An Intro to Solar Panels for RVs


First, solar panels are photovoltaic (PV) panels designed to convert sunlight into electricity. Typically mounted on the roof, these panels contain specialized cells that absorb sunlight and generate electrical current through built-in circuits. The electricity is then regulated by a charge controller before being stored in your battery bank. This stored energy powers 12V systems like lights, water pumps, and fans.


When paired with an inverter, a solar system can run 120V appliances a fridge, coffee maker, water heater, and computer. However, a panel’s effectiveness depends on sun exposure, battery capacity, and your daily energy demands. In general, higher power needs require larger batteries and more solar panels to keep up with demand.


Key Components of an RV Solar System

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (2)

Here are the important parts of an RV solar system:

  1. Solar Panels – Convert sunlight into electricity. Available in rigid, flexible, or portable designs.
  2. Charge Controller – Regulates power from the solar panels to prevent battery overcharging.
  3. Battery Bank – Stores solar energy for use when the sun isn’t shining. Lithium (LiFePO4) batteries offer the best performance, but AGM or flooded lead-acid are more affordable.
  4. Inverter – Converts 12V DC battery power into 120V AC to run household appliances like a microwave and coffee machine.
  5. Wiring & Fuses – Ensures proper power flow and protects the system from overloads or shorts. Proper gauge wiring is crucial to prevent energy loss, overheating, and fires.


Some RVers also invest in a solar generator—a portable power station that uses solar panels to generate electricity and store it in an internal battery. Unlike traditional gas-powered generators, solar generators are quiet, emission-free, and require no fuel,


Things to Know About RV Solar Panels


Here are some quick facts about solar power systems to clear up common misconceptions:

  • Solar panels still generate power in winter, rain, and cloudy weather, although efficiency is reduced in such conditions. They rely on light, not heat.
  • A solar panel rarely produces its full rated output. Under ideal conditions—clear skies and direct sunlight—a 100-watt panel might generate close to its maximum, but in real-world use, output is often 60-80 watts due to factors like angle, temperature, shading, and efficiency losses.
  • Not all solar panels are the same. Monocrystalline panels are more efficient and compact, while polycrystalline panels are more affordable but slightly less efficient. They both work well depending on budget and space.
  • The battery is the heart of an RV solar system, determining how much energy can be stored and used when sunlight isn’t available.
  • Solar panels are relatively affordable ($1 per watt), but the batteries—especially lithium—are the most expensive part of the system—around $1,000. Quality inverters are also costly—$1,000+.
  • Solar panels are measured in watts (W), which indicates their maximum power output under ideal conditions.
  • Batteries are rated in amp-hours (Ah) and watt-hours (Wh), which indicate their storage capacity.
  • Lithium (LiFePO4) batteries provide more usable capacity because they can be discharged deeper without damaging the battery. Unlike lead-acid batteries, which should only be discharged to 50% of their capacity.
  • Lithium batteries charge faster, weigh less, and last 3,000–5,000 cycles, compared to 300–500 cycles for lead-acid.
  • Solar alone may not be enough. Cloudy days and high-power demands may require backup from shore power, a generator, or alternator charging.
  • Reducing power consumption with LED lights, energy-efficient appliances, and mindful usage helps solar systems work more effectively.
  • An RV solar system cannot realistically run an RV air conditioner for extended periods without an extremely large battery bank and solar array.
  • The typical voltage output of an RV solar panel is 16 to 20 volts.
  • Solar panels last 20–35 years and maintain high efficiency over time, making used panels a viable and cost-effective option.


Types of RV Solar Panels

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (3)

Here are four types of camper solar panels:

  • Rigid Solar Panels – Durable, efficient, and typically mounted permanently on the RV roof. Best for long-term solar setups.
  • RV Flexible Solar Panels – Lightweight and bendable, making them ideal for curved surfaces. Less durable than rigid panels.
  • Tilting RV Solar Panels – Rigid panels mounted on brackets that can be angled for better sun exposure, especially in winter or low-angle sun conditions. They boost efficiency but require manual adjustment.
  • Portable Solar Panels for RVs (Suitcase Style) – Can be moved and angled toward the sun for maximum efficiency. They are often paired with a solar generator/power station. Great for boondocking or supplementing rooftop panels.


