Solar panels for warehouses in Newmarket
The economics of a Newmarket rooftop array turn on how much of the generation the occupier uses on site. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
905 kWh per kWp a year at this latitude, so a 500 kWp array models at about 453,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Suffolk
What a roof in Newmarket actually generates
Modelled irradiation at this latitude is 1157 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 905 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.
Most of the units we look at here sit in the CB postcode area.
East Cambridgeshire is the planning authority for most sites here, and the built-up area holds a population of about 18,855, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Newmarket ranks 8 of 8 towns we cover in Suffolk on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 905 to 956, a spread of 51 kWh per kWp. On a 500 kWp array that is about 25,500 kWh a year between the strongest and weakest town in the county.
Grid connection through UK Power Networks
Connections around Newmarket 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 Suffolk the planning database records 118 solar schemes totalling 1369 MW, of which 23 are operational (REPD Q1 2026).

Questions about solar in Newmarket
- Is there enough sun in Newmarket to make this work?
- Modelled at 905 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 453,000 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 Newmarket?
- 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 East Cambridgeshire?
- 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 East Cambridgeshire first either way.
