UKSOL Plug-In Solar Kits Compared: Full Spec Table (2026)

The short version: one inverter, five panel sizes

Since SI 2026/848 took effect on 27 August 2026, "plug-in solar" — a panel plus a microinverter that plugs into a normal 13A socket — has been legal in the UK without an electrician or MCS certification, provided the microinverter is listed as "Compliant" on the ENA G98 Type Test Register. As of 28 August 2026, UKSOL Ltd is the only brand with kits fully cleared on that register, and it has seven in total. Five of those are retail hybrid wall/balcony-mount bundles sold through Argos; the rest are smaller ground-mount-only variants sold direct via uksol.uk.

Here's the thing that simplifies this whole comparison: every UKSOL kit uses the identical 800W AC microinverter. Nothing about the electrical side changes as you move up the range. What changes is the panel side — the DC wattage feeding into that inverter, which ranges from a single 460W panel right up to two 630W panels wired together for 1,260W. All of it sits comfortably under the interim 2,000W DC cap set out alongside SI 2026/848, so headroom isn't really a factor here — space, budget and mounting are. This piece is the spec-table companion to our best plug-in solar kits ranking; if you want the "should I even do this" framing and our overall pick, read that first. Here we go deeper on the hardware itself: panel counts, wattages, mount types and exactly how the numbers stack up kit by kit.

Full spec comparison: all five UKSOL kits

All five retail kits below are hybrid wall/balcony-mount bundles, meaning the panel frame is designed to fix to an exterior wall, a balcony rail, or a similar vertical or angled surface, and every one ships with the same 800W AC microinverter. The only variables are how many panels you get, their combined wattage, and price. We've calculated price-per-watt (Argos price ÷ rated wattage) for each so you can see where the value actually sits.

Work through the maths and a pattern jumps out immediately: the two-panel kits are consistently better value than the single-panel Compact kits. The Pro Max 1260W comes out at £989 ÷ 1,260W = £0.78 per watt, the cheapest of the range by some distance. The Pro Plus 1030W is £899 ÷ 1,030W = £0.87/W, and the Pro Duo 890W is roughly £849 ÷ 890W = £0.95/W. Compare that with the Pro Compact 515W at £599 ÷ 515W = £1.16/W, and especially the Pro Compact 460W at roughly £849 ÷ 460W = £1.85/W — over double the per-watt cost of the Pro Max. That's not a pricing mistake; the Compact kits exist for tight balconies and small wall sections where a two-panel array simply won't physically fit, and UKSOL prices them for the space they solve rather than for outright value. If you have the wall or balcony real estate for a bigger array, the bigger kits are the better buy per watt every time. For the fuller savings maths on what any of this actually knocks off a typical bill, see our running costs and savings breakdown.

Whichever kit you land on, two admin steps are non-negotiable under SI 2026/848: register the installation at myplugin.solar, and notify your electricity distribution network operator (DNO) within 28 days of switching it on. Neither step involves an electrician visit for a compliant kit like these, but skipping them puts you outside the legal framework the new rules created.

For an independent cross-check of these specs and prices, the 800wsolar certified-kit ledger carries the same seven UKSOL entries plus the Perlight PowerPlug MAX 465, with prices checked manually against retailer listings.

UKSOL Pro Max 1260W: the biggest array, the best value per watt

The Pro Max 1260W is the flagship of the range: two 630W TOPCon N-Type bifacial panels wired into the standard 800W AC microinverter, for a combined DC rating of 1,260W feeding through the same 800W AC ceiling every other kit shares. Bifacial cells can pick up reflected light off a light-coloured wall or balcony surface behind them, which can nudge output on top of the front-facing generation, though how much depends heavily on your specific mounting surface and orientation. It mounts via the hybrid wall/balcony bracket system, so it suits a house with a decent run of south-or-near-south-facing exterior wall, or a flat with a wide balcony that gets clear sun for most of the day. At £989 (Argos product 9837133), it works out at £0.78 per watt — the best value of any kit in the range — because you're spreading the fixed cost of the microinverter, cabling and bracket hardware across the most panel wattage. This is the kit for anyone with the space who wants to maximise generation from a single plug-in socket.

UKSOL Pro Plus 1030W: nearly as much panel, a chunk cheaper

The Pro Plus 1030W drops down to two 515W TOPCon N-Type bifacial panels, still on the same 800W AC microinverter, for 1,030W of combined DC capacity. It's the same hybrid wall/balcony mount hardware as the Pro Max, just sized for a slightly smaller footprint — useful if your wall run or balcony width can't quite accommodate the larger 630W panels side by side. At £899 (Argos product 9973743) that's £0.87 per watt, still comfortably ahead of the two Compact kits and only a few pence per watt behind the Pro Max. It suits households who want most of the generation benefit of the flagship kit without quite the same panel footprint or upfront spend.

