Tempe, AZ, USA – Erthos, Inc., an energy technology company focused on breakthrough advances for
utility-scale solar, today announced the commercial operation of four more Earth Mount Solar™PV
projects in California. Developed by White Pine Renewables, the projects were acquired by Directional
Services, Inc. and built by OneSun Power Inc. Energy from the plants will be purchased under power
purchase agreements by Teapot Dome Water District and Olam Food Ingredients.

Earth Mount Solar power plants are built without steel mounting systems, such as trackers, and are
instead built by placing solar modules directly on the earth. With this method of installation, Erthos plants
produce more than twice as much energy on the same area of land at a significantly reduced price per unit
of energy.

“Erthos technology is truly a step forward in solar technology innovation. By executing on the Olam Food
portfolio, Erthos has demonstrated an ability to turn projects that would not have worked with a
conventional racking solution into viable assets using its innovative technology. White Pine has been
proud to partner with Erthos over the past two years to ensure that we deliver for our customers – even in
the most challenging circumstances,” says Michael Kremer, Managing Partner and Co-Founder at White
Pine Renewables.

“This marks another stage in our rapid market adoption,” says Jim Tyler, CEO of Erthos. “As with our
first deployment a year ago, with these new projects online, we are seeing immediate and continued
validation of our plant performance. Energy production, thermal performance, and the efficacy of the
ErthBot cleaning robot are all supported by the data coming in from these plants,” says Tyler.

Erthos expects to have over 40 MW of additional projects under contract by the end of the year and is
actively helping developers assess the benefits of Earth Mount Solar PV on over four gigawatts of project
pipeline.
