Balcony Solar Black Friday Deals UK 2026

Black Friday deals on balcony solar in the UK arrive in November — and Black Friday 2026 is the first to fall after plug-in solar became legal in Great Britain on 27 August 2026. It is likely to be the best buying opportunity of the year, but the kit worth buying is the kit that is listed as compliant on the ENA G98 Type Test Register, which is not the same list as the brands you will see discounted.
Quick Facts - When Black Friday 2026 falls: 27 November 2026 - When deals typically start: Early November (EcoFlow and Anker typically run "early Black Friday" sales from the first week of November) - Typical discounts on solar kits: 20–40% off list price based on 2024–2025 patterns - The kits that can be self-installed: 84 devices from 21 manufacturers are verified compliant on the ENA G98 Type Test Register as of 30 September 2026 — City Plumbing, Perlight, Worldwide Solar, UKSOL, PatioSun, Zendure's SolarFlow 800, Octopus Energy, TSUNESS and others - The catch: the discount brands are now split by configuration, not by name. Anker is still not on the list at all. EcoFlow's solar-only plug-in kits became compliant on 22 Sept 2026 and Zendure's SolarFlow 800 on 21 Sept — but the battery bundles those brands discount hardest are still excluded and still need an electrician - Where to buy compliant kits: City Plumbing, Screwfix and Argos now stock listed kits, from £336 (single panel) or £444 (two panels) at City Plumbing - This page will be updated with live deals in November 2026 — bookmark it now
Why Black Friday 2026 Is Different
Every previous Black Friday in the UK occurred before plug-in solar was a legal, mainstream consumer product. There were no certified kits in shops, no established retail market, and no mass-market awareness. Black Friday solar "deals" were limited to European grey-market imports from a handful of specialist retailers.
November 2026 is different. By Black Friday: - Compliant UK kits will have been socket-legal for approximately 3 months (since 27 August 2026) - City Plumbing, Screwfix and Argos are already stocking ENA-listed kits, from £444 for a two-panel kit - EcoFlow, Anker, and Zendure — all established UK market players — run major Black Friday promotions annually
This is the first real UK Black Friday for balcony solar. Expect significant discounting as brands compete for the new mainstream buyer.
The Black Friday Trap: The Brands That Discount Are Not The Brands You Can Self-Install
This is the single thing to understand before you spend anything in November, and it is counterintuitive enough that most deal roundups will get it wrong.
Two separate lists matter:
The brands that discount hard on Black Friday: EcoFlow, Anker SOLIX, Zendure, Jackery. Household names, aggressive promotions, 20–40% off.
The brands listed compliant on the ENA G98 Type Test Register: City Plumbing (13 models), Perlight Solar (13), Worldwide Solar (10), UKSOL (7), PatioSun (6), Zendure (6, SolarFlow 800 only), Modular Solar (4), TSUNESS (3), Thunder Energy, The Solar Centre, Skyworth, APsystems, Hdm Solar, Solarfy, PowerXpress, Octopus Energy and others — 84 compliant devices from 21 manufacturers as of 30 September 2026 (of 101 records on the register).
Check the configuration before you trust a discount. An Anker Solarbank cannot be plugged into a socket by you — Anker holds no compliant plug-in listing. A discounted EcoFlow STREAM depends entirely on which box it is: the solar-only plug-in kit became compliant on 22 September 2026, but a bundle including a battery is excluded from the socket route and its mains connection must be hard-wired by a qualified electrician under BS 7671 — which typically costs £150–£400 and erases most of the discount you just captured.
Two structural reasons this gap exists:
- Battery-integrated kits are excluded from the socket route by the specification itself, regardless of testing. Almost every headline Black Friday product is battery-integrated. That is not a certification backlog that will clear by November — it is a design exclusion.
- Compliance attaches to the model number, not the brand. Anker created the AE1032Z1-20, factory-capped at 800W, specifically so one variant could register. Same brand, same product family, different legal status.
What this means for your Black Friday:
| If you want… | Buy | Expect |
|---|---|---|
| Socket self-install, no electrician | An ENA-listed kit from Argos, Screwfix, City Plumbing | Smaller discounts — these are trade retailers, not deal-season brands |
| Battery storage and smart energy management | EcoFlow / Anker / Zendure on deep discount | Budget £150–£400 extra for an electrician |
| The cheapest legal route | Entry-level listed kits | From £444 (two panels) before any Black Friday movement |
Check the certification tracker on the day you buy. Register entries have flipped status — Anker's AE1032Z1-20 was published compliant on 3 August 2026 and later changed to non-compliant.
