### 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 in the following formula: In the report above we find the following values: Energy to Grid: 98,619.3 kWh DC Nameplate: 57.5 kW POA Irradiance: 2,069.3 kWh/m2 We can calculate the performance ratio as 98,619.3 / (2069.3 * 57.5) = 82.9%  Note: rounding in POA Irradiance and DC nameplate can cause slight rounding errors in the calculation. To get the full POA irradiance value, you would need to use the hourly CSV export. To get full DC nameplate multiply module count by module wattage.  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.   * STC stands for Standard Test Conditions. These are measured under lab conditions of 1000W per sq meter of irradiance and 25 degree C. kWh/kWp The total simulation energy generation divided by the system DC nameplate power.
