Credit score: Photo voltaic United Neighbors
After a yr of contraction, residential photo voltaic and storage costs each reached new all-time lows whilst panels have continued to extend in energy output, in keeping with the 20th EnergySage Intel: Solar & Storage Marketplace Report launched at this time.
This semiannual report analyzes tens of millions of transaction-level knowledge factors from householders buying on EnergySage.com from January by means of December 2024 for photo voltaic panels, inverters, batteries and extra from photo voltaic firms in all 50 states and Washington, D.C.
EnergySage’s report captures the traits shaping client conduct, installer choices and gear preferences, whereas spotlighting early indicators of how tariffs, rates of interest and Tesla model backlash might affect the market within the months forward.
Beneath are three key insights from the newest report, which may be downloaded free of charge at energysage.com/data.
Residential photo voltaic and storage costs each attain new all-time lows
Photo voltaic costs dropped for the third consecutive six-month interval, hitting $2.50 per watt, the bottom median quoted worth since EnergySage started monitoring knowledge in 2014. Quoted storage costs additionally fell, setting a brand new document low of $999 per kilowatt-hour saved.
“Heading into 2025, photo voltaic and battery costs had by no means been decrease on the EnergySage Market, and for householders, which means extra inexpensive and accessible clear vitality options,” stated Emily Walker, director of content material and insights at EnergySage. “This creates a compelling record-low benchmark to measure towards as we start to see the results of shifting insurance policies and tariffs take maintain this yr.”
Tesla’s Powerwall 3 disrupts the storage — and photo voltaic — market
Tesla grew to become the most-quoted battery model in H2 2024, occupying 63% of market share nationwide. As a result of the Powerwall 3 contains an built-in inverter, Tesla additionally grew to become the second-most quoted inverter model. With batteries more and more being added to photo voltaic programs — the nationwide battery attachment price jumped to 45% in H2 2024, an all-time excessive—Tesla’s progress was a key driver of the low storage and photo voltaic costs seen on EnergySage.
“Tesla’s rising dominance in each storage and inverter quotes displays the market’s urge for food for built-in, all-in-one options,” stated Charlie Hadlow, President and COO of EnergySage. “However as issues round availability and model sentiment floor, we’re watching carefully to see whether or not this momentum holds or if client backlash will start to shift installer and house owner preferences.”
Rated photo voltaic panel output continues to climb
Photo voltaic panels have continued to extend in energy output resulting from bigger sizes and better efficiencies. In H2 2024, 33% of quotes included photo voltaic panels with rated outputs above 450 W, up from simply 1% in H2 2023. EnergySage is monitoring tariff-related photo voltaic panel stockpiling to see if it hinders U.S. photo voltaic expertise progress in 2025.
“As panel applied sciences enhance, extra householders are being provided higher-output programs — that means fewer panels, extra energy, and a greater return on funding,” Walker stated. “We’re carefully watching how stock methods and upcoming tariffs might form this development.”
For a decade, the Photo voltaic & Storage Market Report has offered an unparalleled look into the traits for pricing, gear, and client preferences shaping at this time’s U.S. residential photo voltaic, vitality storage and residential electrification trade.
“The info on this report tells a broader story concerning the trade’s evolution,” Hadlow stated. “From the rise in storage adoption to the shift towards higher-efficiency gear and decrease prices, we’re seeing householders take higher management over their vitality selections. EnergySage is right here to assist them energy their method.”
