The Solar Journey Podcast

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). PLUS: On the Espresso segment, Sven Albersmeier-Braun reports from the new Solar & Storage Live Zürich event. Sven is from upstart Chinese power electronics and battery supplier Sigenergy, and he describes how the residential battery market in Switzerland is undergoing a transition, as fears of power shortages begin to fade.

We're kicking off Season 2 of The Solar Journey with solar industry leader Howard Wenger, President of Nextracker! In this episode, host Dr. Torsten Brammer dives deep into Howard's incredible 40-year journey, from waiting in gas lines during the 1970's oil crisis to leading one of the world's most innovative solar tracker companies. Howard shares how he fell in love with photovoltaics (spoiler: he may bleed silicon!) and never looked back. He walks us through the early days of solar, when costs were sky-high, and people thought he was chasing a pipe dream. Fast forward to today, and Nextracker is celebrating 100 gigawatts of solar trackers shipped. Get a behind-the-scenes look at what drives Nextracker's success and hear Howard's insights on what it will take to push solar energy and clean tech to the next level. PLUS: On the Espresso segment, Radovan Kopecek from ISC Konstanz joins us live from Anaheim, California – from the RE+ trade show and conference. He provides an update on solar manufacturing in the US and how intellectual property issues are creating challenges for prospective cell producers in the country. He also hints at an opportunity for non-Chinese cell makers that may present a profitable sales channel in the currently challenging market situation.

Episode #007 of The Solar Journey Podcast is a little different than our previous episodes. Our honored guest is Alexandra Münzer. She was introduced to us as the “Mother of European Guarantees of Origin,” and we used the opportunity to take a deep dive into a very complex topic: The scope and application of the Guarantees of Origin (GOs) System (also known as green certificates) in Europe. We peppered Alexandra with questions about the purpose, practical application, and possible shortcomings of the GO-System. This system is at the heart of Europe’s goal to become the first carbon-neutral continent by 2050. We learned a lot and are excited to share these fundamental insights with our listeners. Alexandra Münzer is the Managing Director of Greenfact. Greenfact is a market intelligence and price transparency service in the renewable energy industry. She holds a Ph.D. in physics with a special focus on semiconductor sensors, from TU-München. Alexandra was born in Austria, studied in Germany, and now lives in beautiful Oslo, Norway.

In this episode, we had a chat with Swiss national Luca Pedretti. Luca has a vast background as an energy trader and held various positions at EGL and Axpo. One of his first tasks working for a utility was to assist in negotiating a PPA for the first 100 Megawatt wind park in Poland. It was then that he realized that PPA's are going to become the driving force for furthering investments in renewable energy. Luca has dedicated his career to the development and negotiation of PPAs and has been riding the PPA boom in the last couple of years.  Luca is the co-founder and COO of Pexapark, the Swiss fintech startup. They specialize in providing risk management and energy trading expertise as well as software tools to the energy investment market.  Connect with Luca on LinkedIn. Show notes Interesting points covered in this episode for those of us on our own Solar Journey - Why did Luca dedicate his career to the creation of PPA's? - How is it that PPA's are a critical requirement in obtaining project financing of a renewable asset? - What is the critical difference in the EEG feed-in tariff and certificate-based systems in other countries? - How does the core business model of Pexapark works? - What are the biggest challenges in the energy investment market? - What are the factors influencing the electricity price in a PPA? - What are the risks in a PPA transaction and how do they interact? - What's a surprising side effect of the advent of PPA's? - What is the required change in thinking to achieve a world that is power with 100% renewable energy? ** Find this episode's transcript on The Solar Journey website > Blog > Interviews **
