How solar is delivering energy security – with Timothy Shen and Dr. Rethabile Melamu

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.
