Solar panels for farms in Retford
Most holdings around Retford already own the best generating site they will ever have, and it is the roof of the shed they built for something else. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
869 kWh per kWp a year at this latitude, so a 500 kWp array models at about 435,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Nottinghamshire
What a farm roof near Retford generates
Modelled irradiation at this latitude is 1111 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 869 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
The planning record lists 5 ground mounted solar schemes in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 4 MW, with the largest at 49.9 MW. Source: Renewable Energy Planning Database, Q1 2026.
Surveys run across DN postcodes, DN22 outward.
Bassetlaw 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.
Retford ranks 2 of 7 towns we cover in Nottinghamshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 842 to 874, a spread of 32 kWh per kWp. Within Nottinghamshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Nottinghamshire the planning database records 164 solar schemes totalling 3700 MW, of which 35 are operational (REPD Q1 2026).

Questions about solar in Retford
- How much does a farm roof near Retford generate?
- The model gives 869 kWh for every kWp installed here, so 500 kWp comes out at about 435,000 kWh a year before shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Will the rural network around Retford take the export?
- National Grid Electricity Distribution is the distribution network operator for Nottinghamshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. Rural supplies are often the binding constraint, so we ask the question before an array is sized.
- Is planning permission needed for panels on a farm building near Retford?
- Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Bassetlaw before design sign-off.
- Has anyone near DN22 already done this?
- The planning database records 5 ground mounted and 0 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.
