Case Study
Twinkl Educational Publishing, Sheffield
Commercial Solar PV Installations
Twinkl commissioned us to deliver two substantial roof mounted solar PV systems across their Sheffield head offices. The aim was to cut ongoing energy costs while supporting their long term sustainability plans.
By working closely with Twinkl’s facilities team, Homeco designed and installed systems tailored to each site. Both arrays now provide significant on site generation, reducing grid reliance and helping the company make measurable progress towards their environmental goals.
Eccelsall Road Office
System size 50kWp
Annual generation 41,650kWh
Estimated annual savings £11,500
Estimated payback Under three and a half years
CO2 reduction 447 tonnes over twenty five years
This project involved installing a fifty kilowatt peak system across the main office roof. With strong consumption during working hours, Twinkl is able to use most of the generated energy directly, accelerating the financial return and delivering a major cut in operational emissions.
Second Sheffield Office
System size 80kWp
Annual generation 66,640kWh
Estimated annual savings Up to £18,600
Estimated payback Under three and a half years
CO2 reduction 716 tonnes over twenty five years
The second installation, an eighty kilowatt peak system mounted on a slate roof, further boosts Twinkl’s onsite generation capacity. The array provides consistent output across the year and plays a central role in lowering energy spend across the wider site.
Together, these projects showcase how effective solar installations can support a growing organisation. Twinkl now benefits from reliable onsite energy, reduced operational costs, and a marked improvement in long term sustainability performance.
