Each of these panel types has a set of unique characteristics, pros, and cons. Below we cover everything you need to know.
The Different Types of RV Solar Panel
In general, there are three different types of RV solar panel: monocrystalline, polycrystalline, and amorphous panels. What are the differences between them? And, which one is best for you and your RV setup? Let’s take a closer look.
1: Monocrystalline RV Solar Panels
Monocrystalline solar panels are a type of photovoltaic solar panel made using a single crystal structure. The key component of these panels is monocrystalline silicon. They are known for their high efficiency in converting sunlight into electricity.
Their high efficiency and durability makes them one of the most popular types of solar panel for RV use. They are more expensive than the other types of solar panel on this list but they offer superior performance.
PROS
- High Efficiency
- Long Lifespan
- Durable Panels
- Space Effective
CONS
- High Cost
2: Polycrystalline RV Solar Panels
Polycrystalline solar panels are a cheaper alternative compared to monocrystalline panels. Although they don’t offer the same levels of performance and efficiency they provide sufficient power to run most RV electrical appliances.
Polycrystalline panels are made using multiple silicon crystal structures as opposed to the single crystal structure found in monocrystalline panels. They are a popular choice amongst camper van owners operating on a tighter budget.
PROS
- Cost Effective
- Reasonable Efficiency
CONS
- Require More Space
- Aesthetics (blue speckled appearance)
3: Amorphous RV Solar Panels
Amorphous solar panels are flexible. They do not use crystal structures like those found in polycrystalline and monocrystalline panels. This allows them to bend and change shape, an ideal quality for a solar panel being placed on a camper van or RV roof. They can contour the shape of the vehicle.
Amorphous RV solar panels are not as efficient as crystalline alternatives. They deliver less power. However, they are lightweight, flexible, and relatively cheap to purchase. Amorphous panels are a practical choice for RV applications, offering a trade-off between performance and adaptability.
PROS
- Flexibility
- Lightweight
CONS
- Lower Efficiency
- Silicon Degradation
4: Thin-Film Solar Panels
Thin-film RV solar panels are made by depositing a thin layer of semiconductor material onto a glass or flexible panel. These panels are valued for their lightweight and flexible characteristics, two important characteristics when it comes to choosing a solar power setup for a camper van.
They can be made using amorphous silicon, cadmium telluride, or copper indium gallium selenide as the semiconductor material. Thin film panels work well on curved roofs where flexibility is required. They allow the panel to hug the vehicle surface and deliver an aerodynamic fit.
PROS
- Flexibility
- Lightweight
- Low Cost
CONS
- Reduced Efficiency
- Shorter Lifespan
- Production Waste (cadmium telluride)
5: Foldable or Portable Solar Panels
Foldable or portable solar panels are compact, lightweight panels that can be packed up and transported when not in use. They differ from regular RV solar panels in that they are not permanently attached to the roof of the vehicle. They are designed for easy transport and on-the-go solar power.
Portable solar panels are designed to have foldable sections that allow them to collapse into a more manageable size for travel or storage. They are a very popular choice for RVs, camping, and hiking as they provide a convenient and portable source of solar power.
PROS
- Portable
- Convenient
- Lightweight
- Versatile
CONS
- Low Efficiency
- Fragile
- Cost
6: Rigid vs. Flexible Panels
When choosing a solar panel set-up for your RV you’ll have to choose between either a rigid or flexible solar panel system.
Rigid RV Solar Panels
Rigid solar panels are traditional photovoltaic panels mounted on a solid frame. They are made using crystalline silicon cells and tempered glass for protection. These panels are highly durable and come in a wide range of standard sizes.
KEY ADVANTAGES
- More Power
- Greater Efficiency
- Robust & Durable
Flexible RV Solar Panels
Flexible RV solar panels are made using thin-film technology (described above). They are sometimes referred to as flexible solar blankets or mats. These panels are lightweight and can bend and contour curved surfaces such as vehicle rooves.
KEY ADVANTAGES
- Flexibility
- Lightweight
7: High-Efficiency Solar Panels
These panels use advanced technologies to convert sunlight into electricity with increased efficiency. They are usually made using monocrystalline silicon cells and other advanced semiconductors. High-efficiency solar panels generate more electrical power for a given surface area compared to traditional solar panels.
They are a great choice for installations with limited space. If you have a shortage of roof space and need lots of power, these could be the option for you. However, as they use more advanced technologies, they tend to be more expensive but offer a good return on investment over time.
PROS
- Increased Efficiency
- Space Savings
- Power Even in Low Light
CONS
- Higher Cost
- Difficult Installation
- Complex Technology
8: All-in-One Solar Kits
An all-in-one RV solar kit is a complete contains all the components you need to generate solar power in your motor home. A solar panel is just one component of a solar power setup. To generate electricity and power devices you also need a charge controller, an inverter, and a battery.
RV Solar Panels
These panels are typically mounted on the roof. They capture sunlight and convert it to electricity.
Charge Controller
The charge controller sits between the solar panels and the battery. It ensures safe and effective charging of the battery.
Battery
Deep-cycle batteries are used to store the electrical energy. They are designed to accommodate deep charges and discharges.
Inverter
The inverter is used to convert the DC electrical power stored in the battery to AC. Most camper van appliances require AC power.
Which Type of RV Solar Panel is Best?
Which of these set-ups is best? Well, that depends on your needs, budget, vehicle constraints, and personal preferences.
Monocrystalline
This technology works best for individuals who want to maximize efficiency and are working with limited space. They are a good choice for RV and motorhomes with limited roof space.
Polycrystalline
These panels are a good choice if you are on a budget and want a cost-effective solution. They generate less power compared to monocrystalline panels, so you will need more panel space.
Amorphous & Thin-Film
These solar panels offer flexibility. They are a great choice for installations that are being placed on irregular surfaces. The panels can bend and contour curves and unusual shapes.
Foldable or Portable
These are the solar panels of choice for on-the-go power solutions. They can be folded and packed up when not in use. And, their light weight makes them ideal for hiking and camping trips.
High-Efficiency Panels
These should be used if you want to maximize the amount of electrical power generated. They are a more expensive option but offer excellent power output using limited space.
All-in-One Kits
These are the best option for individuals who require a complete solar power set-up. They contain all the devices you need to generate solar power – not just the panels.
