Meet Your Instructors
Ryan Mayfield
Founder & Owner
Discovering renewable energy while pursuing his degree in Environmental Resources Engineering at Humboldt State University, once Ryan got his hands into PV installation work, he knew exactly how he would spend his future.
Both before and since founding Mayfield Renewables in 2007, Ryan’s successes have blended technical expertise with an affinity for writing and education. While CEO, he doubled as the PV Systems Technical Editor for SolarPro magazine (2010–2018), writing insightful feature articles for both SolarPro and Home Power. Ryan also authored PV Design and Installation for Dummies (2010). He continues to teach national PV courses on topics such as National Electrical Code, Oregon solar code and PV systems, commercial PV systems, and PV-plus-storage. He holds a Limited Renewable Energy Technician (LRT) license in Oregon.
Ryan brings his love of education and codes & standards to the team as well as the wider industry. His humble attitude of constant learning and growth while endeavoring to provide accessible, transparent expertise to improve the solar-plus-storage industry has shaped Mayfield Renewables’ mission.
Ryan lives in Corvallis with his wife, three children, one dog, and enjoys quality time with all of them when not competing in triathlons, traveling, or sipping a good Scotch.
Lucas Miller
Senior Engineering Consultant
As a lifelong climate advocate, Lucas dove into the renewables industry straight out of college by moving from Madison, Wisconsin to Portland, Oregon to join a PV contractor. In the 6+ years since, he has held many roles in the solar and energy storage industry, from marketing and market research to product development and project coordination.
Lucas’s experience blends engineering acumen and industry knowledge with a backbone in content development. Lucas holds a Bachelor of Business Administration from the University of Wisconsin and recently completed a post-bachelor’s in Renewable Energy Engineering from the Oregon Institute of Technology.
Outside the office, Lucas can be found cooking, hiking, playing soccer, and taking too many pictures of his cats.
Tyson Bittrich
Market Research Analyst
Tyson is enthusiastic about the forthcoming energy transition and aims to support renewables solutions-makers. He brings a unique perspective to the Mayfield team holding an M.A. in Philosophy and B.A.’s in Music and Philosophy. He is a teacher at heart; teaching hot yoga, music, and even cocktail and wine training.
Tyson calls Portland, OR, home, where he is finishing his B.S. in Renewable Energy Engineering from Oregon Institute of Technology. His studies focus on electrochemical storage technologies that best empower intermittent RE generation and distributed energy resources.
Beyond work, Tyson is an avid musician leading a jazz quartet since 2019. He is always on the hunt for high-end coffee, tasty food, and vintage vinyl. He and his wife especially enjoy journeying into the green spaces, coastlines, and mountain trails of the great Pacific NW.
Zach Snyder
Senior Engineering Consultant
In 2018, with a background in geology, technology, and education, Zach decided it was solar or bust. After spending a year as a marketer at an Oregon PV installation company, he went on to lead the statewide consumer education nonprofit Solar Oregon. There he developed and managed educational programs and tours funded by the Energy Trust of Oregon to teach home and business owners about the ins and outs of installing solar-plus-storage. Maintaining his techno-chops all the while, in 2022-23 he contracted independently with PV Evolution Labs to develop computer vision algorithms and automation used for PV module quality testing.
As an educator, Zach supports Mayfield’s mission to provide accessible information about solar and energy storage to the industry. As a technologist, he supports Mayfield's commitment to quality through continual process improvements and knowledge engineering. When he is off the clock, Zach loves to travel and read widely and cruise like lightning on his bicycle.
