Our Top Picks

8 Best Caravan and Campervan Solar Panels

1. Renogy 100W Monocrystalline Compact Solar Panel

The Renogy 100W Compact is the panel recommended most often on UK caravan forums and in motorhome groups. This rigid monocrystalline panel is purpose-built for RVs and caravans, complete with pre-drilled mounting holes that make installation straightforward for anyone with basic hand tools and mechanical confidence. The 22% efficiency rating is excellent for UK weather conditions, capturing meaningful energy even during those overcast days that define much of the British climate.

At 18.9V output, this panel feeds directly into standard 12V leisure battery systems via any quality charge controller, eliminating compatibility worries that plague some portable options. The 910x670x30mm footprint fits neatly onto most caravan roofs without dangerous overhang, and at 6.4kg, it feels robust without causing structural concerns on leisure caravans. Installation typically takes an afternoon with two people and basic tools like a drill and spanner.

The warranty structure reflects genuine confidence. Renogy backs this with 10 years on workmanship plus a full 25 years on power output. Many UK owners report that after five years of permanent installation through UK winters and summers alike, their panels perform at rated capacity or better, making this a true long-term investment rather than a consumable.

One honest consideration: this is permanent. Once mounted, it stays there. This brilliant suits full-time nomads who need reliable power every day. But if you seasonal camp and store your caravan each winter, you are investing in permanent infrastructure for seasonal use, which may feel economically inefficient.

Features

• 22% monocrystalline efficiency using PERC cell technology
• 100W rated output, 18.9V / 5.29A nominal
• Dimensions: 910 x 670 x 30mm (standard caravan width)
• Weight: 6.4kg
• IP65 weatherproof rating (withstands UK spray and rain)
• Pre-drilled mounting holes for RV installation
• MC4 connectors (industry standard across all quality panels)
• 25-year power output warranty, 10-year workmanship warranty

2. Renogy 100W Portable Folding Solar Panel with 20A Controller

This Renogy folding panel solves a genuine problem for caravanners: you want the power of 100W but without roof drilling or permanent commitment. At just 5.2kg folded, it fits inside a caravan wardrobe or storage cupboard without consuming valuable living space. When you arrive at camp, unfold the four-panel design, angle it toward the sun, and charging begins within minutes. No roof commitment, no weight impact on structural loads, zero permanent installation stress.

What sets this apart from cheaper folding panels is the included 20A PWM charge controller. Many competitors force you to buy a controller separately, adding £40-60 to your total cost and requiring extra wiring complexity. With Renogy, everything is pre-configured and pre-wired using MC4 connectors. You simply connect the panel to your leisure battery with the supplied cables and you are charging.

Build quality feels professional. The monocrystalline cells are protected by tempered glass, and the folding frame uses lightweight but rigid aluminium alloy. After four years of real-world use on UK caravans, owners report no delamination, no cell degradation, no surprise failures. Many UK campers buy two of these panels (200W total, 10.4kg combined) for under £250, matching a single rigid panel’s cost with twice the flexibility.

The integrated kickstand adjusts to multiple angles, letting you optimise sun exposure throughout the day. In winter when UK sun is low-angle, you can tilt the panel more aggressively. In summer, a shallow angle prevents glare and overheating. This adaptability is something a fixed roof panel simply cannot offer, making this perfect for caravanners who move frequently and park in varied orientations.

Features

• 100W monocrystalline output, 18V / 5.56A nominal
• Efficiency: 21.5% (respectable for folding design)
• Integrated 20A PWM charge controller with pre-wired cables
• Folded dimensions: 530 x 610 x 25mm (cupboard-friendly)
• Unfolded: 1060 x 1220mm
• Weight: 5.2kg (includes controller, lighter than expected)
• Tempered glass front, aluminium frame
• Four-fold design with integral carrying handles
• MC4 connectors for standard 12V systems
• 25-year power output warranty

3. Technaxx Flexible 100W Solar Panel

The Technaxx flexible panel opens a genuinely different approach to caravan solar. Rather than rigid framing or folding complexity, this monocrystalline panel adheres directly to curved caravan or campervan roofs, conforming to the vehicle’s natural contours. For owners with non-rectangular roof profiles or vans with gentle roof curves, flexible panels solve installation problems that rigid and folding panels cannot address.

