solar flex panel

The flexible panel includes silicon cells that are set between a laminated backsheet to withstand the elements. The panel is low profile and bends up to 30 degrees to suit the shape of your RV's roof, making them more aerodynamic than traditional solar panels. And in optimal sunlight conditions, the panel produces 100 watts per hour.

Easy Connection to Go Power Solar Charging Systems

mc4 connectors

This kit is compatible with several Go Power Solar Charging Systems (sold separately). However, the total amount of amps generated by the panels cannot exceed your solar controller's maximum amperage. The solar panel installs anywhere on your RV roof with included mounting hardware. To maximize sunlight collection, it is important to install the panel where it avoids shadows cast by objects, like an air conditioner or vent. The panel is wired in parallel to another panel using MC4 branch connectors.

This is perfect for RVs, boats, work trucks, long haul trailers, and sleeper cabs.The panel allows bending up to 30 degrees. It's a really nice, pliable construction. You can bend it, you can really maneuver it how you need for your particular application.

It's a lightweight, low profile design. This panel only weighs 2.9 pounds and measured three millimeters thick. Very simple installation, the expansion system easily installs next to the existing solar panel on your roof with the included screws.You do get a hardware pack.

  • Solor Equipment Recommendations for Jayco X23B With
    For solar panels I would start with the Go Power # 34272628 2-pack of 100 watt panels. (Total of 200 watts) In the future (or today) based on the available space on your roof you can easily daisy-chain one, two, or four more panels.

In most cases, something like the Go Power Retreat # 34272635 would be a good fit for you as long as you've got 2 batteries on your coach. I've linked some helpful videos and...