RV Solar Power Terms

Here’s a quick reference list for RV solar and electricity terms:

  • Watt (W) – It is the measure of electrical power used or produced by a device. It tells you how much energy something consumes or generates per second. Watts = Volts × Amps. Electrical appliances have a stamp that lists their power consumption in watts.
  • Volt (V) – Volts (V) measure electrical potential, or the force that pushes electricity through a circuit. It’s like water pressure in a hose—higher voltage means more force to move electrical current. Most RVs run on 12V DC for batteries and 120V AC for shore power. Volts (V) = Watts (W) ÷ Amps (A)
  • Amp (A) – Measures electrical current, or the amount of electricity flowing through a circuit. Think of it like the volume of water flowing through a hose—more amps mean more electricity moving at once. Amps (A) = Watts (W) ÷ Volts (V)
  • Amp-hours (Ah) – Measures how much current a battery can deliver over time. A 100Ah (amp-hour) battery has 100 amp-hours, meaning it can supply 1 amp for 100 hours, 10 amps for 10 hours, or 50 amps for 2 hours, depending on the load.
  • Watt-hours (Wh) – Measures total energy capacity (Wh = Ah × Voltage). For example, a 12V 100Ah battery holds 1,200Wh of energy.
  • Kilowatt-hour (kWh) 1 KWH = 1,000 Wh. Common unit for total energy usage.


How Much are RV Solar Panels

Here’s the cost of a complete RV solar system with batteries:

  • Solar Panels – Around $0.70–$1 per watt for new panels ($70 to $100 for a 100W panel or $280–$400 for a 400W panel). Used panels cost under $0.50 per watt.
  • Battery – Lithium (LiFePO4) batteries range from $500 to $1,000 per 100 amp hours, while AGM/lead-acid batteries cost $160 to $350 but have a shorter lifespan.
  • Charge Controller – MPPT (Maximum Power Point Tracking) controllers are more efficient and cost $100–$400, while PWM (Pulse Width Modulation) controllers are cheaper and less efficient, costing $20–$100.
  • Inverter – Costs vary by size and quality. A quality 2,000 to 3000-watt pure sine wave inverter costs over $1,000 to 2,000. Cheap Chinese models are around $200 to $400.
  • $300 for miscellaneous items like cables, connectors, fuses, panel mounts, etc
  • Labor – A technician typically charges an hourly rate of $130 to $170 or a flat fee of $300 to $1000 for installation. Costs may vary based on system complexity and location.
  • Total Cost – Most people spend between $1,000 for a small and inexpensive solar setup (300w of solar and 100Ah worth of lithium batteries) to $3,000+ for a powerful system with high-quality components (600w of solar and 200Ah Li batteries).


In contrast, a 3500 WH fuel generator costs between $400 and $1500.


Factors That Affect RV Solar Panel Efficiency

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (4)

Here are key factors affecting solar panel performance:

  1. Sunlight Exposure – More direct sunlight increases energy production, while shade significantly reduces efficiency.
  2. Panel Angle & Orientation – Proper tilt and direction maximize sun exposure.
  3. Shading – Trees, buildings, clouds, or even an RV’s AC unit casting shadows can decrease output.
  4. Dirt & Debris – Dust, pollen, bird droppings, tree sap, snow, and other buildup on panels can block sunlight.
  5. Temperature – High temperatures can actually decrease solar panel efficiency, as excessive heat reduces voltage output.
  6. Panel Type & Quality – Monocrystalline panels are generally more efficient than polycrystalline or thin-film options.
  7. Solar Charge Controller – A high-quality MPPT charge controller optimizes energy conversion better than a PWM controller.
  8. Battery Condition & Capacity – Old or insufficient batteries can limit how much solar energy can be stored and used.
  9. Wiring & Connections – Poor wiring, undersized cables, or loose connections can cause power loss.
  10. Geographic Location & Seasonality – Solar panels produce more power in sunnier regions and during longer daylight hours.


