Solar panels for farms in Notting Hill

Around Notting Hill the constraint is rarely the roof. It is the incoming supply and what the network will accept back. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.

906 kWh per kWp a year at this latitude, so a 500 kWp array models at about 453,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Notting Hill generates

Modelled irradiation at this latitude is 1164 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 906 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 areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.

No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.

Jul produces 5.7 times what Dec does on the same roof. A 500 kWp array here models at about 453,000 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.

Notting Hill ranks 19 of 50 towns we cover in Greater London on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 847 to 987, a spread of 140 kWh per kWp. On a 500 kWp array that is about 70,000 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 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.

Questions about solar in Notting Hill

Is there enough sun around Notting Hill to make this work?
Modelled at 906 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 453,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Who do we apply to for export near Notting Hill?
Only UK Power Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
