US small-scale solar hits record 1.9 GW in Q4 2025

<p class="p1"><span class="s1">Distributed solar accounted for 15% of all new US power capacity in 2025, as residential and community projects reached record installation levels.</span></p><p><strong>From <a href="https://pv-magazine-usa.com/2026/03/31/u-s-small-scale-solar-hit-record-1-9-gw-in-q4-2025/" rel="noopener" target="_blank">pv magazine USA</a></strong></p>
<p><span>The US solar market reached a new milestone in the final quarter of 2025 as distributed capacity surged to a record 1.9 GW of new installations. Data from the Institute for Local Self-Reliance (ILSR) shows this quarterly peak capped a year where solar generation accounted for 78% of the 46 GW of new power capacity added to the national grid.</span></p>
<p><span>While utility-scale projects dominated installed capacity at 63%, the 15% contributed by residential and community solar projects indicates strength in the distributed energy segment. ILSR and the Energy Information Administration define distributed or “small solar” as less than 1 MW in nameplate capacity, and generally connected to the grid behind the meter.</span></p>

<p><span>Market analysts suggest the fourth-quarter surge was driven in part by a rush to secure the 25D residential energy efficient property tax credit. The incentive, which provided a 30% credit for solar electric property, began its scheduled phase-down at the end of the year, prompting homeowners to finalize interconnections before the deadline.</span></p>
<p><span>The cumulative impact of these behind-the-meter assets is building a case for a decentralized grid by bypassing the multi-billion dollar bottlenecks of traditional transmission expansion. This growth is further bolstered by the 15 GW of new energy storage deployed in 2025. Approximately 14% of that storage capacity was installed at the distributed level to provide essential grid balancing.</span></p>
<p><span>Despite persistent regulatory hurdles, the closing months of 2025 demonstrated that small-scale solar remains a driver of US energy resilience. The technical and economic data suggests the decentralized model is challenging the century-old centralized utility paradigm.</span></p>
<p><span>Distributed resources continue to offer unique advantages to the grid beyond simple capacity additions. These benefits range from reduced land-use requirements and lower transmission losses to increased local job creation and price predictability for consumers.</span></p>
