Eight Great Women in the Business and Science of Solar

It has been a long, long, long road for the global photovoltaic industry and its participants from its early days with few manufacturers and support primarily limited to oil companies looking for a feel-good business unit to what seemed like its overnight success in the mid-2000s. In 1977 the industry had 1.74 MWp of capacity to produce PV cells. At the end of 2017 the industry had 98 GWp of capacity to manufacture PV cells.

The men and women responsible for the PV industry growth from its beginnings as an oil company hobby to the fastest growing source of electricity in the world often gather at scientific conferences and drink to their old, pioneering days. Working in the PV industry in the 1970s, 1980s and 1990s required more than hope, it required a deep and steadfast belief that the industry would prevail, would become mainstream and would set the tone for the future of electricity generation — because … there was a time when the solar struggle was over whether it would survive as an industry at all.

It is easier to believe in the future of solar today than it was decades ago. This article honors eight of the women who believed and persevered and pioneered the PV industry of today and without who it might be a very different industry indeed.

Each woman has in her own way championed the cause of climate change as well as the cause of the solar industry and has worked tirelessly educating, conducting research and deploying solar technologies to ensure the future of the industry.

This article honors the contributions of women in science and business and whose careers stand as an example to young women around the world of what is possible.

Izumi Kaizuka, RTS, Japan

Of her career, Izumi Kaizuka says: “One of the most significant things about working in the solar industry is that I can see how the industry and the technology are changing the world. Solar energy was once a challenger to conventional energy and now it is a changer, upending the energy paradigm. It is exciting be an analyst in this industry.” Izumi has dedicated her life to the study of the global photovoltaic industry its technologies, business models and deployment. Izumi majored in Chemistry at Tokyo Metropolitan University. After graduation, she joined Lion Corp. as a researcher working in R&D for specialty chemicals for surface modification of polymers and electro conductive materials. In 2003, she joined RTS Corp., PV specialized consultancy in Tokyo established in 1983. 

Since 2003, Izumi has served as the Japanese representative to IEA PVPS Task 1, an international working group for “Strategic PV Analysis & Outreach.” She is one of the authors of Task 1’s key annual report “Trends in Photovoltaic Applications” and provides analysis of global PV industry as well as Japanese PV market trends. Izumi also contributes to global corroboration on PV standards as the duty chair of the national committee of IEC TC82.

The bare facts of a person’s resume do not describe the dedication, the quiet passion, the commitment and joy that person brings to their work. In solar, work is most often a calling.  Izumi is committed to promoting women in business and research and serves as the chair of WinPVJ, Division of Women in Photovoltaics, JSPS 175th Committee on Innovative Photovoltaic Power Generating Systems and PVTTMT, a business women’s network.

The PVSEC Special Award is, along with the Cherry Award and the Becquerel Prize, is one of the distinguished scientific awards in the global PV industry. Over the many years that these awards have been presented there have been few women recipients. The PVSEC Special Award is presented to honor a PV professional’s outstanding contributions for technology development and the promotion of photovoltaic solar energy conversion. The decision is made by the PVSEC organizing committee. In 2017 Izumi Kaizuka was awarded the PVSEC Special Award at the PVSEC-27 held in Otsu, Japan for her tireless commitment to the science and application of photovoltaic technologies. People who work with Izumi describe her as dedicated, of course, and as knowledgeable, patient, willing to sacrifice her time for her industry and friends and a true mentor to young women and men entering the industry.

Renate Egan, UNSW, Australia

Basic research is a creative discipline relying as much on inspiration and ideas as on data, repeatability and experimentation. People who can marry the creative with the technical while focused on the best use of data are rare, and they are crucial to the solar industry.

Currently an Associate Professor at the University of New South Wales, Australia, Dr. Renate Egan leads UNSW’s activity in one of the last remaining bastions of pure research in the solar industry, the Australian Centre for Advanced Photovoltaics (ACAP). In her role, Dr. Egan manages ACAP’s projects and coordinates activities with ACAP’s funding agent the Australian Renewable Energy Agency (ARENA). Her administrative activities include balancing the needs of ARENA with the requirements of ongoing research.

During her career, Dr. Egan has served as managing director of R&D at Suntech Australia as well as CTO and managing director at CSG Solar AG. Her focus is on manufacturing costs, new technology development and the development, management and use of data for better analysis and decision making.

