If you want to expand your solar setup to collect more sunlight and charge your batteries faster, this solar panel expansion will add more amperage to your charging output. This kit includes a single, flexible 190-watt solar panel with mounting hardware that connects to your existing Go Power system using the included MC4 branch connectors.


High-Efficiency, Monocrystalline Solar Panel

flexible solar cells

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 190 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 feet and 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.

Easy to install. Just plug and play.

Easy installation on the pop top roof of my campervan. Used six strips of 2" 3M VHB tape, with a Sikaflex sealant around the edges. Plugged in and immediately started charging the house batteries.

  • Can the Go-Power Solar Flex Eclipse System Charge 2 AGM Batteries to Run Small Appliances Off-Grid?
    Hi Mike, If you're going to be running your 12V fridge, cooling fans, and display off your dual AGM batteries; you can use the Go Power Solar Flex Eclipse Charging System part # GP67MR with the addition of another panel. The Go Power Solar Flex Eclipse Expansion Kit part # GP77MR will increase the systems watts from 190 watts to 380 watts which is better suited to keeping the fridge running as well as the other electronics. The average 12V compressor fridge uses 30-60 amp hours per day,...

  • Recommended Inverter and Solar Panel for RV
    For a 30-Amp service RV with the Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger, # PD4045KA installed, I recommend the 1,000 Watts - 12V Progressive Dynamics Pure Sine Wave Inverter w/ Transfer Switch & Remote, # PD94FR. I really like the build quality of the Progressive Dynamics products and this component has an integrated transfer switch that will automatically change from inverter to shore power when you hook up to a power pedestal at the campground. The fixed-mount...

  • How Many Solar Panels Can Hook Up To 30 Amp Go Power MPPT Solar Charge Controller
    The Go Power Solar Flex Eclipse Charging System with MPPT Solar Controller # GP67MR is a 30 amp controller. It will be 10 amps per panel so 3 panels would be the most you could hook up. You can get two of the # GP67MR and three additional panels # GP77MR. The other option would be to just buy the panels and use the # GP54FR which is a 60 amp controller. This is also capable of using a remote # GP34FR or Bluetooth dongle # GP94FR if you want to monitor the controller from your phone.

  • When Installing Multiple Go Power Solar Panels in Parallel, Does Each Panel Need its Own Fuse
    No, when adding additional panels like the Go Power Solar Flex Eclipse Expansion Kit # GP77MR in parallel, you do not need a fuse for each panel. Since the panels are connected in parallel and then go through the charge controller before reaching the fuse and battery bank, you just need the one 30 amp fuse. I have included a picture showing this.

  • Can the Go Power! Solar Flex Eclipse Be Mounted On the Side of a Trailer?
    So to answer a couple of your questions about the Go Power Solar Flex Eclipse Expansion Kit - 190 Watt Solar Panel # GP77MR: With your Super Pacific X1 having a canopy top only being a 1/2" less wide than the solar panel you have nothing to worry about it'll work just the same, Go Power just insists that since you're mounting horizontally, that they be installed at a minimum 10° angle to reduce dirt accumulation and soiling. Realistically, for the best sun-absorption you'd want to mount...
