Solar panels for farms in Eastleigh
Farm buildings around Eastleigh carry broad, shallow roofs that were put up for storage and stock, not for generation. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.
942 kWh per kWp a year at this latitude, so a 500 kWp array models at about 471,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Hampshire
What a farm roof near Eastleigh generates
Modelled irradiation at this latitude is 1209 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 942 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 6 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
The planning record lists 1 ground mounted solar scheme 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 27 MW. Source: Renewable Energy Planning Database, Q1 2026.
Most of the buildings we look at here sit in the SO postcode area.
Eastleigh 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.
Eastleigh ranks 4 of 10 towns we cover in Hampshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 903 to 987, a spread of 84 kWh per kWp. On a 500 kWp array that is about 42,000 kWh a year between the strongest and weakest town in the county.

Grid connection through Scottish and Southern Electricity Networks
Scottish and Southern Electricity Networks operates the distribution network across Hampshire, 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 Hampshire the planning database records 237 solar schemes totalling 1634 MW, of which 51 are operational (REPD Q1 2026).

Questions about solar in Eastleigh
- Is there enough sun around Eastleigh to make this work?
- Modelled at 942 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 471,000 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 Eastleigh?
- Only Scottish and Southern Electricity Networks 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 Eastleigh?
- 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 Eastleigh either way.
