Solar panels for warehouses in Walthamstow
Sheds around Walthamstow tend to have more roof than the business has any other use for. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.
898 kWh per kWp a year at this latitude, so a 500 kWp array models at about 449,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Walthamstow actually generates
Modelled irradiation at this latitude is 1158 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 898 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.
Walthamstow ranks 48 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.

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 Walthamstow
- Is there enough sun in Walthamstow to make this work?
- Modelled at 898 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 449,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Walthamstow?
- Capacity varies street by street, and only UK Power Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
