Re: Solbian Solar Panels

Tartansail,

I am interested in using the Solbian panels. Would you mind posting a picture of the install if you have one?

Thanks!

Here are a few pictures. Recognize that the optimal installation wouldn't cross the central bow. I would not have been able to install two panels in that case. At some point I may add lightweight backing to the panel where it crosses the bow though I didn't see any movement last season during some pretty nasty squalls.

The wiring was run through the frame of the bimini with disconnects at top and bottom. Each panel is connected to its own Genasun controller

As an aside, we turned the A-B refrigeration on when the boat was launched in May and never turned it off until hauling in October. The 2X125 watt panels kept the 4X235Ah 6V batteries charged. The cold fridge and beer kept the admiral and captain very happy.

Re: Solbian Solar Panels

David,

Nice pics. Thanks for posting them.

Do you know how many amps you are getting from these on average?

I'm didn't monitor carefully enough to be certain. I estimate that we normally started the day with a deficit of about 80-100Ah (anchor light, cabin lights, fans and fridge). During summer months in New England, the batteries were typically in float mode around midday.

I recently bought 4-50 watt panels from Aurinco for $1800 making a bank of 200 watt. They are simi-flexible, but mostly they are very thin and have a non-skid surface meaning you can walk on them. Mine will be adhered to the cabin top.

Re: Solbian Solar Panels

Wow...that's pretty good. We typically use the same amp hours so that should work well for us.

Thanks again, very helpful.

Solbian Solar Panels

I purchased 520 watts of solar off ebay, (2) used 110w Kyocera standard panels and (6) 50w Chinese made flexible panels. I fixed 4 of the flexible panels directly to the bimini using convertible top snaps. Also put 2 panels on the bow. The flexible panels can all come off in seconds. I have them all wired in parallel to a combiner box and then to a 25amp charger. I hope to update the controller to an mppt 40 amp soon. I'll do an update in a few months to see how they held up.Click image for larger version

Re: Solbian Solar Panels

I know nothing about solar so I want to make sure I'm doing my math right. If you have 2x 100w panels then you should theoretically be getting 66 amp hours of power per day?

My math is 200watts divided 12volts = 16.66 amps

16.66 amps x 4 hours of optimal out put during the day is 66.666 amps per day.

Is this correct?

Re: Solbian Solar Panels

Basically, yes.
Ohm's law: E=I*R E*I=Watt

http://www.robotroom.com/Calculators...alculator.aspx

You'll probably get more than 4 good hours because of panel construction. Also, keep in mind sail shading and heel angle so you won't get full output. You probably want to do a daytime calc, then multiply by .75 or so.

Your output numbers look right, but we get a lot more than 4 hours of charging during May-September in New England (42 degrees North). I don't monitor closely, but I estimate that the panels are producing meaningful current for all but a couple of hours at each end of the day.

Good to know, thank you. I figured it would be more than 4 hours but wanted to be conservative in my estimate. I mainly ask because I didn't realize or believe that solar could put out that much power in that size foot print.

Re: Solbian Solar Panels

I've been logging Solar Production (WattHours in a 24 hr period)/Rated Panel Watts). I'd be interested if others are doing a similar analysis. Rough numbers show that a 100 watt panel will give about 25amps into a half charged battery in 24hr of average Florida Sun (less than optimum for the reasons such as shade, heat, etc that others have noted). I've seen more from SunPower and other high efficiency panels. Unshaded panels, MPPT Controllers, big wires, etc all help...

Re: Solbian Solar Panels

I'm planning to install a couple of flexible panels to a bimini on a yacht in St Martin in the Caribbean.
Can anyone point to a dealer in that area please or do I need to ship them in? I'm in Australia.
Cheers
Drew

We ship Solbian to the Caribbean all the time (from Maine via FedEx). Or you could get them in OZ from Geoff at Solarfuture.com
