Solar panels for farms in Altrincham
The case for solar on a Altrincham 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.
816 kWh per kWp a year at this latitude, so a 500 kWp array models at about 408,000 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 Altrincham generates
Modelled irradiation at this latitude is 1046 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 816 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 8 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.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Altrincham is higher than the record shows.
Surveys run across WA postcodes, WA14 outward.
Manchester 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.
Altrincham ranks 2 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 Altrincham
- Is there enough sun around Altrincham to make this work?
- Modelled at 816 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 408,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Altrincham?
- Only Electricity North West can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
- Do we need planning permission in Manchester?
- In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Manchester either way.
