The solar energy storage market has shifted from an optional add-on to an increasingly essential component of residential and commercial solar installations. Industry professionals at recent trade events note that conversations about solar now almost invariably include discussion of battery storage, particularly in markets where policy changes and grid reliability concerns have made standalone solar less attractive.

At Aurora Solar's Empower conference, Rachel Liddell, Director of Product Management at Aurora, and Chris Collins, Founder and CEO of Ohm Analytics, presented a detailed analysis of the forces driving battery storage adoption. Their session focused on identifying the primary growth drivers in the storage market and highlighting emerging opportunities for solar installers that remain largely unclaimed.

The broader industry context for this shift is well established. Residential battery storage deployment in the United States has accelerated in recent years, propelled by several converging trends. Changes to net metering policies in major solar states have reduced the value of exporting excess solar generation to the grid, making self-consumption via batteries more economically compelling. California's transition from full retail net metering to net billing under NEM 3.0, which took effect in 2023, sharply reduced export compensation rates and is frequently cited as a pivotal example. Time-of-use electricity rate structures, which create wider gaps between peak and off-peak pricing, have further improved the financial case for storage. Grid reliability concerns, including the growing frequency of weather-driven power outages in states such as California and Texas, have also elevated consumer interest in backup power capabilities. The expansion of the federal Residential Clean Energy Credit under the Inflation Reduction Act, which extended a 30% tax credit to standalone battery storage systems of at least 3 kWh, has further reduced the upfront cost barrier for residential customers.

The expansion of virtual power plant (VPP) programs represents another significant demand driver. VPPs aggregate distributed battery systems across many homes and businesses, allowing grid operators to draw on stored energy during periods of high demand. Homeowners who participate in these programs can earn payments or bill credits in exchange for making a portion of their battery capacity available. Several utilities and grid operators across the United States have launched or expanded VPP initiatives, creating a new revenue stream that improves the return-on-investment calculus for residential batteries.

Retrofitting existing solar installations with battery storage is emerging as a substantial and largely untapped market segment. Millions of residential solar systems were installed in the years before battery storage was widely available at competitive prices. Many of those homeowners are now returning to add storage, creating a broad addressable opportunity for installers who can efficiently serve the retrofit market.

Aurora Solar is a solar design and sales software platform widely used by residential and commercial installers. Ohm Analytics is a market research firm specializing in the distributed energy resources sector, including solar, storage, and electrification trends.
