Solar panels for warehouses in Braintree
What makes a Braintree 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.
932 kWh per kWp a year at this latitude, so a 500 kWp array models at about 466,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Braintree actually generates
Modelled irradiation at this latitude is 1191 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 932 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 Braintree clusters on A120 and A131, which is where the large single-let roofs are.
Surveys run across CM postcodes, CM7 outward.
Braintree is the planning authority for most sites here, and the built-up area holds a population of about 43,190, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Braintree ranks 6 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.

| Scheme | Operator | Capacity | Mounting | Status |
|---|---|---|---|---|
| Land west of Hawkspur Green (Hill Hall Solar) | Lightsource Renewable Energy | 4.9 MW | Ground | Operational |
| Four Elms Solar Array | F H Nash Limited | 0.17 MW | Ground | Operational |
| Four Elms, Bardfield Road - Solar Array | F H Nash Limited | 0.35 MW | Ground | Awaiting Construction |
| Antislip Antiwear Treads International, Swinbourne Drive - Solar Panels | AATI Limited | 0.15 MW | Roof | Awaiting Construction |
Grid connection through UK Power Networks
UK Power Networks operates the distribution network across Essex, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Essex the planning database records 221 solar schemes totalling 2787 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in Braintree
- How much does a warehouse roof in Braintree generate?
- The model gives 932 kWh for every kWp installed here, so 500 kWp comes out at about 466,000 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 Braintree have capacity?
- UK Power Networks is the distribution network operator for Essex. 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 Braintree unit?
- Usually permitted development covers it. We still put the question to Braintree before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near CM7 already done this?
- The planning database records 4 solar schemes in this postcode district, 1 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.
