Solar panels for farms in Oldham
The case for solar on a Oldham holding turns on how much of the output the farm uses itself, not on how much the roof makes. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
771 kWh per kWp a year at this latitude, so a 500 kWp array models at about 386,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Greater Manchester
What a farm roof near Oldham generates
Modelled irradiation at this latitude is 987 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 771 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 13 percent below the mean across the areas we cover, so the case here rests on using the output on the holding rather than exporting it.
No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.
Surveys run across OL postcodes, OL4 outward.
Oldham is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
Oldham ranks 9 of 10 towns we cover in Greater Manchester on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 769 to 828, a spread of 59 kWh per kWp. On a 500 kWp array that is about 29,500 kWh a year between the strongest and weakest town in the county.
Grid connection through Electricity North West
Electricity North West operates the distribution network across Greater Manchester, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Greater Manchester the planning database records 118 solar schemes totalling 110 MW, of which 11 are operational (REPD Q1 2026).

Questions about solar in Oldham
- What would a 500 kWp array produce on a farm near Oldham?
- Yes, and the figure matters more than the sunshine. At 771 kWh per kWp a year, a 500 kWp array on a Oldham holding models at around 386,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Oldham?
- Applications go to Electricity North West, who run the network across Greater Manchester. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Oldham require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Oldham before the design is finalised.
