Warranty: The mechanical structures, electrical works and overall workmanship of the grid solar power plants must be warranted for a minimum of 5 years. PV modules used in grid connected solar power plants must be warranted for output wattage, which should not be less than 90% at the end of 10 years and 80% at the end of 25 years. [3]
Recently interest in photovoltaic (PV) power generation systems is increasing rapidly and the installation of large PV systems or large groups of PV systems that are interconnected with the utility grid is accelerating. To maintain the grid stability due to the huge penetration of photovoltaic power to the grid, much stricter grid codes are being imposed by the energy regulatory bodies.

A grid-connected solar PV system needs an inverter to convert the output of the DC-DC converter into AC, which will also inject supraharmonics into the system . Voltage source inverters, current source inverters, and Z- source inverters are the different types of inverters used in solar energy conversion systems [63, 64].
Large scale utilization of solar energy helps promotion of carbon neutrality progress. Photovoltaic power generation system (PVPGS) connects to the grid through converters. However, the PVPGS may trip from the grid under fault since large voltage dip will significantly enlarge the output current of the converter which may exceed the maximum allowable value. Low voltage ride

Grid-connected photovoltaic (PV) systems have become a viable option in low-voltage (LV) networks due to the introduction of lucrative policy frameworks such as metering and significant cost reduction in PV system installation [1, 2, 3]. Consequently, a large amount of rooftop solar PV is expected to be connected to utility grids in coming years.
However, systems like rooftop solar now require the grid to handle two-way electricity flow, as these systems can inject the excess power that they generate back into the grid. Increased solar and DER on the electrical grid means integrating more power electronic devices, which convert energy from one form to another.

Grid interconnection of PV power generation system has the advantage of more effective utilization of generated power. However, the technical requirements from both the utility power system grid side and the PV system side need to be satisfied to ensure the safety of the PV installer and the reliability of the utility grid.
Grid-connected solar PV increased by about 300 MW in Japan and 70 MW in the United States. Several milestones occurred in 2005, such as the commissioning of the world's largest solar PV power plant, 10 MW total, in Germany, and many large commercial installations of tens and hundreds of kilowatts (kW) each.
Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.
