Independent reading, ordered most-recent first. Standards updates, calculator methodology, kit comparisons, and the renter angle other UK solar coverage misses.
Each piece is dated, sourced and revised when the underlying standards or numbers change. For ongoing changes, see the changelog.
The cheapest approved kit makes electricity at 2.4p per unit over twenty years, or 4.9p counting only what you use rather than export. The grid charges 26.32p. Costed per kit and per mounting position, and it exposed a fault in our own calculator.
Register watchYes, since 8 September 2026. Octopus is the first energy supplier with a device on the ENA register, and it cleared roughly three weeks before its own first deliveries. £450 for one panel, £650 for two, and what that signals for prices.
RegulationsA rule nobody mentioned on launch day: in England, plug-in solar drops out of permitted development the moment any part of it is fixed to timber. Not a ban, but it means a planning application. The SI, the reasoning, and what to do instead.
NewsDay one had seven approved kits from one maker. Three weeks later there are forty-eight from thirteen, and the cheapest compliant kit has fallen to £432. The prices, the per-watt maths and what is still missing.
NewsThe network-side rule is signed off. From 27 August you connect a compliant kit yourself and notify your DNO. What it means for buyers: one per home, simplified forms, and BS 7671 still applies.
NewsUp to 96% of the Sun goes dark over the UK on Wednesday evening. What it does to a plug-in system, the 90-percent misconception, the safety facts, and why it is a Europe-wide grid event, not just an astronomy one.
NewsWe finally have a date. What actually changes that morning, why I think the kit lands faster than most people expect, and what Germany's registration numbers tell us about what happens next.
NewsThe government has confirmed it is going ahead. The PSSR and ESQCR amendments, the G98 change and the final Interim Product Specification, decoded, plus the honest answer on whether you can plug one in yet.
AnalysisThe UK battery boom is racing ahead at grid scale first, because the grid can already pay batteries for flexibility. Why the big batteries win, what is slowing home batteries, and what households can borrow from them.
Market noteI photographed EcoFlow and Jackery on the pallets in a UK Costco on 1 July 2026. What the retail shift means for buyers, the one accuracy line that matters, and how it maps onto Germany's balcony solar boom.
NewsThe 16 June 2026 consultation proposed a PSSR amendment and an Interim Product Specification, not the BSI route we expected. It led to SI 2026 No. 848, which makes plug-in solar legal from 27 August 2026.
AnalysisTwo batteries, same capacity, eight hours apart on fridge runtime. A plain-English look at idle draw, the Anker C2000 Gen 2 vs EcoFlow Delta 3 Max test, and why it matters for solar owners.
NewsThe 9 June 2026 joint statement from ECA, Electrical Safety First, the IET, NICEIC and SELECT, what it says, what it does not, and why it is the cautious line this site has held.
InvestigationGermany's Solarpaket I journey to 1M+ balcony installs, the UK position in May 2026, and what EcoFlow's UK product page signals about the regulatory direction.
NewsStanding charge 54.74p, unit rate 25.07p, April usage 137.33 kWh. I work the rise on my own bill, then look at where plug-in solar and the new rules fit.
NewsThe 21 April 2026 speech, what it means for renters, flats and bills, with quotes and the regulatory context the press coverage missed.
AnalysisEnergy prices keep climbing. As a London renter, I decided plug-in solar bundle kits from £499 are the most logical step to take back control of bills.
MethodologyHow sun position, peak sun hours and angle decide what a UK plug-in solar panel is actually worth, plain English, and how the calculator uses each input.
MethodologyMost UK solar calculators overestimate savings. How we model PVGIS satellite data, sun position and self-consumption to give honest plug-in solar figures.
