How much does a warehouse roof in Filton generate?

The model gives 895 kWh for every kWp installed here, so 500 kWp comes out at about 448,000 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 Filton have capacity?

National Grid Electricity Distribution is the distribution network operator for Bristol. 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 Filton unit?

Usually permitted development covers it. We still put the question to Bristol, City of before design sign-off, and we tell you early if a full application is needed rather than discovering it late.

Has anyone near BS34 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.

Solar panels for warehouses in Filton

What makes a Filton scheme work is rarely the panels. It is the condition of the roof underneath them. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

895 kWh per kWp a year at this latitude, so a 500 kWp array models at about 448,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Filton actually generates

Modelled irradiation at this latitude is 1147 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 895 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 BS postcodes, BS34 outward.

Bristol, City of is the planning authority for most sites here, and the built-up area holds a population of about 10,960, 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 Filton roof makes, month by month

Jul produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 448,000 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.

Filton ranks 5 of 5 towns we cover in Bristol on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 895 to 908, a spread of 13 kWh per kWp. Within Bristol that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

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 Filton 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.