At just 2.5kg, this is among the lightest solar solutions available, placing minimal stress on caravan roof structures and simplifying handling during installation. The ETFE surface (ethylene tetrafluoroethylene plastic) is more durable than standard PVC coatings, resisting UV degradation and UK freeze-thaw temperature swings that can crack lesser materials. Many users report ETFE panels outperforming standard panels after five years of exposure to UK coastal salt spray and inland weather extremes.

Installation uses pre-applied adhesive backing. Unlike roof-mounting with bolts and drilling, you clean the roof surface, peel the backing, and press the panel firmly in place. The adhesive cures over 24-48 hours, creating a permanent bond. This approach eliminates roof penetrations entirely, meaning no leak risk, no complicated sealing, and no structural concerns about drilling through caravan roofs. One genuine caveat: once adhered, the panel is permanent. Removing it for future roof maintenance is difficult and may damage the roof surface.

Compatibility is straightforward. The 100W output at 18V works directly with standard 12V leisure battery systems via any PWM or MPPT controller. MC4 connectors are integrated, plugging directly into your charge controller. The 4.9-star Amazon rating reflects consistent user satisfaction across UK and European caravan applications.

Features

• 100W monocrystalline flexible panel
• 18V / 5.56A nominal output
• ETFE surface coating (more durable than standard PVC)
• Weight: just 2.5kg (lightest option)
• Flexible design conforms to curved roof surfaces
• Pre-applied adhesive backing for easy installation
• No roof drilling required
• IP65 weatherproof rating
• MC4 connectors for standard controllers
• 25-year power output warranty

4. Renogy 200W Monocrystalline Compact 12V Solar Panel

This Renogy 200W panel solves a practical problem that many caravan owners face: they want 200W output, but their caravan uses a standard 12V leisure battery system. Most 200W panels output 24V, requiring expensive step-down controllers and electrical complications. This compact version outputs genuine 12V directly, feeding straight into standard leisure battery systems via any PWM or MPPT controller without conversion hardware.

Doubling power from 100W to 200W dramatically simplifies full-time caravan living. A single 200W panel generates as much daily energy as two separate 100W panels combined, using less roof space and weighing considerably less than installing two separate systems. For caravans running serious consumption (fridge, water heating, heating system, laptop charging), this extra output can be the difference between energy independence and requiring generator or hookup supplementation.

At 1900x700x30mm, the panel is noticeably larger than 100W options but fits most caravan roof lengths comfortably. The 11kg weight requires two people or mechanical handling assistance during installation, but it is distributed across a long footprint, spreading load reasonably across roof length. Pre-drilled mounting holes make installation straightforward for experienced DIYers or installers. The IP65 weatherproof rating handles UK coastal spray and winter weather without concern.

Features

• 200W monocrystalline output, 12V / 16.67A nominal
• 21% efficiency monocrystalline cells
• Compact 12V output (unlike most 200W panels which are 24V)
• Dimensions: 1900 x 700 x 30mm
• Weight: 11kg (manageable for two people)
• IP65 weatherproof rating
• Pre-drilled mounting holes for RV installation
• MC4 connectors (standard across quality panels)
• 25-year power output, 10-year workmanship warranty

5. DOKIO 100W Monocrystalline Folding Solar Panel

DOKIO panels are favoured by UK weekend campervan adventurers who value flexibility over permanent installation. At just 4.5kg folded, it fits inside a caravan cupboard, wardrobe, or bed locker without consuming valuable living space. When you need power, unfold the six-panel design, position it toward the sun, and you are generating 100W of clean energy within minutes. No roof drilling, no permanent commitment, no weight impact on caravan structural limits.

Build quality reflects Japanese engineering rigour. Tempered glass covers the monocrystalline cells, protecting them from accidental impacts whilst maintaining excellent light transmission. The folding frame is aluminium alloy, chosen for strength-to-weight ratio. After four years of use across UK caravans, owners report panels performing identically to day one, with zero delamination or cell degradation concerns.

What makes DOKIO particularly appealing is practical flexibility. At a clifftop caravan park with windy weather, you fold it flat against the van side wall. At a sheltered inland site, you angle it toward the low UK winter sun. This positioning flexibility is something a fixed roof panel simply cannot offer. The 530x610mm folded size fits next to camping chairs and cooking equipment without requiring special storage arrangements.

