The Background & Operational Challenge
Instarmac Group plc is a multi-award-winning, market-leading specialist in the research, development, and production of high-specification materials for highway maintenance, urban regeneration, commercial tiling, and flooring sectors. Operating extensive manufacturing and processing facilities, the business demands high daily energy consumption to power its production lines and distribution hubs.
With volatile energy costs and ambitious sustainability targets across their operations, Instarmac sought an industrial-grade energy solution to reduce utility expenses, lower carbon emissions, and increase energy independence without disrupting ongoing manufacturing operations.
The Engineering & Solar PV Solution
Working alongside specialist delivery partners, PES UK specified and engineered a bespoke 768kWp commercial roof-mounted solar PV system tailored specifically to match Instarmac’s baseline power requirements.
The system was designed to maximize daytime solar harvest, feeding clean energy directly into the site’s main distribution networks. High-efficiency tier-1 solar panels and commercial-grade inverters were deployed alongside robust mounting systems to withstand long-term operational exposure while adhering to strict structural safety standards.
Results, Performance & Environmental Impact
In its first 12 months of operation, the 768kWp solar array met all key generation targets, producing over 667,000 kWh of zero-carbon power directly on site. Key project results include:
- £125,518 First-Year Savings: Direct, immediate reduction in daytime grid electricity charges.
- 4-Year Payback Period: Rapid ROI with years of localised, low-cost power generation remaining on system lifespan.
- Carbon Offset: Significant decrease in Scope 2 emissions, strengthening Instarmac’s corporate environmental commitments.
- Tariff Protection: Greater independence from grid volatility and future power price spikes.
