The Basic RV Solar Setup

You’ll need solar panels, batteries, and a power inverter to set up a stable RV solar system. The following chart best depicts the basic RV setup.

The RV solar panels collect solar energy from the sun and use it to recharge batteries. While solar panels and deep cycle batteries are enough to fulfill the basic RV power needs, some RVers want their rig to provide the same amenities as their homes.

The system needs to be complemented by additional solar power components to enjoy those amenities. These include:

Solar Charge Controller

The solar charge controller is a crucial component of the solar power system. It monitors the battery’s charging capacity and limits the flow of current when the battery reaches its full charging capacity. When the battery bank is full, the charge controller limits the current flow from the panels to the batteries.

There’re two main types of solar charge controllers. The standard Pulse Width Modulation (PWM) controllers limit the flow of current to a charged battery at an economical price. The Maximum Power Point Tracking (MPPT) controllers tend to be more expensive but offer a wide range of benefits.

PWM controllers. They are 30% more efficient and provide greater control over the charging of the batteries.

Solar Power Inverter and Converter

In some cases, it becomes necessary for RVers to convert different RV power types. For instance, if you need to operate an AC-powered appliance using solar energy, you’ll need an inverter to convert the 12-volt DC from the battery bank into 120V AC power.

Below, you can read more about the two RV power types and how they work.

RV Power Types

The electrical system of an RV can seem intricate until you get a basic understanding of how it works. RVs use two types of electric power to run electrical appliances. The power types include:

120-volts AC power

The 120-volts (or 220-volts in some countries) AC power system is typically used in our homes. It’s used for high-power consumption devices like microwaves, televisions, air conditioners, toasters, and other high-voltage appliances.

Most of the campgrounds and resorts provide you with an electrical pedestal or another appropriate receptacle for a ‘shore line’ connection. You can plug into the source using a heavy-duty power cord that comes with your RV. Depending on your RV, the cord can either be a 30-amp and 50-amp system. Smaller RVs, travel trailers, and pop-up campers usually use 30 amps, while larger RVs utilize the 50 amps hook-up.

12-volts DC power

A battery powers the 12-volt DC system, running all the basic RV components and devices. A fully charged battery will power the 12-volt equipment, including the furnace, water heater, most lighting, fans, and USB plugs in your RV. As long as your battery (or battery bank) is charged, you can use everything except the high-voltage appliances rated for AC power.

The DC power system is ideal for RVers who enjoy boondocking or prefer camping off the grid with no electric hookups. In that case, you can use solar panels to recharge your batteries and power your rig.

To assemble a solar system, you must connect the panels, batteries, controller, and inverter using a solar cable. While no wire is specifically designed for solar-powered systems, different cables are rated for specific uses.

There are two ways to wire a solar system.

  • Series wiring
  • Parallel wiring

Wiring Solar Panels in Series

When you connect the positive terminal of a panel to another panel’s negative terminal, you create a series connection. In series connections, the voltages of the panels add up while the amperage remains the same. For instance, if you make a series connection of four panels with a rated amperage of 5 amps and voltage of 12V, you’ll get an output of 48V and 5 amps.

Wiring Solar Panels in Parallel

With parallel wiring, the panel’s positive terminal is connected to the positive terminal of another panel. In a parallel connection, the system’s amperage increases while the voltage remains unchanged. The system will produce 20 amps at 12 volts for the above example.

The system fails if there’s an issue with a panel in a series connection. However, a defective panel does not impact the rest of the panels’ output in a parallel connection.

Types of Solar Panels

The amount of energy a panel harnesses depends on the panel’s cell type, maximum wattage, and structure. Below, we discuss the different types of solar panels based on:

  • Cell Type
  • Panel Structure
  • Portability

Types of Solar Panels Based on Cell Type

Several years of research and development have led to various types of solar panels. Solar cells can be divided into three categories based on the type of solar cell. Below, we take a closer look at each.

Monocrystalline solar panel

Monocrystalline panels are the most popular type of solar panels in the market today. The solar cells in these panels contain a single crystal of silicon, also called an ingot. A single monocrystalline panel contains either 60 or 72 solar cells with efficiencies ranging from 17% to over 21%.

