Freedom from hookups, generators, and campground fees is closer than you think — and a well-designed RV solar power system is the key to getting there. SolarReviews has been helping homeowners and RV owners navigate renewable energy decisions for years, and the guidance in this article draws on that deep well of expertise to help you make the right call for your rig.

Whether you’re a weekend warrior or a full-time lifer on the road, solar power transforms the RV experience. You’re no longer tethered to campgrounds with electrical hookups or woken up by the drone of a gas generator. The sun does the heavy lifting, quietly and consistently, every single day you’re out there.

Your RV Doesn’t Need Shore Power to Stay Fully Charged

Most RV owners are surprised to learn just how capable a properly sized solar system really is. A 400-watt setup can comfortably handle lighting, phone and laptop charging, a 12V refrigerator, a water pump, and even a small TV — all without ever plugging into shore power. Once you understand how the math works, the whole thing clicks into place.

Why Solar Beats Generators and Campground Hookups

Generators are loud, burn fuel, require maintenance, and many campgrounds restrict their use during quiet hours. Shore power hookups limit where you can camp and often come with daily fees that add up fast. Solar, on the other hand, is silent, free to run after the initial investment, and available anywhere the sun shines. There’s no fuel to carry, no oil to change, and no noise complaints from your neighbors two sites over.

How Much Solar Power Does an RV Actually Need?

On average, most RV setups require between 200 and 600 watts of solar power to keep things running comfortably. A minimalist setup with basic lighting and device charging sits closer to 200 watts. A full-time RV lifestyle with a residential refrigerator, entertainment system, and working-from-the-road power needs can push you toward 600 watts or beyond.

The number of appliances you’re running makes a huge difference. A 12V compressor fridge draws roughly 40-50 amp-hours per day. Add a CPAP machine, laptop, lights, and a fan, and you’re looking at 100+ amp-hours of daily consumption. Your solar panels need to replace that every day — and your batteries need to store enough to get you through the night. If you’re unsure about your power needs, understanding the differences between 30 amp and 50 amp RV systems can be crucial for efficient energy management.

The 4 Core Components Every RV Solar System Needs

Every RV solar system — regardless of size or brand — is built around the same four components. Getting each one right is what determines whether your system performs flawlessly for a decade or leaves you in the dark on a Tuesday night in the middle of nowhere. For more on maintaining your system, check out our RV maintenance guide.

Solar Panels: The Power Source

Solar panels are the first link in the chain. They capture sunlight and convert it into DC electricity, which then flows through the rest of your system. For RV use, panels are either mounted permanently on the roof or deployed as portable units that can be angled toward the sun for maximum output. Most quality RV panels today are monocrystalline, with efficiency ratings typically ranging from 19% to 23%.

Charge Controllers: MPPT vs. PWM

The charge controller sits between your solar panels and your battery bank, regulating the voltage and current coming in to prevent overcharging. There are two types: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking). MPPT controllers are significantly more efficient — often 20-30% more so than PWM — and are the standard choice for any serious RV solar setup. The Renogy 400 Watt RV Kit, for example, includes a 40 Amp MPPT charge controller specifically because of this efficiency advantage.

Battery Banks: Lithium vs. AGM

Your batteries store the power your panels generate so you can use it after sunset. The two most common options are AGM (Absorbent Glass Mat) and lithium iron phosphate (LiFePO4). Lithium batteries are lighter, charge faster, have a longer lifespan (typically 2,000–5,000 cycles vs. 300–500 for AGM), and can be safely discharged to nearly 100% of their capacity. AGM batteries are cheaper upfront but offer less usable capacity and wear out faster. For full-time or frequent RV use, lithium is the clear long-term winner.

Inverters: Converting DC to AC Power

Your RV’s solar system produces DC power, but most household appliances run on AC. An inverter bridges that gap. For basic use, a 1,000-watt pure sine wave inverter handles most devices cleanly. If you’re running sensitive electronics, a coffee maker, or a microwave, a pure sine wave inverter is non-negotiable — modified sine wave inverters can damage certain appliances and reduce efficiency. For those interested in understanding more about power needs, you might find the comparison between 30 amp vs 50 amp RV systems insightful.

