a double efficiency,
ranging around 40% in the lab.
THis is mostly because of two factors: different technology used (much
more expensive) and environmental conditions: satellites orbiting around
our planet are about 240°C (say ~400F) below zero!! At such low
temperatures efficiencies of commercial panels would be rather high too!
