Use this hub to compare proposals with one consistent framework before signing. The goal is not to pick the fastest sales pitch, but to choose the scope that is clear, defensible, and aligned with your project goals.
Framework uses evergreen homeowner guidance patterns from U.S. DOE Energy Saver and AFDC-style decision planning: normalize scope, verify assumptions, and document responsibilities in writing.
Quote comparison workflow
Practical decision path: align proposals to the same scope, verify assumptions, check risk signals, and then shortlist providers.
Practical planning guide
Normalize scope before comparing price
• Match equipment class, labor scope, and change-order rules across every quote.
• Confirm whether permitting, inspections, commissioning, and utility paperwork are included.
• Compare timeline milestones using the same definitions for start, install, and handoff.
Questions to ask before signing
• Who is responsible for permit submission, corrections, and reinspection costs?
• What triggers a change order, and how are costs approved?
• Which post-install support channels are documented for troubleshooting and warranty claims?
Red flags during quote review
• Scope language that is too vague to verify equipment, circuit, or design assumptions.
• Pressure to sign before permit, electrical, or utility assumptions are clearly documented.
• Unclear division of responsibility between sales partner, installer, and subcontractors.
