Photovoltaic panel power interface

What is a photovoltaic system?

Photovoltaic or PV system are leading this revolution by utilizing the available power of the sun and transforming it from DC to AC power.

How a PV inverter works?

The inverter converts DC power to AC power through a solid state switching action used to feed energy generated by a PV generator into the utility grid. High efficiency of these converters is a major requirement . The solution to control the power injected into the grid are essential for effectiveness of the system.

How to control a grid-connected photovoltaic system?

The control of a grid-connected photovoltaic system can be divided into two important parts: (1) MPPT controller to extract the maximum power from the PV modules, and (2) Inverter controller, which ensures the control of active and reactive powers injected into the utility grid and the control of DC-link voltage.

Are power converters a good choice for PV panels?

The efficiency, reliability and cost-effectiveness of the power converters used to interface PV panels to the mains grid and other types of off-grid loads are of major concern in the process of system design. This book describes state-of-the-art power electronic converter topologies used in various PV power conversion schemes.

How do PV panels work?

The required voltage and power is produced by grouping the PV cells in series and parallel forming the modules. Modules are combined to form PV panels. These panels are connected together to build up the entire PV array and any desired current-voltage characteristics could be generated , .

Are photovoltaic systems more efficient if connected in parallel?

IEC 61727 Complaint Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy this can be utilized and the grid energy used at other times. For large PV systems, any connection interface is likely to need discussion with the power network operator.
