I just installed two Solara fixed frame 140's on my boat
today. They are purposefully built marine panels
. Very robust junction box, fairly thick aluminum
framing, and so forth.
I replaced two CP140 flexible's that had lower output and took up too much space. The 140's from solara take up significantly less space. I think what many people are missing here is that - if you have non shaded or only partially shaded deck/bimini area or are willing to mount the panels
on the rails or stern so they tilt (I am not) then you can probably get buy with cheaper, less efficient panels. You basically add one panel to your panel army and you have more than made up for efficiency. However, for us the two panels on the bimini
were constantly being shaded by our boom and other things. By reducing the overall width of the panel area by almost a foot we will be able to gain a lot of time on those panels before they get shaded and when they do, the high efficiency will help them to keep producing.
Bruce Schwab and the team over at Coastal Climate Control are absolutely fantastic to work with and they really stand by their products.... so yeah, you pay a lot more but you are buying service
as a big part of that price
