Which types of solar panels are included in solar panel kits?

Most RVers don’t really need an external power source, because camping sites usually offer a utility grid hookup. However, if you’re considering RVing or boondocking full-time, then you’re going to need a reliable energy source that will ensure you can use all appliances without any restrictions.

Take a look at the tips that can help you decide if you’re ready to RV full-time if you’re still having second thoughts about living a nomadic lifestyle. One of the things you’ll have to consider once you decide to spend most of your time on the road is the power system you’ll be using.

In order to do so, you will have to learn how to differentiate between types of panels you can find in different solar panel kits. Rigid or fixed solar panels are weather resistant which makes them a great choice if you’re searching for panels you can install on an RV’s roof.

The solar cells in rigid panels are protected by tempered glass that cannot be damaged by high and low temperatures or environmental factors. They come in an aluminum frame and they’re available in a broad range of sizes.

It is worth adding that the majority of solar panel kits contain one or more solar panels. Flexible solar panels don’t have a frame and their cells are protected by a plastic layer. As a result, they adjust to the surface they’re mounted on, which is the reason why they’re a popular choice for teardrop RV owners.

The protective plastic layer on flexible solar panels is prone to scratches, and they’re not as durable as rigid solar panels. However, almost all industry-leading brands offer flexible solar panel kits, so finding a model that can fit on your teardrop trailer shouldn’t be too hard.

Solar panel cell types

Best RV Solar Kits

Arguably, the most important feature you have to pay attention to while choosing a solar panel kit, are the cells that are located underneath the panel’s protective glass or plastic layer.

Most kits come with solar panels that have Monocrystalline, Polycrystalline, and Amorphous cells, but you might run into kits that include panels equipped with CdTe, HCVP, or CIGS cell types.

Even so, the majority of kits feature either monocrystalline or polycrystalline panels that are equally durable and efficient.

The panels equipped with monocrystalline cells aren’t bulky so it is unlikely that you’ll have issues fitting them on your RV’s roof or struggle to find storage for a portable version of these panels. Polycrystalline solar panels are a bit larger than their monocrystalline counterparts are, but they are more affordable.

Solar panels that utilize amorphous cells are bulky and don’t generate the same amount of energy as other types of panels, but they perform better in cloudy weather than any other type of solar panel cells.

Key components of a solar power system

Panels are just one component of a solar power kit, and you won’t be able to use the energy the panels gather without several other components. So, the system you install in your RV needs to have a controller that prevents the battery from overcharging as well as a couple of battery banks.

You’ll also need a solar power inverter, that will turn the DC electricity into usable AC electricity. Optionally, you can get a battery monitor, if you want to keep track of the battery’s remaining runtime.

Opting for a solar panel kit that contains all of these components may be a good idea if you’re setting up your first RV solar power system because it will spare you the trouble of looking for compatible parts.

RV solar panel kit installation process

RV owners who don’t want to install panels on the roof of their vehicle should opt for portable solar panel kits. The setup process is straightforward since you just have to position the panels facing the sun and connect them to a battery.

You have to keep rotating them as the sun moves along the horizon, and you’ll have to pack the panels when you no longer want to use them. Installing solar panels on the RV’s roof eliminates the need to go through the setup process every time you want to gather solar energy.

This option isn’t without its downsides, as it prevents you from adjusting the position of the panels so that they are always directly exposed to the sun. However, roof-mounted solar panels enable you to gather energy while driving.

Cost and maintenance requirements of RV solar panel kits

Best RV Solar Kits

Several factors can affect the cost of an RV solar power kit. For instance, mounting solar panels on RV’s roof will somewhat increase the installation costs of the entire system. The number of panels you have to get depends on your daily power consumption needs.

On average, a single 100W RV solar panel will produce between 300W and 450W per day, which should be enough to power low power consumption appliances. Most RVers choose kits that contain at least two panels in an effort to maximize the power output of their solar power system.

So, if you decide to purchase two solar panels for your RV you’ll have to spend between $200 and $1000, but you’ll have to factor in the price of batteries that can cost anywhere between $50 and $700, as well as all other accessories that aren’t included in a kit.

Once you’ve acquired all the components of the RV solar power system, you won’t have to spend money or time on maintaining it. Read our guide on how to budget for full-time RVing if you need assistance estimating the costs of living in an RV.

The advantages of RV solar panel kits

Minimal ecological footprint

Unlike generators that produce fumes that are harmful to the environment, solar panel kits harvest the energy without affecting the environment. In addition, they reduce the amount of money you have to spend on fuel.

Allows RVers to store energy

Getting multiple solar batteries will enable you to store energy on sunny days. It takes approximately 5 hours to charge a completely drained 12V battery, which means that you can fully charge at least two batteries in a day with a solar power system that contains two 100W panels.

Excellent durability

An average life expectancy of a solar panel kit is between 25 and 30 years, so by installing a solar power system in your RV you’re making a long-term investment that will save you a lot of money through the years.

Some components of the kit may have to be replaced more frequently as they are not as durable as solar panels.

The disadvantages of RV solar panel kits

Power collecting capabilities depend on weather conditions

Solar panels need direct sun exposure to harness the maximum amount of solar energy, and if they’re not correctly positioned or if a part of the panel is in the shade the kit will generate less power.

Factors worth considering while choosing RV solar panel kits

Best RV Solar Kits

Choosing an RV solar panel kit isn’t necessarily a complex process, but paying attention to the model’s features can help you find a kit that meets your demands.

Even a seemingly insignificant detail like the panel’s dimension can become important if you want to mount it on the RV’s roof. That’s why you have to go through the specifications of each component in the kit you’re interested in to find out if it’s suitable for the context in which you want to use it.

Let’s take a look at some of the most important factors you need to take into consideration while choosing a solar panel kit. Go through our guide to traveling alone in an RV if you’re planning to go on the road solo.

Power consumption needs

Estimate how much power you need for an entire day by checking the power consumption of all appliances in your RV. This will enable you to choose a solar panel kit that can generate enough power to run all equipment you use on a daily basis.

How often are you planning on using a solar panel kit?

The upfront cost of installing a solar power system in an RV can be too high if you’re using the vehicle for occasional camping trips. On the other hand, if you’re spending a lot of time on the road, getting several solar panels can turn out to be a great investment.

Panel’s cell type

Besides affecting the cost of a solar panel kit, cell types also affect its efficiency. You should choose a monocrystalline cell type if you want to use the kit even when the weather is partially cloudy.

Opting for the CIGS panel is a good choice if you want to maximize the power output of the solar power system you install on the roof of an RV.

Battery bank compatibility

Lead-acid and Lithium-ion are the two most common types of solar batteries. You must check if the solar panel kit is compatible with a particular type of battery bank. The durability of the batteries is yet another factor you have to consider since some battery types can’t last longer than five years.

Roof-mounted vs portable solar panel kits

Roof-mounted and portable solar panel kits have their advantages and disadvantages. The biggest downside of mounting a solar panel on the RV’s roof is the lack of rotation options, so they won’t receive the same amount of sunlight throughout the day.

On the other hand, portable solar panel kits are only a good option if you want to gather solar energy while you’re at a campsite.