Best RV Solar Kits on the Market Right Now

Choosing the right solar kit comes down to matching your power needs, roof space, and budget. The five options below represent the best the market has to offer right now, each excelling in a specific category that matters to RV owners.

1. Renogy 400 Watt 12 Volt Solar RV Kit: Best Overall

The Renogy 400 Watt 12 Volt Solar RV Kit earns the best overall title for good reason. It includes four 100-watt monocrystalline solar panels rated at 21% efficiency, a 40 Amp MPPT solar charge controller, four Z-brackets for roof mounting, and Renogy’s Bluetooth monitoring module. At $799.99 (check latest price on amazon), it’s one of the most complete and cost-effective entry points into RV solar available today.

The 400 watts of combined output is enough to power small appliances for extended periods during off-grid trips. The included MPPT controller maximizes every watt your panels produce, and the Bluetooth module lets you monitor your system’s performance in real time directly from your phone — a feature that used to be reserved for much more expensive setups. For more insights on smart investments for RV enthusiasts, check out our eTrailer review.

If you’re new to RV solar and want a system that covers all the bases without requiring you to piece together components individually, the Renogy 400W kit is where to start.

2. Rich Solar 400 Watt Solar Kit: Best Runner-Up

The Rich Solar 400 Watt Solar Kit is a strong runner-up that competes closely with Renogy on both performance and price. It includes two 200-watt monocrystalline panels, a 40 Amp MPPT charge controller, four Z-brackets, and all necessary wiring connectors. The two-panel configuration (rather than four) makes roof layout and wiring slightly simpler, which is a genuine advantage for DIY installers working with limited roof space or complex layouts.

3. BougeRV Yuma 200 Watt Flexible Solar Panel: Best Portable Option

Not every RV solar setup needs to be bolted to the roof. The BougeRV Yuma 200 Watt Flexible Solar Panel is built for RV owners who want portability and versatility without sacrificing meaningful power output. Its flexible design means it can conform to curved RV roofs where rigid panels simply won’t fit, or be deployed on the ground and angled toward the sun for peak efficiency. It’s the ideal solution for weekenders who want solar without a permanent installation.

4. Jackery SolarSaga 200W Solar Panel: Highest Efficiency

• Peak efficiency rating that outperforms most panels in its class
• Foldable, portable design built for RV owners who move frequently
• Compatible with Jackery’s Explorer power station lineup for a seamless ecosystem
• IP67 waterproof rating on the junction box for reliable all-weather performance

The Jackery SolarSaga 200W Solar Panel stands out in the portability category while delivering efficiency numbers that rival permanently mounted systems. Its monocrystalline cells push conversion efficiency to the top of the portable panel category, making it an excellent choice for RV owners who want maximum output from a compact, deployable unit.

Where the SolarSaga really earns its place is in how cleanly it integrates with the broader Jackery ecosystem. Pair it with a Jackery Explorer power station and you have a complete, self-contained solar power setup that requires zero permanent installation. For weekend campers, van lifers, or RV owners who aren’t ready to commit to a rooftop system, this combination is genuinely hard to beat.

The one trade-off worth noting is that at 200 watts, a single SolarSaga panel won’t cover high-demand power needs on its own. Most users running this panel pair two units together to hit the 400-watt threshold that makes all-day off-grid living comfortable. Generators are sold separately from the panel itself, and the overall kit cost can rise quickly if you need to build out a full system around it.

5. BLUETTI PV420 Solar Panel: Most Reliable Brand

The BLUETTI PV420 Solar Panel is the choice for RV owners who prioritize long-term reliability above all else. BLUETTI has built a reputation for producing solar equipment that holds up under real-world conditions — consistent output, durable build quality, and dependable performance across thousands of charge cycles. The PV420 delivers 420 watts from a single panel, which makes it one of the highest-output single panels available for RV use today. If roof space is limited and you need to extract the most power from the fewest panels, the BLUETTI PV420 makes a compelling case.

