Rank #6 in Best Solar Panels 2026: 10 Ranked, and Where the Wattage Doesn't Add Up
ECO-WORTHY 400W Flexible Solar Panel Kit (2 x 200W)
Price and rating as shown on Amazon when we collected them. Both change.
ECO-WORTHY's 400W flexible kit came in at #6 in our guide to solar panels. It is a flexible two-panel set using N-type cells with an 18-busbar layout and an all-black finish, listed at £249.99 with 4.6 out of 5 from 7 Amazon ratings.
The headline figure and the specification field are not the same figure. The title says 400W and 2PCS 200W, while the specification table says "Maximum Power: 200 Watts" — 200W is one panel, and it is the pair that would get you to 400W. The same listing says "Number of Items: 2" but also "Unit Count: 1.0 count" and "Included Components: 200W Flexible Solar Panel", in the singular. At the listed price, £249.99 against a claimed 400W works out at 62.5p per watt; if only 200W is what turns up, the same money is £1.25 per watt. One reviewer reports the pair making "over 320w" lying flat in a garden, without angling them. Everything on this page comes from the Amazon listing for this product, not from any testing by us.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Wanted 300w or more in one panel, what a mine field of total dishonest info there is. Although a glass panel was cheaper and over 500w the weight was going to add to much to a RV roof. decided to try these wasn't expecting the quality and performance to be much.Tested flat in the garden charging a battery power st without trying to position and angle for best performance the pair made over 320w and easily charged the power st.Its a sunny day and planning the layout on the RV roof they did get really hot to handle, so looking at mounting and trying to keep some airflow around them .”
Verified purchase“Good value with voucher price £100.The panel looks well designed and is noticeably lighter than my old 100W foldable panel. However, I'm slightly concerned about the cable junction box mounted on the top side, as it could be a potential durability issue over time. That said, the 5-year warranty provides reassurance, and I assume the junction box is manufactured from UV-resistant material with a weatherproof seal to prevent water ingress and protect the internal structure during long-term outdoor use.”

Questions people ask
How many panels does the ECO-WORTHY kit contain?
The listing says "Number of Items: 2" and the title says 2PCS 200W, but "Included Components" reads "200W Flexible Solar Panel" and "Unit Count" reads "1.0 count", so the pack count is only unambiguous in the title.
What does the specification table say the maximum power is?
It says "Maximum Power: 200 Watts" for model L02AM200HJT2-2, while the title and the two-panel count are what produce the 400W figure.
What output does the listing claim per day?
The Item Highlight field reads "1.6kWh/day", stated without any conditions or test method.
What efficiency do the cells claim?
The ECO-WORTHY bullets claim up to 25% conversion efficiency from N-type cells, with ETFE material quoted at over 95% light transmittance.
How are the panels fitted?
Each ECO-WORTHY panel has 6 pre-drilled rust-resistant metal grommets and comes with 6 stainless steel zip ties; the listing also says the back of the panel can be glued.
Does it protect the battery at night?
Yes — the listing states a built-in blocking diode prevents reverse current so the battery does not discharge through the panel in low light.
