Editorial Policy

Focus Solar publishes independent educational material for people researching solar systems. Our aim is to make technical and financial decisions easier to inspect—not to replace site-specific engineering, electrical design, legal advice, or financial advice.

Our editorial principles

• Decision usefulness: each guide should help a reader make or prepare for a real decision.
• Visible assumptions: calculations and comparisons should state the inputs that materially affect the answer.
• Source traceability: factual claims should link to primary or well-established technical sources where practical.
• Clear limits: regional rules, product specifications, prices, incentives, and tariffs can change.
• No invented authority: we do not claim credentials, partnerships, user counts, or review arrangements that do not exist.

Review and updates

Content is reviewed through the Focus Solar editorial process for clarity, internal consistency, calculation logic, source quality, and technical plausibility. This is an editorial check, not certification by a named engineer unless a page explicitly and verifiably says so.

We update content when material source data, technology, market conditions, or policy context changes. A displayed update date refers to the page content, not to every external source it links.

Independence and corrections

Focus Solar does not sell installer referrals. If commercial relationships are introduced, they will be disclosed where relevant. Readers can report an error through Contact & Feedback. See our Corrections Policy.
