However, NREL researchers can distinguish a module’s degradation profile early in its life with careful indoor current-voltage (I-V) curve measurement methods and higher frequency of measurements. The PV Lifetime Project investigates equipment widely deployed across the United States and across multiple climates.

The degradation of a PV (photovoltaic) module is the term used to describe the steady decline in efficiency and output power of a solar panel over time as a result of numerous environmental influences, manufacturing flaws, and material degradation.

Financially, degradation of a PV module or system is equally important, because a higher degradation rate translates directly into less power produced and, therefore, reduces future cash flows [1]. Furthermore, inaccuracies in determined degradation rates lead directly to increased financial risk [2].

In this paper, we analyzed the long-term performance degradation of PV modules through visual inspection of the modules, measurement of current–voltage (IV) curves normalized to STC.
