  1. The Foundation of Utility-Scale Solar

    The Foundation of Utility-Scale Solar

    In this episode of Watt Matters we sit down with Alice Thomas and Seif Gomaa from Solarport Systems, a UK-based manufacturer delivering ground-mount solar solutions across the UK and Europe. Together we explore what really goes on beneath the solar panels — from foundation engineering and site investigations to design optimisation, documentation standards, and emerging innovations like AI-driven workflows, trackers and carport systems. As projects grow in scale and complexity, mounting structures are not just a logistical detail — they are strategic drivers of cost, durability, yield and ultimately project bankability. Alice and Seif walk us through why early-stage due diligence, flexible foundation options, and strong supply-chain relationships increasingly differentiate successful solar developments from risky ones. Takeaways Local manufacturing dramatically reduces lead times and enables rapid spare-part support.Offering multiple foundation types (pile, ballast, gabion, X-anchor, etc.) makes even challenging terrain viable.Thorough geotechnical and topographical site investigations — including corrosion assessment and pull-out tests — are critical for long-term structural integrity.Documentation, code validation and traceability have become non-negotiable requirements for developers and investors.High-quality structural steel (e.g. S450 with advanced coatings) and tailored engineering can extend system life well beyond the traditional 25 years.Detailed 3-D layouts and topography-aware designs help avoid shading, grading or pile-clash issues — improving yield, constructability and bankability.Automation and AI are beginning to support repetitive tasks and QC processes — freeing up engineers to focus on design decisions and risk assessment.Tech is evolving: tracker systems and carport-mounted installations are among future growth areas for mounting providers like Solarport.

    The BESS Revolution, with Swetha Sundaram

    Battery energy storage systems (BESS) have rapidly evolved from a niche technology into a core pillar of the modern renewable grid. As utility-scale solar expands, storage is no longer a “nice-to-have”—it’s essential for delivering reliability and resilience.  In this episode of Watt Matters, Ana speaks with Swetha Sundaram, VP of Solar and Hybrid BESS Systems at RWE Clean Energy and co-author of The BESS Book, to unpack what’s driving this transformation. Swetha shares her insider’s perspective on the evolution of storage—from early pilot projects to today’s 200MW+ systems—and offers practical insights into permitting, design, safety, and revenue optimisation. She also explores how AI and new chemical systems are reshaping what’s possible for grid-scale storage, and why collaboration across communities and regulators is key to BESS success. To learn more about accelerating solar project success and how PVcase supports developers from design to delivery, visit www.pvcase.com. Takeaways BESS has become a critical part of grid infrastructure, not just a solar add-on.Safety and permitting remain top challenges, requiring proactive community engagement.Lithium iron phosphate (LFP) chemistry now dominates for cost and safety advantages.Project scale has increased from 10MW a decade ago to 200MW and beyond.AI and predictive analytics are unlocking smarter battery degradation management.Revenue realisation depends heavily on sophisticated software and dynamic dispatch.Permitting delays can be avoided by early collaboration with local authorities.Standalone storage is thriving post-IRA, enabling new grid and data centre applications.Long-duration technologies like sodium-ion and iron-air show strong future potential.The future of BESS lies in integration—across grids, industries, and digital systems.
