How this estimate works
SolarGabay uses pure, versioned TypeScript formula modules. The calculator normalizes inputs, rejects invalid values, and presents planning ranges instead of false precision.
Results are decision-support estimates. Confirm utility rates, supplier specifications, site conditions, and professional requirements before committing money. Review the methodology and source policy before treating any estimate as decision-ready.
