How Solar Technology is Revolutionising Residential Construction in Ireland

The Irish residential construction sector is undergoing a remarkable transformation, driven by an unprecedented shift towards renewable energy solutions. At the forefront of this revolution is solar technology, which has evolved from a niche consideration to a fundamental component of modern home design. As Ireland commits to ambitious climate targets and homeowners grapple with escalating energy costs, solar panels and associated technologies are reshaping how we conceive, construct, and inhabit residential properties across the Emerald Isle.

This transition represents more than a mere trend; it signals a fundamental reimagining of sustainable living in the Irish context. Despite the nation’s reputation for cloudy skies and frequent rainfall, advances in photovoltaic technology and supportive government policies have positioned solar energy as a practical and economically viable solution for Irish households. From Cork to Donegal, solar installations are becoming increasingly commonplace, heralding a new era in residential construction that prioritises energy independence, environmental responsibility, and long-term cost savings.

  • The Evolution of Solar Technology in Irish Residential Settings

Ireland’s journey with solar technology has been relatively recent but remarkably swift. Historically, the country’s overcast climate was perceived as an insurmountable barrier to solar adoption. However, technological breakthroughs in photovoltaic efficiency have shattered this misconception. Modern solar panels can generate electricity even on cloudy days, harnessing diffuse sunlight with remarkable effectiveness. This capability has proven particularly significant for Ireland, where direct sunshine may be limited but ambient light remains abundant throughout much of the year.

The past decade has witnessed dramatic improvements in solar panel efficiency, with contemporary systems converting upwards of 20% of captured light into usable electricity – double the efficiency of panels available just fifteen years ago. Simultaneously, manufacturing advances have reduced costs by more than 80% since 2010, transforming solar from a luxury addition into an accessible option for mainstream homebuilders and renovators alike. This convergence of improved performance and affordability has catalysed widespread adoption across Ireland’s residential sector.

  • Government Initiatives Driving Solar Adoption

Ireland’s regulatory landscape has evolved considerably to encourage renewable energy adoption in residential construction. The Sustainable Energy Authority of Ireland (SEAI) administers several grant schemes that significantly reduce the upfront costs of solar installations. The Solar PV Grant scheme offers homeowners substantial financial support, covering a considerable portion of installation expenses for qualifying systems. This initiative has proven instrumental in accelerating solar uptake, particularly amongst middle-income households for whom the initial investment might otherwise prove prohibitive.

Beyond direct financial incentives, Ireland’s revised Building Regulations now incorporate stricter energy performance standards for new constructions. The Nearly Zero Energy Building (NZEB) standard, mandatory for all new homes since 2020, effectively necessitates renewable energy integration to achieve compliance. Solar photovoltaic systems represent one of the most straightforward pathways to meeting these requirements, consequently becoming a standard consideration in contemporary residential design rather than an optional extra.

The Microgeneration Support Scheme, whilst still developing, promises to further incentivise solar adoption by enabling homeowners to sell surplus electricity back to the grid at favourable rates. This feed-in tariff arrangement transforms solar panels from purely cost-saving devices into potential income generators, fundamentally altering the economic calculus for prospective installers like MMK Solar.

  • Integration into New Build Construction

The most profound impact of solar technology is evident in new residential developments, where integrated design approaches enable optimal system performance and aesthetic coherence. Forward-thinking developers now incorporate solar considerations from the earliest planning stages, orienting properties to maximise southern exposure and designing roof profiles that accommodate panel installations without compromising architectural integrity.

This holistic approach extends beyond simple panel placement. Modern developments increasingly feature coordinated systems where solar generation interfaces seamlessly with battery storage, heat pumps, and intelligent home energy management systems. Such integration enables unprecedented levels of energy self-sufficiency, with some new Irish homes achieving 70% or greater independence from grid electricity during warmer months.

