Can Solar PV performance measurements rely on historical irradiance averages?

Updated: Aug 20, 2023

According to PV Magazine, during March 2022 Europe experienced an abnormal phenomenon affecting solar energy output. Spain, known for producing high levels of solar energy, saw a 50% decrease in monthly solar irradiance compared with historical averages. Meanwhile, Germany and the Balkans underwent solar irradiance 45% above average compared to the past 28 years.


Solar flux is apparently not as predictable as many would like to think. This extreme deviation implies a low reliability when using monthly average irradiance datasets to assess PV system performance. As the hardware behind solar panels continues to improve, financial models must also become more resilient and accurate.


How can you better assess solar PV performance to ensure a more efficient energy production, and therefore higher yields and financial feasibility of projects? What methods and technologies for performance analytics are relevant to decentralized PV?

Tune in to the Solar PV performance and its Financial Implications workshop on July 28th 2022 to learn more.
