Best Plug-In Solar Kits UK (2026): UKSOL Ranked by Real Value

Why this list is UKSOL-only right now

It would be easy to write a "best plug-in solar kits" roundup that name-checks EcoFlow, Anker, TSUNESS, FoxESS and half a dozen others, because plenty of that hardware is perfectly good kit. But this article ranks what you can legally connect to your home's electricity supply today, and that's narrower than the market suggests. The rule that makes any of this legal — SI 2026/848 — only removes the electrician and MCS-certification requirement if the specific microinverter model is listed as "Compliant" on the ENA G98 Type Test Register. As of our last check (26-28 August 2026), that register showed exactly eight compliant devices: UKSOL's seven kit variants and the Perlight PowerPlug MAX 465. Nothing else has cleared testing yet.

We've covered the legal mechanics in full in our plug-in solar legal explainer, and the pillar guide at our main plug-in solar hub covers the technology end to end. The short version: UKSOL isn't "the best" by some marketing measure — it's the only brand where every kit has actually finished G98 type testing and is confirmed compliant. That's the bar for this list, and it's the bar the law sets too.

Ranked comparison: all 5 UKSOL kits

All five kits share the identical 800W G98-compliant microinverter, anti-islanding protection, and the same registration process via myplugin.solar. The only real variables are DC panel wattage, mount type, price and — as a result — value per watt. We've ranked them by price-per-watt, the cleanest way to compare kits that all cap out at the same 800W AC export.

Two things jump out. First, the 1260W Pro Max is the standout on efficiency — more than double the panel wattage of the cheapest Compact for roughly 65% more money. Second, the 460W Compact is the outlier: priced close to the much larger 890W Duo despite barely a third of the panel area, making it the weakest deal in the range by some distance. If your space genuinely limits you to one small panel, it's still a legal, working kit — you're just paying a premium for the compromise.

For a vendor-neutral cross-check on these numbers, the certified-kit ledger at 800wsolar.co.uk lists the same kits with price, panel watts, mounting route and modelled payback in one sortable table, updated as retailer prices change.

UKSOL Pro Max 1260W

UKSOL Pro Max 1260W

The Pro Max is our overall winner and the kit we'd point most households toward, provided you have the wall, roof or ground space to fit its panel array. At 1260W of combined DC panel rating — comfortably under the 2,000W interim cap — it's the largest UKSOL kit sold through Argos. Because every kit uses the same 800W microinverter, the extra panel wattage over the Pro Plus mostly buys better output on overcast days and shoulder-season mornings, when a smaller array wouldn't reach the inverter's ceiling anyway. It's rated 8.8/10 in our own scoring, our highest mark in the range.

It's sold at Argos (listing 9837133) as a hybrid bundle that can go on a wall, sloped roof or ground mount, suiting both terraced houses with a usable rear wall and detached homes with garden space. The honest tradeoff is footprint: it needs the most physical room and it's the most expensive single purchase in the range, even though it's the best value per watt. If you've got a large south-facing wall or a garage roof going spare, this is very likely your kit.

UKSOL Pro Plus 1030W

The Pro Plus is our value runner-up, scoring 8.4/10, and it's the kit we'd suggest for anyone whose mounting space sits between "compact balcony" and "full garage wall." At 1030W of panel and the same 800W-capped microinverter as every other kit here, it still clips output on bright days, but reaches that ceiling more often across the year than the smaller kits, which is the practical benefit of buying more panel than the inverter strictly needs.

Argos lists it as 9973743 at £899, roughly £0.87 per watt — close behind the Pro Max and clearly better value than anything below it. It suits semi-detached and terraced homes with a decent side-return wall or a modest single-pitch roof, where the Pro Max's full array wouldn't fit. The tradeoff versus the Pro Max is modest: slightly less shoulder-season output for a £90 saving, a reasonable trade if space is tight rather than nonexistent.

