Residential Solar Prices Plummet as Tesla Leads Battery Market Revolution

Major Shifts in the Solar Market: Insights from EnergySage's 2024 Report

The latest report by EnergySage, a leading platform for comparison shopping in the clean energy sector, reveals transformative changes in the residential solar and storage marketplace. After a period of contraction, prices for both solar and battery storage solutions have reached unprecedented lows. This shift is significant not just for consumers but also for the overall energy landscape as we move into 2025.

Record Low Prices and Consumer Benefits

According to the 20th edition of the EnergySage Solar & Storage Marketplace Report, residential solar prices have decreased for three consecutive six-month periods. The median solar price now stands at $2.50 per watt, marking the lowest since EnergySage commenced tracking these data points in 2014. Similarly, the cost of battery storage has also seen a drastic reduction, with new record lows at $999 per kilowatt-hour stored.

Emily Walker, Director of Content and Insights at EnergySage, emphasized the implications of these developments: “Heading into 2025, solar and battery prices had never been lower on the EnergySage Marketplace, meaning homeowners now have access to more affordable clean energy options.” This affordability is crucial, especially as various market factors—like tariffs and interest rates—play an influential role in shaping future consumer decisions.

Tesla's Dominance in the Battery Market

Another critical insight from the report highlights Tesla's emerging dominance in the battery storage space. The Powerwall 3, Tesla's latest offering, captured an impressive 63% of the marketplace share for battery brands in the latter half of 2024. This dual-role inverter system has positioned Tesla not only as the top battery supplier but also as the second-most quoted inverter brand. With the increasing trend of integrating battery storage into solar installations, the national attachment rate jumped to 45% in the same period—the highest ever recorded.

Charlie Hadlow, President and COO of EnergySage, remarked on Tesla's market influence: “The popularity of integrated, all-in-one solutions reflects the growing demand among consumers looking for efficiency.” However, he cautioned that ongoing brand sentiment and availability could shift consumer preferences in the months to come, indicating potential volatility within the marketplace.

Advancements in Solar Technology

The performance of solar panels continues to evolve as manufacturers push for higher efficiency and larger sizes. In fact, the report shows that 33% of quotes from the latter half of 2024 included solar panels with rated outputs exceeding 450 watts, a significant growth from just 1% a year earlier. This reflects a broader trend of decreasing installation sizes while maximizing energy output, enabling homeowners to achieve a better return on investment.

EnergySage analysts are keenly observing how tariff-related developments may affect solar technology advancements and stockpiling strategies that could come into play in 2025.
