Erthos & Capricorn Close $17.5M Series B Financing

Funds to Accelerate Earth Mount Solar™ PV Adoption & Development


Tempe, AZ, USA – Erthos, Inc., a solar energy technology company focused on breakthrough advances for utility-scale solar, today announced the closing of its $17.5M Series B financing round, led by Capricorn Investment Group, known for investing in iconic companies including Tesla and SpaceX. The investment was made by Capricorn’s Technology Impact Fund, a venture capital partnership that invests in companies developing novel technologies and business models to propel a new wave of renewable companies and infrastructure. Aimed at accelerating market entry, the funds will be used to double headcount and to support further product development in the areas of robotic cleaning, system analytics, and modeling software.

“We see in Erthos a unique opportunity where simplicity and speed to market is coupled with an enormous ability to effect change,” says Ion Yadigaroglu, partner at Capricorn. “Additionally, declining module prices, increasing steel prices, and rampant supply chain problems are creating enormous tailwinds for Erthos.”

In 2019, Erthos raised $7.4M in Series A financing, which helped launch the company, finalize the development of its Earth Mount Solar™ PV system architecture, launch its autonomous cleaning robot, and secure its first portfolio of projects. With its Series B financing, Erthos is set to scale with over 2.5 gigawatts of active project pipeline.

“With this financing, we have the resources to execute phase two of our market rollout,” says Jim Tyler, CEO of Erthos. “With experience in solar technologies, solar development, artificial intelligence, and autonomous devices, Capricorn brings strategic advantages. We are excited to have Capricorn in the Erthos family and look forward to this next phase of execution.”