Monocrystalline vs. Polycrystalline vs. Flexible RV Solar Panels

Panel technology has a direct impact on how much power you get, how long your panels last, and whether they’ll even fit your RV’s roof. The three types you’ll encounter most are monocrystalline, polycrystalline, and flexible — and they are not interchangeable. Each has a specific set of strengths that makes it better suited to certain RV setups and travel styles.

Efficiency and Output Differences That Matter Off-Grid

Monocrystalline panels are the gold standard for RV solar. They’re made from a single crystal structure, which gives them efficiency ratings typically between 19% and 23% — the highest available in consumer solar. They perform better in low-light conditions and have a longer lifespan, making them the default recommendation for any permanent rooftop installation.

Polycrystalline panels are made from multiple silicon fragments and are noticeably less efficient, usually in the 15–17% range. They’re cheaper to manufacture, but the lower efficiency means you need more roof space to generate the same amount of power. For RVs with constrained rooftop real estate, this trade-off rarely makes sense. Flexible panels occupy a unique middle ground — they’re lightweight and can conform to curved surfaces, but most sacrifice some efficiency and long-term durability compared to rigid monocrystalline panels.

Which Panel Type Works Best for Your RV Roof

For most RV owners with a flat or low-slope roof, rigid monocrystalline panels are the right answer — full stop. They deliver the most power per square foot, last the longest, and are compatible with standard Z-bracket mounting systems. Flexible panels make the most sense when your roof has a pronounced curve, when weight is a critical concern, or when you want a low-profile installation that sits flush against the roof surface without raised mounting hardware.

How to Size Your RV Solar System Correctly

Sizing your system correctly is the single most important step in the entire process. Undersized systems leave you rationing power. Oversized systems waste money on equipment you’ll never fully use. The four-step process below takes the guesswork out of it entirely.

Step 1: Calculate Your Daily Energy Consumption

Start by listing every appliance you plan to run and how many hours per day you’ll use each one. Multiply the wattage of each device by its daily hours of use to get watt-hours. Add those numbers together and you have your daily energy consumption in watt-hours.

Example Daily Load Calculation:
12V Compressor Fridge (45W × 24hrs × 35% duty cycle) = 378 Wh
Laptop (65W × 4hrs) = 260 Wh
LED Lighting (20W × 5hrs) = 100 Wh
Phone Charging (10W × 2hrs) = 20 Wh
Fan (30W × 8hrs) = 240 Wh
Total Daily Consumption: ~998 Wh

Step 2: Determine How Many Panels You Need

Once you have your daily watt-hour number, divide it by the average peak sun hours at your typical travel locations — usually between 4 and 6 hours per day for most of the continental US. That gives you the minimum solar wattage required to replenish what you consume each day. Using the example above, 998 Wh ÷ 5 peak sun hours = roughly 200 watts of solar panels needed under ideal conditions.

Always build in a buffer of at least 25% to account for panel inefficiency, shading, dust, and non-ideal sun angles. That same example system should realistically be sized at 250–300 watts minimum, and 400 watts if you want comfortable headroom on cloudy days or during heavy usage periods.

Step 3: Choose the Right Battery Capacity

A common rule of thumb is to store enough battery capacity to power your RV for one to two days without any solar input — this covers overcast days and nights without leaving you stranded. For a system consuming 1,000 Wh per day, that means sizing your battery bank at 2,000 Wh (or 2 kWh) minimum. In amp-hours at 12V, that works out to roughly 166 amp-hours of lithium capacity, or closer to 330 amp-hours if you’re using AGM batteries (since you should only discharge AGM to 50% to protect their lifespan).

Lithium iron phosphate batteries are worth the premium for full-time or frequent RV use. Their deeper usable discharge, faster charge acceptance, and dramatically longer cycle life make them the more cost-effective choice over a 5–10 year ownership horizon, even with the higher upfront price tag.

