John R. Balfour, BS, MEP, PhD, System Conformity Assessment & Resource Expert in the PV Sector of the US National Committee of the IECRE, President High Performance PV. Invested four decades in advancing delivery of more reliable, higher performing infrastructure grade PV/Energy Storage Systems (ESS) to produce greater lifecycle asset value, operational resilience, and cash flow. This work helped bring improvements in system specification, design, construction, and O&M by redefining PV Repowering™ a system engineering (SE)/planning process delivering decades of system Reliability, Availability, Maintainability and Safety (RAMS), risk prevention, reduction, plant and energy optimization strategies. Russell W. Morris, BSEE, MSSE, SM-IEEE, M-INCOSE, is a Retired Technical Fellow in RAM/SE Engineering consultant with over 35 years’ experience in the field of medical, aerospace, and solar power reliability and maintainability and 15 years as an engineer and technician. Responsible for Proposals, Design Analysis, Modeling, Assessment, Allocations and Root Cause Analysis for Reliability, Availability and Maintainability requirements for systems/subsystems such as flight controls, hydraulics, hydrodynamic power generation, PV systems and Solar Arrays, vehicle management systems, navigation, communications, structures, software, one-shot systems, and propulsion systems. He has addressed professionals and students at the University of Texas, AIAA, IEEE PVSC, IEEE IRPS, IEEE ISSRE, ARS and several symposia and Universities in the U.S. and China. He has also taught RAM topics for Boeing suppliers in Italy, England, India, Australia, and multiple sites within the United States.
