How Nefyn (Tyddyn Cae) compares

433rd of 662largest solar farms in the UK register
46th of 75in Wales
0.09%of listed UK solar farms capacity
β‰ˆ 4.3 GWhillustrative output a year

At a typical UK load factor for this technology (about 10% of the maximum possible output), a 4.92 MW station would generate roughly 4.3 GWh of electricity in a year, similar to the annual use of about 1,600 homes at 2,700 kWh each. This is an illustrative estimate, not the station's metered output: real generation varies with weather, availability and grid constraints.

Solar photovoltaic (PV) sites generate electricity from sunlight. Panels produce direct current, which inverters convert to alternating current for the grid. Output follows daylight and the seasons, so annual generation is a small fraction of the maximum possible.
