What is the irradiance map of the UK?

Solcast’s irradiance map of the UK is a beneficial tool for solar professionals. From London to Manchester, get real-time and forecast irradiance and PV data based on three-dimensional cloud modelling. Updated every 5-15 minutes, our data is API-ready. Watch how the weather impacts the solar energy resource in United Kingdom - updated daily.

Does the UK need a large-scale solar system?

The study area is the whole of the UK mainland. This developed nation is one of the most densely populated countries in Europe. Yet, only 10% of the land mass is classified as urban, hence theoretically there should be adequate opportunity for establishing large-scale solar installations.

What is the biggest impediment to solar expansion in the UK?

The greatest impediment to utility-scale solar expansion in the UK is the solar energy resource. This removes two-thirds of the British mainland from further investigation. The other land use criteria all carry about the same weight. Official regulations dictate the number, sizes and locations of solar farms which will be established.

Is solar energy a good investment in the UK?

With an expected large solar resource, solar energy has long been considered promising in the United Kingdom . The Department of Energy & Climate Change is leading renewable energy resource monitoring and mapping across the country .

Can a large-scale solar farm be built in the UK?

UK government policy on site suitability for large-scale solar is subject to interpretation. Establishing a solar farm on land classified as agricultural grade 1, 2 or 3a or in ecological areas is not specifically banned, yet it is unlikely planning permission would be granted .

Are solar farms suitable for a high latitude area?

Presents GIS site suitability analysis for solar farms in a high latitude area - UK. Criteria include electricity network connection constraints and government policy. Without these, potential land for utility-scale PV is overestimated by up to 97%. Government plans for future large-scale solar are achievable.
