Contents
A kit is listed as plug-in only when the seller's own page says it connects with a 3-pin or 13A plug into a socket. Systems that their sellers describe as hardwired are listed apart: they can be good products, but they are not the plug-in route. Prices include VAT and are those shown on 14 November 2026, during Black Friday sales: check the seller before you buy.

How we compare: criteria, sources and dates
How we pick
- Only plug-in kits with panels count, with a price we could read on the seller's page.
- Each pick is the cheapest kit that meets its condition; a kit already picked is skipped. Commission plays no part: no seller had accepted Socket Sun into an affiliate programme on 14 November 2026.
- "Cost per kWh" uses London, south-facing, tilted at 35°, from PVGIS, after the 800 W cap [calc]. Try your own town in the calculator.
What to check on any kit
- Is it on the ENA register? Your DNO points buyers to the ENA Connect Direct register (type Plug-in Solar), which listed 164 devices on 14 November 2026, some marked non-compliant.
- Watts: output is capped at 800 W whatever the panels; panels above 960 Wp come with advice to have your wiring checked first (specification, 4.1).
- Mounting: balcony, wall or ground brackets are often sold as separate versions, at different prices, and some are sold out.
- Delivery: Octopus ships two-panel bundles on a pallet of about 112 kg, kerbside; Zendure's kit was on a 50-day pre-sale.
Seller-page inconsistencies we noticed
City Plumbing's "DMEGC 475W" kit lists two 465 W panels and a HiFlow 800 Pro in its "What's included" text, and the "1050W PRO" kit describes a single 525 W panel. We show the watts in the product titles; ask the seller before ordering.
Head-to-heads: Octopus vs Zendure, EcoFlow STREAM vs Anker SOLIX, one panel or two.
Frequently asked questions
Which EcoFlow kit is plug-in in the UK?
On 14 November 2026, EcoFlow UK's STREAM 800W Microinverter Kit page said that in the UK its cable must be connected to the distribution board by a professional installer or electrician, and the STREAM batteries are supplied with stripped-end cables for hardwiring. We therefore list them as hardwired, not plug-in.
Does Anker SOLIX sell a plug-in kit in the UK?
We found the Solarbank 4 E5000 Pro on Anker SOLIX UK, which the page says must be hardwired by a Part P electrician because the plug-in framework covers solar-only systems. We did not find a solar-only plug-in kit on the UK store on 14 November 2026.
Is BLUETTI selling plug-in solar in the UK?
We searched BLUETTI's UK store and its product sitemap on 14 November 2026 and found no balcony or plug-in solar kit, only power stations, home backup batteries and panels.

- EcoFlow STREAM vs Anker SOLIXTwo solar batteries sold in the UK, compared on their own pages. Neither is sold as plug-in: here is what that means for you.
- Octopus vs ZendureTwo 920 Wp plug-in kits with a 3-pin plug, £149 apart on 14 November 2026. Same panels' watts, so the same kWh: the difference is price, inverter and delivery.
- One panel or twoThe second panel doubles what the kit makes. It does not double what you save, unless your home uses it.
- Adding a batteryNot on the plug-in route, for now. And the sums show why it matters less than you might think with 800 W.
