If you mean VHB tape, that's all you need with a bit of sealant around the edge.

You can simply run a generous bead of SikaFlex on the bottom and press to the roof. No need for screws and more holes.

Thanks Lew,

Yes, I did get the 3M VHB tape and I also got DiCor from you guys too. The DiCor should work correct, that is what the Tech told me to use on the controller box and on the perimeter of Flexible Solar panels. I'll be using the VHB tape on the flexible solar panels to hold them down.

I know AM Solar uses Dicor, but I don't. SikaFlex has superior bonding properties and does not eventually dry and crack like Dicor, which has a high VOC content.

Just my preference.

So would the Homedepot Silkaflex work? I've included the link:
Sikaflex 10.1 fl. oz. White Construction Sealant-90618 - The Home Depot Just want to make sure I'm using the right stuff.

You want SikaFlex 221, not the construction grade.

So we can't find anyone locally that has SikaFlex 221 and we are in the middle of installing the panels right now. The only thing we can find is SikaFlex 715. Will that work???

New Flex Solar DIY Project

Nope. It's a self leveling sealant and not an adhesive sealant

That would probably work but will need a longer cure time, as it is a single component silane terminated polymer rather than a polyurethane like the 221.

OMG. It's done!

So, roughly two days and the solar project is done. The hubby (Ray) did most of the work with a little bit of assistance from a couple of friends. I did almost nothing (herniated disk precludes me from pretty much everything ). Oh, wait, I went on a wild goose chase in --did I say it was 100 freaking degree weather?-- to find the SikkaFlex 221. Drove a half an hour to the dealership, who confirmed they had it over the phone, only to be met with their chained up gate forty-five minutes before they were supposed to close!

So triple digit weather, perfect time for solar panel installation. The Airstream was like a sweat lodge. Hubby also sustained multiple blows about the head and upper body as he just can't seem to take my advice, "Be aware of your surroundings!" The tight quarters where the AS is parked is necessitating he wear a helmet just to walk around it. I mean, I put bright orange pool noodles on the the awning arms, and he STILL ran himself into them.

Everything seems to be working. There's more cleanup and a few details to tidy up tomorrow. We'll be going on an extended weekend trip not too far at a state park with primitive camp sites so I guess we'll get to see right away the fruits of our labor. Hopefully, there are enough fruits.

We finished the install and everything is working, what a bonus! Here is our list of items that we installed:

2 x 100watt Renogy® 100W Monocrystalline Bendable panels
Solar Boost 2512iX-HV
IPN-ProRemote
Temperature Compensation Sensor
Shunt controller
On/off Switch
30 amp circuit breaker
controller box
SikaFlex 221

We also removed the super loud refrigerator fan and replaced it with the SilenX EFX-12-15 Effizio Silent 120mm fan.

I have to say the 3m VHB tape is amazing, you really have to place it right the first time because it's not coming off. We did go with a 6# awg wire from the combiner box to controller box. The 6# was a Pain to connect to the controller panel, we also ran our connections to the battery. WE had to drill another hole to run the 6#, 4#, and the temperature sensor to the battery. I've been monitoring the system for the past 2 days and it appears to be working great!

Thank you everyone for advise and help. I'll post some pictures ASAP.

Ray

Ray,
I have been following your thread and considering doing the same thing. Can you give us an update on the performance of your system?

Hi Greg,

Since the install we have taken our AS out twice, the first was a 5 day trip to Fremont State Indian Park over the 4th of July weekend and this past weekend for a 3 day trip to the Jordanelle State Park. Both trips we didn't have hookups and we ran everything from our 2 group 24 Interstate batteries and charged our batteries using the 2 solar panels. We had no issues what so ever, we have 3 kids, 4 if you include me and they watched a movie, listened to music and had the lights on, we also had the fans on nonstop since it was about 90 degrees the whole time. According to the IP Monitor the batteries never went below 90% charge, and by the time we were done eating breakfast we were right at 100%. We are very happy with the performance and look of the flexible panels, even is low sunlight or filtered sunlight they appear to work fine. I've included a few pictures that show where we installed them on the roof and where we pulled them down behind the microwave. I did drill 2 small holes in the roof instead of one large hole, the 2 holes with the rubber gourmets it perfectly in the combiner box slot. Along with the VHB tape, putty that came with the black combiner box (AM Solar) and Sikaflex 221 on everything to make sure it was waterproof. I also, replaced the noisy refrigerator fan with the SilenX EFX-12-15 Effizio Silent 120mm Case Fan. I would recommend this easy replacement for everyone who has experienced the Jet engine OEM fan that comes with the AS.







I'll try an get a better picture from above so you can see everything on the roof.

Ray
