What these tools do not hide
Every calculator exposes its assumptions. Replace planning defaults with figures from your utility bill, equipment label, installer quote or manufacturer manual. The tools do not collect contact details and do not send results to installers.
Use estimates to screen decisions, not replace a site assessment. Roof shading, utility tariffs, motor startup demand, wiring and equipment compatibility still need project-specific checks.
