Analyze a residential solar proposal for clarity and completeness before a homeowner signs. Accepts the pricing, financing, system/battery, and installer details from a quote and returns a structured second-opinion review: a Quote Clarity Score (0-100) across four dimensions (Price Transparency /25, Financing & Contract Clarity /30, System & Battery Evidence /25, Installer & Protection Readiness /20), an overall rating, plain-language red flags, missing information, specific questions to ask the installer, and a recommended next step. Illustrative educational decision support only — not legal, tax, financial, or engineering advice, does not guarantee savings or system performance, does not endorse any installer, and takes no consequential action.
