Erthos Secures Additional $24 Million in Equity Financing

Capricorn’s Technology Impact Funds Spearhead the Round


Tempe, AZ, USA – Utility-scale solar trailblazer, Erthos, today announced securing $24 million in funding, led by Capricorn’s Technology Impact Funds. The investment will accelerate the company’s growth, addressing the surge in demand and supporting upcoming large-scale projects.

“After showcasing two years of outstanding performance data, we’ve demonstrated our technology’s reliability, leading to significant market demand,” states Charles Pimentel, President and Chief Commercial Officer at Erthos. “This capital ensures we can meet this demand with confidence.”

Boasting over two decades in impact-aligned investments and managing approximately $9 billion in assets, Capricorn is celebrated for early stakes in industry leaders like Tesla and SpaceX.

Ion Yadigaroglu, Partner at Capricorn, shares, “Erthos stands out in its potential to revolutionize solar cost-effectiveness. Their vastly simplified supply chain, rapid construction, reduced land use, and lower equipment and labor costs are unparalleled. Their two years of field data confirm their energy performance. The resilience displayed by their California power plants, enduring one of the harshest recent winters, further impressed us. We’re thrilled to back them.”

Recently, Erthos highlighted the acquisition of a 34-MW project portfolio spanning five US states, introduced an investment-grade performance guarantee for Earth Mount Solar® PV systems, and secured a contract for a 180-MW project in Mississippi.

Erthos invites interested parties and media representatives to their exhibit (booth 28048) at the annual RE+ solar trade show in Las Vegas, Nevada, September 12th through 14th.
