Running similar wattage on my shepherds hut setup and the 150/10 is genuinely solid for that scale. Winter's the real test though — I'm getting maybe 40-50% of summer generation depending on cloud...
Yeah, that's the trade-off isn't it. Frost looks stunning but plays absolute havoc with output. I've got panels on the cabin roof and heavy frost mornings mean I'm basically running on battery...
Been through this with my cabin setup. Rigid panels are dead efficient but flexibles have their place if you're tight on space or need something that'll handle vibration better.
Reckon it depends on your tolerance for problem-solving at 2am. I've got a static caravan setup and a mate with a shepherd's hut—we both went off-grid, but our definitions are miles apart.
For him...
Been through this myself — got a mixed batch of older Renogys for my static caravan setup three years back. You really need to know the panel history though.
Decent thread. Solar's the safer bet on a boat—panels are dead simple, no moving parts vibrating themselves loose, and you've got predictable output on decent days.
