Solar panels for farms in Grays
Farm buildings around Grays carry broad, shallow roofs that were put up for storage and stock, not for generation. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.
927 kWh per kWp a year at this latitude, so a 500 kWp array models at about 464,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Essex
What a farm roof near Grays generates
Modelled irradiation at this latitude is 1190 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 927 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 areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Grays is higher than the record shows.
Most of the buildings we look at here sit in the RM postcode area.
Thurrock is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
Grays ranks 8 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 Grays
- What would a 500 kWp array produce on a farm near Grays?
- Yes, and the figure matters more than the sunshine. At 927 kWh per kWp a year, a 500 kWp array on a Grays holding models at around 464,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Grays?
- Applications go to UK Power Networks, who run the network across Essex. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Thurrock require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Thurrock before the design is finalised.
