What feeds the calculators, and how current it is.
Representative daily peak-sun-hour values by state, with city-level overrides where coastal/inland or valley/mountain differences are large. Directionally based on NREL solar resource data. For a precise figure, a site-specific tool like NREL PVWatts is the reference.
Representative residential $/kWh by state, in the spirit of EIA state electricity data. Your utility's current tariff is authoritative.
Typical installed price-per-watt ranges by state, reflecting recent U.S. residential market pricing. Actual quotes vary widely by installer and equipment.
Federal tax-credit logic follows Section 25D (30% through 2025, 0% for 2026+ residential). State/utility incentives are representative values for roughly 22 states; verify against your state energy office, your utility and the DSIRE database.
Company name, headquarters, founding year, website and service description come from company websites and public records. Ratings, reviews, certifications and license numbers are shown as not yet verified until checked.
These are planning inputs for an MVP, not a live data feed. We're working toward site-specific sun and rate data and verified incentive data. Report anything that looks off via contact.
