Commercial building solar panels in Felixstowe
Whether solar pays on a Felixstowe commercial building depends less on the panels than on who owns the roof and who pays the bill. The survey starts with the membrane and the deck: how many years the covering has left, what the roof can carry in ballast, and where plant and its shade rule panels out.
950 kWh per kWp a year at this latitude, so a 210 kWp array models at about 200,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar PV for commercial property across Suffolk
What a flat roof in Felixstowe generates
Modelled irradiation here is 1,212 kWh per square metre a year on a low-tilt array, which works out at 950 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 7 percent above the mean across the towns we cover.
Commercial stock in East Suffolk
East Suffolk has 1,530 office premises and 2,210 shops and other retail premises on the non-domestic rating list, according to the Valuation Office Agency. By office stock the district sits in the top quarter of the 318 districts in England and Wales; by retail stock it sits in the top quarter of the 318 districts in England and Wales.
90 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 181,000 square metres. Single storey boxes of that size are where most commercial rooftop solar actually gets built, because the roof is big, flat or shallow, and uninterrupted.
The same list carries 580 hotel, leisure and assembly properties in the district. Leisure centres and hotels run seven days a week, which puts weekend generation to use that an office would export.

The built-up area holds about 24,220 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).
Surveys run across IP postcodes, IP11 outward.
Felixstowe ranks 2 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 210 kWp commercial roof that is about 10,710 kWh a year between the strongest and weakest town in the county.

Grid connection through UK Power Networks
Connections around Felixstowe 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 commercial building 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 Felixstowe
- How much would solar on a commercial building in Felixstowe generate?
- The model gives 950 kWh for every kWp installed here, so 210 kWp is about 200,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Is planning permission needed for panels on a Felixstowe office or shop?
- Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to East Suffolk for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.
- Will rooftop solar improve the EPC rating of a let building in Felixstowe?
- It can. A non-domestic EPC is an asset rating, and on-site generation counts in the calculation, so an array usually lifts the score. Let property in England and Wales must be EPC E or better today. The government's interim response of 18 June 2026 proposes EPC B, where cost effective, from 2031 for let buildings over 1,000 m², and drops the EPC C step once planned for 2027. How far solar moves a particular building depends on its fabric and services, which is why the EPC assessor models it before anything is fitted.
- Does the grid around Felixstowe have capacity for export?
- UK Power Networks is the distribution network operator for Suffolk. Arrays above 3.68 kW per phase connect under G99, and the application sets the export limit. It is part of the design work we arrange.