Step 4: Match Your Charge Controller to Your System

Your charge controller needs to handle the maximum current your solar array can produce. To find the right size, divide your total panel wattage by your system voltage (typically 12V or 24V), then add a 25% safety buffer. A 400-watt array on a 12V system produces a maximum of about 33 amps — meaning a 40 Amp MPPT controller (like the one included in the Renogy 400W kit) is the correct size for that configuration.

Always choose MPPT over PWM for any system above 200 watts. The efficiency gains are real and measurable, particularly in the morning and evening hours when panel voltage is lower — exactly the conditions where PWM controllers leave significant power on the table.

RV Solar Panel Installation: Step-by-Step

Installing an RV solar system is a genuinely manageable DIY project if you approach it methodically. The electrical work is straightforward, the mounting hardware is designed for non-professionals, and the payoff — complete energy independence — is immediate. Here’s exactly how to do it right the first time.

Tools and Safety Equipment You Need Before Starting

Before you get on the roof or touch a wire, gather everything you need. Working with electrical systems and elevated surfaces demands proper preparation — shortcuts here create safety risks and installation errors that are frustrating and expensive to fix later. For a comprehensive understanding of maintaining your RV, check out our RV maintenance guide.

• Drill with bits sized for your mounting hardware
• Screwdrivers (flathead and Phillips)
• Wire strippers and crimping tool
• Multimeter for voltage testing
• Self-leveling lap sealant (Dicor is the RV industry standard)
• MC4 connector tool
• Safety glasses and non-slip footwear for roof work
• Cable ties and conduit for wire management

Never work on the roof without appropriate footwear and always be aware of your surroundings — RV roofs can be slippery, especially the rubber EPDM varieties common on travel trailers and Class A motorhomes. If you’re not comfortable working at height, the mounting portion of the job is worth hiring out while you handle the wiring yourself. For more tips on maintaining your RV, check out our complete guide to RV maintenance.

How to Mount Solar Panels on an RV Roof

Start by mapping out your panel placement before drilling a single hole. Lay the panels on the roof and trace around the Z-brackets to find the optimal positions — keeping panels away from roof vents, AC units, and any obstructions that could cast shade during peak sun hours. Even partial shading on a single panel can significantly reduce output across your entire array, so placement precision here directly affects your system’s real-world performance.

Once positions are confirmed, drill pilot holes for each Z-bracket, apply a generous bead of Dicor lap sealant around each hole before setting the bracket, and secure with stainless steel screws. After the brackets are fastened, apply another layer of Dicor over the bracket base and screw heads to create a fully waterproof seal. Skipping or skimping on sealant is one of the most common and costly RV solar installation mistakes — a single water intrusion point can cause thousands of dollars in roof damage over time.

Wiring Your Solar Panels to the Charge Controller

Run your panel wiring through the roof using a dedicated cable entry gland — never drill a bare hole and feed wire through it. The entry gland creates a weatherproof seal and gives your cables a clean, protected path from the roof into the RV’s interior. From there, run your positive and negative leads directly to the solar input terminals on your MPPT charge controller, matching polarity carefully. Use appropriately sized wire for your system — most 400-watt 12V setups require at least 10 AWG wire for panel-to-controller runs, and heavier gauge for longer cable runs to minimize voltage drop.

Connecting Your Battery Bank and Inverter

Connect your charge controller’s battery output terminals to your battery bank using short, heavy-gauge wire — typically 4 AWG or larger depending on your system’s amperage. Keep these cable runs as short as physically possible. Every extra foot of wire between your controller and battery adds resistance and reduces charging efficiency in ways that compound over thousands of charge cycles.

Your inverter connects directly to the battery bank — positive to positive, negative to negative — with an appropriately sized fuse installed as close to the battery terminal as possible. This fuse is your system’s last line of defense against a catastrophic short circuit, and it is non-negotiable. Size the fuse to match your inverter’s maximum input current rating, not your typical load.

