Not sure either. The solar panels we had were taking care of running costs but now we have a dedicated tortoise room, the ambient room temp is higher - meaning less time for the bulbs to be on and no night heat required in the winter either. So our running costs are still reduced to what perhaps they ought to be. I'll ask hubby to get his thinking cap on and see what he thinks. All a bit too mathematical for my poor old brain!
