Methodology
How SolarGabay formulas, assumptions, uncertainty, review dates, and source records work.
Our calculations are versioned, reviewed, and reproducible. Each result carries a formula version so a future calculation can be reproduced against the same method.
Assumptions include location scope, effective date, review date, source type, confidence, and formula compatibility. Results use ranges where site conditions, prices, weather, or behavior materially affect the answer.
Primary public pages focus on the strongest solar and electricity calculators and guides. Supporting routes remain usable while their data, examples, sources, and review notes continue to improve.
Calculators are planning tools. Solar results are not engineering designs, certifications, guaranteed savings, or binding quotations.
