San Marino's Population, Property Values, and Electricity Costs
San Marino has an estimated 2026 population of approximately 11,861 residents.
As of June 2026, Zillow reported an average San Marino home value of approximately $2.84 million, representing a 7% increase over the previous year. With property values at this level, solar, roofing, battery, and electrical work should be evaluated carefully with attention to system design, workmanship, equipment quality, and contractor accountability.
EnergySage reports that San Marino residents requesting solar quotes through its marketplace spend approximately $386 per month and 35 cents per kilowatt-hour on electricity. EnergySage notes that households shopping for solar through its marketplace may consume more electricity than the typical household, so these figures should be treated as a local market reference.
For additional local solar information, property owners can also review the Solar Energy Local San Marino resource page. Historical data on the site reports an average annual solar-radiation value of approximately 6.17 kWh per square meter per day, with the strongest historical solar conditions occurring during the summer months.
Are Solar Panels Worth It in San Marino?
Solar may be worthwhile when the system is properly designed, competitively priced, professionally installed, and aligned with the homeowner’s electricity usage and long-term property goals.
EnergySage currently estimates an average 4.3-year cash-purchase payback period among San Marino users of its marketplace. Actual results vary based on electricity consumption, system cost, financing, roof conditions, equipment, utility rates, and other property-specific factors.
Online estimates can provide a helpful starting point, but an accurate solar evaluation requires an experienced consultant to review the property’s utility usage, roof layout, obstructions, shading, electrical requirements, and proposed contract.
