Commercial solar in Diss - FAQs

Does Padley's Poultry's Scope-3 framework flow to IP22 suppliers?

Yes - Padley's supplies major UK retailers whose SBTi-aligned Scope-3 requirements cascade to tier-2 poultry-processing, packaging and refrigeration suppliers around Sawmills Industrial Estate. On-site PV with G99 acceptance and export limitation is one of the few directly-evidenced Scope-1/2 levers within those scorecards.

Is south-Norfolk irradiance strong for commercial PV?

Yes - IP22 delivers around 1,000–1,040 kWh per kWp per year, in the higher East Anglia irradiance band, and poultry-processing and cold-storage load profiles (sustained refrigeration, packaging) drive self-consumption into the 80s of percent on well-sized rooftop arrays.

How does UK Power Networks handle IP22 G99?

Sub-500 kWp G99 with export limitation typically clears in 8–10 weeks on Sawmills Industrial Estate and Vinces Road feeders, and 1 MWp is deliverable subject to network study on the Diss 33 kV.

Are Waveney Valley rural sites at flood-plain risk that affects PV design?

The immediate River Waveney corridor (Environment Agency Flood Zone 3) affects a narrow ribbon south of the town - Sawmills Industrial Estate sits at Zone 1 (low risk) and standard rooftop PV designs apply. Any equipment room or ground-level inverter positioning within Flood Zone 2 is elevated on plinth mounting as default.

How wide is Diss coverage?

Roydon, Palgrave, Scole, Eye, Harleston, Bressingham and Hoxne are day-one visits; Bury St Edmunds, Stowmarket, Norwich, Halesworth and Thetford are on planned survey days from the south-Norfolk base.
