If you’ve been holding off on going solar, now might be the time to revisit that quote. According to EnergySage’s new Solar & Storage Marketplace Report, prices for both home solar and solar + storage reached record lows in the second half of 2024.
EnergySage, an online solar shopping marketplace (and Electrek affiliate) analyzed millions of quotes from installers across the US in its 20th semiannual report. The data covers January through December 2024 and offers a detailed look at what homeowners pay for solar panels, batteries, inverters, and more.
Home solar and battery storage price quotes hit record lows
The median price for solar-only systems dropped to $2.65 per watt in the second half of 2024, down from $2.80 per watt earlier in the year. That’s the lowest price EnergySage has recorded.
Battery-backed systems saw an even bigger price drop: home solar + storage quotes fell from $2.59 per watt in H1 2024 to $2.40 per watt in H2 2024. Tesla’s Powerwall 3 is playing a big role in the storage price drop. The new version includes an integrated inverter, which shifts some of the cost from the solar quote (measured in $/W) to the storage quote (measured in $/kWh).
These falling prices were driven by a mix of factors. Equipment costs have dropped – Wood Mackenzie reports that residential solar panel prices were down 30% year-over-year. High interest rates and stable electricity prices have softened demand, pushing installers to offer more competitive pricing. And in California, changes to the state’s Net Billing Tariff have also pressured installers to drop prices.
“Heading into 2025, solar and battery prices had never been lower on the EnergySage Marketplace, and for homeowners, that means more affordable and accessible clean energy solutions,” said Emily Walker, director of content and insights at EnergySage. “This creates a compelling record-low benchmark to measure against as we begin to see the effects of shifting policies and tariffs take hold this year.”
Say hello to high-wattage solar panels
Home solar panels are getting more powerful, faster. In H2 2023, 81% of quotes included panels rated under 400 watts. By H2 2024, that number had dropped to just 14%. The shift is thanks to advances in panel efficiency and design: Either the panels themselves are getting bigger, or they’re packing more power into the same space.
High-wattage panels can reduce the number of panels needed per home, saving space and installation time. But there’s a wild card in 2025: tariffs. Bloomberg reported in April that the US had a stockpile of 40-50 gigawatts of solar panels at the end of 2024, which may buffer the US solar industry from big price hikes. However, that could slow down innovation and complicate the supply chain.
“As panel technologies improve, more homeowners are being offered higher-output systems – meaning fewer panels, more power, and a better return on investment,” said Walker. “We’re closely watching how inventory strategies and upcoming tariffs may shape this trend.”
