It’s now September. The solar panel has kept the refrigerator running all season. On those rare days that the batteries were not at 100% by dusk, they were the next day. Most of these days have been since Labor Day. Seems there are more cloudy days and less hours of potential sunshine to boot. Soon, the fridge will have to be shutdown. All in all, results have been great. Today it is Sept 17. We had four cloudy days in a row, pretty good rain on one of them. No clouds today, and the batteries got to 100% around noon! Perhaps the fridge will make it to Octoberfest!
On a side note, it was comforting being able to check the boat from Alaska. Not only the battery status, but visually and live through the cameras (an app on my phone allows live view on cameras!).
