At 2024’s Solar & Storage Live in Birmingham, experts discussed key developments shaping the sector with Solar&StorageXtra.
Dr. K.T. Tan, CTO of Viridian Solar and board member of Solar Energy UK (as of January 2025), shared insights on policy changes, technological progress, product longevity, and how the industry should be widening its horizons.
Interview with Dr. K.T. Tan, CTO at Viridian Solar
“The solar PV sector can no longer operate in isolation; we need to look beyond PV modules.”
Xtra: Can you tell us a bit about your presentation at Solar & Storage Live UK?
K.T.: My presentation covered a wide range of topics, from policy and future home standards to fire risks in the PV industry. I also discussed NHBC regulations and their impact on the solar sector, as well as the latest technological advancements in PV systems.
Xtra: How do you see new developments in PV technology impacting the sector over time?
K.T.: The latest advancements in PV technology are typically incremental. For example, we’ve seen a shift from p-type to n-type cells, and now there’s discussion around tandem cells like perovskite.
These improvements enhance efficiency, but research and development efforts also focus on durability – making systems more robust and long-lasting. The longer a PV system lasts, the lower its carbon footprint over its lifetime.
Additionally, advancements extend beyond solar cells to the entire balance of the system, optimising performance and sustainability.
Xtra: What trends should the solar and storage industry be paying closer attention to?
K.T.: Cost is always a primary concern, but I believe industry professionals should also focus on quality and longevity.
Modern PV products can easily last over 25 years, if not longer, so choosing the right products for long-term reliability is crucial. Evaluating only the upfront cost tells just part of the story – understanding the underlying technology is essential.
While some aspects of PV technology may seem complex, the fundamental principles of photovoltaic electricity generation have remained largely the same since 1954.
Xtra: Why should companies and professionals attend Solar & Storage Live UK?
K.T.: This year’s event has doubled in size, which is exciting. However, beyond size, what stands out is the diversification of technologies being showcased. I’ve noticed an increasing presence of AI-enhanced tools and other innovations that complement the PV industry.
The solar PV sector can no longer operate in isolation; we need to look beyond PV modules to consider mounting systems, balance of system (BOS) components, operations and maintenance, and even end-of-life recycling.
A holistic approach is key, and this year’s show effectively integrates these elements, making it a valuable event for industry professionals.
