US Solar Industry’s Record Growth in 2023 and Upcoming Challenges

The US solar sector is about to hit an impressive mark in 2023. It’s looking at adding a whopping 33 gigawatts (GW) of solar power, which is a hefty 55% jump from what was added in 2022. This surge is mainly thanks to the government’s policies that favor clean energy, resulting in more solar panel installations all over the nation.

Key States Leading Solar Installations

California and Texas are leading the charge in the growth of solar power, while Indiana’s efforts are also impressive. In just the three months of the third quarter of 2023, we saw a boost of 6.5 gigawatts (GW) in new solar power capacity—that’s a solid 35% jump from the year before. What’s more, 14 states along with Puerto Rico each put in over 100 megawatts (MW), with Indiana alone adding a whopping 663 MW, thanks to a bunch of big projects by utility companies.

Residential Solar Segment’s Record Installations

The residential solar segment has shown remarkable growth, installing a record 210,000 systems in the third quarter. However, the California Public Utilities Commission’s decision to significantly reduce state rooftop solar incentives has led to an 80% drop in installations in California.

Economic Challenges and Industry Outlook for 2024

Despite the impressive growth in 2023, the solar industry is bracing for economic challenges in 2024. The SEIA and Wood Mackenzie report anticipates a brief decline in growth next year, influenced by factors like elevated US interest rates and policy changes in California. Nonetheless, the industry is expected to resume its growth trajectory in 2025.

Utility-Scale Segment Challenges

The utility-scale solar segment is facing its own set of difficulties, with the lowest level of new contracts signed in a quarter since 2018. This slowdown is attributed to increased financing costs, transformer shortages, and interconnection bottlenecks. However, improvements in the module supply chain have enabled a record 12 GW of utility-scale deployment in the first nine months of 2023.

Long-Term Prospects and Solutions

Looking ahead, the US solar industry is projected to expand its capacity to 377 GW by 2028, sufficient to power over 65 million homes. This represents a significant increase from the current capacity of 161 GW. However, sustained growth faces challenges like interconnection constraints and transmission capacity issues.

Strategies for Future Growth

To maintain and bolster this growth, experts emphasize the need for interconnection reform, regulatory modernization, and increasing storage attachment rates. These measures are crucial for maximizing the value of solar energy in an increasingly complex grid.

Industry’s Resilience and Innovation

Despite looming challenges, the industry remains optimistic. Innovations in grid calibration and other technological advancements are expected to address some of the bottlenecks in clean energy deployment. Stakeholders hope for governmental action to facilitate smoother transitions and support continued growth.

Impact of Policy and Economic Factors

The significant growth in the solar industry is partially attributed to favorable federal policies, notably the Inflation Reduction Act, which has played a pivotal role in spurring solar installations. However, the industry is not immune to broader economic factors. Interest rates and policy changes, especially in pivotal states like California, directly impact the pace and scale of solar adoption. Balancing policy incentives with economic realities remains a key challenge for stakeholders.

Interconnection and Transmission Hurdles

Solar energy faces a big roadblock because connecting to power networks is pretty complicated, and the transmission lines can only handle so much. With the grid getting more solar-dependent, there’s this pressing need to make the connection setup simpler and quicker. Knocking out these issues is crucial if we want to keep solar energy growing and blend it seamlessly into the main power grid.


In 2023, the US solar business is booming like never before, thanks to favorable policies and tech breakthroughs. Even though there are some hurdles ahead, the sector’s toughness and knack for inventing new stuff suggest it’ll keep expanding and help us towards a greener way of powering our lives. For more information on the US solar industry and its future outlook, visit Wood Mackenzie’s website.
