I've been waiting for flexible panels with the efficiency of the rigid ones. I could eliminate about 55# and a lot of windage from the bimini. Could Sobian Flex be the ones? They're not cheap.
I haven't seen flex at the same efficiency. I am working with a friend who is in the solar/alt energy commercial business. He observes also the solarflex film numbers are not good at all but is working on tents with very high area and high open circuit voltage and large area where the tents are to be covered with a fly made of solar flex films. We are talking about huge power and MPPT controllers. I wonder if a solar tarp we put out or hoist depending on conditions is a good idea.

That's what I've always thought, but the power output of the Sobian Flex panels is about the same as my similarly sized Kyoceras! So now I am wondering about the longevity of the flex panels. They're also more expensive.

With this new frame, we are mounting two Kyocera 135 watt panels (and a 205 watt on the davits).

Do you have a link? I did a google search and found "a big deal" about solar thin films at 5.5%. In my view, the target is around 18% now for thin film rigid. The flex at very low % has to be cheap cost per watts and be large enough to run up the mast or drape over the boom.

As a mechanical engineer who doesn't have a dodger or bimini (but I want one), I think you'll gain strength and stiffness with the increase in diameter, but the material doesn't matter much. Wall thickness does. Also, the sailrite kits' bows are split into sections, which I think dooms them to never be anywhere near as stiff as a one piece bow.

Re: Photos of Bimini Solar Panel Mounts

Here is the link to Solbian.

Their newest panels sport efficiencies of 17.5%. They're also expensive. The older models are a little less efficient but still comparable to most rigid panels, and cheaper. I found a couple of U.S. dealers by Googling (one of whom is a CF member). I have no experience with these panels, but I am definitely curious.

Re: Photos of Bimini Solar Panel Mounts

I just ordered these Sanyo high-voltage high-efficiency panels for the 48-volt electric motor I'm putting in for an excellent price: 195 watts, 16.8% efficient, $350. Shipping is brutal on solar panels. Note too the high voltage (Voc=68V) requires quite a charge controller.

Thin film solar is good for a sailboat with its shade tolerance and you-can-walk-on-it toughness, but poor because of the much lower efficiency, and therefore the need for more Watts capacity for an equal amount of energy production. In the terrestrial solar world, thin film is also not expected to last as long.

The sailrite frame is very strong. They say it is stronger than a one piece frame once it is put together. I believe them. Another good thing is when I tied the 1" bimini section rear frame to the 7/8" dodger frame via the bars it added rigidity as the rear frame helped descrease the side to side motion of the dodger too.

Impressive for flex film! Cell efficiency of 22.5 with panel efficiency of 14.44 (125 W panel) You could consider paving the deck with these. Did I miss pricing at this site or are they marked somewhere else?

Sorry to have to disagree. Also a PE. The material does matter. Youngs Modulus is way higher for SS over aluminum. If the OP is interested in stiff, SS and larger diameter will result in a much stronger and stiffer frame. For our solar support I wouldn't consider aluminum unless it started about 2" diamter.

There are prices here at Bruce Schwab. The newest panels are quite expensive. The older (but still reasonably efficient) panels are much less, if still more than rigid panels.

wow! those are pricey. I won't complain so about my 500 dollar Sanyo 225W panels.

Re: Photos of Bimini Solar Panel Mounts

And I thought the Aurinco panels were pricey at $786 for a 100 watter.

Re: Photos of Bimini Solar Panel Mounts

Picture of my first installation of Solbianflex panel with Solar Power 22.5% efficient Black crystals and zipper option for Bimini/Dodger mounting.



Bruce Schwab is here in Seattle at the Seattle Boat Show and I will let him know that are panels are being mentioned.

The 125 W panel is not avalible with the >22.5 eff. cell. Cell is used in the 50W long, 50W square and 100W long panels.
