How Does It Work

Solar panels usually have the following parts or components. You have the panel itself, a charge controller, batteries, and an inverter.

The solar panel is responsible for collecting and converting solar energy. Depending on its type, panels can receive an ample amount of solar energy for your RV’s needs. Once it’s collected, the panel’s photovoltaic cells then convert the solar energy into DC. For the top-tier results, it’s top-rated to use several solar panels for a faster charge.

Electricity then flows into the solar charge controller. Many users consider this as an essential part since it prevents your battery from overcharging.

When the battery is low, the controller sends an ample amount of current to replenish its charge. Once it’s full, the controller limits the amount of electricity flowing to your batteries to prevent it from overcharging. There are several types in the market: one- or two-stage controllers or the modern pulse width modulated controllers.

The third part is your battery, which stores electricity for later use. Common types include AGM batteries, gel batteries, and lithium batteries. Many users tend to purchase lithium batteries since they are the most efficient among the three.

How many batteries you need depends on your RV’s energy consumption. As such, you will need to ascertain how many appliances and gadgets you are planning to run.

Most devices cannot run on DC. As such, it needs to pass through an inverter that converts DC into AC power current. After this, the AC power current is then being used by your various gadgets and appliances.

What Are The Different Types Of RV Solar Panel

Due to their popularity, RV solar panels come in several sizes, styles, colors, and the like. As such, there are quite a several factors and categories they differ in. However, these are the most common differences.

In terms of the type of solar panel, there are usually three variants found in the market.

The first type is the monocrystalline solar panels, such as portable solar panels for RV battery charging, distinguished by its black coloring and wafer-like appearance. Made from pure silicone materials, these panels are said to be the most efficient in collecting and converting solar energy.

However, monocrystalline solar panels also tend to be the most expensive since they are made from pure silicon.

The next type is the polycrystalline solar panels. They sport a blue color and have rectangular-shaped cells. Unlike the monocrystalline variants, these types have a different manufacturing process. Thus, they are not made of pure silicon and cannot deliver the same power as that of the monocrystalline ones. However, these types are powerful.

Moreover, polycrystalline solar panels are quite ideal for more prominent applications since they are quite cheap.

The last type is the thin-film solar panel. Out of the three, these types are the least-efficient in terms of collecting and converting. It is because it has a lower amount of silicon and can only provide a 13% energy-efficiency rate.

However, they are also quite cheap due to their materials and are quite compact. They are ideal if you are just planning to power up a small number of devices and gadgets.

Aside from the type, solar panels also differ in terms of their flexibility. Rigid solar panels are quite common in both the market and in actual use. These types are known to be durable as they are from tempered glass.

On the downside, they are difficult to move and are not for curved surfaces.

The other type is the flexible solar panels. Compared to the first type, flexible solar panels are 80% lighter and can be easily be molded to curved surfaces. As such, they are ideal to use in specialty applications or when there are height-weight constraints.

However, unlike their counterparts, flexible solar panels are susceptible to damage. Hence, you need to take extra care when handling them.

Frequently Asked Questions

What is the price range of solar panels for RVs?

Solar panels for camper units and other RVs range from $600 to $2,000, with higher-end products costing up to $3000. While $1500 is usually the starting point for a decent kit, the price can vary drastically depending on the solar panel technology and accompanying accessories.

For example, an RV solar kit with inverter technology included might cost more than a solar panel-only product. Models with inverter and battery systems will be even more expensive.

So expect to pay roughly $3000 for a complete RV solar system with batteries, inverters, charge controllers, adaptor kits, tray cables, mounting hardware, and other components.

Polycrystalline solar panels are also more affordable than monocrystalline options. However, branding will also impact price. A leading brand might offer a polycrystalline solar panel that costs as much as a monocrystalline solar panel from an unknown brand.

Is a 400-watt solar panel enough for RV?

Yes, a 400-watt solar panel is sufficient for an off-grid RV solar system. It is also enough for boats and off-grid residential units, allowing families to run different appliances and devices without worrying about high electric bills.

You can also calculate how many watts you need from a solar system for RV to know if a 400-watt solar panel is enough.

First, determine how many watts each appliance or device needs to run, including average usage length and frequency. For example, a laptop uses 100 watts/hour. Do this for all gadgets you wish to power and calculate how much electricity you’ll consume in a month.

Second, learn the average peak sun hours in your location. For instance, Arizona enjoys seven to eight hours of complete sunshine, while Massachusetts only three. Multiply it by 30 or take the monthly average.

Suppose your daily solar power requirement is 2,000 watt-hours (Wh), and the average monthly peak sun hours is 150 hours. Multiplying 2,000 Wh by 30 days gives us 60,000 Wh. Dividing 60,000 Wh by 150 hours results in 400 watts. Hence, a 400-watt solar panel is enough for motorhome units with these parameters.

How much solar do I need for 30 amp and 50 amp RV?

A 100 watt solar panel is sufficient for a 12-volt, 30-amp RV electrical system, while 200 watts is enough for a 50-watt circuit. How do we know this? Let us break down the math for you.

