I'm also looking at Go Power. Let us know how they're performing in the heat. Any cupping, etc.

So far they are great. I just completed the installation, so I don't know about your cupping concerns yet. We are going to have GoPower! on the show on the 26th. Hopefully we can address some concerns. It would be great for anyone interested to call in their solar questions to theVAP voicemail line @ 707-533-4VAP. We can play them for GoPower!

I just put together a video on my solar flex installation. You can check it out here.

Do solar panels stop producing if any piece of the panel is in the shade?

Nice blog and great video . . .

Mr. Ambassador Tim:

You are doing a great job with your blog and video about installing the GoPower flexible solar panels on your 1960 Ambassador. Both are wonderfully informative. I look forward to hearing about your experiences with these solar panels while traveling and especially while boondocking. Thanks for sharing!

Maybe its just the AIRFORUMS app but I don't get sound for videos unless I go direct to the origin site or youtube.

Tim, I'm following your lead. Two GP Solar Flex panels. One 100 watt and one 30 watt. I have an 19 foot Bambi with limited roof space. I know it's a bit unproven, but I'm willing to give it a shot.
I too will use the 3M VHB tape. What was the width of the tape you used? Half inch? Three-quarter?

This is an interesting thread. Tim your video and instructions were great.
I don't know much (really nothing) about these systems but it looks to me that it might be the way to go. I don't boondocks much but it is always good to have some options as time moves forward.

Tim (or anyone else) - I have a 2013 Flying Cloud 28', in a perfect world how many panels would you put on and is this something I could do myself or should I have a dealer do it?

If the feeling is one can do this (DIY) what would I need for parts and were is the best place to buy the required items.

Thanks

Doug

Yes Tim, Thank you. I'm seriously considering this set up for my solar requirements. I'd be interested in your actual power generation over time. I also read some of the discussion with cooling (heat reduces the output) and I find this true with my home panels but I'm curious if air circulation around panels actually works better than the heat sink capability of the roof when panels are applied directly as you have done. Having the panels contacting the roof and shell might actually draw more heat away from the panels than air underneath can. Some heat conductive grease underneath would be even better but the chemicals may not react well with the panel base. Just thinking out loud.

Hey guys,

We did our big show on solar, its available here:

Episode 212: Go Solar! | The Vintage Airstream Podcast

I also did a video walk through of my flex solar install in case you might be interested.

GoPower! Solar Flex Installation Video | 1960 Airstream Ambassador Blog!

Thanks!

I haven't even seen it in person yet, but here's a photo of my SolarFlex installation. One 100 watt and two 30 panels. With limited room on our 19', it fit pretty well. Looks good, now I just hope it actually works!

Looks great! How about some more pics!

I didn't notice these past post questions before. Sorry I missed them. The 3M VHB tape I used was 4941. This is what Lewster recommended I remember it being 1/2" wide.

I let the tape setup for about a week, then went over the edges of the panels and mounting holes with sikaflex 221. Mostly to keep water from getting behind the panels and getting stuck there. Between the tape and sikaflex, these panel's aren't going anywhere. Even if I need them to!

Articfox - Get a couple of pieces of cardboard sized at 21"x42" and lay them in different configurations on your roof. Be mindful of items casting shadows when you do this step. You will quickly be able to determine the number of panels and their orientation this way. If you are mechanically inclined with hardware mounting and wiring, you should be fine doing it yourself.

Landrum - I have not tested how much a panel needs to be shaded to drastically reduce its output. I opted for more panels which cover the majority of my roof to make up for incidental shading. Just don't mount your panels butt up against a vent or air conditioner which will cast a shadow most of the day.

I conducted a very unscientific heat test on a 98 degree day we had a couple weeks ago.

For the base line, the most power I pulled from my 400w panels was about 20.5 amps when in full sun and running my microwave with the inverter. This was on a normal 80F day.

During the test, the outdoor temp in the shade was 98F. The panel surface on the solar read 159F with my IR temp gun (The photo shows 153F, but I did grab a 159F reading). I ran the inverter again and pulled around 18.5 amps from the panels.

So in full heat, the panels dropped in efficiency by 10%. For me, it's worth it for all the other benefits the flex panels offer.

The traditional panels would likely drop in efficiency as well. I'd like someone to post results of a similar real-world test.
