Solar panels for warehouses in Richmond
The economics of a Richmond rooftop array turn on how much of the generation the occupier uses on site. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
910 kWh per kWp a year at this latitude, so a 500 kWp array models at about 455,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Greater London
What a roof in Richmond actually generates
Modelled irradiation at this latitude is 1169 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 910 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
Richmond ranks 8 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.
Send us the postcode
Tell us where the unit is and roughly how big the roof is. We come back with what it can carry, what it would generate against your consumption, and the three ways to pay for it.
Lenzie Consulting Ltd arranges the survey and passes your details to our MCS-certified installation partner so they can quote.
Questions about solar in Richmond
- How much does a warehouse roof in Richmond generate?
- The model gives 910 kWh for every kWp installed here, so 500 kWp comes out at about 455,000 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 Richmond have capacity?
- UK Power Networks is the distribution network operator for Greater London. 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.
