Solar panels for warehouses in Basildon

Most of the industrial stock around Basildon carries a large, shallow-pitched roof that was never asked to do anything. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.

933 kWh per kWp a year at this latitude, so a 500 kWp array models at about 467,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Basildon actually generates

Modelled irradiation at this latitude is 1197 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 933 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 5 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

Distribution stock around Basildon clusters on A127, A13 and A130, which is where the large single-let roofs are.

We survey across the SS postcode area, starting from SS15.

Basildon is the planning authority for most sites here, and the built-up area holds a population of about 115,955, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).

Jun produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 467,000 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.

Basildon ranks 5 of 10 towns we cover in Essex on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 908 to 973, a spread of 65 kWh per kWp. On a 500 kWp array that is about 32,500 kWh a year between the strongest and weakest town in the county.

Grid connection through UK Power Networks

UK Power Networks is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across Essex the planning database records 221 solar schemes totalling 2787 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in Basildon

What would a 500 kWp array produce in Basildon?
Yes, and the number matters more than the sunshine. At 933 kWh per kWp a year, a 500 kWp array on a Basildon roof models at around 467,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Which network operator handles the connection in Basildon?
Applications go to UK Power Networks, who run the network across Essex. They decide the export limit, and we handle the G99 paperwork alongside the array design.
What does Basildon require for rooftop solar?
Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Basildon before the design is finalised.
