Photovoltaics Division

John Burke – Chair 2019 – October 2024

Bio – I have been actively involved with Maine Solar Energy Association (MESEA) since 1990, and on the board since 2000. I continue with my d-i-y solar PV activities with SEADS of Truth, Inc (1980) and DAD Solar, Inc (2011), non-profit solar educational corporations. I have presented hundreds of ‘hands-on’ solar assembly workshops (PV and Thermal), with the general public; junior and senior high schools; as well as other interested groups, across the country and around the world, since 1980. I facilitated the effort to establish MESEA as a full state chapter of, with Dr. Richard Komp. The Downeast Solar Center in Jonesport, Maine, has a history that includes passive solar building practices (1985), international ‘intern program’, as well as many solar assembly and ‘off-grid’ installation workshops. We are continuing with activities to promote understanding and utilization of Solar Energy and self-reliant lifestyles. I have a BFA (Fine Arts) degree (1974), from the Univ. of Hawai’i, Manoa. I’m working on a book that combines the Art and Solar aspects of my life. I have been involved with anti-nuclear and Peace actions since 1970

Rich Stromberg – Vice Chair  October 2022 – October 2024

Bio – Rich Stromberg first became intrigued with off-grid living when a subversive classmate brought a copy of The Whole Earth Catalog to elementary school. Rich acquired his first solar panel (a Sharp 80-watt module) in 2005 and has been living off-grid since then – first on a small ranch on the east side of the Sangre de Cristos, then at an old homestead in southcentral Alaska and now back at the Colorado ranch. After a two-decade career in the semiconductor industry, Rich worked at the Alaska Energy Authority running the state’s solar and wind energy programs. He holds a BS in math/compsci, BA in journalism and a Master in environmental management. His current doctoral studies are focused on the reuse of solar photovoltaic systems for social and ecological benefit which is based on his work as a co- founder of the Equitable Solar Solutions™ program at Coldharbour Institute, based in Colorado. His intended focus on the PV technical division is to engage system owners (residential, commercial, large commercial and utility) on performance, reliability and circular economy pathways.

Debbie Coleman – Vice Chair

Bio – For over 40 years, I have been a passionate proponent of residential passive solar energy! When a home uses less heating energy by taking advantage of the free heat of the sun, then the PV system can be much smaller. My company, Sun Plans, founded in 2002, provides passive solar house plans and custom home design services for clients throughout the U.S. and Canada. Hundreds of homes have been built according to the passive solar heating and cooling principles illustrated in my book “The Sun-Inspire House: house designs warmed and brightened by the sun” first published in 2005. The principles are rooted in the early Passive Solar Design Strategies: Guidelines for Home Building that were developed by Doug Balcomb, an early passive solar pioneer, in association with PSIC, NREL, DOE and many people associated with ASES. Since 1984, I have been a registered architect and currently hold registrations in Alabama and North Carolina. In other states, I provide residential design services. My Bachelor of Architecture was received from the University of Arizona where I gained the fundamentals in sustainable and energy education. Passive solar heating and passive cooling elements were part of the design process and not something that could be tacked onto a building or set of plans at the end. I am a LEED G.A. and believe that sun-inspired design is the gold lining of green building. Taking advantage of the free heat of the sun to warm buildings in winter is low hanging fruit for energy-savings. In 2015, I completed the Zero Net Energy Home Design course by Marc Rosenbaum, P.E., Energysmiths where I logged over 200 hours exploring the details of what it takes to design a zero net energy home. Homes built from my designs have been on the National Solar Tour for over 20 years across the U.S. I have been published in Fine Homebuilding, Solar Today, Mother Earth News, Home Power, and Home Energy. I have presented papers, posters and seminars on passive solar design in the U.S. and Canada. I was the general contractor for my previous sun-inspired home and assisted with the renovations of my current one. These construction projects have given me experience in the construction details of high-performance, low-energy homes. In both homes, the energy consumption typically averages around 700 kWh per month for the home’s energy use with about 1/3 being the heating/cooling portion.

Solar Thermal Division

Henry K. Vandermark – Chair 2014 – October 2023

Bio – Henry K. Vandermark founded Solar Wave Energy in 1978 where he has been involved in design, installation and service of solar thermal systems including site-built and factory-built collectors. He spent 30 years installing and servicing many types of solar hot water systems used in the Northeast U.S. and brings detailed analysis and that hands-on experience to solar monitoring. He currently oversees the team that has built and operates , a web-based solar thermal monitoring platform designed to help installers optimize performance, manage service of solar thermal systems and provide reports for performance based incentives program, Thermal PPAs, and company fleets. Monitoring experience includes conventional solar thermal systems with flat-plate and evacuated tubes panels as well as hybrids (PV-Therms/PVT) panels combining thermal and electrical production. He has taught conference workshops, trade school classes, and programs for science teachers. He continues to consult on solar thermal designs for building applications and portfolio management using the monitoring platform as a Lifetime Commissioning tool to optimize efficiency. He is the board chair of the Boston Area Solar Energy Association, member of ASES, ISES, NESEA, SEIA (Solar Heating and Cooling Alliance) and participates in several working groups and forums such as those of the International Energy Agency (IEA) Solar Heating and Cooling Programme), Solar Thermal R&D and the Solar Desalination Forum.
