Commercial building solar panels in Clacton-on-Sea
For a landlord in Clacton-on-Sea, a roof array is increasingly a question about the EPC rating as much as the electricity bill. Each survey records the usable area once edge strips, plant and walkways are taken out, the load the deck can take, and whether the lease lets the occupier alter the roof.
973 kWh per kWp a year at this latitude, so a 210 kWp array models at about 204,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for offices and retail across Essex
How much sun a Clacton-on-Sea roof gets
Modelled irradiation here is 1,232 kWh per square metre a year on a low-tilt array, which works out at 973 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 10 percent above the mean across the towns we cover.
The rating list for Tendring
The Valuation Office Agency's rating list puts 690 office and 1,230 retail properties in Tendring, covering about 63,000 and 210,000 square metres of floorspace respectively. By office stock the district sits below the median of the 318 districts in England and Wales; by retail stock it sits above the median of the 318 districts in England and Wales.
40 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 76,000 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 350 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 53,200 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 CO postcodes, CO15 outward.
Clacton-on-Sea ranks 1 of 10 towns we cover in Essex on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 908 to 973, a spread of 65 kWh per kWp. On a 210 kWp commercial roof that is about 13,650 kWh a year between the strongest and weakest town in the county.

Grid connection through UK Power Networks
Connections around Clacton-on-Sea 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 Essex the planning database records 221 solar schemes totalling 2787 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in Clacton-on-Sea
- How much would solar on a commercial building in Clacton-on-Sea generate?
- The model gives 973 kWh for every kWp installed here, so 210 kWp is about 204,000 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 Clacton-on-Sea 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 Tendring 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 Clacton-on-Sea?
- 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 Clacton-on-Sea have capacity for export?
- UK Power Networks is the distribution network operator for Essex. 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.
