The cost of 8 of those puppies really adds up... about $2,400. Nice that they have been trouble free for 3 years. I have to keep reminding myself that the goal is to have enough solar so I don't end up buying and installing a genset. Gensets have their place but the hardware plus installation plus maintenance costs of them would be way fiercer than paying for panels.
I could see loosely linking groups of 3 of these edge to edge and moving them around and lashing them on deck to catch the sun and flip-flopping them into a stack for storage below. I keep coming back to the cockpit top. There are worries about chafe on the Sunbrella, etc.
