From the following "Space" article LINK

QUOTE
Spirit’s solar arrays currently produce about 650 watt hours while Opportunity’s generate up to 700 watt hours, Laubach said. A minimum of 300 watt hours is required for Spirit to function, though Opportunity can operate on slightly less, she added.


What is the reason for the lower power requirements of Oppy?

I thought the two rovers were identical.
