Solar & Storage Live London 2025: Inside the Event Redefining the UK’s Solar Future

The UK solar and energy storage industry gathered in force at ExCeL London in early April 2025 for the second edition of Solar & Storage Live London — and the results were nothing short of transformative. With around 8,000 professionals arriving on-site over two packed days, the event confirmed its place as one of the most significant clean energy exhibitions on the European calendar.

From breakthrough home battery energy storage systems (home BESS) to the expanding world of Building-Integrated Photovoltaics (BIPV) — including solar roof tiles and facade cladding — the 2025 show captured a sector that is not simply growing, but fundamentally evolving. The conversation on the exhibition floor was less about whether solar would succeed and more about how fast the UK could scale, and who was best positioned to lead that charge.

Home BESS Takes Centre Stage: Why Residential Energy Storage Is the UK’s Biggest Solar Growth

If there was one technology that united the residential solar conversation at Solar & Storage Live London 2025, it was home battery energy storage systems (home BESS). With energy prices remaining elevated and the UK government’s net-zero targets pressing ever closer, the demand for intelligent, affordable home energy storage has never been greater.

Key Home BESS Themes from the 2025 Show

• Smart energy management: Integration of home BESS with AI-powered energy management systems that predict consumption patterns and grid pricing, optimising when to store or export energy.
• AC vs DC-coupled storage: Growing installer interest in understanding which coupling method best suits retrofit versus new-build solar projects.
• Virtual power plants (VPPs): Discussion of aggregated home BESS networks enabling homeowners to participate in grid balancing and earn revenue from stored energy.
• Battery safety standards: Updated guidance on safe installation practices and fire safety regulations for lithium-ion home storage systems in the UK.

BIPV Solar: The Technology That Is Redefining What Buildings Can Do

While home BESS dominated the residential conversation, Building-Integrated Photovoltaics (BIPV) emerged as the defining technology story for commercial and architectural solar at Solar & Storage Live London 2025. And with good reason — BIPV represents a fundamental shift in how we think about solar energy generation.

Rather than mounting solar panels on top of existing roofs or facades as an afterthought, BIPV integrates photovoltaic cells directly into the building fabric itself. Roofing materials, facade cladding panels, windows, and architectural glazing all become functional power-generating surfaces — without compromising the visual identity or structural integrity of the building.

For a UK built environment that faces intensifying pressure to decarbonise whilst preserving planning aesthetics in towns, cities, and heritage zones, BIPV is not simply an interesting option. It is becoming an architectural imperative.

BIPV Solar Tiles: Turning Rooftops Into Clean Energy Assets

Solar roof tiles were one of the standout product categories at the 2025 show, generating significant attention from both residential installers and commercial developers. Unlike traditional bolt-on solar panels, solar tiles replace conventional roofing materials entirely — merging weatherproofing, insulation, and energy generation into a single integrated system.

For homeowners in conservation areas or those deterred by the aesthetic impact of conventional panels, solar tiles offer a compelling path to solar generation that sits harmoniously with traditional architecture. Available in a range of profiles and colourways — including classic slate, terracotta, and grey — the latest generation of solar tiles combines high conversion efficiency with durability ratings designed to withstand the UK’s highly variable climate.

BIPV Facade Cladding: Taking Solar Vertical

If solar tiles represent the evolution of the roof, BIPV facade cladding is arguably an even more significant breakthrough — particularly for commercial, industrial, and high-rise residential buildings where rooftop space is limited but vertical surface area is abundant.

BIPV solar facade systems replace conventional building cladding with photovoltaic panels engineered to generate electricity from vertical surfaces throughout the day. Because facade panels collect solar energy continuously — capturing both direct sunlight and diffuse light from sky reflection — they are productive even during overcast UK conditions. And for urban commercial buildings with large glass and cladding footprints, the energy generation potential is substantial.

Beyond energy performance, BIPV facade systems provide additional benefits including thermal insulation, noise reduction, and weather protection — all while dramatically enhancing the visual modernity of the building. In an era where ESG performance and sustainable credentials are increasingly central to commercial property valuations and tenant attraction, BIPV facades offer a triple return: energy savings, carbon reduction, and architectural distinction.

How Solar & Storage Live London 2025 Is Shaping the Direction of UK Solar

The true significance of Solar & Storage Live London 2025 extends beyond what was on display across its sold-out exhibition floor. The event functions as a real-time barometer of where the UK solar industry is heading — and the signals from the 2025 edition were consistent and compelling.

1. Solar Is Going Mainstream — and the Installer Community Is Ready

With over 4,000 installers attending the 2025 show and 60% of all attendees actively buying solar products and solutions, the event demonstrated that solar is no longer the domain of early adopters and large commercial developers. The UK installer community is expanding rapidly, becoming increasingly sophisticated in its product knowledge, and is actively seeking the next generation of residential and commercial solar technologies — including home BESS, solar tiles, and integrated BIPV systems.

2. Design-Led Solar Is Becoming a Competitive Differentiator

The strong interest in BIPV technologies at the 2025 show reflects a broader market shift: solar buyers — whether homeowners, architects, or commercial developers — are increasingly unwilling to accept the visual compromise of traditional panel installations. Technologies that integrate elegantly with the built environment, including solar roof tiles and facade cladding solutions, are moving from niche to mainstream as consumer expectations evolve and planning authorities respond with more nuanced guidance.

3. The Net-Zero Deadline Is Accelerating Urgency

The UK’s net-zero journey is accelerating, and the solar and storage industry sits at its centre. With government policy, public investment, and private capital all increasingly aligned around clean energy transition, the commercial case for solar — and for integrated solutions like BIPV and home BESS — has never been stronger