What to Expect From Each Brand
EcoFlow — Historically the Most Aggressive Black Friday Discounter
EcoFlow runs the most extensive Black Friday promotion of any solar brand, typically spanning 3–4 weeks in November and discounting across its full product range. Based on 2024–2025 patterns:
- STREAM 800W bundle: Expected from ~£478 list price, likely discounted to £350–£420
- STREAM Ultra (with battery): Expected from ~£949 list price, likely discounted to £750–£850
- PowerStream bundles: 20–30% off list price
- EcoFlow batteries (Delta 2, River 2): Often discounted in conjunction with solar kit purchases
When to buy: EcoFlow typically launches its "early Black Friday" sale in the first week of November, with the deepest discounts running from approximately 20–27 November. Flash sales (24-hour or 48-hour) during this period can hit the deepest discounts of the year.
Where to buy: Direct from EcoFlow UK (uk.ecoflow.com) or Amazon UK. EcoFlow's direct store frequently offers slightly better deals than Amazon, plus bundle configurations not available elsewhere.
How to prepare: Create an EcoFlow account before November and sign up for their email newsletter — early Black Friday notifications go to subscribers first, and some "exclusive" discounts require being logged in.
Anker SOLIX — Deep Discounts on Premium Kit
Anker SOLIX runs major Black Friday promotions via Amazon UK and its own store. Based on 2025 European patterns:
- RS40P 800W bundle: Expected from ~£799–£999 list, likely discounted to £600–£750
- Solarbank 2 E1600 (with battery): Expected from ~£1,099–£1,299 list, likely discounted to £850–£1,050
Anker tends to run "doorbusters" — very limited stock at the deepest discount — in the first 24–48 hours of its Black Friday launch. These often sell out within hours.
Where to buy: Anker UK direct store (anker.com/uk) or Amazon UK. Anker's store frequently has bundle deals not listed on Amazon.
Zendure — Worth Watching for Battery-Integrated Systems
Zendure's Hyper 2000 and SolarFlow systems are the most sophisticated smart energy management options in the balcony solar market. If you're interested in time-of-use tariff optimisation or larger battery capacity, Zendure is the brand to watch.
- Hyper 2000 hub + 1.92kWh battery: Expected from ~£800–£1,000 list, likely discounted to £650–£800 during Black Friday
- Expanded battery modules: Often discounted individually during Black Friday, making it a good time to expand an existing system
Zendure's UK presence is smaller than EcoFlow's or Anker's, so deals are more likely through Amazon UK or specialist retailers like Bimble Solar than through a direct UK storefront.
Hoymiles — Best Budget Inverter Deals
Hoymiles does not run direct-to-consumer Black Friday sales in the UK. However, the inverters are widely stocked by Amazon UK third-party sellers and specialist solar retailers, and November typically sees competitive pricing on:
- HMS-800-2T: List price ~£100–£120; Black Friday prices likely £80–£95 from some sellers
- HM-400 single-input (for 1-panel builds): List price ~£65–£85; Black Friday prices likely £55–£70
Only useful for a hard-wired install. A separately bought inverter plus panels is not a certified kit, so it cannot use the plug-in socket route: it needs an electrician and a full G98 notification, and the electrician's fee outweighs any sale discount on the inverter. If you want to plug in yourself, buy a complete kit listed on the ENA register instead. Which Plug-In Solar Kits Are Certified?
Lidl and Iceland — Seasonal Pricing
Lidl and Iceland are unlikely to run traditional "Black Friday discounts" on their solar kits — their model is more fixed-price retail than promotional pricing. However:
- Lidl: May include solar kits in a Specialbuys promotion around the November period. Watch the Lidl Specialbuys page in late October for any indication.
- Iceland: Less established in solar; any Black Friday pricing would be opportunistic rather than planned.
Amazon Prime Day: The Earlier Alternative
If you don't want to wait until November, Amazon Prime Day — typically held in July — is the other major annual sale event for solar products.
For 2026 specifically, Amazon Prime Day is worth watching for solar because: 1. Compliant UK kits will have launched recently (socket-legal from 27 August 2026) 2. Amazon is a confirmed UK launch partner — Prime Day could coincide with or immediately follow the certification milestone 3. Prime Day typically runs for 48 hours with genuine discounts across the EcoFlow and Anker catalogues
Expected Prime Day solar discounts: 15–25% off list price — shallower than Black Friday but with less competition and no waiting until November.