Pros and Cons of RV Solar Panels

What are the benefits and drawbacks of using solar panels in RVs:


Pros of Solar Power for RV

  • Free energy extraction from the sun.
  • No noise and vibration compared to traditional RV fuel generators.
  • Eco-friendly—no fumes, no noise disturbance, or use of fossil fuel.
  • Produces no emissions, ensuring clean air quality.
  • Minimal upkeep compared to generators.
  • Allows extended off-grid camping by reducing reliance on shore power.
  • Reduces electricity costs at metered long-term campsites.
  • Keeps batteries charged all the time, extending their lifespan.
  • Unlike a generator, they don’t have to be started and stopped.
  • Can be used to produce backup power at home when there’s a power outage.
  • Solar panels help keep the battery charged when your rig is being stored.
  • You can run remote security and automated systems when the RV is in an uncovered storage facility.
  • Fuel or LP savings if you also bring a generator camping.


Cons of an RV Solar Power

  • High initial cost of the system.
  • Solar energy depends on sunlight, meaning power availability fluctuates with weather, seasons, and shade.
  • Slow charging—compared to shore power, an alternator, or a generator, solar recharges batteries more slowly, especially in low sunlight.
  • Battery dependence. To store solar power for nighttime use, you need batteries, which add cost, weight, and maintenance needs.
  • Solar panels, mounting hardware, and batteries add weight to the RV, which can impact fuel efficiency and payload capacity.
  • Solar panels need roof space, which may be limited on smaller RVs or rigs with roof racks.
  • Clearance concern for tall RVs.
  • Not ideal for high-power RV appliances like air conditioners.
  • Not as effective in heavily forested areas, during long rainy periods, or in regions with limited winter sun.
  • Potential roof damage when drilling into the roof to mount the panels. If not installed properly, the holes can later cause leaks.
  • For maximum efficiency, you need to park in a sunny spot, which can make your RV uncomfortably hot in the summer.
  • Risk of hail damage to solar panels.


Verdict: Are Solar Panels Worth it on an RV?

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (5)

So, is solar power worth it for your RV? If you define worth as convenience, then solar is totally worth it. With solar power, you don’t have to worry about noise, fumes, vibration, fuel, and frequent maintenance. You have the freedom to park wherever you like and have power without having to hook up or run a generator.


Of course, there is a downside. Solar panels don’t work in all cases. For peace of mind when traveling in remote places, you need to complement the solar system with another power alternative, like an LP generator. This ensures that if it’s cloudy, snowing, or raining for days, you have backup power.


If your definition of “worth it” is strictly about saving money, then investing in an RV solar system may never truly pay for itself. The upfront cost of panels, batteries, inverters, and installation often outweighs any long-term savings on generator price and fuel. Unless you boondock frequently and avoid hookups entirely, the financial return is minimal.


Ultimately, the benefits of quiet, renewable power and the ability to live anywhere like you are plugged in justifies the cost for many travelers.


Who Should Consider Installing an RV Solar System?


Installing an RV solar system makes sense for several types of RVers:

  • Frequent boondockers.
  • Extended off-grid campers.
  • RVers with minimal power needs.
  • Eco-conscious travelers.
  • Full-time RVers.
  • Those bothered by generator noise.
  • RVers who frequent mild climates and rarely need to run the AC.
  • Those who chase fair weather.
  • Those who don’t mind camping without the AC or furnace.
  • Stealth campers who don’t want to draw attraction with a generator.
  • Those who very rarely use RV parks.
  • Long-term campers staying at sites with metered electricity.


Who Should Think Twice Before Installing an RV Solar System?


Setting up a solar power system for an RV doesn’t make sense for the following RVers:

  • RVers who use their campers just a couple of times a year.
  • You camp year-round in heavily wooded campsites or regions with frequent overcast skies.
  • Travelers who drive most days and have an alternator to recharge the batteries.
  • You heavily rely on air conditioning.
  • You only stay in developed RV parks with full hookups.
  • There are no public lands for boondocking in your region.
  • The generator that you already have is working for you.
  • You live and travel in areas prone to hail damage.

