The challenge: Sustainability-minded manufacturer on a journey to cut carbon emissions

Deceuninck design and manufacture highly energy efficient windows and doors from their UK headquarters and production facility in Calne, Wiltshire. In 2022, the business signed up to the Science Based Targets Initiative and have committed to cutting their Scope 1 and 2 carbon emissions by 60% by 2030, based on a 2021 baseline.

Committed to being part of the solution to climate change they opted to install a large solar array to provide most of their onsite energy usage. The local District Network Operator has an export limit of 500 kW to protect energy infrastructure, so Good Energy Solar worked alongside partner, Hark to install a certified G100 export limitation device to make the installation compliant.

The Solution: A 2,200 panel solar array, cutting carbon emissions by nearly 500 tonnes a year

As principal contractors, Good Energy Solar installed an impressive 2,200 solar panel array, with 1100 SolarEdge optimisers and 8 SolarEdge inverters.This substantial solar infrastructure delivers multiple benefits: from producing 895,762 kWh of clean energy each year which reduces their reliance on the grid and saves them a huge £158,000 in their annual bills, to slashing their annual CO2 emissions by an impressive 498.5 tonnes.

Not only does this reduce Deceuninck’s carbon emissions, their sustainably-produced windows and doors will cut carbon emissions for their customers too.

Following installation and a witness test, their export limitation device works seamlessly in the background to optimise energy production, consumption and avoid exceeding export limits.

Darren Woodcock, Operations Director for Deceuninck said: “We have every aspect of the roof that could be covered in panels, covered. The solar energy will help us offset rising energy costs, but will also generate huge environmental savings, further reducing our CO₂ emissions, and allowing fabricators to benefit from the saving.”

“This has been a very positive experience for us, the entire installation team are a great credit to Good Energy Solar, always professional and took the time to take us through each step of the process, regularly updating the installation along the way. We only experienced around four hours of operations downtime whilst the inverters were connected. It was a seamless installation.”