How to Spot a Genuine Solar Deal vs a Fake Discount
Black Friday is a period when some retailers inflate list prices before applying a "discount" that returns the price to normal. Here's how to verify a solar deal is real:
Check CamelCamelCamel: For any Amazon listing, camelcamelcamel.com shows the full price history. A "60% off" claim on a product that has been at 60% off for the past 6 months is not a deal.
Compare with manufacturer RRP: EcoFlow, Anker, and Zendure publish RRPs on their UK websites. A Black Friday price below the manufacturer's own list price is a genuine discount.
Watch for bundle manipulation: "40% off when you buy panels + inverter + battery" can represent very different actual savings depending on what the "bundle price" was before Black Friday. Price the components individually before accepting a bundle deal.
Check warranty terms apply to UK sales: Occasionally, very deep discounts on Amazon apply to EU/US-spec products fulfilled from European warehouses. Confirm the listing shows "Sold by [UK retailer]" or "Ships from Amazon UK" and that the warranty is backed by the UK entity, not just a European parent company.

| Anker SOLIX RS40P 800W bundle | ~£799–£999 | £600–£750 |
| Anker Solarbank 2 E1600 (complete set) | ~£1,099–£1,299 | £850–£1,050 |
| Hoymiles HMS-800-2T (inverter only — electrician install) | ~£100–£120 | £80–£95 |
| Lidl kit (unconfirmed, not on sale) | ~£400 rumoured | No confirmed product |
| Zendure Hyper 2000 hub | ~£400–£500 | £320–£400 |
Best Balcony Solar Kits UK 2026
Is Black Friday Actually the Best Time to Buy Solar?
For most UK buyers, the answer is yes — with two caveats.
For summer installation: If you want your system generating through the summer peak (May–September), waiting until late November means missing 6 months of the best generating season. A system bought at £478 in April and generating £70 in summer savings would have paid £70 towards itself before Black Friday arrives. A 20% Black Friday discount saving £95 doesn't offset 6 months of foregone generation.
For winter/spring installation: If you're buying in autumn or winter with spring installation in mind, Black Friday is an excellent time. You're not missing high-generation months; you're buying the system at the lowest likely price of the year.
The break-even calculation: If Black Friday saves you £100 on a £500 system, and buying in April rather than November gives you 6 months of additional generation worth approximately £60, the Black Friday saving (£100) exceeds the foregone generation (£60). In this case, waiting is financially rational.
If the saving is £50 and the foregone generation is £80, buying earlier wins.
How Much Can You Save with Balcony Solar?
FAQs
Q: When do balcony solar Black Friday deals start in the UK? A: Typically early November — EcoFlow and Anker both start "early Black Friday" promotions in the first 1–2 weeks of November, with peak deals running from approximately 20–27 November. Black Friday itself falls on 27 November 2026.
Q: Which balcony solar brand has the best Black Friday deals in the UK? A: EcoFlow has historically run the deepest discounts and longest promotional windows. Anker SOLIX offers significant discounts but with limited-stock "doorbusters" that sell out quickly. Zendure is worth monitoring for battery-integrated systems. Hoymiles inverters don't see brand-direct sales but do see price competition on Amazon.
Q: Is it worth waiting until Black Friday to buy balcony solar? A: Only if you're buying in autumn or early winter. If you could install in spring (April–May), the additional generation you'd capture over summer likely exceeds the Black Friday saving. If you're buying for a winter installation, wait for Black Friday.
Q: Are Amazon Prime Day deals as good as Black Friday for solar? A: Usually shallower (15–25% vs 20–40%). Prime Day 2026 has now passed and predated the 27 August legalisation, so Black Friday is the first major sale event with the legal framework in place. See our dedicated tracker: Balcony Solar Amazon Prime Day Deals UK 2026
Q: What's the cheapest a decent balcony solar kit has ever been on Black Friday? A: Based on 2024–2025 European data (the UK market is new): EcoFlow PowerStream 800W bundles have hit around €350–€400 (~£300–£340) in European Black Friday sales. UK pricing may be slightly higher due to market-specific costs. The £350–£420 range for a STREAM 800W bundle in November 2026 is a realistic target.