• Install a battery disconnect switch between the battery and inverter for safe maintenance access
• Use tinned marine-grade wire for all battery connections to resist corrosion
• Fuse every positive wire within 18 inches of the battery terminal
• Label all wires clearly before closing up panels or cabinets
• Keep battery terminals clean and coated with anti-corrosion spray

Once all connections are made, double-check every terminal for tightness. Loose connections are the leading cause of voltage drop, heat buildup, and system failures in DIY RV solar installations. A quick tug-test on every wire takes two minutes and can prevent a significant headache down the road.

Testing the System Before Hitting the Road

Before you close everything up and celebrate, verify the system is working correctly. Take your multimeter and check the voltage at the battery terminals with the panels connected and sunlight hitting them — you should see your charge controller actively pushing current into the battery bank. Check the controller’s display or app to confirm it’s reading accurate panel input voltage and battery state of charge.

Run your inverter under load for at least 30 minutes before your first trip. Plug in a known appliance, confirm it runs cleanly, and check that the inverter isn’t reporting any fault codes. If your charge controller has a Bluetooth module like the one included in the Renogy 400W kit, connect to it via the companion app and verify all readings match your expectations. A system that tests clean at home is a system you can trust two hundred miles from the nearest electrician.

Common RV Solar Mistakes That Kill Your System Early

Even well-intentioned installations go wrong in predictable ways. The mistakes below aren’t rare edge cases — they’re patterns that show up repeatedly in RV solar systems that underperform or fail prematurely. Knowing them upfront is the easiest way to avoid them entirely.

Undersizing Your Battery Bank

The single most common RV solar mistake is building a generous solar array and pairing it with a battery bank that’s too small to store what the panels produce. Solar panels can only charge what your batteries can hold — if your bank fills up by noon, every watt your panels generate for the rest of the afternoon is wasted. Worse, a small battery bank depleted by overnight use creates situations where you’re running critically low on power before the sun is even high enough to meaningfully charge.

• Size your battery bank for at least 1.5–2 days of consumption without solar input
• Account for the 50% depth-of-discharge limit on AGM batteries when calculating usable capacity
• Factor in temperature — lithium batteries lose capacity in cold conditions, AGM loses it even faster
• Build in room to expand — modular battery systems let you add capacity as your power needs grow

If you’re choosing between spending more on additional solar panels or more on battery capacity, prioritize the batteries first. More panels can’t help you if there’s nowhere to store what they generate. A well-sized battery bank makes your entire system more resilient and gives you meaningful autonomy during stretches of cloudy weather.

Lithium iron phosphate battery banks are the clear upgrade choice here. Their ability to safely discharge to 80–100% of rated capacity — compared to AGM’s 50% limit — effectively doubles your usable storage without adding a single extra battery to the bank. For full-time RV living, the math on lithium pays off within a few years of ownership.

Ignoring Shade Impact on Panel Output

Shade is the silent killer of RV solar systems, and most people dramatically underestimate its impact. In a standard series-wired panel array, shading just 10% of a single panel can reduce the output of your entire array by 50% or more. This isn’t a theoretical worst case — it happens every time a tree branch, roof vent, or AC unit shadow touches one of your panels during peak sun hours.

The solution works on two levels: placement and wiring. During installation, map out where shadows fall on your roof throughout the day and position panels accordingly. Keep panels clear of any rooftop obstruction that casts shade during the 10am–3pm window, which is when the sun is highest and your panels are most productive. Even a few inches of clearance from a vent stack can make a meaningful difference.

On the wiring side, consider adding power optimizers or bypass diodes to your panel string. These devices allow shaded panels to be effectively bypassed so they don’t drag down the performance of unshaded panels. Some MPPT charge controllers also handle shading scenarios more intelligently than others — it’s worth checking the shade mitigation features of any controller you’re considering before purchasing.

