Are residential solar prices falling?
Residential solar prices are falling lower than ever before, said marketplace operator EnergySage in its biannual solar and storage marketplace report. The median quoted price on its platform reached $2.50 per watt in the second half of 2024, falling 6.4% from the first half of 2024.
How much did solar panels cost in 2024?
Analyzing millions of transaction-level data points from homeowners on EnergySage, it highlighted a clear milestone for solar panels: The average price had dropped 30% year-over-year in 2024. According to the report, the median quoted price of solar decreased for the third year in a row, hitting its lowest in recorded data at $2.50 per watt.
How much does solar cost?
According to the report, the median quoted price of solar decreased for the third year in a row, hitting its lowest in recorded data at $2.50 per watt. "For a system at the median size of 11.5 kilowatts, that amounts to $28,750 before incentives," the report said. With incentives, you can save as much as 75% of installation costs.
Why did solar panel prices drop 30% in 2024?
Wood Mackenzie reported solar panel prices dropped 30% year-over-year in 2024. Prices may have also lowered due to softened demand, said EnergySage. Residential solar installations declined 31% in 2024. This is “driven by high interest rates, relatively stable residential electricity prices, and California's Net Billing Tariff,” said the report.
