How solar is delivering energy security – with Timothy Shen and Dr. Rethabile Melamu
The smarter E PodcastShow Notes
Energy security is back at the top of the global agenda and new ways to secure supply are evolving fast. In this episode of The smarter E Podcast, we explore how solar is moving beyond generation to play a critical role in stabilizing power systems and delivering energy security.
First, Wood Mackenzie analyst Timothy Shen breaks down the rapid evolution of solar inverters – and how they are well equipped to meet the challenges of today’s changing power mix. Once seen as passive components, today’s advanced inverters can actively support the grid managing voltage, frequency, and providing reactive power in real time. As the energy transition accelerates, these capabilities are becoming essential to keeping power systems reliable, especially during disruptions.
We also examine what recent grid failures reveal about the gap between older infrastructure and newer, more resilient technologies, and why the latest generation of inverters could help prevent future blackouts.
In the second half of the episode, Dr Rethabile Melamu from the South African Photovoltaic Industry Association shares insights from Africa’s rapidly accelerating solar market. With hundreds of millions still lacking access to electricity on the continent, solar and storage are an increasingly essential factors to support economic growth, energy access, and resilience. From community-led microgrids to innovative financing models, new approaches are enabling decentralized, secure power systems to scale quickly across Africa.

With a focus on smarter inverters and the power of distributed energy systems, this episode looks at how solar is redefining energy security – and why resilience may be its most important role yet.

Germany helped pioneer the political frameworks that made solar a global success. But with daytime electricity prices falling, solar companies under pressure, and significant policy reforms taking shape, could the impressive solar and battery installation rates of recent years slow dramatically?
Europe has some of the world’s best solar researchers and strongest local markets. So why is so much of the PV manufacturing happening somewhere else?
Germany’s utility-scale battery deployment is hitting an inflection point.
The Dunkelflaute has become one of the most persistent arguments against a fully renewable energy system. When the sun isn’t shining and the wind isn’t blowing, where is our energy supposed to come from?
Despite claims that the energy transition is losing momentum, solar and battery deployment continues to run ahead of forecasts – profoundly impacting electricity markets and the wider global energy system.
