Earth Day and Beyond: How Solar Roofs Are Shaping the Homes of Tomorrow

As we celebrate Earth Day and reflect on the urgent need for cleaner, greener living, attention is turning to how we build the homes of the future. The proposed Future Homes Standard (FHS) has significantly shifted the focus toward building materials, mandating a reduction in carbon emissions from new homes by 75-80% compared to current Building Regulations. To meet Part L standards, many new homes are incorporating solar systems—particularly when alternative low-carbon technologies like heat pumps are not viable. thereby decreasing dependence on traditional energy grids and delivering substantial environmental benefits along with cost savings.

The FHS proposals have suggested pathways that would strongly encourage or even require solar, though this is not yet a formal mandate. Innovative manufacturers are responding by developing integrated technologies that simplify compliance while enhancing the skill sets of tradespeople. A notable example is wienerberger's Sandtoft in-roof solar panel system, which enables the seamless integration of renewable energy generation during the standard roofing process, all without sacrificing aesthetic appeal.

In-roof solar systems not only aid in achieving necessary emissions reductions, but they also provide a distinct advantage over traditional bolt-on panels: by fusing sophisticated renewable energy generation into the very fabric of the building envelope.

wienerberger’s Sandtoft in-roof solar system provides a streamlined installation process and harmoniously integrates with the roof as part of a comprehensive roofing solution. This includes inverters, batteries, roofing tiles, and accessories, eliminating the need for separate racking or mounting hardware. Each panel, weighing only 8.95 kg, mounts directly onto roof battens, enabling solar power installation alongside standard tilework. This innovation simplifies what was once a cumbersome add-on process, streamlining construction timelines and reducing labour costs.

Critically, such solar roofing systems offer the opportunity for roofing contractors and installers to upskill to meet changing legislation and client expectations - alleviating some of the pressing labour shortage by expanding each tradesperson's capabilities. As regulatory bodies increasingly prioritise sustainability and renewable energy integration, equipping the existing workforce with new skills through accessible training is paramount.

To tackle this challenge, wienerberger provides online tools, services, and specialised training programmes which combine classroom learning with practical experience. For more information on the resources we offer for installers, contractors, and housebuilders alike, see our full support hub.

Last year the new government announced its plan to build 1.5 million homes over the next parliament, with mandated targets for local authorities, will need an industry wide approach that considers both building materials and methods - speed, ease, quality, and affordability will be key. The ‘New Towns Code’ which stipulates a requirement for 40% affordable housing, must deliver well-designed, sustainable, and attractive homes. This commitment to sustainability and affordable housing resonates with wienerberger’s vision for a future powered by renewable energy. If the Labour government were to endorse power-generating materials as part of the FHS, it could further accelerate innovation; however, providing incentives will be vital for encouraging the adoption of modern technologies.

Implementing in-roof solar technology represents a significant step toward sustainable construction, which should be bolstered by comprehensive training and collaboration within the industry. This transition will not only hasten the adoption of renewable energy but also equip the workforce for future challenges.

Looking ahead, fostering collaboration among the government, industry stakeholders, and companies like wienerberger will be crucial for realising ambitious objectives. As we mark Earth Day, it’s clear that embracing sustainable practices and innovative solutions is key to building a brighter, greener future for the UK’s housing market.
