Rank #4 in Best Solar Panels 2026: 10 Ranked, and Where the Wattage Doesn't Add Up
DOKIO 200W Solar Panel Kit with 20A Controller
Price and rating as shown on Amazon when we collected them. Both change.
The DOKIO 2PC kit takes fourth place in this guide. It is a two-panel monocrystalline set supplied with a charge controller, priced at £116.99 and rated 4.4 out of 5 from 420 ratings. It is also the listing that shows the guide's central point most plainly: the power in the title and the power in the specification field are two different lines, and you have to read both.
The title says 200W. The specification field says Maximum Power: 100 Watts, and a separate field says Number of Items: 2 — so the 200W is two 100W panels, not one panel rated at 200W. Put the other way, £116.99 divided by the 200W the title names works out at roughly 58p a watt, mid-range against the 41p to 98p spread across this guide. The controller line is the stranger one: the title advertises a 20A controller while the Amperage Capacity field reads '20 Milliamps', which is 0.02A. Both figures appear in the same listing without explanation. Everything on this page comes from the Amazon listing — nothing here is from our own testing.

Questions people ask
Is this a 100W kit or a 200W kit?
Both figures come from the same listing. The title says 200W, while the specification field says Maximum Power 100 Watts and a separate field says Number of Items 2 — so the 200W described in the title is two 100W panels.
What size controller is included?
The title advertises a 20A controller, and the Amperage Capacity field reads 20 Milliamps, which is 0.02A. The DOKIO listing shows both numbers and does not explain the difference.
How much does the DOKIO kit cost?
It is listed at £116.99.
How is it rated by buyers?
4.4 out of 5 from 420 ratings. Of those, 71 are 5-star, 17 are 4-star, five are 3-star, two are 2-star and five are 1-star.
What is it made of and how much weather can it take?
Monocrystalline silicon in a corrosion-resistant aluminium frame, described as waterproof, rated to withstand high wind of 2400Pa and snow loads of 5400Pa. The listing gives the weight as 5.3 kg.
How does it connect and mount?
MC4 connectors, and the listing says four mounting holes are available to attach fasteners. DOKIO lists it as suitable for RV, camping, off-grid systems, caravan, boat and greenhouse use.
