Plug Solar Hub Changelog and Corrections

1. Recent changes

• 27 April 2026 AddedGermany solar-day infographic

  Static SVG infographic added to /germany-most-popular-balcony-solar-kits, showing solar's share of Germany's electricity grid through a typical sunny summer day. Source-attributed to Fraunhofer ISE Energy-Charts (CC BY 4.0), cross-referenced with Bundesnetzagentur SMARD.

• 27 April 2026 AddedSite changelog page

  This page. Added at /changelog to act as the canonical home for substantive changes and reader-flagged corrections. Referenced from the Complete UK Guide and the BSI 2026 Tracker.

• 27 April 2026 AddedBS 7671 and Plug-In Solar in the UK

  New regulatory page shipped at /bs7671-plug-in-solar-uk, structured around the eight wiring branches that decide compliance for an 800W plug-in solar kit: protection from electric shock, connection of generating equipment, overcurrent and backfeed risk, isolation and switching, external influences, labelling and identification, inspection and testing, and G98 / G99 DNO coordination.

• 27 April 2026 ChangedSitewide nav: Guide dropdown

  BSI 2026 Tracker and BS 7671 & Plug-In Solar links added to the Guide dropdown across all 27 user-facing pages. Closes the 24-hour analytics gap where readers were hitting the new pages without a nav route to them.

• 25 April 2026 AddedBSI 2026 Plug-In Solar Tracker

  Standards-status tracker shipped at /bsi-2026-tracker, covering BS 1363-1:2023, BS 7671:2018+A4:2026, the BSI plug-in solar product standard expected July 2026, and ENA EREC G98. Each claim dated and linked to the primary source.

• 25 April 2026 DataOpen UK plug-in solar yield dataset

  Free CSV published at /data/uk-plug-in-solar-yield-by-city.csv (CC BY 4.0, 29 reference cities, PVGIS-anchored), with full methodology at /data/uk-plug-in-solar-yield-methodology. Modelled at the Ofgem Q2 2026 default tariff cap (27.7 p/kWh) and an indicative 5 p/kWh SEG rate.

• 22 April 2026 ChangedCalculator: UK postcode integration

  /calculator now accepts an optional UK postcode. Postcodes.io resolves it to coordinates, and PVGIS v5.3 returns satellite irradiance for those exact coordinates rather than a national average. Falls back gracefully to city-level estimate on invalid postcode, network error or timeout. Cross-page mentions added to /guide, /blog-plug-in-solar-calculator-uk, /blog-energy-security-plug-in-solar, /plug-in-solar-with-battery-worth-it.

• April 2026 FixPlug-in solar legality copy across 17+ pages

  After expert email feedback, the site was audited for any copy that overclaimed the legality of plug-in via a 13A socket. Phrasing such as "BS 7671 Amendment 4 makes plug-in solar legal" and "DIY-legal in July 2026" was removed across 17+ pages. Replacement copy describes what each standard does and does not do, and identifies the compliant route as a CPS-certified electrician with a hardwired connection. The factual-accuracy rule was added to project conventions to prevent recurrence.

• April 2026 ChangedEducation-first pivot

  Homepage hero, products page hero, and Open Graph metadata repositioned to address first-adopter readers (renters, flat-dwellers, researchers) rather than near-term buyers. Voice unified to first-person founder. Site-wide style guide added.

• April 2026 AddedBuyer's checklist lead magnet

  Free buyer's checklist landing page shipped at /buyer-checklist, with thank-you page and Mailchimp double-opt-in. PDF covers BSI certification, microinverter specs, mounting compatibility, G98 compliance, UK plug cable, insurance notification, panel efficiency, weight limits, shading and smart-tariff compatibility.

• April 2026 AddedSix UK city guide pages

  Local landing pages shipped: London, Manchester, Bristol, Edinburgh, Birmingham, Leeds. Each carries city-level PVGIS yield, Ofgem-rate-anchored payback, and renter-specific guidance.

• April 2026 AddedThree feature pages

  Shipped /germany-most-popular-balcony-solar-kits, /best-solar-kits-for-renters-uk, /plug-in-solar-with-battery-worth-it, and /best-plug-in-solar-kits-under-500.

2. Corrections logged after reader feedback

This is where corrections appear when a reader, electrician, journalist or solicitor flags an error. Each entry will record the date, the original claim, the corrected claim, and every page that was updated as a result.

3. Corrections policy

Reputation is the single biggest asset of an independent UK solar site. The corrections policy is short and binding:

1. Email me directly. [email protected]. Quote the page URL and the claim you think is wrong, and (where possible) cite the underlying standard, regulation or primary source.
2. Seven-day fix. I aim to apply substantive corrections within seven calendar days. Urgent legality or safety claims are prioritised.
3. Site-wide sweep. When a flagged claim appears on more than one page, every affected page is corrected in the same pass. The sweep is logged here under "Corrections logged after reader feedback".
4. No silent edits. Substantive corrections are recorded on this page with the date and a short note. Routine typo fixes and styling tweaks are not.
5. Source-led. Where I cite a British Standard, an IET regulation, an ENA recommendation or a UK government document, I prefer the more conservative reading and link the primary source. The aim is for any claim on the site to be verifiable in under a minute by following the cited link.
