### Glossary of Terms

**Summary Metrics:**

Production | The total energy generated during the simulation, in MWh or GWh |

Performance Ratio | Performance Ratio (PR) shows the percentage of total potential energy for the array that is converted to AC energy. Mathematically, the PR is defined as the For example, shading will reduce the PR, since it reduces the AC power, but does not reduce the POA irradiance. However, differences in orientation angle will have very little effect on PR, since the POA irradiance will change with the module orientation. |

kWh/kWp |
The total simulation energy generation divided by the system DC nameplate power. |

** Production Metrics**

Annual Global Horizontal Irradiance | The total irradiance that will fall on a flat plane at the location of the array. This is aggregated directly from the weather file. |

POA Irradiance | The total irradiance in the plane of the modules, accounting for tilt and azimuth angles. This is averaged across all modules in the array. |

Shaded Irradiance | The total irradiance accounting for all shading (from horizon, row-to-row, and obstruction) |

Irradiance after Reflection | The total irradiance after accounting for reflection off the surface of the module (i.e. IAM reflection). |

Irradiance after Soiling | Irradiance after module soiling is accounted for. Note that soiling assumptions are made in the Condition Set. |

Total Collector Irradiance |
The total annual irradiance available to the modules in the array. This is averaged across all modules. |

Nameplate | The maximum potential power of the array, defined as the total collector irradiance multiplied by the system nameplate power. |

Output at Irradiance Levels | The total energy output by the modules, after accounting for low-light effects and module IV curve distortions. More details on Output at Irradiance available here. |

Output at Cell Temperature Derate | The total output of the modules, factoring in the temperature effects on the IV curves. This is the sum of the modules at their maximum power points. |

Output After Mismatch | The total energy output of the modules, factoring in all system constraints (e.g. series & parallel mismatch, voltage drop, etc.). |

Optimizer Output | If DC optimizers are present, this shows the total output of the optimizers, factoring in their efficiency curves and principles of operation. |

System DC Output | The total energy output of the DC system, accounting for all wire resistive losses. |

System AC Output | The total AC energy output from the inverters, taking into account inverter performance losses. |
