Professional Specialties and Experience
Dr. Balfour brings over 4 decades experience in organizing, training and managing large and small multi-discipline working groups in PV, energy planning, R&D, transportation, technology transfer, industry consensus building, education and development

His work has been with a broad range of technology and process developers, VC companies, financiers and insurance organizations, universities, international laboratories, standards agencies, volunteer mentoring groups

He has been active as a PV technology and System provider, integrator in EPC and O&M

He has over 40 years experience in the technical areas of energy (PV & solar thermal), transportation (maglev, rail, buss and paratransit), advanced tech transfer and applications, product and project research, market and risk relevance, reduction, analysis and solutions

His primary focus is on:

PV product and system Performance, Reliability and Optimization (PRO) analysis, o Preemptive Analytical Maintenance (PAM) and PV System Relationship Mapping o PV System Design & Application Theory (PV SDAT), a PV systems engineering process for PV system delivery development

Implementation of Reliability, Availability, Maintainability and Safety (RAMS) strategies, models and processes for the PV industry

Dramatically improving the availability and quality of PV industry education, training and experience development in the USA and internationally

For decades, Dr. Balfour has worked closely with PV stakeholders including system owners, asset managers, O&M professionals, architectural and engineering professionals, EPCs, PV system integrators, manufacturers, system financiers and insurers, bonding companies, legal firms, VCs, electrical and water utilities among others to advance the art and science of PV and its applications.

The vast majority of his work it is based on thousands of conversations, hundreds of industry meetings, and many dozens of conference and other professional Industry presentations.

He and his colleagues are actively working towards the development and implementation of the industry wide application of to Industry rating systems:

     Module Risk Priority Number (RPN) and

    Plant Rating Systems (PRS) to determine the true condition and asset value of PV electrical energy generating plants

He is a board member of, and worked as a volunteer mentor since 2001 to the Arizona State University Professional Science Major (PSM) (the Graduate PV Commercialization program)
