A day in the life of an 800W kit

The sun arcs east to west across the sky. The panel charges as it climbs and dims as it sets. Loops every 8 seconds.

Why This Matters Now

The UK is opening up plug-in solar

The BSI plug-in solar product standard is expected July 2026, and the government has confirmed kits are coming to UK shops this year. The compliant route to install in 2026 remains a CPS-registered electrician with a hardwired connection: BS 1363 (UK 13A plugs and sockets) and BS 7671 (wiring regulations) do not currently authorise plugging small generators into a wall socket. Update: Ed Miliband confirmed on 21 April 2026 that the government is "absolutely motoring" on getting kits into UK shops. New here? Start with our plug-in solar explainer.

BSI product standard expected July 2026

BSI's forthcoming product standard will certify specific plug-in solar kits as safe products. It does not by itself amend BS 1363 or BS 7671, so plug-in via a 13A wall socket is not made compliant by the BSI standard alone. The compliant install route remains a CPS-registered electrician.

Kits available now on Amazon

EcoFlow STREAM systems are shipping to UK addresses today. Panels, inverter, and mounts in one box from £499.

Renters protected by law

Under the Renters' Rights Act 2025, landlords cannot unreasonably refuse a portable plug-in system. See renter protections in our guide.

Proven across Europe

London's mixed skies don't stop solar generation. Panels produce electricity from daylight - not direct sun - just like the million+ balcony systems running in Germany's similar climate. Learn how we track the sun position for accurate UK savings estimates. Photo: Miguel Rivera via Pexels

BSI Standard Watch

The BSI plug-in solar product standard is expected July 2026. It is a product specification only. The compliant install route in the UK remains a CPS-registered electrician with a hardwired connection from around £250.

How It Works

Three steps to your own electricity

The compliant route in the UK is a CPS-registered electrician with a hardwired connection. Typical install time is around two hours and costs from £250.

Buy a kit

Order an EcoFlow STREAM kit online. A complete 800W system includes two panels, a microinverter, and mounting hardware - from £499. Compare the best plug-and-play options.

Mount and connect

Attach panels to your balcony railing, garden fence, or south-facing wall. A CPS-registered electrician then hardwires the system into your consumer unit. This is the compliant UK route today, and the BSI plug-in solar product standard expected July 2026 does not by itself change BS 1363 or BS 7671.

Generate and save

Your system feeds electricity into your home, offsetting what you'd draw from the grid. Watch your bill drop. Understand balcony solar as part of energy resilience.
