Fuzzy-

Go with the two K70s, rather than the single K135. First, the two panels will give you some redundancy against breakage.... Second, the two smaller panels are less likely to be shaded at the same time than the one larger panel. Shadows across a panel can drastically drop its output—so the two smaller panels may actually have an overall higher output relative to the one larger panel.

Mispelt the name btw...should be Enertech.

55w panel is 900 * 550 (36'" * 22") 5.5 sq ft

80w panel is 1200 * 550 (47" * 22") 7 sq ft

Kyocera 70 is 800 * 650 (32" * 26") 5.75 sq ft

The 1200 panel is pushing it for space but we could handle two of the E55s or two of the K70ws. In fact the K70 would fit the available space(s) better than the EN55w. Twin panels would be mounted fore/aft on either side of bimini, alternatively we could possibly go for a single K135w across the stern.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
