S205: "Going Big, Offgrid" with Ndiarka Mbodji

This week's episode of The Solar Journey takes us to sub-Saharan Africa with Ndiarka Mbodji, CEO and founder of Kowry Energy, as the company rolls out sustainable energy solutions across the continent.

Ndiarka's background in chemistry and business management, plus a 15 year tenure in the corporate world at Rolls-Royce, led her to excel in operational roles. But it was her deep connection to Senegal, and her goal of helping the people there gain economic sovereignty, that led to her career shift to renewable energy. She shares how her experiences of going back and forth between Europe and Africa sparked a realization about the vast disparity in energy access—and why the future of development in Africa lies in affordable, reliable power.

With Kowry Energy, Ndiarka envisions energy as the "new currency for economic development," linking Africa's prosperous past with its bright future. “The number one thing you need is energy,” she emphasizes, discussing her company’s mission to foster economic sovereignty for rural communities through reliable, scalable off-grid solutions.

Throughout the conversation, Ndiarka touches on the challenges and opportunities of running a startup in a market as complex as Africa, how her corporate experience shaped her approach to leadership, and the critical role of quality in delivering long-term impact.

PLUS, in the Espresso segment Radovan Kopecek touches base to discuss the latest in manufacturing news from India and Europe, along with the IP disputes that are increasingly entangling TOPCon manufacturers.

S204: "PV Papa" with Martin Green of UNSW

This week Torsten sits down with one of the most influential voices in the solar research community, Martin Green, aka “the father of modern PV,” for a retrospective look at the early history and rapid progress of solar technology.

Martin’s groundbreaking work has shaped the industry as we know it, and his story is one of innovation and grasping opportunities as they arose. His early interest in microelectronics in Australia in the 1960s led to developing world-record-setting solar cells in the 80s. Humble despite these amazing achievements, Martin jokes, “One of my colleagues used to say I was famous in my own lunch box.” But with a ferry in Sydney Harbor set to be named after him, his impact is undeniable.

Martin details his pioneering work with what is now known as TOPCon and with PERC technology – both major breakthroughs in solar cell architecture. Although going against conventional wisdom and in a constant battle to secure funding, his team persevered. His thoughts on the naysayers? “We were told at the time we'd never make it into production. So, yeah, don't listen to the advice that you get given."

Looking ahead, Martin sees potential for even lower solar costs. "We might be looking at a future where solar is not just cheap, but insanely cheap." An icon in the field, his story is a must-listen for anyone curious about how solar became a leading solution in the fight against climate change.

PLUS On the Espresso segment this week, Torsten touches base with another Aussie solar innovator, James Allston from Orkestra Technologies. James is currently in Europe, setting the stage for the expansion of his software startup, and he provides some key takeaways from the recent Solar & Storage Live event in the UK.

S203: "Don't Call it a Comeback" with Gunter Erfurt

In a special extended episode of The Solar Journey, Torsten Brammer speaks with influential industry voice, Gunter Erfurt, former CEO of Meyer Burger Technology AG, in his first interview since parting ways with the European manufacturing giant.

From his beginnings as a student of physics to one of the most well-known faces in Europe's solar manufacturing segment, Gunter's solar journey has taken him to unexpected places. He opens up about Meyer Burger’s bold pivot to solar cell and module production, how policy delay and eventual inaction represents a missed opportunity for Europe, and his vision for the future of solar manufacturing (spoiler: he's still hopeful).

Despite his persistent optimism, he doesn’t shy away from discussing the tough lessons learned, how younger German solar companies opposed pro-manufacturing policies, and why China’s solar dominance represents a risk to global energy security.

Informed and insightful, Gunter does not take a backwards step in defending the strategic decision to transition Meyer Burger's business toward making modules. "I decided let's go for it, and I have never regretted it."

PLUS: On this week's Espresso, Torsten speaks with Ivona Kafedjiska, a PV research strategy and policy consultant with the Helmholtz-Zentrum Berlin, on the sidelines of the EU PVSEC event. She shares some of her key takeaways from the leading European academic conference for clean technology and gives her view on why hopes for a revival of solar manufacturing on the continent may not be lost.

S202: "Data Decoded" with Jenny Chase of BloombergNEF

In our second episode of the season, Torsten is joined at The smarter E in Munich by trailblazing solar analyst Jenny Chase, who was the first member of the BloombergNEF solar analyst team. Jenny, who has spent over 17 years shaping solar market intelligence, shares her journey from studying physics at Cambridge University to leading one of the world’s top sources for solar data and analysis.

Jenny walks us through the early days of solar, back when the price of polysilicon was astronomical and when installing half a terawatt of PV in one year (as we are on track to do in 2024) would've been unthinkable. She reflects on how solar has evolved to become an essential driver of the global energy transition and discusses the many challenges of analyzing an ever-changing and rapidly evolving market.

An extremely engaging conversation, sprinkled with her signature wit and no-nonsense approach, Jenny speaks to the joys of building a team, the perils of management, and the importance of doing what you love (which may or may not include tending to a flock of multi-generational geese).
