PLANT SECTIONS MANAGEMENT MODULE
This module analyses the correct operation of a plant, defines the performance indexes, economic reports and detailed productions for each individual plant section, through the position of the radiation and temperature sensors of the reference module for every section of the plant. Taking advantage of the functionality of eSolar to manage groups of inverters (alias plant sections), it is possible to calculate the production of each plant section, calculate the performance ratio of the section of interest, verify the economic return of each section. During the configuration phase, for each section/inverter unit, it is possible to define:

• rated power and surface of the individual section
• a solar radiation sensor and a temperature sensor reference module among those connected to the eSolar
• an alarm threshold that activates if the performance ratio drops below the value set
• the incentive and amount paid for the section of the plant.
• the monthly detail of the design production data for comparative analysis on an individual section.

It is also possible to configure the expected performance calculation of the plant section. This tool allows to obtain the detail for structuring your own performance calculation algorithm, considering all those parameters deemed indispensable for calculation of the performance ratio of a photovoltaic plant (see IEC EN 61724). Once each individual aspect of every section have been configured, the following can be controlled from the eSolar MANAGEMENT section:

• Real time data. Reading of up to 18 parameters per section, can be “scrolled” on the same page and selected by ticking the box.
• Production data. Detailed analysis of plant production from the point of view of each inverter, with possibility of graphical zooming and definition of the customised analysis time range.
• Expected power. Analysis of plant performance with detail at the individual inverter. Switch between graphic and tabular form data display mode, to check real behaviour compared with expected behaviour.
• Performance Ratio. Analysis of the performance ratio of each section with possibility of detail at the individual inverter. Switch between data display mode in graphical and tabular form, to verify daily performance ratio and plant performance parameters with respect to the reference module temperature. Automatic determination of the sections with better performance.
