Solar Ireland: Delivering solar where life happens

Beyond national targets and policy documents, the true test of Ireland’s energy transition lies on the roofs of our homes, farms, and businesses. SEÁN SHERLOCK, Director of Policy & Regulation, Solar Ireland, explores how the building services sector holds the key to “solar where life happens”—and why designing for solar-readiness is now a fundamental responsibility for the industry.

When solar energy is discussed in Ireland, the conversation often centres on national targets or large infrastructure projects. These milestones matter. They show progress and signal ambition. But the real test of Ireland’s solar transition will be much closer to home.

It will be seen on the roofs of houses, farm buildings, schools and small businesses across the country. It will be reflected in lower electricity bills and greater control over energy costs. Most importantly, it will be measured by whether the benefits of solar reach people in their everyday lives.

For the construction and building services sector, this creates both an opportunity and a responsibility. The professionals who design, build, and retrofit Ireland’s buildings will play a central role in determining how quickly and how fairly solar energy reaches the places where people actually live and work.

Solar should not remain something that exists mainly in policy documents or national infrastructure plans. It should be delivered where life happens.

 

Rooftop solar at scale

Ireland has already made significant progress in deploying rooftop solar. According to the latest figures from the ESB, more than 170,000 rooftops across the country now generate electricity, including homes, farms, schools and commercial premises.

This progress demonstrates what can be achieved when policy frameworks, industry capability and public engagement move in the same direction. Reaching the next stage of deployment will require continued attention to three practical areas: ‘Access’, ‘Standards’, and ‘Delivery’.

Access remains fundamental. Support schemes have enabled many households and small businesses to invest in solar for the first time. Maintaining stable and predictable frameworks will remain important if rooftop solar is to continue expanding across society.

Standards and quality assurance are equally important. As installations increase, maintaining strong technical standards protects consumers and ensures systems perform reliably over their lifetime. Skilled installers, clear certification pathways and consistent technical guidance are essential.

Delivery capacity must keep pace with demand. Engineers, electricians, installers and building professionals are the people who translate policy ambition into functioning systems on real buildings.

 

Designing buildings with solar in mind

One of the simplest ways to accelerate solar deployment is to ensure buildings are designed with solar in mind from the outset.

When solar is considered during the design phase, installation becomes easier and more affordable. Roof orientation, structural loading, electrical capacity and space for inverters or batteries can all be incorporated with relatively minor adjustments when addressed early.

For building services engineers, this means thinking about solar as part of the wider building energy system. Integrating rooftop solar alongside heat pumps, EV charging infrastructure, and smart energy management systems can create buildings that reduce operating costs while improving energy performance.

Designing buildings that are solar-ready also improves affordability. When the basic infrastructure is already in place, households and businesses can install solar later at a lower cost. This helps ensure the technology remains accessible to more people over time.

Unlocking the potential of commercial and agricultural rooftops

Ireland also has considerable untapped potential across commercial and agricultural buildings. Warehouses, factories, retail centres and farm buildings often have large roof areas and significant daytime electricity demand. These conditions make them well-suited for solar generation.

For many businesses and farms, electricity costs represent a major operational expense. On-site solar generation can provide greater price stability while also strengthening the wider electricity system. Producing electricity closer to where it is consumed reduces network pressure and improves efficiency.

Unlocking this opportunity requires solutions that work for SMEs and agricultural businesses. Financing models, simplified connection processes, and clear technical standards can help lower barriers to deployment.

Solar should not become something that only large corporations can access. It should remain a practical option for the wider economy.

 

Solar and the cost of living

Energy affordability is one of the defining policy challenges of our time. Solar has an important role to play in addressing that challenge, but the way it is delivered matters.

While the long-term benefits are clear, the upfront cost of installation can still be a barrier for some households. Addressing this challenge will require a range of policy approaches rather than relying solely on increased capital grants.

Community energy models, shared rooftop installations, and innovative financing structures can allow households to benefit from solar without needing to own the system directly.

Solar can also play an important role within broader retrofit programmes. When combined with insulation, heat pumps and smart energy management, solar can contribute to meaningful reductions in household energy costs. For lower-income households in particular, combining solar with energy efficiency upgrades can help reduce bills while improving comfort and resilience.

 

Energy security through distributed generation

Rooftop solar also contributes to Ireland’s energy security. Producing electricity closer to where it is consumed reduces reliance on imported fossil fuels and increases resilience within the electricity system.

When combined with battery storage and flexible demand, rooftop solar can support a more responsive and efficient energy network.

For the construction and building services sector, this presents an opportunity to design buildings that participate actively in the energy system rather than simply consuming electricity.

 

Practical actions for the construction sector

Delivering solar where life happens will depend on collaboration across construction, engineering and energy sectors. Three practical actions can help accelerate progress.

• Design buildings that are ready for solar: Ensure roof structures, electrical systems and plant space allow for future solar and battery installation.
• Maintain strong installation standards: High-quality design, installation and certification will protect consumers and support confidence in solar technologies.
• Integrate solar with building energy systems: Combining solar with heat pumps, EV charging, and energy management systems can improve efficiency and reduce energy costs.

 

Solar Ireland’s 2026 Annual Conference

Ireland’s clean energy transition must work for everyone. If solar is to fulfil its potential, it must be accessible across the full spectrum of society, including urban homes, apartment buildings, farms and small businesses across rural Ireland.

These issues will form a central part of Solar Ireland’s 2026 Annual Conference, Energising Life – Decarbonising How We Live. The conference will examine how rooftop solar can scale across homes, farms and SMEs while helping address both energy affordability and energy security.

The conversation about solar is not only about generation capacity. It is about delivering practical solutions that reduce energy costs, strengthen resilience and bring the benefits of clean energy into the places where people live and work every day.