Since the monocrystalline solar cell comprises a single silicon crystal, the electrons can flow easily through the cell. The free flow of electrons, in turn, makes the panel’s efficiency higher than other types of solar panels.

The higher efficiency and power rating are also responsible for the high price of monocrystalline solar panels.

Polycrystalline Solar Panel

Polycrystalline or multi-crystalline panels are popular among users who want to build a solar system on a budget. Their blue-speckled color distinguishes these panels with squares and uncut angles.

Polycrystalline panels are built by melting raw silicon, which is a cheaper and faster process than the one used for monocrystalline panels. This translates into a lower efficiency (15% to 17%), shorter lifespan, and lower cost.

Amorphous Silicon (A-Si) Solar Panel

The A-Si solar panels are thin film solar panels that use triple-layered technology. They are highly flexible and can handle higher temperatures. The main issue with amorphous solar panels is that they take up a lot of space, making them unsuitable for RV installations.

Thin film solar panels are cheaper than the mono- and polycrystalline counterparts, but they have a shorter lifespan and an efficiency rating of 10% to 13%.

Rigid vs. Fixed Solar Panel

Solar panels are either rigid or flexible, depending on the structure of the panel. Here is how the two differ from each other.

Rigid Solar Panel

Rigid solar panels are made with an aluminum frame protecting tempered glass and are the most commonly used panels. They are known for durability and can typically withstand extreme weather conditions, including rains, winds, and hail storms.

These panels are installed in sturdy brackets and can be angled for maximum solar exposure. Rigid RV solar panel is relatively heavy, and installing too many of them may create air drag and reduce fuel efficiency in the long run.

Flexible Solar Panel

Flexible solar panels are adaptable panels and weigh much less than rigid panels. They are ideal for curved surfaces, non-traditional RV shapes, campers, and light vehicles. Their incredibly low profile makes them the best option for a stealth solar system.

Flexible solar panels need secure installation; otherwise, the air drag may take them off the RVs’ roof. They are prone to scratching and, therefore, less durable than their rigid cousins.

Fixed/Mounted vs. Portable Solar Panels

As the name suggests, Fixed solar panels are permanently mounted to the RV’s roof. They must be mounted and connected only once, requiring little to no maintenance. Fixed panels are highly durable and can withstand some environmental beating.

Portable solar panels are a great first step for beginners in solar energy. These panels can be moved around and placed anywhere the sun is shining. A major advantage of portable solar panels is that they can be placed anywhere in the sun while you camp in the shade. As the portable panel harnesses solar energy, you can use a heavy-duty power cable to recharge your batteries.

What Type of Solar Panel is Best for RV?

Now that you’re familiar with the different types of solar panels, you may be wondering which type of panels can serve your RV best. You need to consider a few factors before selecting a solar system to answer this query.

How often do you go off-grid?

If you’re boondocking and regularly camping in areas with no electric hookups, we suggest you get mounted panels with a monocrystalline solar cell. You only have to install them once and never worry about their maintenance. Mounted solar systems are rigid and can handle various weather conditions and low-pressure water jets.

Do you want the convenience of home?

If you’re a full-time RVer, you may want to install fixed RV solar panels with a power inverter to convert the 12V DC power to 110V AC power. This will enable you to recharge all your AC-powered electronics while on the road.

How often do you’ve overcast days?

If you’re camping in locations with heavy cloud coverage, the good idea is to get solar panels that work well in low-light conditions. A portable solar panel is ideal for those who frequently park their RVs in the shade. You can easily transport and install it where the sun is shining.

Consider your RV’s roof.

A plain RV roof can accommodate almost all types of solar panels. However, you’ll be limited to flexible panels in case your vehicle has an uneven surface. They are lightweight but less efficient than rigid panels. A major issue with flexible panels is that they can be taken off by air drag unless you firmly install them.

Consider the expandability of the system.

If you plan to expand your RV solar system in the future, make sure to place and install your solar panels carefully. You may also need to avoid a solar kit because they usually limit the expansion option.

The best solar panel for an RV is the one that suits your specific needs. With these factors in mind, you can choose a suitable RV solar panel.

How Many Solar Panels Do I Need to Run an RV?

