So you want to go solar. Good choice. But here's what nobody tells you upfront: solar panels are the easy part. The real decision is HOW and WHERE you're going to mount them.

I've installed solar on three different RVs now, and I've seen it all—rooftop rigid panels, folding portable kits, flexible thin-film, and everything in between. Each approach has pros and cons, and I'm going to break them down for you.

Panel Types Explained

Before we get to specific products, let's understand what you're buying:

Rigid Monocrystalline (Best Overall)

Made from single-crystal silicon, these panels have the highest efficiency (20-23%). They're the gold standard for permanent RV installations. If you're serious about off-grid camping, these are your best bet.

Pros: Highest efficiency, longest lifespan (25+ years), best value over time

Cons: Heavy, requires permanent mounting, wind resistance on roof

Polycrystalline

Slightly cheaper but lower efficiency (15-17%). Fine for budget builds where space isn't a premium. You'll need more surface area to get the same wattage.

Flexible Thin-Film

Ultra-thin panels that conform to curved surfaces. Great for low-profile builds, but efficiency drops (15-19%) and lifespan is shorter (10-15 years).

Pros: Lightweight, low profile, conforms to curves

Cons: Lower efficiency, prone to delamination, shorter lifespan

Folding Portable Kits

Not mounted at all. Set them up when you park, store them inside when moving. Lower total output, but you can angle them at the sun.

Pros: No roof drilling, can optimize angle, easy to replace

Cons: Must set up/break down, can't leave unattended, storage space needed

Best Rigid Monocrystalline Panels

Renogy 100W Mono (Best Standard)

Price: $89-99 per panel

Dimensions: 42.2" x 19.6" x 1.4"

Efficiency: 21%

Why We Love It: Renogy is the de facto standard in the RV solar world. These panels hit the sweet spot of price, quality, and availability. I've got four of them on my roof, and they've survived three years of Texas sun without any degradation.

The MC4 connectors are universal, so they work with any charge controller. Customer support is actually helpful, which is rare in this industry.

Renogy 175W Flex (Best Flexible)

Price: $179 per panel

Dimensions: 59" x 26" x 0.1"

Efficiency: 18%

Why We Love It: Only 6 pounds and less than 1/4 inch thick. This is what you get if you want solar without the aesthetic of traditional panels. It sticks directly to your roof with adhesive (included).

I installed one on a friend's Class B van and it looks like it came from the factory. The trade-off is lower efficiency and you can't walk on it, but for the right application, it's perfect.

Rich Solar 100W Mono (Best Budget)

Price: $69-79 per panel

Efficiency: 21%

Why We Love It: Rich Solar offers nearly identical specs to Renogy at a lower price point. The quality control isn't quite as tight—expect slight variations in frame finish—but functionally, these panels perform great.

I've been running two Rich Solar panels for two years alongside my Renogy setup, and I honestly can't tell the difference in output. At $20-30 less per panel, the savings add up fast if you're buying 4+ panels.

Newpowa 100W Mono (Budget Alternative)

Price: $59-69 per panel

Efficiency: 20%

Why We Love It: The cheapest quality panel I've found. Newpowa doesn't have the brand recognition of Renogy, but the panels themselves are solid. Slightly smaller frame than competition, but the cells are the same quality.

Perfect if you're building a budget system and every dollar counts.

Best Folding Portable Kits

Renogy 200W Portable Kit (Best Overall)

Price: $449

Output: 200W (2x 100W panels)

Why We Love It: This is the kit I recommend to anyone who's not ready to commit to permanent installation. It includes everything: two 100W panels, a 20A PWM controller, alligator clips, and a carrying case.

Set up takes about 5 minutes. You can angle the panels independently to maximize sun exposure. When you're done, fold it up and store it in your basement storage or cargo bay.

EcoFlow 160W Portable (Best High-Tech)

Price: $549

Output: 160W

Why We Love It: EcoFlow makes the slickest portable solar gear on the market. The 160W panel folds down compact and has an adjustable kickstand for optimal angling.

What sets it apart: integrated carrying handle, premium build quality, and it's designed to work seamlessly with EcoFlow power stations. If you bought an EcoFlow Delta or River, this is the panel to get.

What Size Do You Need?

Here's a quick reference guide:

  • 200W: Weekend camping, phone/laptop charging, basic lights
  • 400W: Week-long dry camping, 12V fridge, some AC
  • 600W: Full-time boondocking, CPAP, multiple appliances
  • 800W+: Heavy usage, air conditioning, residential fridge

Common Mistakes

  1. Ignoring shading — Even partial shade kills output. Survey your roof before mounting.
  2. Wrong wire gauge — Undersized wiring loses power. Use a voltage drop calculator.
  3. Mismatched voltage — Make sure your panel voltage matches your charge controller input requirements.
  4. Cheaping out on mounting — Wind can rip panels off. Invest in proper mounting hardware.
  5. No maintenance plan — Clean panels quarterly for optimal output.

FAQ: RV Solar Panels

What is the best brand of solar panels for RVs?

Renogy is the most popular and reliable brand for RV solar, offering excellent warranties and customer support. For budget options, Rich Solar and Newpowa provide good value with slightly lower efficiency ratings.

Are flexible solar panels good for RVs?

Flexible panels are lightweight and low-profile, but have lower efficiency (15-18%) and shorter lifespans than rigid panels. They're best for curved roofs or aesthetic preferences.

How many solar panels do I need for my RV?

A typical RV uses 300-500Wh per day for basic needs. With 5 peak sun hours, 400W of panels generates about 2,000Wh daily. Start with 200W and add more as needed.

Can I walk on RV solar panels?

Most rigid panels are not designed to be walked on and can crack. Some industrial-grade panels can handle light foot traffic, but it's best to avoid stepping on any solar panel.
