Losses in Glint Solar vs. losses in PVsyst
The table below shows how losses recorded in Glint Solar correspond to losses recorded in PVsyst.
| Glint Solar | PVsyst | Notes |
| Meteo data base | Meteonorm 8.2.0.21236 | |
| Horizon shading | Farshading loss (only in losses diagram) | |
| Dirt and soiling | Soiling loss | |
| Near shading: irradiance loss | Shading loss | |
| Reflection (IAM) | IAM loss (only in losses diagram) | |
| Bifaciality | - | In PVsyst, "bifaciality" is the performance factor of the back side relative to the front side. For example, if the bifaciality is 0.7, this means that the back side will be 70% as good as the front side. In Glint Solar, "Bifacial gain" instead corresponds to the bifacial gain, which is displayed as a gain in the loss diagram in PVsyst. |
| Irradiances dependencies | - | Glint Solar does not explicitly state how much is lost due to low irradiation levels. However, this is taken into account in the conversion of irradiation into electricity. |
| Near shading: electrical loss according to strings | Electrical losses due to shading (only in losses diagram) | |
| Power tolerance of modules | Nameplate rating loss | |
| Temperature dependencies | Temperature loss (only in losses diagram) | |
| Spectral correction | Spectral correction (only in losses diagram) | |
| Light induced degradation (LID, initial) | Light-induced degradation | |
| Mismatching Modules | Mismatch losses | Match losses due to shading are calculated in "electrical losses due to shading" in Glint Solar. |
| Mismatching Strings | ||
| Mismatching back face | ||
| DC cabling | Wiring losses | Glint Solar captures "connection losses". Connection losses are the losses between cabling and diodes. |
| AC cabling | ||
| HTA cabling | ||
| Transformer | Glint solar does not yet support transformers. | |
| Inverter | Inverter | Only in the pattern of losses. It is not possible to make inverter losses. |
| Auxiliaires | - | Glint Solar has no “auxiliary” losses. To add these losses, you can add the losses to other loss categories (fouling or conductors). |
| Additional | - | Glint Solar does not have an "other" loss category. |
| Unavailability of the system | Availability Loss | |
| Vieillissement | Annual Degradation | |
| Albedo | Albedo 0,2 |