The Right RV Solar System Depends on How You Travel

A weekend camper who hits a campground twice a month has completely different solar needs than someone living full-time in a Class A motorhome. Weekend warriors can often get by with a portable 200-watt setup like the BougeRV Yuma or Jackery SolarSaga paired with a modest battery bank. Full-timers need a permanently mounted system of at least 400 watts, a lithium battery bank sized to two days of consumption, and an MPPT controller that can handle future expansion. Match your system to your actual travel pattern — not your aspirational one — and you’ll spend money on equipment that genuinely improves your life on the road rather than hardware that sits underutilized. For those who are unsure about the power requirements, understanding the difference between 30 amp and 50 amp RV systems can be beneficial.

Frequently Asked Questions

RV solar generates a lot of questions — particularly from owners who are used to thinking about power in terms of shore power amps rather than watt-hours and peak sun hours. The questions below cover the scenarios that come up most often, with straight answers that cut through the confusion.

Every situation is a little different depending on your RV type, travel style, and existing electrical setup, but the fundamentals below apply broadly across the vast majority of RV solar installations. For those looking to maintain their RVs in peak condition, it’s also crucial to consider regular RV maintenance.

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

Running an RV air conditioner on solar power is one of the most demanding things you can ask of a solar system. A standard 13,500 BTU rooftop AC unit draws roughly 1,200–1,500 watts at startup and 600–900 watts while running. To power it reliably on solar alone, you’re looking at a minimum of 1,200–1,500 watts of solar panels paired with a substantial lithium battery bank and a high-capacity pure sine wave inverter rated for the startup surge.

Most standard RV solar setups in the 400-watt range are not designed to run air conditioning. If cooling is a priority for your off-grid camping, size your system specifically around that load — or consider a soft-start device like the Micro-Air EasyStart 364, which reduces your AC’s startup amperage by up to 70% and makes solar-powered air conditioning significantly more achievable with a mid-sized system.

Can I Install RV Solar Panels Myself or Do I Need a Professional?

Yes, you can absolutely install RV solar panels yourself — and thousands of RV owners do it successfully every year. The mounting work requires basic comfort with a drill and roof sealant. The wiring is low-voltage DC, which is far more forgiving than household AC wiring. Most quality solar kits, including the Renogy 400W RV Kit, are specifically designed for DIY installation and come with detailed instructions that walk you through every step.

That said, there are situations where professional help makes sense. If your RV has a complex roof layout, an existing electrical system you’re integrating with, or if you’re installing a large system above 800 watts, having an experienced RV solar installer review your plans — or handle specific portions of the job — is money well spent. The cost of fixing an improperly installed system almost always exceeds the cost of getting it right the first time.

How Long Do RV Solar Panels Last?

Quality monocrystalline solar panels are built to last. Most manufacturers rate their panels for 25 years of useful life, with a typical performance warranty guaranteeing at least 80% of original output at the 25-year mark. In practice, well-maintained RV solar panels regularly exceed this, continuing to produce meaningful power well into their third decade. For those interested in other RV enhancements, consider checking out this eTrailer review to see why it’s a smart investment for RV enthusiasts.

The components most likely to need replacement before your panels are the charge controller and inverter, which typically have service lives of 10–15 years under normal use. Batteries are the most frequent replacement item — AGM batteries last 3–5 years under regular use, while lithium iron phosphate batteries are rated for 2,000–5,000 charge cycles, translating to roughly 10–15 years for most RV applications.

• Keep panels clean — dust and debris accumulation reduces output by 5–25% depending on conditions
• Inspect mounting hardware and roof sealant annually for signs of wear or water intrusion
• Check all wire connections at the start of each season for corrosion or loosening
• Monitor your charge controller’s performance data to catch degradation early

What Is the Average Cost of a Full RV Solar System?

A complete entry-level RV solar system — 400 watts of panels, MPPT charge controller, 100Ah lithium battery, and a 1,000-watt inverter — will run between $1,200 and $2,000 for quality components. Mid-tier systems with 600–800 watts of panels and 200Ah of lithium storage typically land in the $2,500–$4,500 range. Full-time RV systems with 1,000+ watts and 400Ah or more of lithium capacity can exceed $6,000–$8,000 before installation costs. The investment pays back through eliminated campground fees, reduced generator fuel costs, and the intangible value of camping anywhere you choose without power anxiety.