Building Information Modelling (BIM) technology has facilitated this integration, allowing architects and engineers to simulate solar performance during the design phase. These predictive capabilities enable optimisation of panel placement, system sizing, and electrical infrastructure before construction commences, reducing installation costs and maximising long-term performance. Consequently, solar systems in new builds typically deliver superior returns compared to retrofit installations, as the entire property ecosystem is designed around home renewable energy from inception.

  • Retrofit Applications in Existing Housing Stock

Whilst new builds benefit from integrated design, the majority of Ireland’s housing stock predates modern energy standards, presenting both challenges and opportunities for solar retrofitting. Older properties often feature suboptimal roof orientations, structural limitations, and outdated electrical systems that complicate solar installations. Nevertheless, technological advances and innovative installation techniques have made solar retrofitting increasingly viable across diverse property types.

Lightweight panel designs now enable installation on roofs previously deemed unsuitable due to load-bearing constraints, whilst micro-inverter technology allows systems to function efficiently despite shading or non-ideal orientations. For properties where traditional rooftop installations prove impractical, ground-mounted arrays and solar tiles offer alternative pathways to renewable generation.

The economics of retrofit installations have improved markedly, with typical payback periods now ranging from eight to twelve years depending on system size and household consumption patterns. When combined with available grants, many homeowners achieve energy cost reductions of 40-60%, providing compelling financial incentives alongside environmental benefits. This economic attractiveness has stimulated a thriving installation sector, with hundreds of certified installers now operating across Ireland.

  • Battery Storage and Energy Independence

The integration of battery storage systems represents perhaps the most transformative development in residential solar technology. Traditional grid-tied systems without storage can only utilise solar generation instantaneously, necessitating grid electricity during evenings and overnight periods when consumption typically peaks. Battery systems fundamentally alter this dynamic, enabling households to store surplus daytime generation for evening use, dramatically increasing solar self-consumption rates.

Modern lithium-ion battery systems offer storage capacities ranging from 5kWh to 15kWh or more, sufficient to power typical Irish homes through evening peak periods and overnight. Combined with adequately sized solar arrays, these systems can deliver energy independence rates exceeding 80% during spring and summer months, with meaningful contributions throughout winter.

Beyond economic benefits, battery storage enhances energy security, providing backup power during grid outages – an increasingly pertinent consideration given climate-related disruptions to electricity networks. This resilience aspect is particularly valued in rural areas where service restoration may require extended periods following severe weather events.

  • Environmental and Economic Impact

The cumulative environmental impact of Ireland’s residential solar revolution is substantial and growing. Each installed kilowatt of solar capacity reduces annual carbon emissions by approximately 0.5 tonnes, collectively preventing thousands of tonnes of greenhouse gases from entering the atmosphere annually. As installations multiply, this contribution towards Ireland’s climate obligations becomes increasingly significant, complementing larger-scale renewable projects like offshore wind farms.

From an economic perspective, widespread solar adoption reduces pressure on the national grid during peak demand periods, potentially deferring or eliminating the need for costly infrastructure upgrades. At the household level, solar installations provide hedge against future energy price volatility, offering predictable, low-cost electricity generation over system lifespans typically exceeding 25 years.

The solar sector itself has become a notable employer, with installation, maintenance, and related services supporting thousands of jobs nationwide. This growth in green employment aligns with broader economic development objectives whilst contributing to the low-carbon transition.

  • Challenges and Future Prospects

Despite remarkable progress, challenges remain. Grid infrastructure in some areas requires upgrading to accommodate high penetrations of distributed generation, whilst planning regulations in certain contexts can complicate installations, particularly in conservation areas or protected structures. Ensuring installer quality and consumer protection as the market expands requires ongoing regulatory attention.

Looking forward, continued technological advancement promises even greater possibilities. Emerging technologies including perovskite solar cells, bifacial panels, and building-integrated photovoltaics may deliver efficiency gains and aesthetic improvements that further accelerate adoption. As battery costs continue declining and vehicle-to-home technology matures, the integration of electric vehicles into home energy systems presents exciting possibilities for enhanced self-sufficiency.

