Rooftop solar array outperforming expectations
A rooftop solar array installed on a warehouse roof last year has generated around 7% more energy than initially forecast.

THE £235,000 project was initiated by corrugated packaging manufacturer GWP Packaging, part of Macfarlane Packaging, at its Cricklade site in Wiltshire as part of moves to increase both commercial and sustainable operation.
The 380kw capacity system, installed by leading solar PV and wind supplier, CleanEarth Energy, on two buildings at the company’s manufacturing site, has generated a combined 360 MWh of energy over the first 12 months – enough power to charge 3.6 million kettles. When it was installed it was expected to generate 40% of the company’s electricity requirement, just over 330 MWh annually.
The system has also saved the equivalent of 75 tonnes of CO2 emissions since its installation.
Macfarlane Packaging Head of Sustainability David Patton, said: “It’s great to see these figures and the difference the solar panels are making. We remain committed to using renewable energy wherever possible across our operations, with more solar panel installations planned over the coming years.”