Keep in mind that some items draw a lot of power for just a few minutes, and others draw a small amount for a long period of time. Since most RV devices aren’t used simultaneously or for extended periods—and most people avoid running high-power appliances when relying on solar—you may need less battery capacity than the 253 Amp hours the table above suggests. Also, keep in mind there are some unseen electronics that may be running in the background, such as an inverter, when you’re using it. It may be a good idea if in strict conservation mode to turn these things off at night. You may also be able to put your refrigerator in night mode to conserve usage, if the option is available.


How To Calculate Your RV Power Usage for a Solar Setup

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (7)

How do I size my RV solar power needs? Here’s how to estimate the daily energy requirements of your RV so you can properly size the solar system:

    1. List Appliances (As shown in the table above): Make a list of all devices and appliances you’ll use, including their listed wattage and amps (check the spec sheet).
    2. Estimate Usage: Determine how many hours you’ll use each appliance per day.
    3. Calculate Power Consumption: Multiply the wattage of each appliance by the number of hours you’ll use it. That will give watt-hours (Wh) need per device. To get Amp hours, multiply amps by the hours you plan to use each device.
    4. Add Up Power Consumption: Sum the watt-hours from all devices to determine total daily energy consumption. Also, add the amp hours to figure out the total daily amp hours of all devices.
  • Size Your Battery Bank: Your battery should store at least one to two days’ worth of power. If your daily usage is 100Ah, a 200Ah lithium battery will have enough juice to last 2 days. In the table above, total daily usage is 253Ah, but actual needs may be lower. If you skip high-power appliances like the AC, induction cooktop, and radiant heater, a 200Ah lithium battery will be sufficient.


The most accurate way to measure your RV’s power usage is through real-life testing.
Start at sunset with fully charged batteries and disconnect from shore power, generators, and solar. Use your RV as you normally would—running lights, appliances, and electronics. Monitor battery levels periodically.


At the next sunset, check how much charge remains. The difference between full charge and the remaining battery capacity represents your daily power consumption. For even more precision, use a
battery monitor to track amp hours used. Repeat the test in different conditions to account for variations in weather, appliance use, and travel habits.


In addition, get an
electricity usage monitor (like a Kill A Watt meter). It measures the exact power consumption of 120V appliances in your RV. Plug the device into the meter, and it will display the wattage, voltage, and total energy used over time.


How to Size a Solar Power System for RV Camping

  1. Calculate How Much Battery You Need – Your battery should store one to two days’ worth of power to ensure reliable energy, especially during cloudy weather or shaded camping spots. To calculate the necessary battery capacity, get your total daily amp-hour (Ah) usage using our table, then select a battery bank with at least twice that capacity.
  1. Calculate Solar Panel Needs – Divide your Total Daily Watt-Hours (Wh) by the average peak sun hours in your location (typically 4-6 hours per day).
  • Example: If you use 1,200Wh/day and get 5 sun hours:
    1,200Wh ÷ 5 hours = 240W of solar panels needed (before factoring in inefficiencies).
  1. Account for Inefficiencies – Increase your solar panel wattage by 25-30% to compensate for cloudy days, inverter losses, and charging inefficiencies.
  1. Choose the Right Inverter – Choose an inverter that can handle the peak wattage of all the RV appliances and tools you want to run at the same time. For instance, a 3,000-watt inverter will be able to simultaneously handle one strong device, such as a 13.5 k BTU AC (2700 starting watts and 1350 running watts), as well as several other smaller electronics. If you’re not running powerful appliances like the AC, a smaller inverter will work.


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

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (8)

How many panels or batteries you need is based on how many amps of power you use during a 24-hour period. Generally, 400 watts of solar panels and 200 Ah lithium batteries is a good middle ground, as it’s enough to power basic RV appliances.


A good solar output rule of thumb is that a 100-watt panel will generate about 375 watt-hours per day, or 31.25 amp-hours. Using this rule, a 400-watt panel will generate 1500 watt-hours or 125 amp hours.


That’s enough power to run a standard fridge, TV, laptop, phones,
internet router, LED lights, fans, water pump, and microwave. However, it’s not enough for air conditioning. Even if you went with a bigger setup of 600 watts of solar panels and 600 amp hours of batteries, it will not power an AC for long.


If you plan to boondock for extended periods or camp in areas with limited sun exposure, consider a larger solar array and battery bank to maintain power independence. A setup with 600W of solar panels and a 400Ah lithium battery provides ample energy storage and faster recharging.


