Irish SMEs Lead Solar Surge: 34% Planning Adoption in 2026

Small and medium-sized enterprises across Ireland are emerging as the unexpected leaders of the country's energy transition, with solar power topping investment priorities according to a landmark new report released 8 June 2026.

The inaugural Flogas Sustainability Report, surveying 300 Irish business decision-makers, reveals that 34% of medium-sized businesses and 31% of small businesses are planning to adopt solar technology. Among medium-sized firms intending to make the transition, nearly half (46%) expect to install solar panels this year.

The findings challenge the long-held assumption that large corporates would lead Ireland's renewable energy shift. Instead, SMEs are taking decisive action now, driven by energy cost control, supply security and competitive advantage in an increasingly sustainability-conscious marketplace.

Why SMEs Are Going Solar Now

The report, conducted by iReach Insights on behalf of Flogas, identifies three primary drivers pushing Irish businesses toward solar adoption in 2026:

1. Energy Cost Control

With electricity prices remaining 70% higher than 2020 levels and ongoing global energy market volatility, businesses are seeking long-term cost certainty. Solar panels lock in generation costs at approximately €0.12 per kWh for 25 years, insulating businesses from future price spikes.

At current commercial electricity rates of €0.35 to €0.45 per kWh, solar offers immediate savings on daytime energy consumption, with typical payback periods of 4 to 6 years for commercial installations.

2. Energy Security

Recent geopolitical instability has exposed Ireland's dependence on imported energy (70% of primary energy is imported). Solar provides on-site generation that reduces reliance on grid electricity and protects businesses from supply disruptions.

John Rooney, Managing Director at Flogas, said: "Irish businesses are motivated and ready to act, particularly given the current uncertain outlook in energy markets, but they are consistently seeking practical, affordable pathways. They are asking, 'What is the first step?' and 'How do we make this work financially with tangible cost control?'"

3. Competitive Advantage

Sustainability credentials are increasingly important for winning contracts, attracting customers and meeting supply chain requirements. The report found that 92% of large businesses and 91% of medium-sized firms now consider sustainability important to their corporate strategy.

Ken O'Byrne, Commercial Director at Flogas, noted: "SMEs are under growing pressure from customers, supply chains and international partners. They want solutions that are commercially realistic, flexible and capable of delivering savings in the near term. That is why we are seeing such strong momentum behind solar."

The Business Case: Real-World Returns

Emerald Park provides a compelling example of solar ROI for Irish businesses. The park's solar installation, supported by Flogas, is projected to save over €30,000 annually in energy costs, with potential lifetime savings of up to €1 million and a payback period of approximately five years.

Charles Coyle, Managing Director of Emerald Park, said: "Our investment in solar panels is making sustainability not just a responsibility, but a smart business decision."

Typical Commercial Solar Returns in Ireland

At the time of writing, businesses can claim SEAI Non-Domestic Microgen Grants of up to €162,600 depending on system size, making commercial solar more accessible than ever.

Overcoming the Cost Barrier

Despite strong interest, the report identifies upfront cost as the biggest barrier to adoption, cited by 62% of respondents. However, innovative financing models are helping businesses overcome this hurdle.

Solar-as-a-Service Gains Traction

The report reveals that 72% of medium-sized companies are now considering Solar-as-a-Service models, which allow businesses to access solar energy without significant upfront capital investment.

Under this model:

• A third-party provider owns and maintains the solar system
• The business pays a fixed monthly fee or discounted rate for solar electricity generated
• No upfront capital expenditure required
• Immediate savings on electricity bills
• Maintenance and monitoring included

This approach is particularly attractive for SMEs with limited capital budgets or those who prefer to preserve cash flow for core business operations.

Traditional Purchase with SEAI Grant

For businesses able to invest upfront, purchasing a system outright with SEAI grant support typically delivers the best long-term returns:

Example: Medium-sized business (30 kWp system)

• Total cost: €75,000
• SEAI grant: €28,800
• Out-of-pocket cost: €46,200
• Annual savings: €11,000 (at €0.40/kWh average commercial rate)
• Payback: 4.2 years
• 25-year savings: €275,000 (assuming 3% annual electricity price increases)

Solar Displacing Gas and Cutting Emissions

The business case for solar extends beyond direct cost savings. Analysis by Baringa for Wind Energy Ireland found that solar generation displaced almost 188 million cubic metres of gas last year, avoiding energy and carbon costs worth €94 million nationwide.

For businesses facing carbon tax (currently €71 per tonne of CO₂, rising to €100 by 2030), solar offers triple benefits:

• Lower electricity bills
• Reduced carbon tax liability
• Improved sustainability credentials

SMEs Moving Faster Than Large Corporates

One of the most surprising findings in the Flogas report is that SMEs are outpacing large corporates in practical sustainability action.

Ken O'Byrne explained: "Traditionally, people assumed large corporates would move first on sustainability, but SMEs are increasingly the businesses taking practical action now. They are proving highly pragmatic and focused on solutions that deliver near-term savings and energy security benefits."

This agility advantage stems from:

• Shorter decision cycles: SMEs can approve investments in weeks rather than quarters
• Direct owner involvement: Business owners see immediate impact on bottom line
• Flexibility: Easier to adapt operations and integrate new technology
• Competitive pressure: Need to differentiate in crowded markets

Beyond Solar: Other Renewable Trends

While solar dominates SME renewable energy plans, the report also highlights growing interest in:

Corporate Power Purchase Agreements (CPPAs)

Once explained, 48% of retail and hospitality businesses said they would consider CPPAs for long-term price certainty. Pharmaceutical and manufacturing firms show even stronger interest, at 75%.

Renewable Electricity Tariffs

Businesses are switching to 100% renewable electricity supply as a quick first step before investing in on-site generation.

Biomethane

15% of large businesses already use renewable gas, with 26% of pharmaceutical and manufacturing companies planning or considering adoption.

What This Means for Irish Businesses

The Flogas report confirms that 2026 is a pivotal year for commercial solar adoption in Ireland. With strong grant support, proven ROI, innovative financing models and increasing competitive pressure, the business case has never been clearer.

Is Solar Right for Your Business?

Solar works particularly well for businesses with:

• High daytime electricity use (retail, offices, light manufacturing, hospitality)
• Suitable roof space (flat or pitched roofs with south, east or west orientation)
• Long-term occupancy (owned premises or long leases of 10+ years)
• Sustainability goals (supply chain requirements, customer expectations)

Typical commercial installations range from 10 kWp for small shops and offices to 100+ kWp for warehouses, factories and large retail premises.

Key Considerations Before Installing

• Energy consumption profile: Solar delivers best ROI when your peak consumption aligns with daylight hours
• Roof condition and capacity: Ensure your roof can support panel weight and has sufficient unshaded area
• Grid connection: Check with ESB Networks on connection requirements and export arrangements
• Planning permission: Most commercial solar installations under 50 kWp are exempt, but always verify with local planning authority
• Financing options: Compare outright purchase (with SEAI grant), leasing, and Solar-as-a-Service models