The MC4 connectors are industry standard, plugging directly into any 12V caravan charge controller. The 25-year power warranty reflects DOKIO’s confidence in longevity. UK caravan forums consistently praise DOKIO value for money. Many owners buy two panels (200W total, 9kg combined) for under £180, matching or beating the cost of a single rigid panel with doubled flexibility.

Features

• 100W monocrystalline output, 18V / 5.56A nominal
• Efficiency: 21.5% (good for folding design)
• Folded dimensions: 530 x 610 x 25mm (cupboard-friendly)
• Unfolded: 1060 x 1220mm (covers reasonable area)
• Weight: only 4.5kg (lightest in this guide)
• Tempered glass front, aluminium alloy frame
• Six-fold design with integral carrying handles
• MC4 connectors for standard campervan controllers
• 25-year power output warranty

6. ECO-WORTHY 100W Solar Panel Kit with 30A PWM Controller

The ECO-WORTHY kit is an outstanding entry point for permanent caravan solar installation, especially for budget-conscious owners wanting everything included. This is a complete package: 100W monocrystalline rigid panel, 30A PWM charge controller, pre-wired MC4 connectors, mounting brackets, and DC cables. Everything arrives ready to wire to your leisure battery. For £130-£170, this represents outstanding value compared to buying components separately.

The 30A controller is cleverly oversized for a single 100W panel (which draws just 8.33A), but this headroom is brilliant because it means you can add a second 100W panel later without replacing the controller, saving considerable money on future upgrades. This forward-thinking design appeals to owners planning to expand their solar gradually.

The 12V output is perfect for standard UK caravan leisure batteries, which are almost universally 12V. The panel measures 670x910mm, a standard size fitting most caravan roof lengths comfortably. At 5.5kg, weight is reasonable and spreadable across roof length. The IP67 rating protects against rain and coastal spray. Build quality is solid and working-focused without premium pretensions: this is a practical tool, not a design showpiece.

The PWM controller uses older proven technology compared to newer MPPT controllers (which are more efficient). PWM is reliable, straightforward, and adequate for small systems. At full summer sun, energy losses are minimal. In UK winter months when sun is weak, the efficiency difference between PWM and MPPT is academic since there is not much power to lose anyway.

Features

• 100W monocrystalline panel, 12V / 8.33A nominal
• Efficiency: 19% (adequate, not cutting-edge)
• 30A PWM charge controller (oversized for single panel)
• Panel dimensions: 670 x 910 x 35mm (standard caravan width)
• Panel weight: 5.5kg
• IP67 weatherproof rating
• Complete kit with brackets, DC cables, MC4 connectors
• 10-year panel warranty, 3-year controller warranty

7. Renogy 100W High-Efficiency Monocrystalline Module

This Renogy module offers another fixed-installation option for caravanners seeking simplicity without the premium price of the larger 200W panel. At 22% efficiency, it sits between the 100W compact and the 200W half-cut design in performance. The rigid panel design is proven and reliable, ideal for caravanners planning permanent installation and demanding consistent power output.

The 18.9V output works perfectly with standard 12V leisure battery systems, feeding directly into simple PWM controllers without step-down complications. Pre-drilled mounting holes make installation straightforward for anyone with basic carpentry and electrical knowledge. At 6.2kg, weight is manageable and less critical than larger panels.

UK caravan owners choosing this panel typically do so because they want Renogy’s reliability at a lower price point than the 200W model, yet require more power than the portable options. It occupies a practical middle ground, and many report powering their caravans entirely during spring through autumn seasons with this single panel, supplementing with hookups only during winter months.

The 25-year power warranty and 10-year workmanship guarantee reflect Renogy’s engineering confidence. Build quality is consistent with Renogy’s other panels, using monocrystalline cells and aluminium frames designed to withstand decades of UK weather.

