Path-Q Solar

How can I make solar quotes comparable when each installer inspected a different part of the property?

Answer

Create a common scope and data package, then ask each installer to price and model the same defined area, assumptions, equipment scope, and exclusions. If site coverage differs, separate the base comparison from optional areas rather than comparing totals directly.

Key points

  • Provide the same roof plans, photos, utility data, shading information, target capacity, and access constraints.
  • Require each quote to identify inspected areas, uninspected areas, assumptions, production model, equipment, site work, and exclusions.
  • Compare annual production, usable capacity, warranties, workmanship, schedule, and total scope in addition to price.

What it depends on

  • Which property areas are suitable and available
  • Completeness and accuracy of each site assessment
  • Roof, structural, electrical, and shading information
  • Whether quotes include batteries, roof work, upgrades, permits, and monitoring

Risks and trade-offs

  • A quote based on a larger or easier area may look cheaper or more productive without being equivalent.
  • Remote estimates may omit site conditions discovered during a detailed inspection.
  • Standardizing the scope improves comparison but may require follow-up inspections before final pricing.

Information you may need

  • Common site plan and marked inspection areas
  • Roof, electrical, utility, and energy-use information
  • Comparable production-model assumptions
  • Detailed equipment, scope, exclusions, warranties, and change-order terms

Your next step

What to do next

Issue a written request for revised, side-by-side proposals using one common scope and require each installer to disclose what was inspected and what remains uncertain.