  • Conclusion

Solar technology has unquestionably revolutionised residential construction in Ireland, transforming renewable energy from aspiration to mainstream reality. Through supportive policies, technological advancement, and growing environmental awareness, solar systems have become integral to modern Irish homes, delivering economic, environmental, and energy security benefits that extend far beyond individual households.

Certa expands to 25 HVO sites across Ireland

Certa, which is part of DCC plc, is expanding to 25 HVO fuel sites across Ireland as it responds to soaring demand from thousands of diesel drivers who are choosing the renewable fuel to reduce their carbon emissions while they hold back on switching to an electric vehicle (EV).

Hydrotreated Vegetable Oil (HVO) is produced from waste plant matter and can be used as a direct replacement for diesel without any need for engine modifications to help motorists lower their carbon emissions by up to 90%.

Demand for HVO is being driven by diesel drivers who want to ‘go green’ but who have put off switching to an electric vehicle (EV) for a variety of reasons, including the cost of buying an EV, the lack of charging infrastructure across the country, and not having their own driveway or off-street parking where they can install a home charger.

Certa is expanding its HVO offering at a rapid pace and its new HVO fuel site in Portlaoise, which opens to the public this week, is the 25th such site to open over the past 18 months across 17 counties, marking a significant milestone for the company and the fuel industry in Ireland.

Certa opened Ireland’s first fully fledged HVO fuel station in Liffey Valley in late 2023 at a cost of €1 million. 15 of the 25 HVO fuel sites that Certa currently operates have opened over the past eight months and the company has plans to open five more HVO fuel sites over the coming months.

Certa operates a total of 54 forecourt sites and is now the largest supplier of HVO to motorists across Ireland. Demand for the renewable fuel has also been helped by Certa’s decision to provide the new HVO pumps alongside its diesel and petrol pumps. The fuel is distinguished by a pink nozzle to stand out from the traditional black diesel and green petrol nozzles.

Orla Stevens, Managing Director, Certa Ireland said:

“Certa is delighted to open our 25th HVO fuel site in Portlaoise this week and to continue leading the way in making HVO more widely available to motorists across Ireland. Our goal is to make it easy for motorists to transition to HVO as a renewable alternative to diesel to help them to lower their carbon emissions.

‘Diesel and petrol cars accounts for 84% (2.14 million) of the cars on Irish roads. 17% of all   new cars sold in Ireland so far this year were diesel. Diesel drivers are holding off on making the switch to EV driving for a variety of reasons. HVO provides an alternative solution and diesel drivers are switching to this biofuel where it is available to them.

“The demand for HVO has grown as we have opened each new HVO fuel site across our network and our plan is to complete the upgrading of our entire network into next year as we continue our journey towards a net zero future.”

The Certa and Emo forecourts selling HVO include Liffey Valley, Finglas (Clearwater), Dundrum, Clarehall, Tallaght and Greenogue in Dublin; Lee Tunnel in Cork, Corofin in Clare, Letterkenny in Donegal, Ballinasloe in Galway, Maynooth in Kildare, Killarney in Kerry, Portlaoise in Laois, Moyne in Longford, Dundalk in Louth, Ballyhaunis in Mayo, Trim in Meath, Kilcormac in Offaly, Clonmel in Tipperary, Waterford city in Waterford, Athlone and Mullingar in Westmeath, and Castlebridge, Gorey and Wexford town in Wexford.

Tech sector emissions, energy use grow with rise of AI

Tech sector carbon emissions continued their rise in recent years, fueled by rapid advances in artificial intelligence (AI) and data infrastructure, according to Greening Digital Companies 2025.

The report, produced by the International Telecommunication Union (ITU) and the World Benchmarking Alliance (WBA), tracks the greenhouse gas (GHG) emissions, energy use, and climate commitments of 200 leading digital companies as of 2023, the most recent year for which full data is available.

