Is there enough sun in Sleaford to make this work?

Modelled at 898 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 449,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Who do we apply to for export in Sleaford?

Capacity varies street by street, and only National Grid Electricity Distribution can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.

Do we need planning permission in North Kesteven?

In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with North Kesteven first either way.

Has anyone near NG34 already done this?

The planning database records 6 solar schemes in this postcode district. 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.

Solar panels for warehouses in Sleaford

What makes a Sleaford scheme work is rarely the panels. It is the condition of the roof underneath them. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.

898 kWh per kWp a year at this latitude, so a 500 kWp array models at about 449,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Sleaford actually generates

Modelled irradiation at this latitude is 1145 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 898 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.

Surveys run across NG postcodes, NG34 outward.

North Kesteven is the planning authority for most sites here, and the built-up area holds a population of about 18,030, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

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

Jul produces 6.2 times what Dec does on the same roof. A 500 kWp array here models at about 449,000 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.

Sleaford ranks 3 of 8 towns we cover in Lincolnshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 861 to 906, a spread of 45 kWh per kWp. On a 500 kWp array that is about 22,500 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 National Grid Electricity Distribution

Connections around Sleaford are handled by National Grid Electricity Distribution, 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 Lincolnshire the planning database records 226 solar schemes totalling 7052 MW, of which 37 are operational (REPD Q1 2026).
