performance ratio

As it matures, the solar industry is moving beyond the use of Performance Ratios (PR) as the go-to performance metric for operational sites. Christopher West, head of central engineering - solar PV delivery unit at Statkraft, argues the case for PRs to be replaced by alternative, more evolved methods of assessment.

Utility-scale solar is evolving beyond traditional measurements, and performance ratio are one such metric that is likely to become obsolete, replaced by more modern criteria such as availability metrics. Carsten Steenberg, VP of product management and business development at Rainwise, explores the new metrics coming to the fore and discusses the importance of weather monitoring.