While the annual report calls on digital companies to address their growing environmental footprint, it also indicates encouraging progress. Worldwide, more companies had set emissions targets, sourced renewable energy and aligned with science-based frameworks.

“Advances in digital innovation — especially AI — are driving up energy consumption and global emissions,” said ITU Secretary-General Doreen Bogdan-Martin. “While more must be done to shrink the tech sector’s footprint, the latest Greening Digital Companies report shows that industry understands the challenge — and that continued progress depends on sustaining momentum together.”

Global AI expansion fuels energy demand

According to the latest edition of the report, electricity consumption by data centers — which power AI development and deployment, among other uses — increased by 12 per cent each year from 2017 to 2023, four times faster than global electricity growth.

Four leading AI-focused companies alone saw their operational emissions increase in the reporting period by 150 per cent on average since 2020. This rise in energy that is either produced or purchased – known as Scope 1 and Scope 2 emissions – underscores the urgent need to manage AI’s environmental impact.

In total, the amount of greenhouse gas emissions reported by the 166 digital companies covered by the report contributed 0.8 per cent of all global energy-related emissions in 2023.

The 164 digital companies that reported electricity consumption accounted for 2.1 per cent of global electricity use, at 581 terawatt-hours (TWh), with 10 companies responsible for half of this total.

“Digital companies have the tools and influence to lead the global climate transition, but progress must be measured not only by ambition, but by credible action,” said Lourdes O. Montenegro, Director of Research and Digitisation at WBA. “This report provides a clear signal to the international community: more companies are stepping up, but emissions and electricity use continues to rise.”

Progress amid rising challenges

Although emissions continued their rise, Greening Digital Companies 2025 highlights steps taken by many tech firms that suggest a strengthening of transparency and accountability.

Eight companies scored above 90 per cent in the report’s climate commitment assessment on data disclosure, targets and performance. This is up from just three in last year’s report.

For the first time, the report includes data on companies’ progress toward meeting climate targets and realizing stated net-zero ambitions. Almost half of the companies assessed had committed to achieving net-zero emissions, with 41 firms targeting 2050 and 51 aiming for earlier deadlines.

Other trends among the 200 digital companies featured in the report include:

  • Renewable energy adoption: 23 companies operated on 100 per cent renewable energy in 2023, up from 16 in 2022.
  • Dedicated climate reporting: 49 companies released standalone climate reports, signaling greater transparency.
  • Scope 3 consideration: The number of companies publishing targets on indirect emissions from supply chains and product use rose from 73 to 110, showing increasing awareness of industry impacts.

A call for bold, collaborative and immediate action

Highlighting how the tech sector can ensure long-term digital sustainability, the joint ITU-WBA report recommends that companies:

  • Strengthen data verification, target ambition and climate reporting, including by publishing climate transition action plans.
  • Disclose the full environmental footprint of their AI operations.
  • Foster cross-sector collaboration among tech firms, energy producers and environmental advocates, alongside industry initiatives to drive accelerated digital decarbonization.
  • Keep accelerating renewable energy adoption.

“The Greening Digital Companies report has become a vital tool in tracking the climate footprint of the tech sector,” said Cosmas Luckyson Zavazava, Director of ITU’s Telecommunication Development Bureau. “Despite the progress made, greenhouse gas emissions continue to rise, confirming that that the need for digital companies to adopt science-aligned, transparent, and accountable climate strategies has never been greater. ITU’s work in monitoring the environmental impact of the sector is a crucial step towards achieving a sustainable digital transformation.”

ITU’s Telecommunication Development Bureau is working with regulators, statisticians, academics, and industry experts to define indicators that support national GHG monitoring and data-driven action through the Expert Group on Telecommunication/ICT Indicators.

As the COP30 UN climate conference approaches, ITU’s Green Digital Action aims to ensure that updated climate pledges and adaptation plans will fully reflect the complete impacts of digital technologies.
