About Balcony Energy
Why this site exists
Balcony solar — plug-in solar panels that generate electricity without a roof install — has been huge in Germany, the Netherlands, and across central Europe for years. The UK has been slow to catch up, partly because the regulatory picture was murky and partly because almost all the good information was in German.
That's changing fast. In March 2026 the UK government took the first steps toward formally legalising plug-in solar systems under 2kW, and a BSI standard is expected by mid-2026. Manufacturers are now stocking UK-spec inverters, Amazon UK carries dozens of kits, and renters and flat-dwellers across the country are quietly cutting their electricity bills without asking their landlord's permission.
We built BalconyEnergy.co.uk because we couldn't find a single good, honest, UK-specific resource that answered the real questions — not "is solar good?" but "can I actually do this in my rented flat in Manchester, and will it pay back?"
What we cover
- Guides — practical, step-by-step explanations of how balcony solar works, what to buy, and how to install it
- Reviews — independent assessments of every major kit available in the UK, from EcoFlow and Anker to Lidl and Aldi
- Legal & DNO — plain-English answers to the regulatory questions: G98 notification, leasehold consent, insurance, renter rights
- Savings calculator — a real calculator using EU PVGIS satellite data and your actual postcode, not rough regional averages
How we research
We research products using publicly available specifications, independent test data, manufacturer documentation, and user reviews from verified purchasers. We do not accept free products in exchange for coverage, and we do not accept payment for positive reviews or rankings.
Where we earn affiliate commission (see our full disclosure), this never influences what we recommend. We recommend products we would buy ourselves — or tell you clearly when we wouldn't.
A note on accuracy
The UK balcony solar market is moving quickly. Regulations, product availability, and prices change. We update articles when we become aware of material changes, but we cannot guarantee everything is current at the moment you read it. Always verify critical information — especially legal and technical details — with the relevant authority before making decisions.
Nothing on this site is professional financial, legal, or technical advice.
Who writes this
Articles on Balcony Energy are written and maintained by Rowan Halstead, the site's lead researcher. Rowan's background is in data analysis and computer vision, and that shapes how this site works: we treat manufacturer claims as things to be tested, not repeated. We build our own tools — the savings, payback, and DNO checkers on this site are ours — and we go to primary sources, reading ENA and DNO engineering documents, Ofgem price-cap notices, and gov.uk consultations directly rather than relying on other blogs.
We are not qualified electricians, and we say so plainly whenever a question genuinely needs one. Where we can point to real, first-hand generation data we do; where we are working from published specifications or other owners' reported figures, we label it as such. The aim is simple: be the source we wish had existed when we started looking into this.
