What would a 500 kWp array produce on a farm near Marylebone?

Yes, and the figure matters more than the sunshine. At 902 kWh per kWp a year, a 500 kWp array on a Marylebone holding models at around 451,000 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 Marylebone?

Applications go to UK Power Networks, who run the network across Greater London. 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.

Solar panels for farms in Marylebone

A Marylebone farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.

902 kWh per kWp a year at this latitude, so a 500 kWp array models at about 451,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Marylebone generates

Modelled irradiation at this latitude is 1160 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 902 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.

FIG. 1 What a Marylebone roof makes, month by month

Jun produces 5.6 times what Dec does on the same roof. A 500 kWp array here models at about 451,000 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.

Marylebone ranks 37 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.

Grid connection through UK Power Networks

UK Power Networks operates the distribution network across Greater London, 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.
