Planning estimate — confirm scope, prices and operating assumptions with qualified installers and fuel suppliers. Tools prepare questions and scenarios; they do not approve an electrical or fuel-system design.

Equal scope before lower price
A normalization subtotal includes only the incremental amounts you supply. Unpriced exclusions, unresolved allowances and unknown scope remain open questions. Even a complete price table cannot validate the design, contractor qualifications, exclusions or warranty enforceability. It does not rank one installer as “best.”
Ask each installer to confirm the same fuel, backed-up loads, generator and transfer equipment, site work, permits, commissioning and service responsibilities. Save the dated offer and written clarifications. Use the full quote checklist.
