Solar panels in the UK, compared

A UK-specific comparison of 400W, 405W and 420W panels available to plug-in solar buyers in 2026. Currently in development.

This page is coming soon

I am gathering verified spec sheets, real prices and ENA G98-context for each panel before publishing. Solar panel claims are heavily marketed; I want to ship a comparison I can stand behind, not a regurgitated brochure.

Expected publication: June 2026.

What this page will cover

  • The four panel categories UK plug-in buyers actually meet: 400W bifacial, 405-420W monofacial, half-cell vs full-cell, and 800W kit-paired sets.
  • Spec comparison: Wp at STC, NOCT performance, temperature coefficient, dimensions, weight, warranty.
  • Real-world UK output: PVGIS-modelled annual yield per panel for the six largest UK cities, paired with the same microinverter for fair comparison.
  • Manufacturer shortlist: JA Solar, Trina, LONGi, Canadian Solar, JinkoSolar, Renogy. Channel availability and warranty support inside the UK.
  • Buyer matrix: renter / homeowner, balcony / garden / pitched roof, summer-only vs all-year.
  • Prices: retail per panel and per Wp, updated against Amazon UK and specialist suppliers.

In the meantime

For UK kit-level comparisons that already exist, see the Products page (EcoFlow STREAM 800W and Stream Pro). For the panel's pairing partner, the microinverter comparison is live now.
