Having experience with an alternative-energy refrigerator, I guess the one word I have to say is "pathetic". After that is no thank you.
Here's one more point that hasn't been mentioned in this thread. After going the maximal production, AC route rather than adhere to the thrifty DC route, besides just running the frig, I can run anything else. With the system that's designed to run the well-pump, anything else that gets thrown at it runs just fine. Need a cement mixer running all day, no problem! Wife wants to iron? I just told her as long as the sun is up, you can iron. She's happy.
