How to pair a solar inverter with a PV plant?
In order to couple a solar inverter with a PV plant, it’s important to check that a few parameters match among them. Once the photovoltaic string is designed, it’s possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).
What is the I-V curve of a solar PV module?
As a standard rule, this curve is available in each PV module’s datasheet and is calculated according to the Standard Test Condition, STC: (1000 W/m2, 25 °C, IAM 1.5). To better understand IAM, read How Radiation and Energy Distribution Work in Solar PV. Figure 3 - Example of I-V curve of a PV module. Image courtesy of PVEducation.
How a transformer is used in a PV inverter?
To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
How do utility scale photovoltaic systems work?
Utility scale photovoltaic (PV) systems are connected to the network at medium or high voltage levels. To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid.
How do I determine the maximum power conditions for a PV module?
Each PV module (or string) can be characterized by an I-V curve (seen in Figure 3) where it is possible to determine the maximum power conditions (Imp, Vmp). As a standard rule, this curve is available in each PV module’s datasheet and is calculated according to the Standard Test Condition, STC: (1000 W/m2, 25 °C, IAM 1.5).
What determines the power of a PV module?
In fact, the PV module’s power largely depends on the climatic conditions of the site (mainly irradiance and temperature). Each PV module (or string) can be characterized by an I-V curve (seen in Figure 3) where it is possible to determine the maximum power conditions (Imp, Vmp).
