How much solar capacity did the residential segment install in Q1 2025?

Storage Supply Chain

How many solar modules have been added in 2024?

Since the IRA’s passage, more than 95 GW of manufacturing capacity have been added across the solar supply chain (from facilities announced pre- and post-IRA), including nearly 42 GW of new module capacity. U.S. c-Si manufacturers added significant capacity in the first half of 2024.

Does community solar capacity exceed our near-term outlook?

Community solar capacity under development and construction significantly exceeds our near-term outlook. New York and Illinois alone have a community solar pipeline totaling nearly 5 GWdc as of Q1 2025. However, due to lengthy interconnection studies and grid upgrades, we expect only a fraction of that capacity to come online each year.

How much solar capacity did the residential segment install in Q1 2025?

Utility-scale projects dominated installations in both states. In Q1 2025, the residential segment installed 1,106 MWdc of solar capacity, declining 13% year-over-year and 4% quarter-over-quarter. High interest rates and economic uncertainty continued to suppress demand.

How much solar capacity did the US solar industry install in Q1 2025?

The US solar industry installed 10.8 gigawatts-direct current (GWdc) of capacity in the first quarter of 2025. Despite both a quarterly and annual decline in capacity, Q1 2025 was the industry’s fourth-best quarter. The utility-scale segment followed a similar trend, with 9 GWdc of capacity, which is lower than both Q1 2024 and Q4 2024.

How many solar modules are there in the US?

The US added 8.6 GW of solar module manufacturing capacity in Q1, bringing the total to 51 GW. However, growth in upstream manufacturing capacity remains slow or non-existent. ES Foundry became just the second domestic cell manufacturer when it opened a 1 GW cell factory in South Carolina in January.

How can a probability map show where solar fields are likely to occur?

Based on the location of solar fields that have been developed in the past, a probability map can be made that shows where solar fields are likely to occur in the future. To do this, the coefficients and the constant will be filled in using the formula shown in Appendix B.3.
