Solar panels for warehouses in March
A March 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.

What a roof in March actually generates
Modelled irradiation at this latitude is 1154 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 900 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 PE postcodes, PE15 outward.
Fenland is the planning authority for most sites here, and the built-up area holds a population of about 21,345, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
March ranks 6 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through UK Power Networks
Connections around March 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.
Across Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in March
- Is there enough sun in March to make this work?
- Modelled at 900 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 450,000 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 March?
- 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.
- Do we need planning permission in Fenland?
- 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 Fenland first either way.
- Has anyone near PE15 already done this?
- The planning database records 6 solar schemes in this postcode district, 1 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
