EnergySage marketplace medians for Southern California have been in the mid-$2s per watt in 2026 for a standard rooftop solar-only install before the 30% ITC. Tile roofs, main-panel upgrades, and battery storage push the number higher. Quotes that land well above $3.20/W for a standard composition-shingle roof deserve a line-item explanation.