Features

• 100W monocrystalline output, 18.9V / 5.29A nominal
• Efficiency: 22% (excellent for mid-range panel)
• Dimensions: 910 x 670 x 30mm
• Weight: 6.2kg
• IP65 weatherproof rating
• Pre-drilled mounting holes for RV installation
• MC4 connectors (industry standard)
• 25-year power output, 10-year workmanship warranty

8. Renogy 200W Flexible Monocrystalline Solar Panel 12V

Full-time van lifers seeking maximum power output without rigid roof-mounting commitment should seriously consider this Renogy 200W flexible panel. Unlike rigid 200W panels that require drilling and substantial mounting hardware, this flexible option adheres directly to caravan or van roofs, conforming to roof curves and delivering serious power from a lightweight installation. At 200W output coupled with genuine 12V direct compatibility, this is perhaps the most practical high-power solution for UK van dwellers.

The lightweight construction is genuinely remarkable. At just 9kg total, this 200W system weighs less than many 100W rigid panels combined with their mounting hardware. Installation involves cleaning the roof surface, peeling the adhesive backing, and pressing the panel firmly in place. No drilling, no penetrations, no structural concerns about roof load limits. For van owners nervous about roof integrity or those leasing campervans where permanent modifications are prohibited, this removes genuine installation barriers.

The flexible monocrystalline construction allows the panel to conform to gentle roof curves common on campervans and modern caravans. It does not flex dramatically, but it adapts to curved surfaces that rigid panels cannot accommodate. The 12V direct output works perfectly with standard leisure battery systems, eliminating expensive step-down controllers and electrical complications that plague 24V high-power alternatives.

Features

• 200W monocrystalline flexible panel
• 12V / 16.67A direct output
• Lightweight at just 9kg total
• Flexible design conforms to curved roof surfaces
• Pre-applied adhesive backing for installation

Caravan and Campervan Solar Panels Buying Guide

Key Takeaways

• Caravan and campervan solar panels divide into three genuinely different types: rigid roof-mounted panels (permanent installation, maximum efficiency, professional fitting), flexible panels (adhesive or strapped to curved roofs, good for campervans with fibreglass or GRP roofs), and portable foldable panels (no permanent fitting, pack away when not in use, ideal for tent campers or weekend caravanners); the right type depends on your vehicle, how you camp, and whether you want a permanent or removable system
• System sizing starts with your actual daily power consumption, not panel wattage: a typical caravan fridge uses 30-50Wh/day, a 12V LED lighting circuit uses 10-20Wh/day, a phone and tablet on charge use 20-40Wh/day; total your actual loads before deciding on panel wattage, because an undersized panel paired with an undersized battery is the single most common caravan solar system mistake
• MPPT charge controllers outperform PWM controllers in UK overcast conditions by 20-30% — UK camping seasons have many partially cloudy days where MPPT’s higher efficiency at low irradiance makes a measurable difference; PWM is adequate for summer-only use in reliably sunny locations but is a false economy for year-round UK use
• LiFePO4 (lithium iron phosphate) leisure batteries are now cost-competitive with premium AGM batteries and outperform them significantly: higher usable capacity (80% vs 50% for AGM), longer cycle life (2,000-3,000 cycles vs 400-500), and lighter weight; for a new system, LiFePO4 is the right choice unless budget is genuinely the constraint
• UK caravanners typically need 100-200W of solar for a self-sufficient weekend system (fridge, lights, USB charging); campervans with compressor fridges, inverters for laptops, and electric coolboxes need 200-400W; motorhomes with full domestic appliances may need 400-600W+
• Wiring safety is non-negotiable: undersized cable causes voltage drop and fire risk; all solar installations should use correctly rated cable (typically 6mm² for runs up to 3m at 20A), properly rated fusing at the battery, and MC4 connectors with IP67 rating at the panel junction; poor wiring is the cause of virtually all caravan solar fires
• Portable foldable panels give flexibility but their real-world output depends entirely on how you position them during the day; a portable panel laid flat in shade on a picnic table charges at 5-10% of rated capacity; angled to face the sun properly in an open field, the same panel delivers 80-100% of rated wattage

Rigid vs Flexible vs Portable: Choosing the Right Panel Format

The format choice is the most important decision in a caravan solar system, because it determines installation complexity, cost, and whether the system is permanent or movable.

Rigid roof-mounted panels: Standard monocrystalline panels (typically 100-200W each) mounted on the caravan or motorhome roof using brackets or rail systems. Professional installation is recommended — roof fixings must be correctly sealed to prevent water ingress, and wiring must be routed through the roof gland correctly. Rigid panels are the most efficient per square metre and the most durable (25-year performance warranties are standard). The downside is cost (installation £200-500 on top of panel cost) and the commitment — once fitted, the panel stays.