UKSOL Pro Duo 890W

The Pro Duo sits in the middle of the range on price and panel count — as the name suggests, it's built around a two-panel layout that suits balcony rails and narrower walls better than the single large arrays on the bigger kits. At 890W for around £849 (Argos 9635335), it lands at roughly £0.95 per watt, fair but not exceptional next to the Pro Plus.

Where the Duo earns its place is mounting flexibility: two smaller panels split more easily across an awkward wall, a balcony balustrade, or a shed roof than one large panel would, a real advantage for flats and houses with fragmented outdoor space. The tradeoff is paying close to Pro Plus money for less wattage, so it only makes sense if the two-panel format solves a mounting problem the single-panel kits can't.

UKSOL Pro Compact 515W

The Pro Compact 515W is the cheapest way into UKSOL's range at £599 (Argos 9766802) — a sensible starting point if you just want to dip a toe in without a big up-front spend. Per-watt it works out at roughly £1.16, noticeably worse value than the Duo or Pro Plus, but it's also the smallest cash outlay in the lineup by £250 or more.

It's aimed at flats, small balconies and single-panel wall mounts where a bigger array was never an option regardless of price. The honest tradeoff: you'll clip the 800W inverter far less often, leaving headroom unused — you're buying the safety and legality of a G98-compliant system at the lowest price, not maximum output per pound.

UKSOL Pro Compact 460W

The Pro Compact 460W is the smallest kit in the range and, on the numbers, the weakest value: at roughly £849 (Argos 9593202) it costs almost the same as the 890W Pro Duo while delivering nearly half the panel wattage, working out at around £1.63-£1.85 per watt. We're including it for completeness and because there are genuine cases where it's the only kit that physically fits, but we can't recommend it as a value pick.

If your only viable spot is a single small wall panel or a narrow balcony rail, this is a legal, working option using the same compliant 800W microinverter as the rest of the range — it just costs a premium for that footprint. Anyone with a little more space should look hard at the 515W Compact or the Duo first, since both undercut it on price-per-watt while fitting comparably modest spaces.

Why we're not ranking EcoFlow, Anker or other brands

We want to be upfront about this rather than quietly leave rivals off the list. EcoFlow, Anker, TSUNESS, FoxESS, Octopus Energy's FoxESS-based filing, Segen and Modular Solar all show as "Non-compliant" on the ENA G98 Type Test Register as things stand. That word is doing important work: "Non-compliant" means testing or paperwork is unfinished, not that the hardware failed anything. There's no reason to assume these products are unsafe or badly built — several are established, well-regarded brands. But the register status is the legal gate, not a quality judgement, and until a model is marked "Compliant," plugging it in under the new interim rule is not lawful, however good the hardware turns out to be.

That's why this "best of" list only contains kits from one brand today. We'd rather publish an honest, narrow list than pad it with plausible-looking products you can't legally use yet. We're tracking the register and will update this article the moment anything else clears testing.

The same separation is applied by the 800wsolar plug-in solar ledger, which files kits awaiting certification apart from the ENA-listed ones instead of blending them into a single ranking. If any of these brands clears the register, that is where the change shows up first.

How to buy

Argos is the retailer with confirmed live UKSOL listings, and it's the source we've used for every price here. All five kits — Pro Max 1260W (9837133), Pro Plus 1030W (9973743), Pro Duo 890W (9635335), Pro Compact 515W (9766802) and Pro Compact 460W (9593202) — are listed as hybrid wall or balcony-mount bundles. Ground-mount-only versions are also available direct from uksol.uk from around £699, typically cheaper since you skip the wall-mount hardware.

UKSOL isn't currently sold through Amazon UK as a retailer listing, so our Amazon links point to a tagged search page rather than a dedicated product listing — an accurate reflection of where the brand sells today, not a broken link. eBay listings do exist from third-party sellers and are worth checking against the Argos price. Other retailers are expected to pick up the range as availability widens, but Argos is the only mainstream stockist we can confirm live as of publication.
