The UK has observed a significant increase in solar photovoltaic (PV) gross electricity production from 2013 to 2023. Actual data up to 2023 shows a substantial growth from 7.24 thousand terajoules in 2013 to 59.35 thousand terajoules in 2023, indicating a continual upward trend. The year-on-year variations illustrate notable growth, with 48.49% in 2013, peaking at 101.68% in 2014, and gradually stabilizing to 5.28% in 2023. The compound annual growth rate (CAGR) over five-year periods has decreased from 159.75% in 2013 to 5.3% in 2023, reflecting the earlier rapid growth and the recent stabilization. Forecast data predicts ongoing growth, though at a slower pace, with a forecasted 5-year CAGR of 3.38% from 2024 to 2028, resulting in an 18.06% overall increase by 2028.
Future trends to watch for include advancements in solar technology, policy changes, and investment in renewable energy infrastructure, which could further influence the growth rate of solar PV production. Additionally, the integration of solar PV with energy storage solutions could play a crucial role in enhancing the stability and reliability of solar power as a significant energy source for the UK.
