Solar panels for warehouses in Andover

A Andover warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.

What a roof in Andover actually 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 towns we cover, which is as good as UK rooftop gets outside the south coast.

Distribution stock around Andover clusters on A303 and A34, which is where the large single-let roofs are.

Surveys run across SP postcodes, SP10 outward.

Test Valley is the planning authority for most sites here, and the built-up area holds a population of about 48,480, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

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 warehouse 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).

Questions about solar in Andover

How much does a warehouse roof in 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 any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Does the grid around Andover have capacity?
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. We submit it as part of the design.
Is planning permission needed for panels on a Andover unit?
Usually permitted development covers it. We still put the question to Test Valley before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
Has anyone near SP10 already done this?
The planning database records 6 solar schemes in this postcode district, 6 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
