Research by 3E and Statkraft has used a new performance measure for solar trackers to uncover “alarming” evidence of a gap between claimed and actual performance.
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.