Before even considering installing solar panels on your RV or camper, you should figure out your everyday energy needs. Calculating your average power consumption combined with the wattage of individual panels and solar exposure are the major factors to consider when evaluating the required number of panels.

You can calculate your average power consumption by analyzing the energy required for each device. Here is a list that will give you an idea of the wattage drawn by different appliances.

Most RV solar panels generate around 100 to 400 watts of power. This means that if you have a 400-watt solar system in direct sunlight for 6 hours a day, it will generate (400-watt x 6 hours) 2,400 Wh of solar power each day.

If you want to operate the basic RV appliances (light bulbs, fans, water pump) and a few electronics like TV, modem, and laptop, then a 300-watt solar panel with 6 peak sun hours to charge a single 12V battery with 150Ah of battery capacity would suffice.

If you include energy-hungry appliances like a fridge and a microwave, you might want to add 1 or 2 100 Ah batteries and increase the total solar wattage to 400-600 watts.

These are the minimum requirements to keep the basic appliances up and running. When it comes to solar power, more is always better.

How Much Do RV Solar Panels Cost?

When installing solar panels on an RV or a camper, you often have two options. You can either purchase a solar panel kit that comes with the necessary equipment for the solar system. The kit’s cost starts from under $100 for basic RV solar applications and can reach up to several hundred or even thousands of dollars for heavy-duty setup.

You can also buy all the gear separately and connect them to power your electronics. The cost of such a system depends on the price of individual equipment. Below is a list of the hardware and a rough estimate of the cost for each gear.

  • Solar panel: $70 to $500+
  • Batteries: $100 to $1,200+
  • Charge controller: $15-$400
  • Solar adapter: $15-$50
  • Inverter or converter: $150-$350+
  • Mounting hardware: Less than $50

Smaller solar panels are incredibly affordable and can be found for less than $100. These panels can meet the basic RV energy needs (LED light bulbs, fans, etc.) but aren’t suitable for high-powered appliances. To run power-hungry devices, you can add a few hundred bucks and get one or two 100-Watt panels along with the mounting hardware.

If you’re living entirely off the grid or love boondocking for an extended period, then you’ll need to spend upwards of $1,000 on the panels and another $1,000 on the associated hardware. Most brands offer panel warranties of up to 25 years and additional warranties for the solar setup’s associated hardware.

With the enormous upfront cost, many RVers ask if solar panels for RVs are worth the investment. Let’s find out the answer!

Are Solar Panels for an RV worth it?

One of the biggest concerns when camping or boondocking is access to electric power. While some campgrounds have electric hookups, some of the most breathtaking locations either don’t provide access to power sources or limit their use. With solar power, you no longer need to worry about power as long as the sun shines.

Solar power is a popular option among RVers for many reasons. Below, we share some of them.

Clean energy

A major benefit of solar panels is that they produce clean energy. Since the RV solar panel system has no moving parts, it does not create any mechanical noise when producing energy.

No maintenance required

RV solar panels require little to no maintenance to generate electricity. You only need to install them in the sun’s direction and connect them to the batteries. They are lightweight and portable, which makes them ideal for camping or boondocking.

The cost of solar panels is constantly dropping.

A decade ago, a standard 6kW solar system’s cost was more than the average cost of an RV. But the cost of per watt solar energy has significantly plummeted in the last ten years. Thanks to the advancements in technology, solar panels and the associated hardware like controllers and inverters are witnessing a constant decline in prices.

While the upfront cost may still seem a lot initially, the investment will likely pay off in a few years. Based on these reasons, RV solar setup is definitely worth the investment.

Final Thoughts

Solar panels have gone from rarity to a nearly ubiquitous commodity within a decade. As the technological landscape is constantly improving, we can’t be sure what tomorrow may have in store for us. However, if you were to buy a solar kit or panel today, we highly recommend those listed above.

These solar panels and kits will make sure that you’ve enough power to feel comfortable while you’re on the road. They will give you peace of mind and make you experience the amenities of your home even when you’re away from it.

With a bit of solar knowledge and the necessary equipment at hand, you’ll be able to easily set up the system. However, if you’ve no prior experience with electricity, we advise you to consult an expert before messing around with any of the equipment.