Those who have worked with Dr. Egan say that she has been a passionate and untiring supporter and promoter of solar energy, especially photovoltaics, for decades. Dr. Egan consistently pushes the boundaries of photovoltaic research and the use of better — not just more — data. Dr. Egan is a Co-Founder and Chair at Solar Analytics, a start-up providing software for predicting energy generation from solar energy systems as well as a Partner at Solinno, another Australia-based start-up company that consults in project management, risk assessment, policy and process documentation, IP development and management and project funding.

Dr. Egan’s commitment to the science, engineering and to the analytics required to keep the global PV industry on its trajectory to becoming a mainstream electricity source serves as an example to young women considering a career in the solar industry.

Darlene McCalmont, McCalmont Engineering, U.S.

Of her career, Darlene McCalmont says, “I always say I left the dark side of chemical manufacturing for the bright side of solar even though I feel my operations experience in the chemical industry has played well into why I have been successful in the solar industry. Being part of the solar industry growth has definitely left me feeling good every day about what I do and the contribution to the environment I have made.”

Darlene McCalmont graduated from Ohio State, one of the few women in the late 1970s to earn a degree in Chemical Engineering. Following graduation, she went to work for Celanese Corp., a chemical processing company based in Texas. While in Texas she earned her MBA. She married her childhood sweetheart Tom and they moved to California where Darlene worked for Safety-Kleen, a chemical cleanup company.

Solar installation pioneers often say that they started their business out of their garages and with a truck. After the chemical company was sold and subsequently downsized, Darlene, together with her husband Tom, founded Regrid Power, a solar installation company in the Bay Area. They now run a thriving solar engineering firm, McCalmont Engineering.

People who work with Darlene describe her as detail oriented, operationally excellent, exacting but fair, organized, insightful and thoughtful. One of Darlene’s favorite expressions is “In God we trust. All others bring data,” which pretty well sums up her approach to operations and execution. Her common-sense approach is true to her no-nonsense, Midwest sensibility, farm girl origins.

Common sense and a well-grounded world view is not the whole story; instinct and knowing when to act on it is crucial to business and in life. Back to Darlene’s days working for the California chemical cleanup company; one day a particularly noxious chemical came in to the facility on a truck from somewhere up north. Darlene knew that the chemical was highly dangerous. In the middle of the night her sixth sense kicked in and believing that there was something not-quite-right about this particular truck she went to the facility at 1am to process it through. She was right. The chemical was in the incorrect type of truck to contain it, and it was gradually etching its way through the bottom of the truck.

Terry Jester, COO Solaria, USA & Chairman Silicor Materials, Iceland

In the global solar industry, all roads eventually wind back to ARCO Solar, one of the U.S. pioneers of photovoltaic manufacturing. ARCO was formed in 1977 after Atlantic Richfield acquired Solar Technology International, a company founded by PV industry pioneer Bill Yerkes.

ARCO was the first PV manufacturing company to produce 1 MWp of modules in one year. This may seem small by today’s standards, but this achievement helped put the PV industry on the road to today’s massive scale and lower costs.

Terry Jester, a pioneer in PV manufacturing, began her solar career in 1979 at ARCO Solar as a mechanical engineer working on solar module design and reliability. She has spent 38 years working on producing and refining the cost and performance of solar cells and modules. Her early work focused on creating a product that could be warranted for 25 years, which was accomplished in the late 1980s. 

Terry remained with ARCO through several name and ownership changes, from ARCO’s acquisition by Siemens, to Shell and finally to SolarWorld. She served as a director at SunPower. In June 2008 she joined Hudson Clean Energy as their Entrepreneur in Residence.  Terry joined Calisolar in 2011 as their Senior VP of Operations and stayed with the company through its name change to Silicor Materials leading the company as its CEO and now Chairman.

People who work with Terry Jester describe her as focused on manufacturing excellence and as unfailingly kind, supportive and a wonderful mentor to young women seeking an engineering career. Charlie Gay, director of the U.S. Department of Energy (DOE) Solar Energy Technologies Office, says of Terry, “Terry has been a role model, inspiration and steadfast contributor to the establishment and growth of the PV industry for almost 40 years. I have had the privilege of working with her, since she arrived at ARCO Solar from Cal State Northridge in 1979. One of Terry’s daughters, Rachel, is extending her legacy working on BIPV at Next Energy Technologies in Santa Barbara. Terry’s sense of humor matches her name — Jester — and has been at the heart of her ability to lead organization focus through thick and thin.”
