Director of R&D

Willie Hammack is a five-year veteran of the utility-scale solar industry now at his second solar startup company. With a degree in Electronics Engineering and a master’s degree in solar energy and commercialization, Willie brings innovative approaches to the projects and products in his sphere. He began his professional career as a field engineer at DEPCOM Power, a solar EPC company, and within one year quickly moved up into the position of the companies’ sole operations engineer. His main focus in this role was to increase construction productivity by deploying a multitude of innovative and self-created in-house tools and processes. Developed in-situ, these tools yielded some of the lowest manhour per megawatt construction production numbers the industry had seen at that time for industrial solar construction. Willie is now using his creative design and engineering talents to further Erthos’ product development efforts.
