Thanks Nix

We're located at just under 2000" ASL and winters tend to be cold but quite sunny. The m=panel data sheets show a 0.48% temperature coefficient away from a standard data point at 25C. So in theory, at near to freezing point we will be seeing around 12% over generation. Of course the days are much shorter and the sun lower in the sky so we're not expecting miracles.

We also ordered the 125Ah Explorer batteries you recommended. They look awesome. My only experience with deep cycle discharge batteries is with a 60 AH unit that we liberated from some guys lamping illegally one nigh out on the field. That was 6 years ago. That battery is now being used by a friend for their emergency backup lighting, and its still going strong. We'll be mounting the batteries in the roof, immediately above a winter storage heater (gas vented to outside the house, assuming these batteries have an external vent tube?) The hope is that in this position they'll remain above freezing.

I'm looking forward to getting my hands on the new bits of kit, and am already thinking through requirements for a control panel to monitor status etc.
