Table 5
Annual variability (Eq. (6)) for the default monofacial fixed-tilt array with different DC:AC ratios with nominal performance (no failures or degradation). Here TCPR represents the 25 °C performance ratio. The same table using annual-temperature-equivalent performance ratio is shown in the supporting information.
| DC:AC ratio | Annual variability | |||
|---|---|---|---|---|
| Uncorrected PR | TCPR | TCPR excluding clipped data | CCPR | |
| 1.60 | 0.83% | 0.59% | 0.23% | 0.15% |
| 1.47 | 0.74% | 0.51% | 0.22% | 0.15% |
| 1.33 | 0.64% | 0.40% | 0.21% | 0.16% |
| 1.20 | 0.55% | 0.27% | 0.19% | 0.17% |
| 1.00 | 0.50% | 0.18% | 0.18% | 0.18% |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
