Rigid and Flexible Solar Panels for Motorhome Power Kits
When considering solar panels for motorhome Power Kits, you have two fixed options: rigid or flexible.
Rigid solar panels are best for permanent installation on the roof of a motorhome or van. You can mount the fixed array with screws or adhesive. Rigid solar arrays are designed for permanent installations, but you can also find portable solar panels (reviewed above) with a similar flat, durable design.
Flexible solar panels, on the other hand, are made of thin-film photovoltaic cells deposited onto a flexible backing material. They’re lightweight and easy to mount onto curved surfaces. This makes flexible solar panels ideal for maximising sunlight capture on motorhomes and vans with curved roofs and irregular surfaces.
Combining rigid and flexible solar panels maximises available surface area, and pairing them with EcoFlow’s modular Power Kits provides a permanent off-grid power solution for motorhomes and vans. You can also add portable solar panels to set up wherever you park and a seamlessly compatible Smart Generator Dual Fuel to provide even more off-grid energy security.

What To Consider When Buying a Portable Solar Panel for a Motorhome
Power Output
Rated power output is an essential spec to consider when selecting portable solar panels for motorhome use. Rated power measures the maximum amount of electricity the panel can generate for your motorhome’s off-grid power system.
Many newcomers to solar power make the reasonable assumption that when a solar panel is rated for 400W, it will produce that amount of electricity whenever the sun shines…
The reality is more complicated.
Rated power is determined in a laboratory under Standard Test Conditions. It indicates the maximum amount of electricity a solar panel can produce under ideal circumstances, including:
- An optimal operating temperature of 25°C (77°F)
- Full solar noon sunshine (irradiance) of 1000 W/m2 (1 kW/m2)
(Basically, the irradiance used for testing is the equivalent of direct sunlight at the brightest time of day, completely free of obstructions like clouds or shade.) - Sea level air mass (AM) of 1.5 (1 sun)
Unsurprisingly, these conditions rarely exist in the real world.
Understanding rated power is crucial to ensuring a solar panel array meets your electricity consumption needs.
400W solar panels will never exceed +/- 400W of electricity generation, but on a very cloudy day or under significant shade, they may generate as little as 40% of their rated power.
EcoFlow’s rigid and portable solar panels offer an industry-leading efficiency rating of 23%. For planning purposes, it’s safe to assume that EcoFlow’s portable solar panels will produce about 75% of their rated power on average under real-world conditions.
So, on average, a 400W solar panel will produce 300W of electricity per hour.
Assuming 4-5 hours of peak sunlight, one 400W portable solar panel will produce about 1.6 to 2.4 kWh of electricity daily.
Portable Power Station for Energy Conversion and Storage
It’s important to remember that you can’t just purchase solar panels and charge electronics and appliances on your motorhome. Solar panels generate energy, but you need a portable power station or other balance of system to convert, manage, and store the DC electricity that solar panels gather as AC electricity.
When shopping for an off-grid power solution for your motorhome, you must consider not only the solar panel array’s rated power output but also your system’s solar charging and storage capacity.
Consider the RIVER 2 Pro Solar Generator from EcoFlow. The RIVER 2 Pro is a portable power station with a 768Wh storage capacity, 800W of AC electricity output (1600W of starting power with x-boost), and multiple charging options.
The RIVER 2 Pro Solar Generator with 220W Bifacial Portable Solar Panel can power all your personal devices and 80% of home appliances, and it’s lightweight and compact to take almost anywhere.
Almost…
At 17.2 lbs (7.8 kg), the RIVER Pro 2 might be a bit hefty to carry in a backpack on long hikes. And the bifacial solar panel adds another 20.9 lbs (9.5 kg). The entire setup weighs less than 40 pounds (18.14 kg), but you may not want to lug it up a mountain.
You also might not need that much power on a backpacking trip.
Luckily you have options. The RIVER 2 Solar Generator offers less electricity output and storage but can still run 99% of consumer electronics like smartphones, laptops, tablets, and more.
At 7.7 lbs (3.5 kg), you really CAN take it anywhere — even on foot.
At the other end of the spectrum, the DELTA Pro Solar Generator and EcoFlow’s Power Kits can turn your motorhome into a home on wheels, with all the comforts (and luxuries) electricity has to offer.
Whether camping in the forest, travelling in a motorhome or preparing for a blackout, the power station is as crucial as the solar panels in keeping you connected and comfortable.
PV Conversion Efficiency
The efficiency of your solar panels will affect the amount of power they can generate from the available sunlight. Look for solar panels with high conversion efficiency and low degradation rates to ensure that you get the most power possible from your solar panels over time.
At 23% efficiency, EcoFlow solar panels have a significantly higher conversion efficiency than the industry average.
Durability
Durability is a critical factor when selecting portable solar panels for motorhome use. The PV panels must be durable enough to withstand high winds, extreme temperatures, and exposure to rain and snow. They should also be resistant to scratches, dings, and other physical damage that will inevitably occur during transport or installation.
Choosing durable motorhome solar panels helps ensure that they last for many years and continue to provide reliable power for your motorhome. In the long run, better durability can reduce maintenance and replacement costs.
Some features to consider when selecting durable motorhome solar panels include a sturdy frame, weather-resistant materials, and high-quality construction.
Purchase PV panels specifically designed for outdoor use and tested for durability and performance under a wide range of conditions. Your panels will preferably have an IP68 waterproof rating like the EcoFlow portable solar panels mentioned above.
Size and Weight
For many motorhome owners, daily electricity consumption will exceed the amount of power that a single solar panel can deliver. If you need multiple PV panels, you may want to move toward a fixed array of rigid and flexible solar panels on your motorhome’s exterior.
Otherwise, you’ll be hauling multiple large panels in and out of your motorhome every time you move to the next campground.
Attaching several fixed panels to your motorhome’s roof allows you to disregard the size, weight, and effort involved in carrying and setting up multiple portable solar panels. By installing several 400W Rigid solar panels on your motorhome’s roof, you can generate power on the go without worrying about storing and setting up your solar panels every time you stop.
On the other hand, if your electricity needs are minimal, a single 160W or 220W bifacial portable solar panel is lightweight, compact — and easy to carry, store, and set up.
Compatibility
When purchasing portable solar panels, be sure that they are compatible with the rest of your system. PV panels typically have different output voltages and connectors. They may only be compatible with specific solar batteries or portable power stations. When possible, purchase your PV panels and balance of system from the same manufacturer to ensure compatibility.
Brand Reputation
Many solar panels have nearly-identical specifications and features, so it can be hard to sift through the duds to find a quality PV panel. Brand reputation is critical when picking a portable solar panel. The manufacturers that constantly provide high-quality products will inevitably receive great reviews and recognition.
Has the brand been featured in high-profile “Best Solar Products” lists? Have you heard from other solar enthusiasts that enjoy the brand’s products? Do your research before purchasing a panel from an unknown brand.
Price
While you may want to go big with an extensive solar array, this can be costly. Keep your budget in mind when deciding how much wattage you need from your portable solar panels.
Starting with one panel and adding more later is a safe solution. However, you must account for the solar input capacity of your portable power station or other balance of system. You can’t just keep adding solar panels if their power output exceeds what your system can handle.
