Apparently a lot of suppliers have been cheating the manufacturers as demand was ramping up and prices pressured to go down.
Solbian panels are specifically built for marine use......

The bimini was a little loose when the picture was taken. However, the sag was from the weight of the panels on the canvas. I tightened subsequently, but it doesn't look a lot different and hasn't fluttered in up to 35 knots.

In this forum thread Lagoon 450 Modifications Dave from NZ shows pictures of his flexible solar installation on his bimini. And he got a pretty good price too.

Re: Flexible Solar Panel mounted directly on Sunbrella

Those are very interesting. Looks like they only charge one shipping price, even as you add more panels. The queston is do I want to be a quality test guinea pig.

Yup. Same thought crossed my mind. Or maybe just buy 2 extra for spares?

I notice their specs and their their marketing blurb closely imitates Solbians's.

Are we 100% sure that Solbians's are not also manufactured in China but "finished" in Italy? I ask because the photos of the factory on the Solbian web site look to be very low volume or an R&D lab.

I just bought and installed a 100-watt Solbian panel and I didn't see any "made in China" labels which would be required if they were. I will be getting another 100-watt Solbian panel for my Bimini installation at the end of this month.

Re: Flexible Solar Panel mounted directly on Sunbrella

I just ordered 2 of the 100watt Chinese made (with German cells) flex panels. They haven't arrived yet, so we'll see what they look like.

Did you purchase direct from them or had to go through somewhere else?

I did the contact through the AliExpress site. Had a bunch of messages back and forth to get what I wanted. They were responsive. Then when I went to purchase through AliExpress none of my credit cards would work on their site. Not sure if this was because it is China based or what. So I then used Paypal to pay them directly. I have not received the panels yet. They have a national 7-day holiday now and the panels are expected to ship on Oct 8th.

Re: Flexible Solar Panel mounted directly on Sunbrella

I have one of the 30W Shenzen panels, it works fine, but I cannot compare them to other panels since this is my first PV system....
The build quality looks shabby, there are some metal grommets in the corners which rust. The internal cell connectors seems to be covered with a white plastic strip which is visible through the plastic layer.
I am reluctant to bend it - afraid it will break..
