O'Reilly's Cuts 19.85 Tonnes of CO₂ & Saves €375K with 59.76 kWp Solar

O’Reilly’s Wholesale, a cornerstone of Ireland’s FMCG distribution sector since 1959, has long built its success on reliability and forward-thinking. As a third-generation family business, they are now championing a new era of corporate responsibility by investing in renewable energy, ensuring their legacy includes a powerful commitment to environmental sustainability.

Project Overview

In 2024, O’Reilly’s Wholesale partnered with MarVal Power to install a 59.76 kWp rooftop solar PV system at their main distribution hub. The project features 144 high-efficiency solar panels, strategically positioned to power their extensive logistics and warehousing operations with clean energy.

Project Background

With a large-scale warehouse and a fleet of over 20 delivery vehicles, energy is a significant operational cost for O’Reilly’s Wholesale. The company’s leadership sought to proactively manage rising energy prices and reduce their environmental impact. The move to solar was driven by a strategic goal to enhance operational efficiency, secure long-term energy savings, and demonstrate a tangible commitment to sustainable business practices for their customers and community.

Solution Delivered

MarVal Power delivered a custom-designed solar PV solution engineered for the high-demand environment of a major distribution centre. Our analysis focused on matching the system’s generation curve with the facility’s peak daytime energy usage. The 144 Tier-1 panels were installed to maximise solar exposure, providing a consistent and reliable power source to run lighting, refrigeration, and administrative systems, thereby reducing reliance on the grid during core business hours.
