Local irradiance data

Why London is strong territory for high-yield solar.

London receives an average of 3.8 peak sun hours per year — above the UK national average of 3.4, driven by the South East's higher irradiance profile. A typical 4kWp London residential system generates approximately 3,800kWh annually — equivalent to 85% of an average household's consumption. Many London properties fall within conservation areas or are listed buildings; First Choice Solar's surveying team assesses planning requirements at the survey stage. Solar panels are generally permitted development for most London houses.