How Much Solar Power for RV Air Conditioner?

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (9)

Running an RV air conditioner solely on solar power for long durations is often impractical due to the massive battery bank and extensive solar panel setup required. However, let’s see how much solar you need to run an RV AC (13,500 BTU) for 12 hours a day:

Power Consumption of an RV Air Conditioner

  • Let’s assume a 13,500 BTU RV air conditioner draws 1,350 watts while running.
  • Its startup surge is 2,700 watts for a few seconds. Although having a unit with a factory installed or after-market soft-start may reduce this initial load.
  • However, an AC cycles on and off, with the AC running for 10-20 minutes before shutting off for 5-15 minutes, depending on outdoor temperature, insulation, thermostat settings, and AC efficiency.
  • So, the real-world consumption is often lower than the 1,350 running watts—typically 70% of the running wattage,
  • That means the actual use is 70% of 1,350 which is 945
  • To run an AC unit for 12 hours, assuming 945W consumption: 945W × 12 hours = 11,340Wh (11.3 kWh) per day.
  • Generally, solar is usually good for 6 hours per day. So you need to harvest 11,340Wh in 6 hours. That means you need 1,890 watts of output (11,340Wh ÷ 6).
  • It’s nearly impossible to fit 1,890 watts of solar panels on an RV roof. Most people don’t have that much RV roof space.
  • Further, to power the AC for 12 hours, you will need a massive bank of at least 900Ah of lithium batteries (11,340Wh ÷ 12V ​= 945Ah.)
  • The battery bank will be heavy. A single Li battery is around 30 pounds, so 9 batteries will weigh around 270 lbs. Lead acid will be twice heavier. Further, the cost of 9 Li batteries ($700 a piece), panels, inverter, and other equipment will easily exceed $8,000.

RV Solar System Tips

Are RV Solar Panels Worth it, Pros and Cons of RV Solar Power (11)

Here are some tips on RV camper solar systems:

  • Be aware that most of the RVs labeled as “pre-wired” or “solar-ready” have thin, cheap, and poorly done wiring that should be replaced.
  • Never let factory-installed solar power equipment direct your RV purchase decision. Choose the rig that you like, then add a properly sized system made from quality components based on how much power you’ll be using it.
  • Always read your RV manual for specific details on solar equipment and wiring. Manufacturers may have unique setups, limitations, or safety considerations that impact upgrades or modifications.
  • Always start by sizing your battery bank and inverter for your expected needs, then install the needed panels. With larger and better batteries, you have the building blocks to optimize and store the energy you will generate.
  • Size your solar panels 20-25% above your energy needs to compensate for cloudy days, inefficiencies, or unexpected usage.
  • Have a secondary power option—an LP generator or a solar generator.
  • Choose lithium batteries as they can be completely discharged, and maintain the same voltage as they are drawn down. With lead acid batteries, you can only utilize 50% of the capacity, plus they are twice heavier.
  • Get the Power Watchdog—a smart surge protector. It helps you monitor your RV’s electrical power (Volts, Amps, and Watts) in real-time from your phone.
  • For compact, lighter campers–consider flexible, lightweight roof panels because of the weight and height savings if you plan to store the RV in a standard home garage. Plus, you don’t have to worry about vehicle stability when driving or towing.
  • If mounting flexible RV solar panels, use 3M Dual Lock (industrial velcro), 3M double–sided tape, or silica flex adhesive.
  • Use self-leveling Dicor sealant on the screws after mounting permanent panels.
  • If you have limited roof space on your camper, add panels to your tow vehicle.
  • To conserve power, turn off the inverter when leaving for day trips and while sleeping at night. Inverters draw power even in standby mode.
  • If the climate were so adverse to need air conditioning, bring a generator or stay at a hookup campground.
  • Plan your travels around mild climates and seasons so you don’t need cooling or heating.
  • If you plan to run your RV’s air conditioner occasionally, install a Micro-Air EasyStart. It reduces the startup surge, allowing the AC to run on a smaller inverter or generator.
  • Get an inverter with a built-in transfer switch. It automatically switches the power source for your RV between external AC power (like shore power) and the power generated by the inverter (from the battery).
  • If you’re planning to boondock in forested areas, use satellite view to locate campsites with clearings to maximize solar charging.
  • If you boondock a lot and want to rely on solar alone, consider a tilting solar panel setup so you can always adjust your panels’ angle to optimize sun exposure. Don’t mount the panels too close together, as they may shade each other when tilted.
  • Be energy-conscious to maximize your solar system’s efficiency.
  • Use propane for your refrigerator to save energy.
  • When buying solar equipment, ensure you have a comprehensive warranty from the manufacturer in case of any defects or malfunctions.
  • If you have a limited budget, get used but working panels. 100 watts can be as low as $25 each.
  • Choose panels with the highest rated wattage for their size, as they occupy less roof space and collect more power.
  • Replace every single interior and porch light bulb with LED bulbs. And choose efficient appliances when making replacements.
  • Don’t run multiple heavy loads at once.
  • Clean panels regularly to remove dust, bird droppings, tree sap, and debris.
  • To fit panels around roof obstructions like the AC, skylight and vents, choose a mix of different sizes and shapes of solar panels. This allows optimal solar energy capture in limited roof spaces.
  • When dispersed camping, park your RV in a position that ensures the solar panels receive maximum sun exposure.
  • Watch Will Prowse’s videos on DIY RV solar setups.