Can RV Solar Panels Charge Batteries While Driving?

Yes — and this is one of the underappreciated advantages of a rooftop solar installation. While your RV is in motion, your panels continue generating power from sunlight hitting the roof, and your charge controller continues pushing that energy into your battery bank. On a sunny travel day, you can arrive at your destination with a battery bank that’s already partially or fully charged before you’ve even set up camp. If you’re planning a trip, consider exploring Canyonlands National Park for an unforgettable RV experience.

Most modern RVs also have a built-in connection between the tow vehicle’s alternator and the RV’s house battery bank, which charges the batteries while driving through a separate circuit called a battery-to-battery charger or DC-DC charger. Combining solar input with alternator charging during driving days means your batteries are getting charged from two sources simultaneously — a setup that makes it genuinely difficult to arrive anywhere with a depleted battery bank. For those planning a trip, consider checking out this Arches National Park RV camping guide to ensure you’re well-prepared for your adventure.

For motorhome owners, the same principle applies through the vehicle’s own alternator. As long as the engine is running and the solar panels are producing, your system is in active charging mode. This makes long driving days between destinations a net positive for your energy situation rather than a drain on it.

The bottom line: solar panels don’t care whether your RV is parked or rolling. As long as sunlight is hitting the panels, your batteries are charging — and that continuous, passive energy accumulation is one of the most compelling reasons to invest in a rooftop solar system over portable panels alone.

If you’re ready to take the next step toward energy independence on the road, SolarReviews offers in-depth comparisons, expert guidance, and up-to-date product reviews to help you choose and size the perfect RV solar system for your specific needs.

Whether you’re on the road or setting up camp somewhere, you’ve probably got a need for electricity. With RV’s, there are all kinds of options for how to power up, from the typical generator to personal wind turbines. One power source that has been gaining popularity is solar power from RV solar panels.

Does solar have a place in your rig?

The answer is maybe. There are some definite benefits to using solar power. When it’s sunny out, you can charge your batteries for free. Your only expense is the initial cost of the equipment. Plus solar power is environmentally friendly and doesn’t produce toxic bad smelling fumes as a generator can. However, solar energy may not be an efficient power source for your RV– an average-sized solar panel can only charge up to 25 amps an hour.

Solar energy is a great option as a back-up power source. It can also be useful if you’re going to be camping in one area for a while, as you can set the panels up and let them charge all day long.

What Does A Solar Panel Do?

A solar panel essentially acts as the charging station for your electrical needs. The panel takes light from the sun and converts it to usable energy. This energy can then be stored in a battery used to power your electronics.

What Equipment Do I Need?

You need a solar panel to absorb light. Next, that energy needs to go to an inverter, which is a machine that converts the energy produced by the solar panel into usable energy. Once that energy has been converted, it can be stored in a battery. It is good practice to have multiple batteries available so you can swap them out when one becomes fully charged.

A generator can also be a part of your rig. The generator is useful for days when there isn’t much sunlight and your batteries are drained. Some people don’t find it necessary, however– it really just depends on how heavy your needs for electricity are.

How Much Solar Power Does My RV Need?

This is an important thing to consider prior to purchasing any equipment. Too weak of a panel and you won’t be able to provide enough power to your electronics– you may find yourself without A/C on a hot day. Too powerful of a panel and you won’t be able to store all the excess electricity that your rig produces. It’s best to accurately gauge your electricity needs before committing to a certain sized solar panel.

You will need to have some idea of your energy usage in order to determine the right sized panel for your needs. One way to do this is to see how long it takes you to drain your current battery. Divide that by the number of days. For example, if you used 200 amp-hours over four days, you would need 50 amp hours per day. The average 100-watt solar panel can deliver 30 amp-hours per day, so you would need two 100-watt solar panels.

Wrap Up

Solar energy can be an efficient and a great green option for powering your electronics, and it works well as a back-up or alternate power source. If solar energy is right for you, be sure to first consider what your energy needs are before making a purchase.  For a review check out this link: https://rvsolaracunit.com.