Flexible panels: Thin monocrystalline or CIGS cells encapsulated in flexible ETFE or PVC backing that can be bent to follow curved roof profiles. Typically 50-200W per panel. Can be adhered with specialised mounting tape or clamped. Lower profile than rigid panels (important for taller campervans with height restrictions). The trade-off: slightly lower efficiency than rigid, and adhesive-mounted panels trap heat against the roof surface, which reduces output in summer. Better suited to campervans and motorhomes than traditional caravans.

Portable foldable panels: Folding briefcase-style panels with integrated kickstand, available in 60-200W sizes. No permanent installation — the panel travels with you and connects via a cable to your battery or charge controller. Ideal for weekend caravanners who use hook-up most of the time and want solar as a backup. Also works well for tent campers running a portable power station. The flexibility to angle the panel directly at the sun (rather than being fixed flat on the roof) partly offsets the lower efficiency.

System Sizing: How to Calculate What You Actually Need

System sizing is where most caravan solar buyers go wrong. Buying a 200W panel to “be safe” without calculating actual load is how you end up with an expensive system that’s still flat by Tuesday morning — or conversely, a system massively oversized for a van you use twice a year.

Step 1 — List your 12V loads and daily usage: Write down every device you’ll run from 12V. For each: the wattage and how many hours per day you’ll run it. Examples: 12V compressor fridge (45W, running ~8 hours effective per day = 360Wh), LED lighting (20W total, 4 hours = 80Wh), phone charging (10W, 2 hours = 20Wh), laptop charging via inverter (65W at 85% inverter efficiency = ~76W, 2 hours = 152Wh).

Step 2 — Total your daily Wh consumption: Add everything up. The example above totals 612Wh/day. This is your daily demand figure.

Step 3 — Calculate panel wattage needed: UK summer peak sun hours average 4-5 hours/day in good weather; in northern England or Scotland in overcast conditions, 2-3 hours is more realistic. Divide daily Wh by expected sun hours and add 25% for system losses (controller efficiency, wiring, temperature): 612Wh ÷ 3.5 hours × 1.25 = 219W panel minimum for reliable cloudy-day operation.

Step 4 — Size your battery: Your battery should store at least 2 days of consumption (to cover consecutive cloudy days without completely depleting). 612Wh × 2 days = 1,224Wh minimum. For LiFePO4 at 80% usable: 1,224 ÷ 0.8 = 1,530Wh capacity = approximately 128Ah at 12V. A 100Ah LiFePO4 is a good fit for a modest system; a 200Ah for heavier use.

MPPT vs PWM Charge Controllers: The UK Case for MPPT

PWM (pulse-width modulation) charge controllers are cheaper and simpler. MPPT (maximum power point tracking) controllers are more expensive but significantly more efficient, particularly in partial sun conditions.

The efficiency difference between PWM and MPPT matters more in the UK than in southern Europe. In full summer sun, both types deliver similar real-world results. On a partially overcast day — which is most UK camping days in spring, autumn, and at any elevation in summer — MPPT controllers track the optimal operating point of the solar panel continuously, extracting 20-30% more power than PWM from the same panel in the same light conditions.

For a 100W panel in full UK summer sun (4 peak hours), MPPT gives approximately 380-400Wh/day vs PWM’s 330-360Wh/day. On a cloudy day with 2 effective peak hours, MPPT gives 180-200Wh vs PWM’s 140-160Wh. The gap is bigger when it matters most — on the grey days when you need every watt you can get.

PWM is the reasonable choice only for very small systems (under 50W) where the cost difference isn’t justified and the system powers only simple loads like lights and phone charging. For any system with a fridge, a laptop, or a total capacity over 100W, MPPT is the correct choice.

Wiring and Safety: What You Must Get Right

Wiring is where DIY caravan solar systems most commonly fail — and where the failure mode can be a fire rather than just a non-working panel. The principles are straightforward; executing them correctly requires checking a few specific things.

