The best RV panel arrangement fits the usable roof and produces a compatible array without compromising ventilation, access or mounting.
Solar panels are the best passive income your van or RV can have — free power on every sunny day, no noise, no fumes, no moving parts. Choosing the right ones comes down to panel type, wattage, and how they'll mount on your specific roof.
For how solar fits into the full system, see the solar setup guide. For sizing how much solar you need, see how much solar do I need for an RV?.

Rigid vs flexible solar panels
This is the first decision for most builds.
| Rigid | Flexible | |
|---|---|---|
| Efficiency | Higher (20–23%) | Lower (18–21%) |
| Cost per watt | Lower (~$0.60–$1.00/W) | Higher (~$1.00–$2.00/W) |
| Lifespan | 25+ years typical | 5–10 years typical |
| Airflow underneath | Yes — runs cooler | No — gets hot, loses output |
| Roof curve tolerance | Needs flat or near-flat | Can flex slightly |
| Weight | Heavier (8–10 lbs per 100W) | Lighter (4–6 lbs per 100W) |
The verdict: Unless your roof curves significantly (Class B RV, certain Sprinter profiles), use rigid panels. The efficiency advantage, lower cost, and longer lifespan are hard to argue with. Flexible panels make sense for curved roofs, low-profile stealth builds, or builds where every pound matters.
See the full comparison: rigid vs flexible solar panels for an RV.
Monocrystalline vs polycrystalline
Virtually all new panels sold for van and RV use are monocrystalline — higher efficiency, better performance in low light, and black cells that look cleaner. Skip polycrystalline for a new build.
Best rigid solar panels for vans and RVs
Renogy 175W Monocrystalline — Best value rigid
Price: ~$100–$130 | Wattage: 175W | Efficiency: ~20%
Renogy's 175W panel is the most-bought panel in the van life community — for good reason. It's widely available (Amazon, their direct site, and many RV stores), competitively priced, and has a solid 25-year power output warranty. The 175W footprint fits most van roofs without going to a larger (and more wind-prone) 200W panel.
Stack two for a 350W system, three for 525W. These work well with any MPPT charge controller including Renogy's own Wanderer and Rover series.
Rich Solar 200W Monocrystalline — Best bang-per-watt
Price: ~$120–$150 | Wattage: 200W | Efficiency: ~21%
Rich Solar has built a strong reputation in the van life and off-grid community. Their 200W panel offers slightly higher efficiency than Renogy's equivalent and often comes in at a lower price per watt. Less brand recognition but consistently good reviews and a straightforward 5-year material warranty + 25-year power output warranty.
Best for: Builds looking to maximize watts per square foot at the best price.
Newpowa 200W Monocrystalline
Price: ~$110–$140 | Wattage: 200W | Efficiency: ~20.5%
Newpowa is a solid alternative to Renogy and Rich Solar, often slightly cheaper and with a good track record in the van build community. Good availability on Amazon. The IP67-rated junction box is a nice touch.
BougeRV 200W Monocrystalline
Price: ~$100–$130 | Wattage: 200W | Efficiency: ~21%
BougeRV has come on strong in the last two years with aggressive pricing and quality that holds up. Their panels use Grade A cells with a black aluminum frame. A good choice if you're cost-sensitive and willing to go with a newer brand.
Victron Energy BlueSolar 175W
Price: ~$250–$300 | Wattage: 175W | Efficiency: ~21%
Victron panels are significantly more expensive but integrate directly with Victron SmartSolar MPPT controllers — showing panel voltage, current, and peak data in the VictronConnect app. If you're building a Victron ecosystem, the data integration is a genuine advantage. Otherwise, a Renogy or Rich Solar panel feeding a Victron MPPT controller works just as well electrically.
Best flexible solar panels
Renogy 100W Flexible
Price: ~$100 | Wattage: 100W
The safest flexible panel choice if you genuinely need flex. Renogy's warranty support is better than most flexible panel brands, and they're widely available. Note that flexible panels run hotter and degrade faster — factor that into your long-term cost calculation.
BougeRV 200W Flexible (curved)
Price: ~$160–$200 | Wattage: 200W
One of the few flexible panels worth considering at 200W. Designed for up to 30° arc, making it a good fit for Sprinter roofs with a significant crown.
Mounting
Rigid panels are typically rail-mounted or Z-bracket mounted. For most flat van roofs, Z-brackets are the cleanest and lowest-cost option. VHB tape mounting (common on flexible panels) works but doesn't allow airflow and traps heat.
See the mounting guide: how to mount solar panels on a van roof.
What charge controller do you need?
All panels on this list require an MPPT charge controller — a PWM controller wastes 20–30% of the solar input. For most builds, a Victron SmartSolar MPPT 100/30 ($110) or 100/50 ($160) is the right call. See best MPPT charge controllers for RVs.
Wiring panels
For two or more panels, decide between series and parallel wiring first — they affect your MPPT controller selection. See solar series vs parallel wiring for an RV.
Worked planning check
Draw a roof plan including an open vent lid, antenna shadow, rack and walking clearance. Compare total installed watts of layouts that actually fit, rather than choosing the highest-watt individual panel. Retain room to inspect fixings and weather seals after installation.
The figures or dimensions in this example are explicit planning assumptions, not a product test or an installation specification. Replace them with your equipment data and actual measurements.
Planning questions
Should campervan solar panels be in series or parallel?
Compare the resulting voltage and current with the controller limits and evaluate the actual shading pattern. Series adds voltage; parallel adds current. Neither is universally best.
Why does a solar panel produce less than its rated watts?
Nameplate power uses specified test conditions. Sun angle, temperature, shade, dirt and charging-system limits change actual output. Size from seasonal daily energy, not maximum watts alone.
Can I add another panel later?
Recalculate cold open-circuit voltage, short-circuit current, controller output, mounting, cable and protection first. Matching wattage does not prove panels are electrically compatible.
