As distributed solar photovoltaic (PV) portfolios begin to age, the challenge of measuring performance becomes more relevant. Such an analysis can help financial stakeholders identify performance short-falls and potential warranty items, adjust operational procedures, and evaluate the future value of assets’ performance projections.
