Pros and cons
✓ Pros
- Bends up to 258 degrees, so it follows a curved van or jeepney roof
- Only 2.3kg, around 70% lighter than a framed panel of the same output
- 23% efficiency, close to the rigid panels here
- Frameless and low-profile, so it sits flush and catches less wind
- Sold through EcoFlow's own Philippine Shopee store
✗ Cons
- No kickstand or carry case, so you cannot angle it at the sun the way a folding panel lets you
- Built for permanent mounting, which makes it the wrong panel to bring to a campsite
- Output drops on a curved surface because part of the panel always faces away from the sun
- EcoFlow does not publish an IP rating for this model, so treat the weatherproof claim as the listing's
The EcoFlow 100W Flexible is our Best for Curved Roofs pick: 100W that bends up to 258 degrees and weighs only 2.3kg, for around ₱8,000. It is made to be mounted once and left alone.
What is it actually for?
This is a panel for a curved surface. It bends to 258 degrees with a 200mm minimum arc radius, which covers a van roof, a boat cabin, a jeepney top, or a shed with a rounded profile. A framed panel simply cannot sit on those shapes.
At 2.3kg with no frame and no glass, it is around 70% lighter than a framed panel of the same output. On a vehicle roof that difference is not vanity, it is fuel and it is one person instead of two doing the install.
Efficiency is 23% from 182 monocrystalline cells, which is close to the rigid panels here and well ahead of the budget tier.
What is the catch?
It is not portable, and the word “flexible” hides that. There is no kickstand and no carry case. You cannot angle it at the sun. Once it is on a curved roof, part of the panel is always facing the wrong way, so real output sits below the 100W rating for most of the day.
If you want to carry a panel out, set it up, and aim it, you want a folding panel instead. This one is for a permanent install where you accept some loss in exchange for a shape nothing else fits.
The other gap: EcoFlow publishes no IP rating for this model. The lamination is built for outdoor use, but the weatherproof claim in the title is the listing’s word, not a documented figure.
Is it sulit?
Around ₱8,000 as of August 2, 2026. Check the latest price on Shopee. That works out to roughly ₱80 per watt, second only to the 125W Bifacial in this roundup, which is a genuinely good number for a specialist panel. Flexible panels usually carry a premium over framed ones. This one does not.
Sold through EcoFlow’s own Philippine Shopee store, which is the right channel for anything you plan to bolt to a vehicle.
Who should buy it
Buy this if you are mounting solar on something curved and it is staying there. It is the right choice for a van build, a boat, or a rounded roof where a framed panel will not sit flat. It is the wrong buy if you wanted something to carry to the province and prop up in the sun. 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 explains the difference between flexible and folding panels in more detail.
Alternatives to consider
If a flat surface will do, the EcoFlow 125W Bifacial is our Best Overall at around ₱9,000, with more output, 25% cells, and a documented IP68 rating. If you actually want to carry it, the EcoFlow 110W Portable Solar Panel Kit folds into its own kickstand case at around ₱15,000.

Frequently Asked Questions
How far does it actually bend?
Up to 258 degrees, with a minimum arc radius of 200mm. In plain terms it will follow the curve of a van roof, a boat cabin, or a jeepney top without cracking the cells. It is not a panel you roll up and put in a bag.
Is a flexible panel the same as a portable one?
No, and this is the mistake to avoid. Flexible means it conforms to a curved surface once mounted. Portable means it folds up with a kickstand so you can carry it and aim it. This panel has no stand and no case, so it belongs on a roof, not at a campsite.
Why is it so much lighter?
There is no aluminum frame and no glass. The cells sit in a glass fiber and lamination sandwich instead, which is what gets it to 2.3kg, roughly 70% lighter than a framed panel of the same output.
Is it waterproof?
EcoFlow does not publish an IP rating for this model, so the weatherproof wording is the listing's rather than a documented figure. The lamination is built for outdoor mounting, but if a stated rating matters to you, the 125W Bifacial and 110W panels both document IP68.
