This page offers a detailed analysis of energy losses associated with nominal plant capacity (NPC), also known as site export limit. These losses occur when the solar farm is operating at its maximum capacity at the Point of Interconnection. The grid operator usually establishes this capacity limit to prevent grid-related issues during the site's commissioning.
Nominal Plant Capacity Summary
The high-level KPIs are displayed including the nominal plant capacity percentage, energy losses, and associated revenue loss, are displayed. This summary helps users assess the material and financial impact of nominal plant capacity on their sites.
Nominal Plant Capacity per inverter and power curve
The NPC Energy Losses per Inverter chart visualizes energy losses due to nominal plant capacity for each inverter, with an average NPC Energy Loss line as a reference. Users can select a specific inverter by clicking on its bar to analyze its performance in detail. Additionally, the Power Curve per Inverter displays a scatter plot of active power versus irradiance for the selected inverter, helping users identify outliers and better understand the issue.
Daily Nominal Plant Capacity per inverter over time
The Daily NPC Energy Losses features an insightful heatmap that illustrates daily energy losses for each inverter. This powerful visualization empowers users to identify trends, compare NPC losses across different inverters, and monitor the changes in losses over time. By leveraging this information, users can enhance their system performance analysis and optimize operations effectively.
