Real Sustainability Impact

This is more than just a technical upgrade—it’s an environmental game-changer. Our solar PV system is projected to generate 211.5 MWh of electricity annually, offsetting approximately 40.9 tonnes of CO₂ emissions every year. That’s the carbon-saving equivalent of planting 1,879 trees annually.

Self-consumption is forecasted at 81%, meaning the majority of generated energy is used on-site, reducing dependency on grid electricity and stabilising long-term energy usage. Any surplus power—estimated at 40.65 MWh annually—is exported back to the grid, further supporting the UK’s renewable energy mix.

The Economic Rationale: Greener and Smarter

Beyond its environmental benefits, this investment makes clear operational sense. With a payback period of just 3.5 years and a projected internal rate of return (IRR) of 30.19%, the system not only helps future-proof the site but also improves our long-term energy security.

Annual savings on electricity begin immediately, and cumulative energy savings grow substantially year after year. This positions the project as both a strategic and sustainable move for our business.

Technical Excellence Meets Future Readiness

Our choice of JA Solar n-type bifacial double glass modules—part of the DeepBlue 4.0 series—was deliberate. These high-performance panels feature superior temperature coefficients, excellent low irradiance response, and a 30-year linear power output warranty, providing long-term reliability even in challenging UK weather conditions.


The system’s smart inverter technology and real-time monitoring capabilities ensure optimal system performance, proactive maintenance, and long-term asset protection.

A Broader Commitment to Sustainability

This solar initiative is not a standalone action—it aligns with Ruia Group’s broader sustainability strategy. Already, 80% of our cotton is sourced as Better Cotton, and we are certified under ISO 14001 for Environmental Management. With these latest steps, we’re advancing our decarbonisation pathway, embracing circularity, and integrating renewable energy into our operations at scale.

A Beacon for the Industry

Transforming a 19th-century mill into a 21st-century green powerhouse is more than symbolic—it’s a testament to what’s possible when heritage and innovation come together. Our installation serves as a case study for how legacy infrastructure can be future-proofed without compromise.

We hope our journey inspires others in the textiles and manufacturing sectors to take bold steps. Sustainability is not just a marketing buzzword—it’s a shared responsibility. By investing in clean energy, we reduce our carbon footprint, protect our business from energy volatility, and contribute to the UK’s net zero goals.

At Richard Haworth, our legacy has always been about quality, innovation, and responsibility. By adding solar power to Kearsley Mill, we’re not only enhancing operational efficiency but also reinforcing our values. This project is a physical manifestation of our belief that environmental stewardship and industrial progress can go hand in hand.
