Compare assumptions, not just monthly payment
Strong quotes explain annual electricity use, system size, production assumptions, module and inverter choices, shade assumptions, utility rates, ownership model, financing costs, and whether storage is included.
Check ownership and transfer details
Cash, loans, leases, and PPAs create different responsibilities. Homeowners should understand maintenance, monitoring, tax-benefit ownership, escalators, buyout terms, and home-sale transfer requirements before signing.
Ask for the site-specific review
Satellite layouts are useful early, but decision-ready proposals need a site review that considers roof condition, shade, attic or electrical access, main panel capacity, HOA rules, permits, and utility interconnection.
