Is there enough sun around Tower Hamlets to make this work?

Modelled at 976 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 488,000 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 Tower Hamlets?

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.

Solar panels for farms in Tower Hamlets

Farm buildings around Tower Hamlets 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.

What a farm roof near Tower Hamlets generates

Modelled irradiation at this latitude is 1247 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 976 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 10 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

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 Tower Hamlets roof makes, month by month

Jun produces 6.3 times what Dec does on the same roof. A 500 kWp array here models at about 488,000 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.

Tower Hamlets ranks 2 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

Connections around Tower Hamlets are handled by UK Power Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a farm uses most of what the roof makes during the working day.
