Ten largest UK solar farms
The UK's utility-scale solar fleet is led by a handful of very large parks in southern and eastern England, where solar yield is highest. The table below lists the ten largest mapped sites by nameplate capacity.
| # | Solar farm | Capacity (MW) | Operator | Location |
|---|---|---|---|---|
| 1 | Cleve Hill Solar Park | 373 | Cleve Hill Solar Park Ltd | Kent |
| 2 | Llanwern Solar Farm | 75 | — | Newport, Wales |
| 3 | Shotwick Solar Park | 72 | We-Link Energy / Compton Group | Flintshire |
| 4 | DTTC Lyneham Solar Farm | 69.5 | Defence Infrastructure Organisation | Wiltshire |
| 5 | Breach Solar Farm | 68 | — | Suffolk |
| 6 | Darlington Road Solar Farm | 55 | Atrato Onsite / Harmony Energy | County Durham |
| 7 | South Fambridge Hall Solar Farm | 52.5 | BayWa r.e. UK | Essex |
| 8 | Chapel Lane Solar Farm | 51.3 | Eco Sustainable Solutions | Dorset |
| 9 | Owl's Hatch Solar Farm | 50 | British Solar Renewables | Kent |
| 10 | Scottow Solar Power Station | 50 | Greencoat Solar | Norfolk |
UK solar capacity by region
Sunnier southern and eastern England account for the bulk of the UK's utility-scale solar fleet. The table below groups mapped sites into broad regions and shows how capacity is distributed across the country.
| Region | Mapped sites | Capacity (MW) | Share |
|---|---|---|---|
| South / East England | 301 | 2,955 | 25.6% |
| Midlands | 412 | 2,866 | 24.9% |
| South-West England | 522 | 2,788 | 24.2% |
| North England | 287 | 1,323 | 11.5% |
| Wales | 206 | 1,117 | 9.7% |
| Scotland | 173 | 246 | 2.1% |
| Northern Ireland | 28 | 228 | 2.0% |
When were UK solar farms built?
Bars show the annual capacity added across sites with a recorded commissioning date in OpenStreetMap. The mid-2010s saw the first wave of subsidised solar farms; activity then dipped before a strong rebound from 2023 onward as larger NSIP-scale projects came online.
Only includes sites where a start_date is recorded in OpenStreetMap. Most older sites are not dated so the totals are indicative rather than complete.
About this map
The map is built from OpenStreetMap data, queried through the Overpass API and filtered to the UK bounding area. It includes every feature tagged as a solar power plant (power=plant, plant:source=solar) plus individual solar generators of 100 kW and above. Rooftop PV on single houses is not shown — the focus is on commercial, community and utility-scale sites.
Capacity values are converted to kW from whatever units the OSM contributor entered (W, kW, MW, GW). Where a site has been mapped but no capacity recorded, the marker still appears on the map but doesn't count toward the mapped-MW total. That means the true installed capacity across these sites is higher than the figure shown in the map header.
If you spot a missing or incorrect site, you can edit it directly on OpenStreetMap and the next refresh of this page will pick it up.
Frequently asked questions
How many solar farms are there in the UK?
OpenStreetMap records roughly 1,900 solar power plants and large solar installations across Great Britain and Northern Ireland, representing over 11 GW of mapped capacity. The true figure is higher because not every commissioned site has been mapped yet and many small rooftop systems are excluded from this map.
What is the largest solar farm in the UK?
Cleve Hill Solar Park in Kent is the largest operational solar farm in the UK at 373 MW. It was the first UK solar project consented under the Nationally Significant Infrastructure Projects (NSIP) regime and began generating in 2024.
Where is the data from?
All points come from the OpenStreetMap project, tagged with power=plant and plant:source=solar, or power=generator with generator:source=solar. Data is licensed under the Open Database License (ODbL). We include all mapped plants plus individual generators of 100 kW or larger.
How accurate is the data?
OpenStreetMap is crowd-sourced, so coverage is best for named utility-scale solar farms and weaker for smaller commercial rooftops. Capacity figures reflect what contributors have entered — some sites have no capacity value and are not counted in the mapped MW total.
Can I use this data?
Yes. The underlying OpenStreetMap data is free to use under the Open Database License, provided you attribute OpenStreetMap contributors. Download the raw GeoJSON directly at /data/uk-solar-plants.geojson.
