Insight

The UK’s solar sector is entering a period of rapid growth. With more than 21GW of solar capacity already installed and an ambition to reach 45–47GW by 2030, the market is set to more than double over the next five years. This growth is being driven by Clean Power 2030, demand for energy security and the need to decarbonise electricity generation.

For many businesses, however, the opportunity is often viewed too narrowly. Solar is frequently associated with the manufacture or installation of panels, but the wider economic opportunity lies in the supply chains that support deployment.

A recently published report, Growing the UK Solar Supply Chain – A Practical Guide for Businesses, produced by Optimat and Shaw Marketing & Design on behalf of the Department of Energy Security and Net Zero (DESNZ), highlights the breadth of opportunities available to manufacturers, engineers, technology companies, construction firms and service providers across the UK.

A Market Much Bigger Than Solar Panels

Every solar project depends on a complex network of suppliers and specialist services. Alongside photovoltaic modules, projects require electrical infrastructure, mounting systems, steel structures, cables, switchgear, batteries, civil engineering works, software platforms, monitoring systems, operations and maintenance services and eventually recycling and end-of-life solutions.

As a result, businesses that may never have considered themselves part of the renewable energy sector could already possess capabilities that are directly relevant to the growth of solar energy deployment in the UK.

Companies working in advanced manufacturing, electrical engineering, steel fabrication, construction, digital technologies, AI, logistics and professional services all have transferable skills that can be applied to this expanding market.

Playing to UK Industrial Strengths

It is unlikely that the UK will become a major low-cost producer of conventional solar panels, given how concentrated and competitive global manufacturing has become.

However, the UK has genuine strengths and there are significant opportunities in areas including:

• Balance-of-system components such as mounting systems, inverters, power electronics and electrical equipment
• Engineering, Procurement and Construction (EPC) services
• Grid connection and electrical infrastructure
• Digital technologies, data analytics and artificial intelligence
• Operations, maintenance and asset management
• Recycling, refurbishment and circular economy services

These opportunities build on existing UK expertise in engineering, manufacturing, energy systems and innovation. As solar generation becomes a larger part of the energy system, demand will grow for smart monitoring, predictive maintenance, energy forecasting and optimisation tools. Some of the fastest growing opportunities may, therefore, lie not in generation itself but in managing and optimising renewable assets.

Innovation Creates Additional Opportunities

The UK also has strong research capabilities in novel photovoltaic technologies, energy systems integration, advanced materials and power electronics, supported by universities, Catapult centres and innovation programmes.

This creates opportunities for established manufacturers as well as SMEs developing innovative products, software platforms, AI applications or next generation technologies.

Examples include solar tracking systems and lightweight solar films for applications where traditional panels may not be suitable, demonstrating that innovation extends far beyond the panels themselves.

Finance and Support Are Available

One barrier often cited by businesses considering entry into clean energy markets is uncertainty around funding.

Encouragingly, there is a growing ecosystem of support available through Great British Energy, the National Wealth Fund, the British Business Bank, UK Export Finance and regional development agencies. Innovation funding is also available from Innovate UK, Horizon Europe and devolved nation programmes.

While navigating these mechanisms can be complex, the direction of travel is clear: government and industry both recognise the importance of strengthening domestic supply chains and increasing UK participation in renewable energy markets.

The Importance of Supply Chain Resilience

Recent geopolitical events have highlighted the risks associated with over-reliance on global supply chains for critical technologies.

Strengthening domestic capability can improve resilience, reduce delivery risks, create skilled jobs and support regional economic growth. The UK Government’s Solar Roadmap explicitly recognises the need to develop stronger domestic supply chains alongside increased deployment.

For businesses, this is not simply an environmental agenda. It is a commercial opportunity driven by long-term market demand, infrastructure investment and energy system transformation.

The companies that benefit most may be those that move early, identify where their existing capabilities fit within the solar value chain and position themselves as trusted partners in a rapidly growing market.

A Supply Chain Opportunity Hiding in Plain Sight

The UK’s solar ambitions are considerable but achieving them will require much more than installing additional panels. It will require businesses providing products, services, expertise and innovation at every stage of the value chain.

For manufacturers, engineering firms, technology providers and service businesses, the question is not whether the solar market will grow, because the evidence suggests it will. The more important question is whether organisations are ready to capture the opportunities that growth will create.

At Optimat, we believe the greatest value often lies in understanding how industries connect, where supply chain gaps exist and how businesses can position themselves to respond to emerging market opportunities. Solar energy presents exactly that kind of opportunity.
