Socket Sun is an independent website. It is meant to be paid through affiliate links: when you click a link to a seller (for example EcoFlow, BLUETTI, Jackery, Anker SOLIX or Zendure) and buy, the seller may pay us a commission, at no extra cost to you. We say so at the top of every page with such links, in line with the CAP Code rules on marketing communications (ASA) and the CMA's guidance on online endorsements.
As of 14 November 2026, no affiliate programme has accepted Socket Sun. Every link to a seller is a plain link that earns us nothing. When a programme accepts the site, its links will carry a tracking code and this page will name it.
How we work
- We have not bought, installed or tested any kit. We compare what sellers publish, and we calculate generation from public data (EU PVGIS) and savings from the Ofgem price cap.
- Every figure has its source and the date we read it. When a figure is not published, we say "not published". Our own arithmetic is marked [calc].
- Our picks follow written rules (the cheapest kit that meets the condition). No seller pays to be listed or ranked.
- No star ratings, no scores, no customer reviews written or imported by us.
Prices
Prices include VAT and are those shown on the day we checked (14 November 2026, during Black Friday sales). A struck-through price appears only when the seller shows one. Check the seller before you buy. Method in detail: how we compare.
Not advice
Socket Sun summarises official texts and does the maths. It does not give electrical, legal or financial advice: follow the maker's instructions, the official guidance and, where they say so, a qualified electrician.
