My system continues to work great. I've been off the grid for about 2 years

Same with me. I don't usually get electric sites any more. Never run the batteries down.

Me too. Working perfectly, zero maintenance. I only bring the generator with me when I know I am going to be parked in full shade for an extended period...

Hi Dan,
Thanks for your posts a few years ago. That was what convinced me to do the installation as well.

Hey that's why we love this forum - I get so many great ideas here.

Cross your fingers for a Stanford victory over USC this weekend, and my Airstream (and it's unisolar panels) will be boondocking at the Rose Bowl over New Years...

Question:
Was scanning Ebay and found these...
http://www.ebay.com/itm/Uni-Solar-L-...YAAOSw8aNXGnXw

My question is how would you encapsulate them once you have tabbed and soldered the panel together?

keyair,
That seems like a lot of work to me. Why not use the 136 watt panels available on ebay from soldonweb. I installed 4 68 watt panels in series for about 65 volt output. That way I was able to use thinner wire.
They have worked great since I installed them.
Al

Thanks for the input Al.
I agree its a lot of work, but I need to custom build panels to suit the areas I have available...

Seems really expensive as well. Have you looked at some of the custom sizes from Amsolar, and I think either zamp or go power have smaller panels and flex panels.

I have read that the flex panels are not that reliable.....


Thx

Expensive?
I read the description states 7.3w/1.6v per cell, x 100, so that is 730w/160v for $200..
Most 100w panels are about $200 a pop, so I thought it was good value. Yes, I have to tab, encapsulate and wire, but I doubt I would be much more than $100/$150 total..
As stated, I have a very specific agenda for areas that I want to cover with solar, and they are curved. I dont want big, ugly aluminum framed slabs stuck on my rig!

Cool, I think I did math wrong. I thought it was three times the cost of a normal panel. Would love to see the finished work. Good luck


Thx

Those still need a supporting/cushioning backing and a trick little Z-fold in the tabbing then perfect EVA/Tedlar encapsulation, and some mar-guard glazed surface to protect the EVA, then have everything expand and contract with temperature change exactly the same... Run don't walk away from that project, want me to say it twice in CAPS?

https://www.amazon.com/dp/B01M4MXRDD <---43" x 12" 50w flex pv
https://www.amazon.com/dp/B01NBHT9NI <--- $150 100w flex pv

Best rigid panel --> 40.8 x 20.7 100w Eclipse (teeny!) https://www.amazon.com/dp/B01B3TEM1E

Maybe look for bulk deal on 30, 40, 50w flex panels - vendors on ebay & amazon both will usually offer discounts if you write explaining what you need...
They are getting better at pricing on the semi-flexible panels and are getting different size/configurations to market.

Like alot of you have posted about, I as well have a set of 136w panels I plan on installing once it warms up. The only thing I'm debating about though is do I shine up the roof before I install them, or just clean it. I plan on shining up my entire Airstream like a mirror ideally at some point this year. It's an older one that is pretty dull at the moment.

Can't wait for it to warm up!
