The Revival of Batteries in Home Solar Systems

Explore the evolution of residential solar energy storage, from its early days to the resurgence of battery systems for grid independence.

In the realm of home solar power, history is repeating itself. Initially, when residential solar gained popularity in the late 20th century, battery storage was a staple in nearly all setups. However, the early 2000s saw a shift away from batteries due to government incentives like net metering and tax credits, which favored grid-tied systems without the need for battery backup.


But as we navigate away from net metering and more homeowners aim for independence from the grid, the demand for durable, environmentally friendly, and economically beneficial batteries is making a strong comeback. John Cromer, the Director of Product at Fortress Power, notes this trend as a natural cycle. The industry has moved from widespread battery use to minimal, and now, it's swinging back to widespread adoption.


The Beginnings of Home Energy Storage


Originally, homeowners turned to solar and batteries mainly out of necessity—either due to their remote locations or the cost-prohibitive nature of grid connection. Back then, bulky lead acid batteries were the norm, allowing off-grid living but at the cost of frequent replacements due to their intolerance to deep discharges.

Despite the obvious need for better solutions, policy shifts temporarily sidelined the battery storage discussion.


The Shift with Net Metering


The introduction of the solar investment tax credit (ITC) and the concept of net metering in the mid-2000s significantly impacted the solar landscape. The solar ITC catalyzed industry growth, while net metering allowed homeowners to sell excess power back to the grid, effectively reducing or eliminating their electricity bills. This model, though beneficial for reducing upfront costs and encouraging solar adoption, downplayed the role of batteries.


Today's Changing Landscape


Fast forward to the present, the tide is turning. The diminishing presence of net metering, coupled with technological advancements and shifting priorities, is reigniting interest in battery storage. Cromer highlights the evolving policies, such as expanded tax credits for batteries and time-of-use rates, which present new economic incentives and support for grid independence without the contention surrounding net metering.


The Need for Solar Batteries Now


As the reliability of the grid comes into question, with incidents like the rolling blackouts in California, the value of having a battery backup becomes clear. Not only do batteries offer protection during outages, but they also address the challenges posed by aging infrastructure and the increasing demand on the grid. Moreover, with strict regulations limiting the use of generators in places like California, batteries offer a viable alternative, aligning with time-of-use rates to enhance economic benefits.


Cromer suggests a shift in industry focus towards optimizing battery storage rather than just maximizing solar panel output. This approach not only benefits homeowners by providing more reliable and efficient energy solutions but also opens new markets for installers. The future of solar, it seems, is incomplete without the inclusion of battery storage.


This evolving narrative marks an exciting chapter in the journey of residential solar energy, highlighting the cyclical nature of technology and policy, and underscoring the enduring value of battery storage in achieving energy independence and sustainability.
