Powering Solar Data Centre Fit-Out Provider with a Low Cost Commercial Solar Project in Ireland

Modubuild, one of Ireland’s leading Cleanroom and Data Centre Fit-Out Solutions Providers, completed a solar data centre installation at its Co. Kilkenny facility to improve energy efficiency and reduce operating costs, all without disrupting daily operations.

Working in a sector where precision, compliance, and reliability are essential, our client required a solution that met strict quality standards while delivering measurable commercial value. A Commercial Solar PV system designed for data centre operations proved to be the ideal fit, offsetting a significant portion of energy demand in a facility with consistently high daytime electricity usage.

 

Objectives

  • Reduce long-term electricity overheads
  • Take advantage of SEAI grant and ACA tax benefits
  • Improve ESG performance in line with client expectations
  • Avoid any disruption to ongoing design, prefabrication, or admin operations

 

Solution

SOLARspan delivered a fully bespoke 72-panel commercial PV system, designed to maximise solar yield within available roof space and the client’s consumption profile. Installation was completed in just three days with zero downtime and no interference to ongoing operations.

The system went live immediately and began generating clean, low-cost electricity to power design and admin facilities during peak hours.

 

Results

  • Annual Energy Savings: €7,000 – €9,000
  • Payback Period: 2 Years & 7 months
  • Operational Disruption: 0%
  • Grant Support: SEAI Non-Domestic Microgen Grant €8,800
  • Tax Benefit: Accelerated Capital Allowance claimed in Year 1
  • Annual Energy From Solar: 69%

 

Why Solar Works for Data Centre and Cleanroom Fit-Out Providers in Ireland

Facilities supporting data centres and cleanroom environments typically have consistent daytime electricity demand, making commercial solar PV a strong match. For Irish businesses operating in compliance-driven sectors, solar can provide predictable energy savings while strengthening ESG reporting and tender competitiveness. By generating electricity on site, businesses reduce exposure to grid price volatility and support sustainability expectations from clients in life sciences, pharmaceuticals, and mission-critical infrastructure projects.

 

Looking Ahead

By generating its own electricity, Modubuild has increased energy independence while reducing exposure to future grid price increases. The installation also contributes to broader sustainability goals and provides a measurable asset when tendering for major data centre and life sciences projects.

 

“This was a smart investment in our future. SOLARspan’s team worked around us, delivered on time, and gave us a solution that supports both our cost base and our sustainability targets.”
