Ever since the change in presidential administrations, the US has rejoined the Paris Climate Agreement and President Biden has made hefty commitments toward cutting domestic carbon emissions, mobilizing finance toward clean technologies, and supporting global neutrality goals, earning him the unofficial title of the Climate President in certain circles.

Amidst these policy commitments, the US solar industry is growing at record rates with over 102 GW of solar capacity already installed and the solar market being valued at 25.3 billion dollars. From here, strides in solar are projected to only increase threefold in the next decade with more and more people getting their energy from clean sources.

Now, here’s our list of influencers in the US photovoltaics space. It is worth noting this list is not a ranking, but rather a collection of some names we think are setting in motion some of the biggest projects, most powerful initiatives, and catalyzing ideas within the solar industry through the positive work of their organizations and platforms.

Watch the recording of our webinar with Sarp Ozkan, VP at Enverus, and Gabriel Cañadas, Senior AE at RatedPower, to learn about the potential benefits of the Inflation Reduction Act (IRA).
