Gain valuable market insights on the solar energy sector with SEIA’s comprehensive report on trends and the transformation towards a clean energy economy.

Introduction

The solar energy sector continues to be a pivotal player in the United States’ transition to a clean energy economy. According to the latest Solar Market Insight Report by the Solar Energy Industries Association (SEIA) and Wood Mackenzie Power & Renewables, the industry showcased significant developments in the first half of 2025. This report delves into the current market landscape, emerging trends, policy impacts, and future projections that shape the solar market.

Current Market Overview

In the second quarter of 2025, the U.S. solar industry installed 7.5 gigawatts (GW) of direct current (dc) capacity. This marks a 24% decline compared to Q2 2024 and a 28% decrease since Q1 2025. Despite these declines, solar energy accounted for 56% of all new electricity-generating capacity added to the U.S. grid in the first half of 2025, totaling 18 GW. When combined with energy storage solutions, solar and storage systems comprised 82% of the new capacity, highlighting their dominance in the market.

Manufacturing Capacity

The industry saw the addition of 4.3 GW in solar module manufacturing capacity during Q2 2025, bringing the total to 55.4 GW. However, there were no new upstream manufacturing facilities for polysilicon, wafer, or cell manufacturing, indicating a slow growth pace in this critical segment of the solar value chain.

Regional Installations

Texas led the installations with 3.8 GW dc, followed by California, Indiana, and Arizona.
The residential solar segment installed 1,064 MW dc, experiencing a 9% year-over-year decline and a 3% quarter-over-quarter decrease.
The commercial segment set a record with a 27% growth compared to Q2 2024, adding 585 MW dc.
Community solar installations dropped significantly, with a 52% year-over-year and 34% quarter-over-quarter decline.
Utility-scale solar faced a 28% year-over-year and 33% quarter-over-quarter decrease, primarily due to slowed deployment in Texas.

Industry Trends

Growth in Solar and Storage

The combination of solar installations and energy storage systems remains a cornerstone of new power capacity additions. The 82% share of solar and storage underscores their essential role in enhancing grid reliability and facilitating the integration of renewable energy sources.

Manufacturing Challenges

While module manufacturing capacity has increased, the lack of growth in upstream manufacturing poses challenges. Establishing new facilities for polysilicon, wafers, and cells is crucial for the industry’s sustainability and scalability.

Shifting Regional Dynamics

Texas continues to dominate the market, leveraging its vast land and favorable policies. California’s robust pipeline of Net Energy Metering (NEM) 2.0 installations contributes significantly to commercial solar growth. However, regions like Indiana and Arizona are also making notable strides, diversifying the geographic distribution of solar installations.

Segment Analysis

Residential Solar

The residential segment, despite its decline, remains a vital part of the solar market. High interest rates and policy uncertainties have hindered growth, emphasizing the need for stable incentives and financing options to support homeowners in adopting solar solutions.

Commercial Solar

Commercial solar has seen unprecedented growth, driven by California’s aggressive NEM 2.0 policies. These policies facilitate easier integration of solar projects, making commercial installations more attractive to businesses seeking sustainable energy solutions.

Community Solar

Community solar projects are experiencing a downturn, mainly due to saturation in major markets and a lack of new program developments. Expanding community solar initiatives into emerging markets could revitalize this segment.

Utility-Scale Solar

Utility-scale projects remain susceptible to policy shifts and economic fluctuations. The significant decline in Texas, a traditionally strong market, indicates the need for more resilient strategies to sustain large-scale solar deployments.

Policy Landscape

The passage of the One Big Beautiful Bill Act (OBBBA) has introduced substantial changes to the policy environment. Key impacts include:

Tax Credits: The solar industry will lose access to Section 48E and 45Y tax credits after 2027 and Section 25D tax credits for customer-owned residential solar after 2025.
Permitting Approvals: New federal guidelines require Interior Secretary Doug Burgum’s personal sign-off on various permitting approvals, potentially slowing project initiation.
Construction Definitions: Changes to the definition of “beginning of construction” by the U.S. Treasury may affect eligibility for federal tax credits.

These policy changes are poised to influence project timelines and financial planning, necessitating strategic adaptations by industry stakeholders.

Future Outlook

SEIA’s Outlook for 2025-2030 presents two scenarios:

Base Case: Total solar deployments are projected at 246 GW dc, which is 4% lower than the pre-OBBBA outlook. This scenario assumes that existing projects and increased demand will mitigate the negative impacts of policy changes.
Low Case: Deployments could drop to 202 GW dc, reflecting an 18% decrease due to more stringent permitting and tax credit limitations.

The industry must navigate these scenarios by fostering innovation, enhancing manufacturing capabilities, and advocating for favorable policies to sustain growth.
