Solar panels for warehouses in High Wycombe
A High Wycombe warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. 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.
892 kWh per kWp a year at this latitude, so a 500 kWp array models at about 446,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in High Wycombe actually generates
Modelled irradiation at this latitude is 1145 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 892 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.
Distribution stock around High Wycombe clusters on M40 J4, A40 and A404, which is where the large single-let roofs are.
Surveys run across HP postcodes, HP13 outward.
Buckinghamshire is the planning authority for most sites here, and the built-up area holds a population of about 83,535, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
High Wycombe ranks 3 of 8 towns we cover in Buckinghamshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 881 to 904, a spread of 23 kWh per kWp. Within Buckinghamshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through Scottish and Southern Electricity Networks
Scottish and Southern Electricity Networks is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Buckinghamshire the planning database records 127 solar schemes totalling 955 MW, of which 21 are operational (REPD Q1 2026).

Questions about solar in High Wycombe
- What would a 500 kWp array produce in High Wycombe?
- Yes, and the number matters more than the sunshine. At 892 kWh per kWp a year, a 500 kWp array on a High Wycombe roof models at around 446,000 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 High Wycombe?
- Applications go to Scottish and Southern Electricity Networks, who run the network across Buckinghamshire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Buckinghamshire require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Buckinghamshire before the design is finalised.
