Homeowners are shifting from exporting excess solar power to the grid toward storing it in batteries due to changing net metering rules and climbing electricity prices. This trend favors systems that combine solar panels with batteries and electric vehicles for better energy management. Experts highlight the potential for integrated whole-home electrification solutions.
Net metering, which allows selling excess electricity from rooftop solar panels back to the grid, has driven the adoption of home solar for over a decade. However, evolving regulations, such as California's Net Energy Metering 3.0 (NEM3.0), have significantly lowered the financial benefits of exporting power. As a result, many homeowners now prefer to retain surplus solar-generated electricity for personal use, often by storing it in batteries alongside off-peak power purchases.
Batteries enable energy arbitrage, charging during low-cost periods and discharging during high-demand times when rates are elevated. A commenter noted: "Another reason is that batteries function as energy arbitrage devices. They can charge when electricity is cheap and discharge when it is expensive. Even in the winter when solar isn’t doing much. This reduces the need for expensive peaker plants, and increases utilization of cheaper power sources."
This flexibility addresses growing grid demands and higher bills, prompting a market shift from standalone solar to combined solar-plus-battery setups, and increasingly including electric vehicles (EVs). Systems integrating smart meters, panels, solar, batteries, and EVs treat the vehicle as part of a home power plant, optimizing storage, usage, and export.
Tracy Price, founder and retired CEO of EV charging installers Qmerit, stated: “America has arrived at an inflection point in which the technical, policy, and financial pieces are finally in place for whole-home electrification.” He added: “What’s needed now is a way to integrate those technologies into a simple home energy system that homeowners can actually use.”
Platforms like Tesla's Powerwall with Cybertruck, GM Energy’s V2H Bundle, and ecosystems from Rivian and Nissan coordinate these elements into cohesive solutions, functioning like miniature grids.
