Solar panels for warehouses in Chesham
A Chesham 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.
891 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 Chesham actually generates
Modelled irradiation at this latitude is 1142 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 891 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.
Surveys run across HP postcodes, HP5 outward.
Buckinghamshire is the planning authority for most sites here, and the built-up area holds a population of about 23,695, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Chesham ranks 5 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
Connections around Chesham are handled by Scottish and Southern Electricity 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.
Across Buckinghamshire the planning database records 127 solar schemes totalling 955 MW, of which 21 are operational (REPD Q1 2026).

Questions about solar in Chesham
- Is there enough sun in Chesham to make this work?
- Modelled at 891 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 446,000 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 Chesham?
- Capacity varies street by street, and only Scottish and Southern Electricity 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.
- Do we need planning permission in Buckinghamshire?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Buckinghamshire first either way.
