Martin Heathcote brings a local perspective rooted in Cleve Hill, where he spent time as a boy working on the land long before the solar farm. In this episode, he reflects on his personal journey from farming and family business into a wider group spanning plant, waste, civils, environmental services and land based operations across the UK.

The conversation explores how Heathcote Holdings grew through practical delivery, long term relationships and a strong people focused culture, while adapting to the demands of utility scale solar. Martin discusses local roots, staff culture, cross group capability and why he sees solar as a long term market shaped not just by construction, but by vegetation management, woodland creation, biodiversity work, land care, monitoring and recurring work over decades.

He also speaks about the group’s willingness to invest in new methods and specialist equipment, including screw piling capability, alongside views on joint ventures, AI cameras, automation and the future of major solar construction. This episode offers a grounded owner level perspective on how local knowledge, family business values and practical investment can help support major solar construction and long term project delivery in the UK.

This episode examines the operational backbone of the utility scale solar industry through a conversation with David Mack, CEO of a group of companies delivering services to solar projects across the UK, Ireland and the United States.

Mack describes growing up on a farm in North Norfolk where his parents attempted to develop a wind turbine project in the 1990s. After his mother passed away when he was 8, the project remained a lasting influence. Decades later he revived the scheme and eventually delivered the turbine in 2022 after years of planning inquiries and legal challenges. The experience shaped his commitment to renewable energy and rural enterprise.

The discussion explores how renewable energy projects can diversify farm income and create employment in rural communities. From this background Mack founded Everblue in 2015, focusing on operational services such as module cleaning, land management and environmental compliance. The wider group now includes SolarYield in the United States, AgriSolar which advises on biodiversity and agricultural integration and Novola, a geospatial platform for managing solar assets.

A central theme of the episode is the operational complexity of large solar farms. Mack explains that scaling operations across gigawatt portfolios requires disciplined systems, training and repeatable processes. Small design decisions such as cable routing or inverter placement can significantly increase maintenance costs over a 30 to 40 year asset life.

The conversation also addresses safety risks associated with photovoltaic systems. Solar farms can appear quiet and low risk but panels operate at high direct current voltages that remain energised in sunlight. Proper procedures, insulated equipment and stronger safety awareness are essential during maintenance activities such as module cleaning.

Finally the episode reflects on the rapid growth of the solar sector, which has expanded to roughly 3 terawatt peak globally and could reach around 75 terawatt peak by mid century. Both speakers emphasise that the long term success of solar will depend not only on construction but on disciplined operations, maintenance and systemised industry practices that can scale worldwide.

In this episode of the Future of Solar Photovoltaics Podcast, Vikram Kumar speaks with Clark Frost of Heathcote Holdings about the civil engineering behind one of the UK’s largest solar infrastructure projects.

Clark shares insights from over 36 years in construction, starting with the UK’s Youth Training Scheme (YTS) and progressing into large scale infrastructure and renewable energy projects. The conversation explores the practical realities of building solar farms at hundreds of megawatts scale, including land preparation, piling, drainage and site logistics.

They discuss working on coastal alluvial ground, installing 12 metre screw piles, managing drainage across agricultural land and coordinating heavy machinery across a thousand acre construction site. The episode also covers the importance of enabling works, health and safety management and the increasing complexity of multi contractor solar developments.

As the UK moves toward much larger solar projects, this discussion highlights how solar farms are evolving into major national infrastructure, combining civil engineering, electrical systems and long term energy investment.

A rare behind the scenes look at how large scale solar farms are actually built.
