Types Of Solar Panels For RVs

It’s important to know that there are different kinds of RV solar panels, each with its pros and cons. In general, there are 4 common types of solar panels for RV:

  • Thin-Film Solar Panels: Thin-film solar panels are lightweight and flexible. They are suitable for RV owners with curved roofs or those who want a more versatile installation option. These panels are less efficient than crystalline panels, which means you'll need more surface area to generate the same amount of power. Their flexibility allows for creative mounting solutions, and they are less prone to damage from impacts.

  • Portable Solar Panels: Portable solar panels are not permanently mounted on the RV. Instead, they are separate units that can be placed outside to maximize sun exposure. RVers can set them up at an optimal angle and distance from their vehicles to capture the most sunlight. These panels are ideal for those who want the flexibility to move the solar panels as needed.

  • Foldable Solar Panels: Foldable solar panels are designed for easy storage and portability. They usually come with built-in handles and fold into a compact size for transportation. When you reach your destination, simply unfold and set them up. They are convenient for RVers who want to save space inside their RVs.

  • Flexible Solar Panels: Flexible solar panels are similar to thin-film panels but more durable. They can be installed directly on the RV roof without the need for mounting brackets. They are lightweight and have a low-profile design, making them an excellent choice for RV owners who prefer a sleek, integrated look. These panels are known for their resistance to harsh weather conditions and impact.

The choice of solar panel type depends on various factors, including your budget, available space in your RV, aesthetic preferences, and performance expectations. Be sure to consider these factors when selecting the best solar panel for your RV.

Factors To Consider Before Choosing A Portable Solar Panel For RVs

POWEREPUBLIC 100W Portable Solar Panel

Actual Solar Output

When selecting portable solar panels for RVs, it's crucial to consider their rated power output. The rated power represents the maximum electricity a panel can generate for your off-grid power system, but it's determined under ideal laboratory conditions, which include:

  • An optimal operating temperature of 25°C (77°F)

  • Full solar noon sunshine with an irradiance of 1000 W/m2 (equivalent to direct sunlight at its brightest, without obstructions)

  • Sea level air mass (AM) of 1.5 (1 sun)

However, these ideal conditions are rarely present in the real world. In reality, a 200W solar panel will never exceed +/- 200W of electricity generation, but on cloudy days or in the presence of significant shade, it might produce as little as 40% of its rated power.

POWEREPUBLIC's portable solar panels boast a high-efficiency rating of 22%. This means that, on average, they will produce about 75% of their rated power under real-world conditions. Therefore, a 200W solar panel, on average, will yield 150W of actual solar input. So when selecting portable solar panels for RVs, it is important to know the actual solar input.

Pairing The Right-Sized Panel With POWEREPUBLIC Portable Power Stations For Your RV

It's important to note that solar panels alone won't directly charge your RV's electronics and appliances. You'll need a portable power station or a complete balance of the system to convert, manage, and store the DC electricity generated by the solar panels into usable AC electricity. Here are some options from POWEREPUBLIC for your RV needs:

Conversion Efficiency Of Portable Solar Panels

The efficiency of your solar panels significantly impacts their ability to effectively harness solar power for RV use. It is advisable to opt for solar panels with high conversion efficiency and minimal degradation rates to ensure optimal energy production over time. POWEREPUBLIC's portable solar panels excel with an impressive 22% efficiency, surpassing industry standards.

Durability

When selecting portable solar panels for your RV, durability is of paramount importance. These photovoltaic panels must demonstrate robustness to withstand harsh environmental conditions, including strong winds, extreme temperatures, and exposure to precipitation. Moreover, they should possess resistance to physical damage such as scratches and impacts that may occur during transportation and installation.

Choose RV solar panels featuring robust frames, weather-resistant materials, and top-notch construction. Opt for photovoltaic panels explicitly designed for outdoor applications and rigorously tested for their durability and performance across diverse scenarios. Prioritizing durability ensures that your solar panels will continue to provide a reliable power source for your RV for an extended period, potentially reducing long-term maintenance and replacement costs.

Size & Weight

For many RV owners, their daily electricity demands may exceed the output of a single solar panel. In such instances, when choosing portable solar panels for RVs, it may be wise to consider the installation of a fixed array comprising rigid or flexible solar panels on your RV's exterior. This approach eliminates the need to handle multiple large panels every time you relocate to a new campground.

By installing multiple 200W portable solar panels on your RV's roof, you can conveniently generate power while on the move without the burden of storing, transporting, and setting up multiple portable panels. Conversely, if your electricity requirements are modest, a single, lightweight, and compact 100W or 200W portable solar panel is easily managed, stored, and installed.

Compatibility

When choosing portable solar panels for RVs, it is essential to ensure their compatibility with the remainder of your system. Solar panels may have varying output voltages and connectors, and they might only work seamlessly with specific solar batteries or portable power stations. Where feasible, consider acquiring your solar panels and balance-of-system components from the same manufacturer to guarantee seamless compatibility.

Review & Reputation

Since many solar panels share similar specifications and features, brand review and reputation play a crucial role in your choice of a portable solar panel. Manufacturers renowned for consistently delivering high-quality products tend to garner positive reviews and industry recognition.

Budget

While the allure of a comprehensive solar array may be compelling, it is imperative to keep your budget in mind when determining your required wattage from portable solar panels. A prudent approach is to commence with a single panel and subsequently expand your setup as needed. However, it is imperative to account for the solar input capacity of your portable power station or balance-of-system components to prevent overloading your system with excessive power output.

Determining the Number of Solar Panels Required to Power Your RV

One of the most critical considerations when outfitting your RV with solar panels is determining how many panels you'll need to meet your electricity requirements. The number of necessary panels depends on your specific power usage, which, in turn, is influenced by your off-grid lifestyle.

Consider your typical off-grid activities. Are you a photographer who relies on heavy-duty cameras, drone equipment, and a laptop for editing? Perhaps you're a passionate foodie who enjoys cooking using electric hotplates and blenders. On the other hand, your needs might be more modest, limited to a few lights and keeping your smartphones charged.

To ascertain the ideal number of solar panels for your RV, start by keeping a journal of your power usage in watt-hours (Wh). Make a note of the wattage of each appliance you, your family, or travel companions use and the average daily usage duration in hours.

To calculate the daily power consumption for each appliance, multiply its wattage (W) by the number of hours (Hrs) it's in operation:

Wh = (W x Hrs)

Once you have these values, determine the total watt-hours of power you consume daily.

RV solar panels typically range from 100 to 400 watts of power. For example, a 200W solar panel charging for 5 hours during the daytime will convert sunlight into 1,000Wh (1 kWh) energy for your equipment daily. Doubling the number of panels doubles the watt-hours generated.

It's important to note that solar energy is well-suited for charging smaller appliances such as lights, phones, and even hotplates. However, powering larger devices like refrigerators for an entire day with solar energy may be challenging. Understanding your daily energy needs will guide you in selecting the appropriate number of portable solar for your RV during your off-grid adventures.
