The seventh edition of the Solar Risk Assessment from kWh Analytics is now available. This annual report brings together data-driven insights from leading voices across the solar industry to explore emerging risks faced by solar developers, operators and financiers.

The 2025 report covers a range of challenges, including:

  • Intensifying extreme weather impacts
  • The need for high data accuracy when training new AI technologies
  • Rising cyber security threats
  • Technical hurdles when managing Battery Energy Storage Systems
  • And more

The 2025 Solar Risk Assessment features contributions from experts at kWh Analytics, Kiwa, Central Michigan University, 60 Hertz, TWAICE, GroundWork, EPRI, Accure Battery Intelligence, VDE, Zeitview, Radian Generation, Clean Energy Associates and Clean Power Research®.

This year, Clean Power Research contributed both SolarAnywhere® data—utilized in a piece by the kWh Analytics team on continued solar asset underperformance (page 12)—and an article on climate change modeling (page 15).

In the article, Lead Product Manager Hang Bui delves into the complex challenge of assessing extreme weather and climate change impacts on projected PV performance.

Conventional site assessments rely on typical meteorological year (TMY) datasets, which reflect long-term historical irradiance and weather. However, as large-scale solar developers express concern with climate change and extreme weather, there is a growing need for an extreme meteorological year dataset that goes beyond the historical framework.

The team at Clean Power Research is currently developing a framework to quantify potential risks and has already completed a case study at an example site in Europe. The study compared modeled data using historical TMY datasets vs datasets created from established climate change models. Although climate modeling showed an increase in sunny days, the negative impact of extreme weather outweighed the PV benefits, resulting in an estimated 4.9% power loss over 30 years.
