A useful answer should show its working.
Who is responsible
Solar Sizer is an independent publishing project operated by Rhys. An article credited to Solar Sizer does not imply a team of credentialed specialists. Questions and corrections: [email protected].
Sources and their limits
We prefer government or original legal records for rules and the exact regional manufacturer documentation for equipment. Consumer guidance and public research models provide context. A source link does not imply that its publisher endorses every example or conclusion on this site.
Four kinds of statement
- Sourced information: a dated statement supported by a linked publication.
- Model output: a calculation under the published assumptions.
- Worked example: explicitly assumed values used to explain a decision.
- Hands-on experience: only described that way when actual observations, period and limitations are documented.
The blog’s worked examples are not product tests or measurements of a customer’s home. General solar and residential photographs illustrate the subject; they do not document an approved installation.
AI assistance
AI can assist with structure and drafting. It does not create first-hand product experience or professional credentials. Sources, assumptions and unanswered questions remain explicit. We do not claim an independent technical or native-language review unless it has actually taken place.
Commercial independence
Compensation must not change the calculation formulas, capacity comparison or no-battery option. Commercial relationships will be visible. Read the advertising and affiliate policy.
Corrections and updates
Send the page, the disputed statement and, if possible, a primary source. Material revisions receive a visible update date. Changing a date is not a substitute for reviewing the content.
