Residential Solar Prices Dropped and Tesla Dominated Battery Market, according to EnergySage's 2024 Solar & Storage Marketplace Report

20th edition of EnergySage report captures consumer trends from 2024, offers insight into 2025
BOSTON, April 29, 2025 /PRNewswire/ -- After a year of contraction, residential solar and storage prices both reached new all-time lows even as panels have continued to increase in power output, according to the 20th EnergySage Intel: Solar & Storage Marketplace Report released today.
This semiannual report analyzes millions of transaction-level data points from homeowners shopping on EnergySage.com from January through December 2024 for solar panels, inverters, batteries, and more from solar companies in all 50 states and Washington, D.C.
EnergySage's report captures the trends shaping consumer behavior, installer offerings, and equipment preferences, while spotlighting early indicators of how tariffs, interest rates, and Tesla brand backlash may influence the market in the months ahead.
Below are three key insights from the latest report, which can be downloaded for free at energysage.com/data.
Residential solar and storage prices both reach new all-time lowsSolar prices dropped for the third consecutive six-month period, hitting $2.50 per watt, the lowest median quoted price since EnergySage began tracking data in 2014. Quoted storage prices also fell, setting a new record low of $999 per kilowatt-hour stored.
"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."
Tesla's Powerwall 3 disrupts the storage—and solar—marketTesla became the most quoted battery brand in H2 2024, occupying 63% of Marketplace share nationwide. Because the Powerwall 3 includes an integrated inverter, Tesla also became the second-most quoted inverter brand. With batteries increasingly being added to solar systems—the national battery attachment rate jumped to 45% in H2 2024, an all-time high—Tesla's growth was a key driver of the low storage and solar prices seen on EnergySage.
"Tesla's emerging dominance in both storage and inverter quotes reflects the market's appetite for integrated, all-in-one solutions," said Charlie Hadlow, President and COO of EnergySage. "But as concerns around availability and brand sentiment surface, we're watching closely to see whether this momentum holds or if consumer backlash will begin to shift installer and homeowner preferences."
Rated solar panel output continues to climbSolar panels have continued to increase in power output due to larger sizes and higher efficiencies. In H2 2024, 33% of quotes included solar panels with rated outputs above 450 watts, up from just 1% in H2 2023. We are tracking tariff-related solar panel stockpiling to see if it hinders U.S. solar technology growth in 2025.
"As panel technologies improve, more homeowners are being offered higher-output systems—meaning fewer panels, more power, and a better return on investment," said Emily Walker, Director of Content and Insights at EnergySage. "We're closely watching how inventory strategies and upcoming tariffs may shape this trend."
For a decade, the Solar & Storage Marketplace Report has provided an unparalleled look into the trends for pricing, equipment, and consumer preferences shaping today's U.S. residential solar, energy storage, and home electrification industry.
"The data in this report tells a broader story about the industry's evolution," said Charlie Hadlow, President and COO of EnergySage. "From the rise in storage adoption to the shift toward higher-efficiency equipment and lower costs, we're seeing homeowners take greater control over their energy choices. EnergySage is here to help them power their way."

Tesla's robotaxis launch in Texas with 10-vehicle trial run: See photos

Tesla's "fully autonomous" robotaxis made their debut in Austin, Texas this weekend. On Sunday, June 22, a small fleet of Tesla's taxis began offering rides to people in the state's buzzing capital, according to Reuters. It marks the first time Tesla's self-driving cars picked up paying riders. The launch was a "culmination of a decade of hard work," Tesla CEO Elon Musk wrote in a post on his social media platform X. "Super congratulations to the @Tesla_AI software & chip design teams on a successful @Robotaxi launch!!" Musk added. Tesla did the trial run with 10 vehicles in the a neighborhood called South Congress, reported Reuters. While no one was in the driver's seat, a front-seat rider acted as a "safety monitor" during the trial. It is unclear how much control safety monitors had over the car. Some people, however, gathered to show their disapproval of the new self-driving taxis. Photos captured protesters gathered on Saturday with signs that stated, "No Robotaxi in Austin." Proceed with caution: Texas enacts robotaxi rules on the eve of Tesla's Austin rollout See photos from the launch.

The updated target implies a potential upside of about 9% from current levels. Warning! GuruFocus has detected 3 Warning Signs with NIO. Goldman Sachs analyst Tina Hou noted that Nio's efforts to reduce operating expenses by 20%25%including project cancellations, staff reductions, and streamlined operationscould support margin improvement of 4%10% over the next three years. Nio has faced challenges, including widening losses, a 21% year-to-date share price drop, and heightened competition from Tesla (TSLA, Financials) and BYD. Despite the upgrade, Goldman Sachs remains cautious. It cited weak demand, a high debt load, and reduced delivery expectations as ongoing risks. Nio's cash and investments declined from $5.7 billion to $3.6 billion in Q1 2025, underscoring balance sheet concerns. Wall Street maintains a Hold consensus on Nio stock, with two Buy, seven Hold, and one Sell ratings over the past three months. The average analyst price target is $4.58, suggesting a 33% upside.
