Two new metrics, Solar Volatility and Solar Deviation, are introduced to quantify the variability of PV output compared with expected output. These metrics are applied to the time series power data from over 1000 systems each around Los Angeles and Newark.
As photovoltaic penetration of the power grid increases, accurate predictions of return on investment require accurate prediction of decreased power output over time. Degradation rates must be known in order to predict power delivery. This article reviews degradation rates of flat-plate terrestrial modules and throughout the last 40years.
We hope this synopsis of some important causes of reduced energy production from your solar PV systems–tilt and orientation, incident angle modifier, environmental conditions, and inverter clipping–helps you maximize the output of your systems. This article is part of Aurora’s PV System Losses Series.
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 . Furthermore, inaccuracies in determined degradation rates lead directly to increased financial risk .
This trend is readily explainable by the more widespread availability of solar simulators. Figure7 indicates the number of measurements that were taken to measure degradation rates. It is noteworthy that a high percentage of references take only one or two measurements to report degradation rates.
