If you are an energy-conscious RV owner, the Go Power Eco solar charging system provides clean, renewable power and a way to trickle charge your batteries while you are on the road. This kit comes with everything you need to charge your RV batteries with sunlight. Using a solar panel, this system collects solar energy to create DC power that passes through a solar controller to charge your RV batteries.


How It Works


Collecting Solar Power

eco panel

The charging process starts with the solar panel, which installs on the roof of your RV. When solar energy interacts with the silicon cells in the panel, it generates a flow of DC electrical current that charges your RV's batteries. Each of the monocrystalline cells is made from a single crystal of silicon, so the electrons that create the current have more space to move, making this panel more efficient than one with polycrystalline cells. And in optimal sunlight conditions, the panel produces 20 watts per hour.


eco panel close

The silicon cells are set between a cushioned backing material and tempered solar glass to withstand the elements. The glass has low-iron content to provide exceptional transparency, which ensures maximum sunlight collection. Finally, the panel is framed with anodized marine-grade aluminum to resist rust and corrosion.


Charging and Protecting RV Battery Bank

solar controller 10 amp

The solar controller prevents harmful overcharging by adjusting the power generated by the solar panel before it reaches your batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, this type of technology is a good fit for smaller systems with lower voltages.


Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, flooded/wet cell, and lithium batteries.


Charging Modes

  1. Bulk: This mode charges at the full rated load for a quicker recharge time. As the name suggests, this is where the bulk of the charging happens. It typically charges the battery to at least 80% capacity.
  2. Absorption: This mode provides controlled voltage to ensure a full charge. Once the battery reaches between 80% to 90% capacity, the absorption state will kick in and start charging at a regulated voltage. In each charging profile, this mode is set to last for 30 minutes after the bulk charge is completed.
  3. Float: Once the battery reaches full charge, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
  4. Equalization: On flooded/wet cell batteries, this mode activates to prevent stratification and sulfate buildup during extended float cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.

The backlit, digital display acts as an information center for your solar panel output. It shows the charging current, battery voltage, and battery state of charge. It also allows you to input your battery type and choose a charging profile. Additionally, a built-in USB port on the front of the controller provides a convenient outlet to charge your cell phone or tablet.


Lastly, the controller includes several built-in safety features to help protect your equipment. The charging process will shut down if the controller starts to overheat and when an overcurrent is detected. Also, if the battery or solar panel is wired incorrectly, it activates a reverse polarity alarm.


How It Installs

eco 20 how it installs

The system includes a 20-watt solar panel, a 10-amp PWM solar controller, MC4 cables, and all the necessary installation hardware.


  1. Solar Panel: 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 uses MC4 cables to connect to the solar controller. These cables can enter the RV through the refrigerator vent or using a Go Power cable entry plate (sold separately). The cable entry plate provides a covered housing and uses a quick connect setup for the MC4 cables.
  2. Solar Controller: The solar controller flush-mounts to a wall inside your RV. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the terminals on the controller. You can also install a fuse or circuit breaker (sold separately) up to 10 amps between the solar controller and battery for additional current protection.

Note: This kit may require more wiring and additional parts depending on your RV setup.

Hey! This little solar panel kit was exactly what I needed. I put together a bicycle trailer for my upcoming recumbent tricycle tour (this Spring). This little 20 watt panel will help me keep my battery charged during the ride.

Product is sturdy and well constructed. Coupled with a solar charger/boost controller this panel delivers all the power I need. Glad I bought.





by:

I purchased this to install in an enclosed trailer, so I can load and unload my side by side. The instructions were straight forward and I didn’t have any issues.



by:

Nice quality. Would have been nice if the roof entry was included. Be sure to order it if you are doing a through the roof installation.

The solar system has done a great job keeping my car trailer battery charged. It is a big 1,000 amp-hr battery that powers the lights, load winch and electric trailer jack. Even after a month parked, the battery is fully charged and ready to go. Nice!



by:

Perfect solution to fix a constant low battery condition after storing my fifth wheel for any extended period of time. Super simple install with clear and accurate instructions. Highly recommend this product!

Awesome product! Charges my trailer winch battery faster than anticipated. Control module shows battery's charge percentage and charge rate which is very useful

Great products and great people. When riding hours with my girlfriends etrailer and their good self help articles are fondly described. This is our go to place for horse living quarters products.

Product was easy to install and smaller than the factory product It was cloudy and raining yesterday so I didn’t get a chance to see if it operates but I’m sure it will



by:

The install was simple and appears to be working!



by:

I installed this panel on the bow railing of our 30’ sailboat about 1 year ago to keep the 105 Amp Hour deep cycle house battery topped as the boat sits on her slip all the time. And so far it has done an excellent job, battery shows full charge any time we take the boat out. I did use a small marine grade charge controller (bought elsewhere) for piece of mind as the panel can produce peak voltage higher than the recommended charge of the Gel type battery I have connected. Good panel served us well for our need.



by:

I was under the mistaken idea that it came with a standard Furion male plug. It doesn't come with any plug on the output end. However, the unit appears very well made and easy to mount.



by:

works great for my car trailer charges the battery for the winch



by:

Prior to installing this solar panel my battery would drain while my trailer sat idle. I added an additional battery and then installed this solar panel and now it does not drain from parasitic draw while sitting and not being used. I highly recommend this item or larger if dry camping.



by:

Works like a champ to keep my RV batteries topped off while in storage. This along with a cheap solar charge controller and your set.

  • Solar Kit for RV Roof For Maintenance Charge for Group 24/27 Batteries
    Group 24 batteries are between 70 and 85 amp hour batteries and Group 27 are between 85 and 105 amp hour batteries. A maintenance charge on a battery would only require a couple amps to keep the batteries topped off so a 20 watt kit like the # 34273837 would easily keep the battery topped off. This would provide 1.65 amps to the battery. If you think the battery will be depleted at any point before storage a higher rated charger would do a better job bringing the battery back from this...
