How much does a farm roof near Andover generate?

The model gives 915 kWh for every kWp installed here, so 500 kWp comes out at about 458,000 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 Andover take the export?

Scottish and Southern Electricity Networks is the distribution network operator for Hampshire. 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 Andover?

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 Test Valley before design sign-off.

Has anyone near SP10 already done this?

The planning database records 0 ground mounted and 6 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.

Solar panels for farms in Andover

Farm buildings around Andover carry broad, shallow roofs that were put up for storage and stock, not for generation. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.

915 kWh per kWp a year at this latitude, so a 500 kWp array models at about 458,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Andover generates

Modelled irradiation at this latitude is 1172 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 915 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 3 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

6 roof mounted schemes are on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Andover is higher than the record shows.

Surveys run across SP postcodes, SP10 outward.

Test Valley 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.

FIG. 1 What a Andover roof makes, month by month

Jun produces 5.7 times what Dec does on the same roof. A 500 kWp array here models at about 458,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Andover ranks 6 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.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through Scottish and Southern Electricity Networks

Connections around Andover are handled by Scottish and Southern Electricity Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a farm uses most of what the roof makes during the working day.

Across Hampshire the planning database records 237 solar schemes totalling 1634 MW, of which 51 are operational (REPD Q1 2026).
