Path-Q Solar

What should a solar quote include so I can compare it fairly with another quote?

Answer

A comparable quote should clearly state system size and expected production, equipment models, layout, included structural and electrical work, permits and interconnection, monitoring, warranties, price and payment terms, schedule, exclusions, and who owns or receives any associated benefits. Compare total scope, not just price or panel count.

Key points

  • Require model numbers or sufficiently specific equipment descriptions.
  • Separate base work from allowances, optional items, and potential upgrades.
  • Confirm whether roof repairs, service upgrades, batteries, taxes, permits, and utility fees are included.
  • Ask for production assumptions and the method used to calculate them.

What it depends on

  • Project design and site conditions
  • Equipment and warranty choices
  • Permit, interconnection, and upgrade scope
  • Payment, ownership, and financing structure

Risks and trade-offs

  • An incomplete quote can appear cheaper while shifting costs into change orders.
  • Projected production and savings are not the same as guaranteed performance.
  • Different ownership or financing structures may make headline prices misleading.

Information you may need

  • Itemized scope and exclusions
  • Equipment model numbers and warranties
  • Production model and assumptions
  • Payment, cancellation, escalation, and change-order terms
