About future energy availability, I made the following plot comparing last daily watt-hours (red points) with corresponding trend in previous martian year, obtained by shifting the date 670 Sol back:

There is a strange time shift between the two trends (50-100 sols) and last data seems almost 100 Whr below corresponding energy of previous year trend; anyway, if trend is confirmed, Oppy needs to reach a new winter site within November...

If you look at http://www.lpl.arizona.edu/~lemmon/mars-tau-b.html you'll see that we get basically the same peaks and troughs each year - but there's often a lag early or late depending on how the weather is doing. Regional dust storms I think can bring spikes forward or push them back.
