EcoFlow 100W Flexible Solar Panel Review – Straight from the Road with Power Nomad

G’day legends, it’s your mate Power Nomad here – the kiwi van lifer who’s clocked more kilometres on gravel roads than most people have on motorways. Between chasing sunsets in the Mackenzie Country and hiding from horizontal rain on the West Coast, I’ve learned one hard truth: your solar setup can make or break the off-grid lifestyle. Today I’m reviewing the EcoFlow 100W Flexible Solar Panel – a panel I’ve been running on my van for the last few months.

First Impressions: Built for Real Nomads

This thing is properly lightweight at just 2.3kg (5.1 lbs). That’s 70% lighter than a traditional rigid 100W panel, which makes a massive difference when you’re climbing on the roof with tools in hand or trying to reposition it.

It’s thin, bendy (up to 258° of flex), and feels surprisingly tough with its glass fibre lamination and IP68 waterproof rating. Pre-cut eyelets and a decent length of cable (about 1m) make installation straightforward. I mounted mine semi-permanently on the slightly curved section of my van roof using heavy-duty adhesive and some extra stainless fixings for peace of mind in high winds.

Real-World Performance on the Road

In New Zealand conditions, this panel performs well for its size and flexibility. On a clear summer day I’ve seen peak outputs around 75-85W in optimal conditions, and it still pulls 30-50W on partly cloudy days. That’s solid for a flexible panel – though expect 10-25% less than a rigid panel of the same rating due to the technology.

Paired with my EcoFlow Delta, it’s been brilliant for maintaining my system while driving or parked up. It loves partial shading better than some panels thanks to the bypass diodes, which is handy under trees or when part of the roof is blocked.

Key Specs for Nomads:

Rated Power: 100W (±5W)

Efficiency: 23% (excellent for flexible)

Open Circuit Voltage: 20.3V

Short Circuit Current: 6.3A

Max Operating Voltage/Current: 17.1V / 5.9A

Dimensions: 1055 × 612 × 25 mm

IP68 waterproof & dustproof

Works great with EcoFlow power stations (plug-and-play) and most MPPT controllers

What I Actually Loved

Curved surface champion — Fits perfectly on van roofs, boat decks, or wherever a rigid panel would rock or create wind drag.

Ultra-portable — Easy to take off and lay flat on the ground or lean against the van for better sun angle when stationary.

Tough as nails — Survived heavy rain, dust from central Otago, and strong coastal winds without drama.

Low profile — Almost invisible on the roof and adds almost zero height or wind resistance – perfect for those sneaky low-clearance camp spots.

Quiet and zero maintenance so far.

The Nitpicks

Output vs rigid — It’s never going to match a rigid panel watt-for-watt in the same conditions. If you’ve got flat roof space, rigid might give you more bang for buck.

Price — It’s a premium product. You’re paying for the lightweight flexibility and EcoFlow ecosystem integration.

Adhesive mounting is semi-permanent; removing it cleanly can be tricky if you change your mind.

Final Verdict from the Van

If you’ve got a curved roof, weight restrictions, or want a low-profile setup that doesn’t scream “solar van” to every car park ranger, the EcoFlow 100W Flexible Solar Panel is an excellent choice. It’s not about maximum raw power – it’s about practical, reliable solar that actually fits your nomadic life.

For solo or couple van lifers in NZ, one or two of these (in parallel) combined with a good battery setup keeps the lights on, the fridge cold, and the laptop charged without drama. It plays beautifully with the rest of the EcoFlow ecosystem too.

Would I buy it again? Absolutely. It’s earned its place on the roof.

Stay sunny and keep exploring,

– Power Nomad

Rating: 8.7/10

(Drops a bit for the price and slightly lower output than rigid equivalents, but wins big on practicality and build quality for real-world van life.)