RV solar payback period is around 8 to 12 years. How long it takes for an RV solar installation to be worth the Investment depends on the cost of the system, how often you camp off-grid, energy usage, panel efficiency, generator fuel costs, and electricity rates at campgrounds


What Will a 100 Watt Solar Panel Run?


A 100-watt solar panel generates about 375 Watt hours per day in good sunlight. Paired with a 100Ah battery, it can power 3 LED lights (45W for 5 hours), a laptop (225W for 3 hours), a phone, and even a mini fridge for a limited time.


What’s the Labor Costs for Installing RV Solar Panels?


The cost to install solar by an RV tech or shop is around $130 to $170 an hour. It may rise higher depending on the complexity of the system and the size of the solar panel array. Most RVers spend about ⅓ of the total price of solar equipment on labor.


What’s the Total Weight of an RV Solar System?


The weight of an RV solar setup with a 200Ah lithium battery and 400W of solar panels typically ranges between 100 and 150 pounds. A 200Ah lithium battery weighs around 50 pounds, while four 100W solar panels add around 60 pounds. A 40A–50A MPPT charge controller weighs about 4–8 pounds, and a 1,000W–2,000W inverter adds 15 to 30 pounds. Additional wiring, mounting brackets, and hardware contribute another 10–20 pounds.


Can You Use Home Solar Panels in RV?


Yes, you can technically use residential solar panels in an RV, but you need to use a special charge controller (MPPT type) that can handle the higher voltage produced by home solar panels.


How Long Do RV Solar Batteries Last?


RV solar battery lifespan depends on type and usage. Lithium batteries last 8–15 years or 2,000–5,000 cycles, while AGM and lead-acid batteries last 3–7 years with 300–1,000 cycles.


Can RV Solar Work in Bad Weather?


Yes, camper solar panels work in bad weather but at reduced efficiency. Clouds and rain lower output by 50–90%, while snow can block sunlight entirely if the panels are covered. That’s why having larger batteries is crucial—they store extra energy to keep your RV powered during low solar production periods.


Portable vs Roof Mounted RV Solar Panels, Which is Better?


Roof-mounted panels are convenient, require no setup, and are always charging. The downside is that they can’t be adjusted with ease. On the other hand, portable panels can be repositioned for maximum sunlight, but they require manual unpacking, setup, repacking, stowing, and storing. Further, the wires and connectors get worn out faster after hundreds of cycles. Plus, you have to worry about theft, rain, mud, and storage space.


Wrapping Up: Are RV Solar Panels Worth it?


RV solar panels are a great investment for off-grid camping, reducing reliance on generators and shore power. They provide quiet, renewable energy, saving money on fuel and campground fees over time. However, if you’re expecting a quick return on investment, solar alone may not justify the expense. The real value of solar lies in energy independence, quiet operation, and eco-friendliness.
