I was going to go your route with the drill-less mounts I think it is a very good option for anyone not wanting to drill into the roof.
But I have no regrets going with the flexible panels.... especially with Renogy's warranty and support. The Pro's just outweighed the Con's:
Pro's
- Very Light Weight
- Two Panels Producing up to 320 Watts (Fewer Panels Required)
- No Aerodynamic Resistance with Flush Mount to Roof
- Greater Resistance to Hail / Impact Damage
- Easy Installation w/ Eternabond or Dicor
- Same Warranty as Rigid Panels
Con's
- Longevity of Plastic vs. Glass / Aluminum
- More Expensive than Rigid Panels
- Less Heat Dissipation (I used Coroplast sheets under the panel for some ventilation)
I am also very impressed with the Renogy Rover MPPT Controller. It was more expensive than most but its capabilities are worth it. It will do a much better job maintaining the batteries than the stock WFCO Charger. I was going to upgrade by Charger but the Rover Equalization Mode will de-sulfate the plates and should help the batteries last longer so no real need to replace the Charger until it fails at some point.
