Solar panels for warehouses in Merton
Roof space is the one asset a Merton unit already owns and rarely uses. 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.
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.

Warehouse rooftop solar across Greater London
What a roof in Merton actually generates
Modelled irradiation at this latitude is 1159 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
Merton ranks 39 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 Merton 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 warehouse uses most of what the roof makes during the working day.

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 Merton
- What would a 500 kWp array produce in Merton?
- Yes, and the number matters more than the sunshine. At 902 kWh per kWp a year, a 500 kWp array on a Merton roof models at around 451,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection in Merton?
- Applications go to UK Power Networks, who run the network across Greater London. They decide the export limit, and we handle the G99 paperwork alongside the array design.
