I have seen several of the solar panels used based on gallery shots and electrical layout discussions. What is the best currently available, most efficient, and largest output panel found so far that will successfully fit within the ~18"x30" companionway hood space? I have found 50 watt units from Sunpower, Renogy and the like that are a bit too square to fit in the space - such as 26x22" or 26x20". It looks like the next viable option drops down to 25 watt units. I will sort out the charge controller option once I've got the sun conversion taken care of.
Update: I found a 30 watt ETFE monocrystalline flexible panel that is 27"x14.5". Since that will likely provide 1.5 amp charge max,I went with a 10 amp mppt charge controller that is ip67 rated.
