Another major renewable energy project has been successfully delivered. We’re proud to announce the completion of a 787.11kW Solar PV system for our valued client, Booker Group / METRO / Makro. This installation helps Makro work towards its ambitious sustainability goals and significantly reduces energy costs. But what led Makro to embrace solar power, and how did we at Hawley Building Services (HBS MEP) deliver a tailored solution? Below, we’ll explore the positive outcomes of this project and highlight why solar PV is such a compelling option for large-scale facilities.
Why Sustainability Matters
Businesses across wholesale and retail are increasingly recognising that sustainability is more than just a buzzword. Environmental commitments, government targets and the expectations of environmentally conscious customers all play a part in prompting companies like Makro to invest in renewable energy.
Energy consumption in large wholesalers can be substantial. Between extended lighting hours and extensive refrigeration, operational costs often run high. By integrating on-site renewable generation, sites like Makro can reduce their reliance on the grid, stabilise long-term costs and make a clear statement about their environmental priorities.

Controlling Energy Costs
Wholesale and retail facilities are sensitive to fluctuations in energy prices, and such volatility can affect overall profitability, especially when margins are already tight. A well-designed Solar PV system offers a measure of energy independence, enabling businesses to produce their own electricity during daylight hours. This reduces exposure to utility price increases and can significantly lower monthly bills over time.

Minimising Disruption During Installation
One key objective in delivering a project of this scale is ensuring minimal disruption to everyday operations. Makro’s busy environment, with regular customer visits and staff routines, meant careful planning was essential. We collaborated closely with the client to coordinate installation work, schedule quieter periods for any potentially intrusive tasks and maintain rigorous health and safety measures. Thanks to this planning, the installation progressed smoothly and safely without affecting Makro’s trading activities.

Designing the 787.11kW Solar PV System
Our team at HBS MEP began with a thorough site survey, evaluating factors such as roof condition, load-bearing capacity and potential shading. We then tailored a design that maximised energy capture while considering Makro’s typical electricity usage. Key aspects included:
- High-Efficiency Panels
Chosen for reliable performance in varied UK weather conditions. - Optimal Orientation
Angled to harvest the most sunlight throughout the year, helping maintain strong generation levels in all seasons. - Quality Inverters
Converting the direct current (DC) from the panels into alternating current (AC), ready for use throughout the facility. - Secure Mounting Systems
Ensuring the panels stay firmly in place, offering resilience against changing weather. and providing industry leading watertight warranties.
A forward-thinking approach also accommodates potential future expansions. Should Makro’s sustainability targets evolve further.
Seamless Integration with Existing Infrastructure
Because retailers can rely heavily on refrigeration, HVAC and other electrical systems, integrating the new Solar PV array required precise coordination. Our installation ensures that solar-generated electricity is distributed efficiently, with the option to incorporate energy storage technologies at a later date if desired.
We also set up a real-time monitoring system so the team can track performance and quickly address any anomalies. To find out more about how we handle end-to-end solutions, take a look at our About Us page, where you can see our ethos and approach.
Ongoing Support and Training
Long after the panels are fitted, a robust support structure is vital to maintain optimal performance. We provide training for facility managers so they can interpret monitoring data, schedule panel cleaning and identify any early signs of reduced efficiency. Our aftercare service remains available for additional guidance, system expansions or any future changes in our clients energy objectives.
Positive Outcomes for Makro and the Environment
Substantial Carbon Savings
By generating clean electricity, Makro reduces reliance on grid-based power, leading to a significant cut in carbon emissions. This aligns perfectly with its sustainability goals and resonates with both customers and partners who value responsible business practices.

Reduced Operating Costs
One of the most immediate advantages is the noticeable decrease in energy expenditure. Over the lifetime of the solar installation, Makro stands to make considerable savings, freeing up resources that can be reinvested into other facets of the business.
Stronger Brand Reputation
Companies that demonstrate tangible commitments to reducing their environmental impact often enjoy enhanced credibility in the marketplace. For Makro, adopting Solar PV further supports its role as a responsible and forward-looking business within the Booker Group. This positive public image can, in turn, attract new customers and strengthen relationships with existing ones.
Greater Operational Resilience
While solar energy alone does not guarantee full grid independence, every kilowatt generated on-site provides an extra layer of security. During peak demand periods, solar power can help balance overall consumption and reduce the likelihood of straining grid capacity.
