F. Duerr & Sons, the Manchester-based food manufacturer known for marmalade and peanut butter, has switched on 2,424 solar panels across two production sites. The system covers the Dallimore and Floats Road sites and is expected to supply about 22% of the company's annual electricity. The project also included removing and replacing an asbestos roof, which prepared the buildings for the panels. Early data from the Dallimore site shows solar covering around 25% of power use during a sunny July and August, with 18.66 tonnes of CO2e saved so far. Duerr's estimates the full installation will cut around 149 tonnes of CO2e per year. The company already buys 100% renewable electricity since 2019, so the panels reduce its reliance on grid power and feed into its SBTi-validated emissions targets.

Food plant puts 2,424 panels on two roofs and expects about 22% of annual electricity from them. That is a solid share for an industrial site. The 149 tCO2e annual saving is not huge, but it is real and it counts toward an SBTi target. The asbestos roof replacement was probably the bigger cost, so bundling it with solar makes sense.

The notable part is they already buy 100% renewable power since 2019. On-site solar is not about claiming green electricity, it is about cutting how much grid power they pull and locking in a bit of price stability. Early numbers show 18.66 tCO2e saved since July, which is small against a factory footprint, but the installation is still ramping up.

Would like to know the basis for that 22% average. Summer generation is strong, but winter output drops hard and a food plant runs year-round. No storage mentioned, so the self-consumption ratio and export arrangement will shape the real economics. Still, two sites with 2,424 panels and a new roof is a proper physical project, not a press release.

The carbon accounting is loose. 18.66 tCO2e saved depends on grid carbon intensity at the time of generation, and whether they use location-based or market-based accounting. Since they already buy renewable electricity, the additionality is physical generation, not new certificates. The SBTi framing only matters if the project is counted under the right scope and boundary.

Right sequence: replace the asbestos roof, then put panels on top. Doing solar on an old roof would have meant pulling it all off later. What the article leaves out is cost, payback, and maintenance. For a family-owned manufacturer, those numbers decide if the other sites follow. Also worth asking whether the new roof improved insulation, since that changes the heating and cooling load.

Good example of on-site generation for an industrial load. 2,424 panels across two sites, roughly 22% of annual electricity, paired with a roof replacement that had to happen anyway. Absolute carbon savings are modest, but this is the kind of project that adds up across manufacturing.
