Re: [Electric Boats] Re: Ok solar experts...

Hi There Capt. Mike;

Thank you for showing your setup. I thought about the same thing, but I do not have a boat,

and I did not know how that would work. I appreciate your posts, and your blog.

Gabe;

PS: Merry Christmas to All !!!

I've beeen using two 48 volt Kaneka panels as part of my solar bimini for a few years now. I'm just starting to document the setup:

They do a good job keeping the EP bank topped up, even though I am not anal about have shadows on them. One day I will get around to looking at how much I power I am getting out of them. But, I know it's enough to keep the wind generator shutoff all day. It would be too bad if they stopped making them. The price, size and voltage were a good fit for my solar bimini and EP setup. I also have two 75 watt Poly-Crystalline panels for my 12 volt house bank which also keep things pretty well charged too.

I looked at Kaneka panels, but they are no longer making them

Eric,

The last price I saw was around $240 per panel... Comparing the Poly-Crystalline panel with the Amorphous panel the poly will always come out on top. The kicker is shading, the poly-crystalline panel will die with anything but minimal shading, the Amorphous will take a pretty heavy shade and still produce and with reduced sun angle the Amorphous will still with the production battle... all in all, I'm making the change to the Amorphous 48 volt panel.. putting them in series on my 3 boats gives me the amperages that I want, and I do a little work I can get them on a sun follow mount while at anchor..

Hi Dave,
he

I don't know what they cost (no price listed on the site that you provided) but the output is only 60W for a full square meter (10.7 square feet or 5.6W per sq ft). Not bad for thin film technology but the Sharp poly-crystalline 240W panels are only 1.6 sq meters (17.54 sq feet or 13.6W per sq ft), more than twice the output from the same area as the Kaneka panels.

But if one really needs the voltage, they might have to sacrifice the oveysrall wattage for the 48V panels.
