We have had a few customers that have combined the advantages of the SunPower flexible solar panels (lower price, lightweight) to create a custom fixed frame panel - typically by creating an aluminum frame for the panels.
Here's a photo from a Gozzard 36, the owner didn't want to damage their bimini and preferred the aesthetics of his SunPower 170W panels being on a custom frame above the bimini.
And another from a customer with a larger Beneteau. They took the same approach and in effect created a 340W flex/fixed panel that is around half the weight of a more traditional fixed frame solar panel. They then installed 2 pairs of these for a total of 680W aboard - that's potentially up to around 225amp hours a day at 12V
Here's the two pairs of "340W" panels back up on the bimini before the canvas went back on.
