Commercial building solar panels in Eastbourne
Whether solar pays on a Eastbourne 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.
1017 kWh per kWp a year at this latitude, so a 210 kWp array models at about 214,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a flat roof in Eastbourne generates
Modelled irradiation here is 1,283 kWh per square metre a year on a low-tilt array, which works out at 1017 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 15 percent above the mean across the towns we cover.
Commercial stock in Eastbourne
Eastbourne has 500 office premises and 1,070 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 bottom quarter of the 318 districts in England and Wales; by retail stock it sits below the median of the 318 districts in England and Wales.
50 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 123,000 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 180 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.

Questions about solar in Eastbourne
- What would a 210 kWp array produce in Eastbourne?
- Yes. At 1017 kWh per kWp a year, a 210 kWp array on a Eastbourne roof models at around 214,000 kWh. What changes the answer is how much of that the building uses during opening hours rather than exports. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Is planning permission needed for panels on a Eastbourne 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 Eastbourne 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 Eastbourne?
- 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.