A 100-watt photovoltaic panel connected to a 12-volt electrical system generates about 8.3 amperes per hour. This translates to 49.8 amperes (Amps=Watts/Volts).

However, solar panels aren’t always at their peak. They can only peak maximum output when the sun is at its highest, which is around noon. So realistically, you should expect an average of 6 amperes per hour. Again, as the sun’s intensity constantly changes throughout the day, you’ll typically get around 5 hours of sunlight.

Using the adjusted parameters (six amperes and five hours), we should get 30 amperes, justifying the 100-watt-for-30-amp rule. Doubling this figure gives us about 60 amps, approximating the requirements of a 50-amp RV system.

What are the most trusted 12v solar panels?

Solar panels are the top-tier way to help you charge your batteries and, at the same time, provide your RV with energy converted from the sun. It is a practical investment and can provide you with many benefits.

There are many solar panels on the market today, each promoting their advantages over the other. Buying one needs a lot of thought, and you must make sure that you will be getting your money’s worth when you are decided on getting one.

The top-quality 12v solar panels should be made to last. The overall design should be able not just to withstand the non-controllable factors like the wind, hail, and sand. More so, it should be made with materials that can absorb as much sun as possible. So long as there is sunlight, it should be collecting. At its best, it should also be designed to be waterproof and the glass resistant to scratches. The good ones are usually supported by an aluminum base frame that keeps the sun panels slightly raised off your RV’s roof for proper airflow.

The type of solar panel cell also plays a huge role. Monocrystalline panels are known to be more efficient. It takes less space, but it may cost you more. Polycrystalline is cheaper and a practical choice, especially if you are just new to the solar panel idea.

Your solar panel should also be lightweight. You need to consider the fact that it would be sitting on your roof for a long time. It should be weight friendly so as not to add unwanted weight but also to make installation easier.

Although rigid solar panels are established and efficient when it comes to energy conversion, flexible 12v solar panels are getting more hype because it can bend to shallow curves and are less likely to crack. Your needs should determine the choice between rigid and flexible.

How many solar panels do I need for my RV?

Just like the question, “how much solar power do I need for my RV,” you might want to know the number of panels you need. Getting solar panels for your RV is one efficient way to save on costs and still maintain power to your vehicle. Knowing the right number of solar panels to purchase and install to your RV is critical to maximizing its benefits.

The first thing you must consider here is the size of your RV and your daily power consumption so you would know how much power you need to generate. You must consider the number of people in your RV. These appliances need the power, your geographic location, among other things. In general, though, most solar panels in an ideal set up can produce 100 watts. Still, again, that is with a perfect setup.

Note that the weather, time of the day, temperature, and other factors can impact the amount of energy that your solar panel can generate, and you cannot have consistent results too as again; everything is dependent on natural factors. In general, most RVs travel with one to three panels (100 watts). This can generate roughly six amps/peak sun-hour on average or approximately about 30A hours daily.

To provide a rough estimation using an assumption of 50 amps-hour requirements to power an RV daily and an exposure to 6 hours of light that would produce an output of 32.58 amp per hour per day, we can safely conclude that two solar panels would be enough for your RV. Double solar panels can produce 65.16 amp-hours, so we meet the 50 amp per hour requirement plus a cushion for additional energy needs.

To better assist you, you can start with two solar panels and do a trial run and go from there. There are also reliable online calculators that you can refer to that can help you determine your average power consumption so you would know how much you need to generate.

How long do RV solar panels last?

What makes solar panels a significant investment is it pays off for itself. Solar panels for RVs can be expected to last you a good number of years. The average life years of solar panels is an impressive 25 to 30 years with this considering the normal wear and tear.

If you are very keen on ensuring that it is maintained and cleaned, you might even get 40 years of your solar panel. Of course, if it lasts you that long, expect that there might be some slight deterioration with its performance.

Solar panels, yes, can last you for the right amount of years, but they don’t last forever. Based on studies, solar panels don’t die the traditional way but experience a slow death that can be termed as degradation. This is the gradual decline in your solar panel’s ability to generate energy. Regardless of the years of service, if your solar panel is generating less than 80% of the energy, they were able to produce in the first three years of use, then solar panel installers would be recommending a replacement.

Uncontrollable factors like the temperature spectrum, humidity, and corrosion are also factors that can affect your solar panel’s longevity.

How to wire RV solar panels?

Wiring your solar panels can be done in two ways. It can be wired either in parallel or series. Panels wired parallel have all their positive wires into a single combiner that connects into the charged controller. All the negative wires are also allocated to a separate combiner.

The goal for parallel wiring is to sustain the voltage but increase the amperage going into the charge controller. In specific shade circumstances, the parallel is deemed the better option because if one of your panels is shaded. The other one is not, then you are not losing as much power since you are still receiving the full voltage from the sun. Note that parallel requires bigger wirings, combiners, and fusers.

Each of your solar panels should be fused at the combiner intersection in case a short happens in one. The wirings are needed to be bigger too because your objective is to increase the amps.

Series wiring, on the other hand, is where you connect the positive of one panel into the negative of another in a long series like Christmas lights. With a series of wiring, voltage is improved while at the same time maintain the amperage. This type of wiring is simpler and less expensive because it requires no wiring or fuses. In certain lighting conditions like overcast days, series wiring is deemed to be better.