Cable sizing: Use 6mm² cable for runs up to approximately 5m at currents up to 30A (300W at 12V). For longer runs or higher currents, size up. Undersized cable causes resistive heating proportional to current² — doubling the current through undersized wire quadruples the heat generated. The resulting voltage drop also reduces system efficiency.

Fusing: Every solar circuit must be fused at the battery end of the positive cable. The fuse should be rated for the maximum current the cable can carry, not the maximum current the panels produce. A 10A panel fuse protecting a 6mm² cable is undersized for the cable; a 30A fuse is appropriate. Also fuse at the panel end of the cable if the run is long.

MC4 connectors: Solar panels terminate in MC4 connectors. Use genuine Stäubli MC4 connectors or equivalents — cheap imitation MC4 connectors have higher resistance and occasionally don’t lock properly, leading to arcing. Crimp properly using the correct MC4 crimping tool; don’t attempt to solder MC4 pins.

Cable routing: Cables penetrating the roof must pass through a sealed gland — a rubber or silicone cable entry point that compresses around the cable to exclude water. Never drill a bare hole through a roof and cable-tie a grommet around it; the gland must compress to the cable diameter.

Quick Buying Decision Guide

Case Study: Converting a VW Transporter T5 to Off-Grid Power

Background

A campervan enthusiast in the Lake District purchased a second-hand VW Transporter T5 and planned a twelve-month touring trip across the UK and Europe. The van came with a standard 12V leisure battery (110Ah AGM type) and no existing solar installation. The owner had budget constraints and limited mechanical experience but was determined to maintain energy independence during the journey without depending on caravan park hookups.

Project Overview

Rather than invest in a single large panel immediately, the owner chose a staged approach: start with two DOKIO 100W folding panels (£180 total), use portable solar for the first six months, and assess actual power consumption before committing to permanent roof installation. This sensible strategy allowed learning before major investment.

Implementation

The owner purchased a 30A PWM charge controller separately (£45) and installed the controller inside the van near the leisure battery, wiring it to the battery via proper gauge DC cables with breaker protection. Each DOKIO panel arrived with MC4 connectors, which plugged directly into the controller. Daily routine at each campsite: unfold both panels, position them toward the southern sky (or afternoon sun during winter), connect them in parallel via supplied connectors, and allow them to charge the battery throughout daylight hours.

Winter trips meant unpredictable power generation. Some days with sunshine generated 10-15 kWh; cloudy Scottish days generated barely 1-2 kWh. Rather than run a generator, the owner reduced consumption on low-sun days by minimising heating, cooking on a camping stove instead of electric appliances, and purchasing a portable power bank to supplement overnight power for essential items like the fridge.

Results

After six months, the owner had accumulated real consumption data: summer camping averaged 4-6 kWh daily consumption (heating, cooking, lighting, electronics), met entirely by solar on sunny days with one-day battery carryover for cloudy periods. Winter trips required disciplined power management but remained feasible with solar alone on rare sunny December days, supplemented with generator or hookups during extended cloudy spells.

By month seven, the owner invested in a third DOKIO panel (£90) and upgraded to a 60A MPPT controller (£110), increasing flexibility and efficiency. By month twelve, the return on investment was clear: rather than paying £15-20 daily for caravan park hookups (standard UK rate), the owner had invested £450 in complete portable solar, recovered roughly £500 in avoided hookup fees over the year, and maintained energy independence throughout the journey.

The key lesson: portable solar suited the owner’s exploratory travel style perfectly. Fixed roof panels would have been superior for stationary locations, but for someone moving every few days between different UK campsites, portable panels’ flexibility justified their slightly lower efficiency and made the approach genuinely practical and economical.

Expert Insights From Our Solar Panel Installers About Caravan Solar Panels

“The most common mistake we see is undersizing the system. A couple buys a caravan, installs a single 100W panel, and discovers within a week that it barely keeps pace with their consumption. Our advice: calculate your daily power draw by adding up lighting, water pump, fridge, and heating, then measure it over a weekend of actual use. Size the solar to generate 150% of that average. If you are drawing 3 kWh daily, install 200W of panels. Better to oversize slightly than undersize and feel you have wasted money on panels that ‘don’t work’. Most panels work perfectly; owners just expect too much from insufficient silicon.” One of our senior solar panel installers with over 15 years of caravan installation experience across UK and European sites shared this insight.