UKSOL Pro Duo 890W: the mid-range compromise

Two 445W panels make up the Pro Duo 890W, again paired with the identical 800W AC microinverter. It's the smallest of the two-panel kits, which makes it a reasonable fit for narrower balconies or a shorter stretch of usable wall where the Pro Plus's 515W panels would be a squeeze. At around £849 (Argos product 9635335) it comes out at roughly £0.95 per watt — still notably better value than either single-panel Compact kit, and this is the kit we've picked as our runner-up overall for balancing generation, price and mounting flexibility. If the Pro Max or Pro Plus don't physically fit your space but you still want two panels rather than one, this is the sensible landing point.

UKSOL Pro Compact 515W: one panel, smallest footprint that still moves the needle

The Pro Compact 515W is a single 515W panel on the same 800W AC microinverter — effectively half of the Pro Plus kit's panel array, in one unit rather than two. The hybrid mount hardware is scaled down accordingly, which makes this the kit to reach for on a narrow balcony, a small flat-facing wall panel, or anywhere a two-panel array simply won't physically go. At £599 (Argos product 9766802) it's the cheapest kit in cash terms and works out at £1.16 per watt — worse value than any of the two-panel kits, but this is a kit bought for fitting a constrained space rather than for maximising watts per pound.

UKSOL Pro Compact 460W: smallest panel, priced for the tightest spaces

The Pro Compact 460W is the smallest panel in the range at 460W, still driving the same 800W AC microinverter as every other kit here. Confusingly, it's priced higher than the larger Pro Compact 515W — at around £849 (Argos product 9593202) it works out at roughly £1.85 per watt, by far the weakest per-watt value in the entire lineup. That's not a typo on our part; it genuinely prices out worse than kits with twice the wattage. Only buy this one if the 515W Compact's slightly larger panel won't physically fit your mounting spot — this is a kit for a very specific tight-space scenario, not a value pick under any circumstance.

Don't need the wall bracket? The ground-mount-only alternative

All five kits above come with hybrid wall/balcony mounting hardware, which adds cost. If you've got a garden, patio or flat roof area where a ground-standing frame will do the job instead, UKSOL also sells ground-mount-only versions direct via uksol.uk, without the wall/balcony bracket kit bundled in. These start from about £699 for the smaller panel sizes and run up to around £1,199 for a Pro Duo 890W ground-mount bundle that includes two-person delivery given the extra weight of a full ground frame and two panels. These are a distinct SKU and price track from the Argos hybrid-mount bundles covered above — same underlying 800W AC microinverter and panel technology, but without paying for wall-fixing hardware you won't use. If your only viable install spot is a lawn, decking or a flat roof rather than a vertical wall or balcony rail, it's worth checking uksol.uk directly before defaulting to the Argos hybrid bundles, since you could save on mounting hardware you don't need. For more on how the wider plug-in solar category compares across mounting styles, see our plug-in solar panels UK guide.

Buying logistics: where these kits are actually sold

All five hybrid-mount kits are live now through Argos, which is currently the only major UK retail route to buy a G98-compliant plug-in solar kit off the shelf. One thing worth flagging clearly: UKSOL kits are not sold on Amazon UK. Where you see Amazon links on this page and elsewhere on the site, they're tagged searches pointing at the UKSOL product name on Amazon's marketplace, not direct product listings — that's intentional, not a broken link, and reflects the fact that UKSOL has chosen Argos and its own direct site (uksol.uk) as its retail channels rather than Amazon. eBay links work the same way, pointing to live marketplace listings under the model name rather than a single fixed product page. If you're comparing this against other routes to market, our best plug-in solar kits ranking covers all seven UKSOL kits side by side, including the two we haven't detailed in the spec table above.

Whichever kit and retailer you buy through, the legal obligations sit with you as the installer, not the retailer: confirm the specific model is still listed as "Compliant" on the ENA G98 Type Test Register at the time you buy (the register can change), register the finished installation at myplugin.solar, and notify your DNO within 28 days of switching it on. None of that requires an electrician visit for these compliant kits, but all of it is required to stay inside SI 2026/848 rather than outside it.

Stock and pricing across these kits move week to week; the 800wsolar ledger records the current list price per kit and dates each update, which is the quickest way to spot a change before you order.
