Editorial policy

Last updated: 29 May 2026.

Authorship

All articles on this site are reviewed and approved by Sepehr, who is the sole author at this time. Sepehr is a UK homeowner researching solar, battery and EV charging for his own install — not a credentialed industry expert. Where claims require expertise (e.g. MCS-certification details, financial advice), we say so and link to authoritative sources rather than asserting expertise we don't have.

Scoring methodology

Every product is scored on per-category criteria with explicit weights. The weights sum to 1.0 per category and are published below. Scores are derived from published manufacturer specifications, not from lab testing or proprietary data.

EV chargers (weights sum to 1.0)

• Charge speed & performance — 25%
• Smart features & app — 20%
• Installation & compatibility — 20%
• Value for money — 20%
• Warranty & reliability — 15%

Solar panels (weights sum to 1.0)

• Panel efficiency — 25%
• Power output & degradation — 20%
• Warranty & longevity — 20%
• Value for money — 20%
• Install compatibility — 15%

Battery storage (weights sum to 1.0)

• Usable capacity — 25%
• Round-trip efficiency — 25%
• Inverter compatibility — 20%
• Warranty & cycle life — 20%
• Value for money — 10%

Use of AI in content

Long-form articles are drafted using AI (the Anthropic Claude API) and reviewed by Sepehr before publication. The review step is mandatory — no AI-drafted article goes live without Sepehr personally reading and approving it. AI does not assign product scores; those come exclusively from the formula above applied to manufacturer specs.

Affiliate relationships

See our affiliate disclosure page for the full statement. Short version: some links earn us commission, none of them affect scoring.

Updates and corrections

Products are reviewed when a major model revision is released. If we publish an error, we correct it inline and add a note at the top of the article noting when and what was corrected. If you spot an error, email me@sepehr.co.uk.
