U.S. Solar Energy Trends to Build on in 2025

With the calendar turned to 2025, the solar industry is poised to build on a dynamic year of growth and innovation while confronting some daunting political challenges. Let’s dive into some of the key trends shaping solar energy and take a closer look at the opportunities that lie ahead.

Domestic manufacturing on the rise

The U.S. has made significant strides in domestic solar manufacturing. Incentives from the Inflation Reduction Act (IRA) have driven investment, with nearly five times the domestic module manufacturing capacity since mid-2022. In 2024 alone, five new or expanded factories were established across states like Alabama and Texas.

Looking forward, the U.S. will aim to tackle more complex stages of the supply chain, such as polysilicon and wafer manufacturing, to ensure a resilient and self-reliant solar ecosystem.

Navigating global supply challenges

While global oversupply has driven module prices to record lows, U.S. importers face hurdles such as tariffs, antidumping laws, and compliance with the Uyghur Forced Labor Prevention Act. Tariffs, in particular, remain a contentious issue. Past increases have affected pricing and supply chains, raising concerns about potential new policy shifts. These factors make buying solar panels from overseas more challenging but also emphasize the importance of diversified supply chains and domestic production.

Interconnection bottlenecks

One of the most significant obstacles to utility-scale solar expansion remains grid interconnection. By the end of 2024, over 1,000 GW of solar projects awaited transmission approval. In response, the Department of Energy released a roadmap aiming to streamline interconnection processes, targeting a 70% project completion rate within a 12-month review period. These efforts could accelerate utility-scale development in 2025.

The evolution of residential solar

High interest rates and state-level rulemaking challenges hindered residential solar growth in 2024. However, the industry is adapting by diversifying offerings—from battery energy storage to EV chargers and energy management systems. As these products gain traction, they are expected to reinvigorate the residential market this year.

Resilience in the face of extreme weather

As extreme weather events become more frequent and severe, resilience has become a cornerstone of solar development. Residential solar systems paired with battery storage provide homeowners with reliable backup power during outages, offering peace of mind and energy security. On a larger scale, Puerto Rico recently received an $861 million loan guarantee for two new solar farms and battery storage systems and  utility-scale solar developers are innovating with hail-resistant modules and advanced wind-stow systems. These technologies are particularly vital in regions like Texas, which face high exposure to extreme weather yet remain leading markets for solar energy. This focus on resilience within our energy grids not only safeguards investments but also bolsters confidence in solar as a dependable energy solution.

Expanding market value

The Solar Energy Industries Association reports that solar contributed over 64% of new electricity generation capacity in 2024, with the industry’s cumulative capacity surpassing 220 GW. This expansion underscores the market’s estimated $64 billion value and its pivotal role in the transition to renewable energy.

What’s next for solar?

In 2025, we expect to see continued growth in U.S. manufacturing, improvements in interconnection efficiency, and broader adoption of resilient solar technologies. As policy, innovation, and market demand align, solar energy will remain a driving force in the shift toward a cleaner, more sustainable energy future.
