Growth Industry

The adoption of commercial solar energy has swiftly established itself as a major contributor to new electricity generation in the U.S., outdoing both traditional power sources and alternative renewables. In 2023, solar energy represented 55% of all new electric capacity—the largest proportion seen in 80 years. This upward trend continued into 2024, with solar contributing 67% of new capacity thus far. The commercial sector is largely responsible for this momentum, driven by declining solar panel prices, potential long-term savings, and positive environmental impacts. This rapid embrace of solar technology underscores its reliability and essential role in fostering a more sustainable energy future.
