Pros and cons

βœ“ Pros

  • Rated for winds up to 130 mph, which matters in a typhoon belt
  • Anti-corrosive aluminum frame built for years of outdoor mounting
  • 23% efficiency from monocrystalline cells
  • IP68 rated, designed to stay outside permanently
  • Sold through EcoFlow's own Philippine Shopee store

βœ— Cons

  • 21.8kg and over 1.7m long, so it is a roof or ground-mount panel and not portable in any real sense
  • No kickstand or carry case, so mounting hardware and wiring are on you
  • The rigid frame cannot be stowed in a car boot the way the folding panels here can
  • Costs more per watt than the folding 400W panel while being far harder to install

The EcoFlow 400W Rigid is our Best for Permanent Install pick: 400W rated for winds up to 130 mph, for around β‚±40,000. Understand before anything else that this one is not portable.

What makes it a permanent panel?

Weight and frame. 21.8kg, 1,722 x 1,134 x 35mm, with an anti-corrosive aluminum frame and no kickstand or carry case. This is a panel you bolt down once.

What you get in exchange is durability built for the outdoors in a way a folding panel is not. IP68, a frame designed to resist corrosion in salt air, and a 130 mph wind rating. In a country that takes twenty typhoons a year, that last number is the reason this panel exists.

Efficiency is 23% from monocrystalline cells, with an open circuit voltage of 37.10V.

What is the install actually like?

Plan for it properly. The panel ships with a 300mm charging cable and nothing to mount it with. You will need brackets or rails, wiring, and either a charge controller or a power station whose solar input can take it.

It is a two-person lift onto a roof. If that sentence gives you pause, this is the wrong panel and the folding 400W is the right one.

Is the EcoFlow 400W Rigid sulit?

Around β‚±40,000 as of August 2, 2026. Check the latest price on Shopee. That is β‚±100 per watt, which is more than EcoFlow’s folding 400W panel asks at roughly β‚±88 per watt, and the folding one can also be moved.

So the value case rests entirely on the install. If the panel is going on a roof permanently, the rigid frame and the wind rating are worth paying for and the folding panel’s kickstand is wasted on you. If there is any chance you will want to move it, the comparison goes the other way and it is not close.

Sold through EcoFlow’s own Philippine Shopee store, which matters for a product this size, because a warranty claim on a 21.8kg panel is not something you want routed through a reseller.

Who the EcoFlow 400W Rigid suits

Buy this if you are mounting solar on a roof or a ground frame and leaving it there for years. It is the right choice for a house, a farm shed, or a small off-grid setup in a storm-prone area. It is the wrong buy if you want to carry it anywhere. See how it ranks in our best solar panels in the Philippines roundup, or browse more on our Home Improvement page. Our solar panel buying guide covers rigid versus folding panels.

If the EcoFlow 400W Rigid is not right

For the same 400W you can actually move, the EcoFlow 400W Lightweight Portable folds and costs less at around β‚±35,000. For a much smaller permanent install, the EcoFlow 125W Bifacial is our Best Overall at around β‚±9,000 and also carries an aluminum frame and IP68.

Frequently Asked Questions

Can I carry this one around?

No. At 21.8kg and over 1.7m long with a fixed aluminum frame, this is a two-person lift and it does not fold. If you want 400W you can move, EcoFlow's folding 400W panel is the one to look at instead.

Why does the wind rating matter here?

Because of where we live. The panel is rated to withstand winds up to 130 mph, which is the kind of number worth checking before you bolt anything to a roof in a typhoon belt. It is the single strongest reason to pick this over a folding panel for a permanent install.

What else do I need to buy?

Mounting hardware and wiring, at minimum, and most likely a charge controller or a compatible power station input. The panel ships with a 300mm charging cable and nothing to attach it to a roof, so budget for the install as well as the panel.

Is 23% efficiency good?

It is solid for a rigid framed panel, though slightly below the 25% that EcoFlow's newer TOPCon panels reach. On a permanent roof install efficiency matters less than it does on a portable panel, because you can simply add area.
