Hi David, > > Why are you so much against using a battery? > Batteries need to be replaced. Checked for cheap caps on ebay and found approx AU$50.00 for 1.5 farrad. This is a guess as it still a few hours to go. And there is something about cooling my beer down (not that I am a beer drinker) for *free* (minus initial cost of fridge, solar panel, cap and beer and their wear and tear). And the way I figure it, it seems to be a perfect match as there are all those lovely power producing daylight hours way before the first can gets cracked.
