As someone who’s spent countless hours under the sun, installing and maintaining solar gear on RVs, I’ve learned one thing: a reliable solar setup transforms your boondocking experience. There’s nothing quite like setting up camp miles from the nearest outlet and still having full power at your fingertips. Solar panels bring freedom — freedom from generators, noisy hoses, and limits on where you can stay.
But with so many options out there, choosing the right solar panels or kits can feel overwhelming.
Every rig and lifestyle demands something slightly different, and the wrong choice can leave you stuck with disappointing performance or complicated installations.
In this post, I’ll walk you through some of the best RV solar panels and kits available today. I’ve worked hands-on with each of these units and factored in their quality, efficiency, ease of use, and durability. Whether you’re a weekend warrior or a full-time boondocker, this roundup should help you find your perfect fit.
The Go Power 10 Watt Solar Charging Kit is an excellent entry-level device for anyone who just wants to keep their batteries healthy without fussing over complicated setups. I’ve installed this many times for RV owners who primarily run their rigs on shore power but want a trickle charge to maintain their battery bank between trips.
With a maximum power output of 10 watts, this kit isn’t designed to power your appliances or rapidly charge batteries, but rather to provide a slow, steady charge. This slow charging prevents battery drain caused by parasitic loads—those small power draws from devices even when your rig is off. It’s especially helpful during storage or seasonal breaks when your RV is parked for an extended period.
Physically, the panel measures approximately 12 inches by 8 inches, making it compact enough to mount on a small area of the roof or sidewall. Its frame consists of powder-coated steel, which resists corrosion and adds durability for all-weather exposure. The wiring harness is pre-installed, and the integrated charge controller simplifies installation by preventing battery overcharging.
From a technical standpoint, the included 10-amp PWM (Pulse Width Modulation) charge controller supports 12V battery systems commonly found in RVs. It efficiently regulates voltage output by adjusting the power flow to the battery, thus preventing overvoltage situations. While it lacks the advanced features of MPPT controllers, at this wattage, the simpler PWM controller is perfectly adequate.
One tip from experience: pairing this kit with a quality deep-cycle AGM or flooded lead-acid battery will maximize battery lifespan. Lithium-ion users should be cautious, as this charger doesn't offer the specific charging profiles that lithium batteries require.
I recommend this kit to RV owners who want a no-fuss, low-cost solution to counter battery parasitic drain without the complexity of installing larger systems. It’s also great as a supplementary charger that works quietly in the background, extending battery life and reducing the need to use generators or shore power.
