I research solar engineering, economics, and energy science using tools of system dynamics modeling, technoeconomic analysis, and stakeholder engaged design to explore questions of photovoltaic power generation, and solar ecology ( I develop ground monitoring technologies for solar irradiance to better inform my modeling for system performance. My work with community-led solar is an example of real-world stakeholder engagement, facilitating workshops to guide decision making, systems design, and policy planning. My scholarly work has contributed to the National Association of Engineering’s Grand Challenge (USA): “Making Solar Energy Economical,” including 37 peer reviewed publications, 28 non-refereed/conference publications, 2 patents, 1 book chapter: System Integrated Photovoltaics (SIPV), (Routledge; 2012), and a 16-chapter textbook: Solar Energy Conversion Systems, (Academic Press; 2013). Speaking invitations at 25 events among civic, academic, and research audiences have been opportunities to share the potential for solar in jobs, education, and global industry growth. Locations include venues across the USA, Burkina Faso (Keynote Speaker, AfricaSolar 2015), China, Germany, Mexico, and the UAE. As conference chair, I also contributed the closing plenary for the 44th Meeting of the American Solar Energy Society (2015).

Research Projects: 

My skill to cultivate creative enterprise from small beginnings has grown in my time at Penn State. I published results of a short technoeconomic analysis of solar photovoltaics on medium-sized multi-tenant buildings, which included exploring solar goods and services as common pool resources (Brownson, Buildings 3 (2013), 659-673). Building rooftops have limited access and minimal distributed value for renting tenants seeking solar power. Shared solar projects developed offsite could offer power to residents in urban contexts. I hypothesized that an integrative design process (traditionally used for green buildings) would catalyze emergent community solar projects when co-produced by the community. I leveraged $56k in competitive funding from the Penn State ReInvention Fund to establish a living laboratory for a cycle of community engagement workshops in the State College-University Park area. “Community Solar on State” was a transdisciplinary co-creative workspace (in keeping with the use of “transdisciplinary” by the Belmont Forum and Future Earth). By 2018, two large community solar projects emerged from our work—2.6 MWdc community farm at the wastewater treatment authority and 2.0 MWdc on the University Park campus. These community-led solar projects began a new research arc into the role of workshops as finite repeated cooperative games, catalyzing the formation of locally-defined and locally-managed common pool resources. The open process and subsequent research arcs are documented at Academic outcomes included two Schreyer Honors theses, two conference presentations, an upcoming paper (in progress—assessing community-led solar and group agent-based impacts on outcomes using the model of finite repeated cooperative games), and a M.S. thesis.

My successes with integrative design, common pool resource management, and creative enterprise were leveraged again to guide and facilitate statewide workshops for “Finding Pennsylvania’s Solar Future,” a DoE SunShot Initiative project. In this ongoing effort, I was funded $50k (the sole academic partner within the core team). We applied the integrative design process among 500+ diverse stakeholders from multiple sectors. Stakeholders explored likely pathways for photovoltaics to support 10% of in-state electricity demand by 2030, an increase 10-fold greater than present values. Pathway exploration included evaluating strategies using system modeling of associated economic, environmental, and health impacts. The draft plan now includes strategies to incorporate community solar across the state (as well as residential/commercial and utility scale solar). The collective findings of all of these integrative design results were presented at the 4S 2018 Conference in Sydney, Australia (“Commons Wealth: Integrative Design Catalyzing Community Solar from Uni, to Muni, to State”).

Most recently, I have been part of a funded team for the NSF Research Traineeship program (Sr. Personnel), bringing my work in solar ecology together with landscape ecology and landscape architecture. The $3M funded proposal is “NRT-INFEWS: Landscape-U, Impactful partnerships among graduate students and managers for regenerative landscape design” (PI: E. Smithwick, PSU). I am eager to continue more transdisciplinary works.