Both are used almost equally, and each has their pros, so it would be top-tier to seek professional guidance when deciding on how to wire your solar panels. Although based on RV users, wiring in series is the most suitable way to do it. This wiring set up involves less complexity but with higher efficiency. The key for it to be successful and safe is to fuse everything securely and properly.

Do RV solar panels need to be grounded?

Solar panels in RVs and homes are top-rated recommended to be grounded. The frames of all your panels must be connected or at least linked with a bare ground wire or an equivalent to a mobile system. An essential requirement, all exposed metal components of a solar panel, including aluminum module frames, should be grounded.

The main reason why it is best to have your RV solar panels grounded is when there is a potential short circuit in the panels of the system; we avoid the possibility of shocking and electrocuting anyone who gets into contact with the frames. For an RV, car, truck, or any mobile system, the chassis of the vehicle is commonly used as the electrical ground.

To simplify, the chassis of your RV is linked to the negative pole of the automobile’s house battery. This is often termed to as ground. But since your RV will work without any physical connection to the earth, then it’s more appropriate to term it as a local ground or ground plane. This is the spot where all the DC negative terminals of your lights, battery, starter motor, radio, blower fan, and just about everything that runs from 12-volts DC in your RV returns energy to the battery or converter.

To be properly grounded, your RV chassis should have its EGC wire securely and properly connected to the service panel’s bonding point. The EGC or Equipment Grounding Conductor is what shields your RV from lightning strikes since it will guide the lightning find its way back to earth in a direct and shortest course that’s possible. Furthermore, it will also protect you and the RV from a possible short circuit in the wiring of your RV that could cause to shock the RV chassis.

How to use & install?

Getting solar panels to your RV system is doable but not as simple as just laying down panels on top of your system and expecting it to work already. There are other involved parts that are essential to make it work so you can start converting your collected solar energy to usable electricity. Installation can be a little tricky, so it would be best to get a professional to do it for you. But in a nutshell, it will involve the following process:

• Mounting the panels – this initial step will vary depending on your choice of the solar panel. Rigid panels would need to be fastened on the roof via screws. At the same time, flexible ones can also be mounted by screws or using strong adhesives. Note, though, that you must consider the material of your roof in determining which glue to use. Make sure that the panel is secure.
• Run the wirings – the next thing would be to set your power cable to run from the solar panels and down into the RV’s charge controller. There are a few choices in getting this done. The simplest and most common method is via the refrigerator vent. The central premise here is not needing to put in unnecessary holes if there are existing ones already? If your refrigerator vent is far from the battery compartment, you might need to consider running the wire through or at the plumbing pipe side. If you go this route though, make sure that you apply sealant around the holes. If all fails, drilling is the next top-tier option for you to run the wirings.
• Connecting to your charge controller – always best to select a mounting spot that is close to your batteries so you can reduce loss. Once you have determined your charge controller location, then you can already make the connections to the power wires from the fridge vent.
• Inverter installation – although purely optional, if you are planning to use your AC appliances like microwave or laptop, then you will need an inverter so the solar panels’ DC power can be converted to AC. The inverter should also be installed near your batteries. Connect the positive and negative wires to the inverter and link it to the RV’s electrical system.

How to care & clean?

The required caring and cleaning for your RV solar panels are low. It doesn’t require high-level maintenance so long as it is well designed and properly installed. The reason why is requiring low maintenance is that it doesn’t have any moving parts. There is also no fuel consumed, and filters are not needed. There is nothing to replace.

One of the care maintenance routines highly suggested to maintain its optimum functionality is to clean your solar panels occasionally. You can use a non-abrasive cleaner just to rid it from the accumulated dust and particles. Remove any stray leaves if there are any, as well as any bird droppings. While at it, you can check the fasteners, screws, and mounts used to ensure that they are tight and in the correct position. Although, as stated that there are no moving parts, vibrations are coming from the daily road trips, temperature expansion, and reduction can loosen up hardware.

Every month, it’s nice to check the battery too for any corrosions and spot-on clean away any detected ones. The batteries, as well as the wire connections, are very critical to your solar panel system.

Once a year, it would be good to do an overall check tracing the wirings and connections. It is again to ensure that there are no loose ends that can cause resistance or heat. If installations need to be replaced, promptly do so as wires are detrimental to the overall performance and output of your solar panel.

Where to buy?

These solar panels are available in many places. These include home depots, solar products’ shops, and home improvement stores. Online, you can also buy them from the websites of the manufacturers. Also, you can find them in online marketplaces, including eBay and Amazon. Nevertheless, compare your options well before buying a solar panel kit and check their features based on the size you need.

Conclusion

Installing the best RV solar panels will save you on cost in the end. It is why it pays off that you study your options well before buying a system or kit for your recreational vehicle. These solar panels are great for backup power, camping, and off-grid solutions. Before buying one, you should weigh your options based on the features and specifications you need. Get started in comparing using the buying guide earlier. Also, be aware of the things you should look for in a solar panel kit. Take effort and time to weigh the top picks and their features.
