Solar Panel Mounts

Would like to mount 6 panels to the roof of my class a holiday rambler. What would you recommend? Individual mounts or a rack system - I am somewhat concerned with body flex. The rv has a metal roof in sections joined with eternabond tape

Makes a difference what type of solar panels. Are they the heavy ones with glass , or the light weight "marine grade" panels built on aluminum backing plates ?

I like the lightweight panels which can be attached with 3m VHB double sided tape directly to the roof.

Welcome!!

Inexpensive Z mounts if installing flat. Tilt mounts can be simple manual units to a motorized rack that can even elevated over the AC units and other obstructions. I want with Z mounts because of inexpensive and inability to climb to the roof safely. To mitigate low winter sun angles and obstructions I have two additional panels made portable to set out when needed.

Here is attached a wrote up of my installation that may be useful to you.

We have a 185W 66 cell high voltage panel. I did not want to drill holes and imported six plastic mounts. I called and talked with a 3M engineer and he gave me the calculations for surface area needed on the mounts to successfully be able to use VHB tape and which specific VHB tape to use. Our roof is Filon I used the specified surface preparation and 3M cleaner. This has withstood wind speeds in excess of 120 MPH (75MPH, 40MPH head wind, BIG truck). I was VERY careful, the vision of a large solar panel sailing off the top of the trailer scared me a lot.

Grape Solar PhotoFlex 100-Watt Monocrystalline Solar Panel-GS-PHOTOFLEX-100W at The Home Depot
Just tape them down. High efficiency and weigh less than five pounds each. You pay for their advantages though.

Thanks VSheetz for the detailed info on your install. We will be upgrading our 150 watt system sometime next year. I will use your info and diagram as a guideline.

Tried and was unable to pull up the specs on that panel. Do you have them?

I wonder about their durability exposed to hail storms, weather, etc...

I know the durability is proven with the marine grade panels .....boaters all over the world run with these

Or their close competitors

They are so portable, there would be no need to leave them exposed to bad conditions. But they are pricey per watt. My panels are 315 watts and cost about $80 more each. You pay for that portability. But the entire product line seems overpriced to me.

Don't want to get into a price per watt discussion as it becomes quite a rat hole. But as for Grape being overpriced they sell a more conventional 100w panel - available via costco.com for $139 shipping included (if I recall correctly). This is a good price for a 100w panel.

Aurinco solar panels

Or their close competitors

SemiFlexible Non GlassĀ*Solar Panels : Products : Ganz Eco-Energy : CBC
In the rare event of storm damage one could replace a Grape Solar 100W Photo-Flex twice for the cost of one Aurinco 100W panel, which cost three times that of the Photo-Flex. 110 watts of Ganz panels will cost almost four times as much as one Grape Solar 100W Photo-Flex. I also know one can walk on the Grape Solar Photo-Flex without damage.

Boaters want to save money too, but I've never heard of one that uses Grape panels. There are boaters forums, and I've read lots of postings......never heard one guy using cheap stuff.....usually quality pays off in the end.
