A grid-tied solar system has a special inverter that can receive power from the grid or send grid-quality AC power to the utility grid when there is an excess of energy from the solar system. Figure. Grid-Connected Solar PV System Block Diagram. In addition, the utility company can produce power from solar farms and send power to the grid directly.
Photovoltaic (PV) is one of the cleanest, most accessible, most widely available renewable energy sources. The cost of a PV system is continually decreasing due to technical breakthroughs in material and manufacturing processes, making it the cheapest energy source for widespread deployment in the future [1].Worldwide installed solar PV capacity reached 580
When solar PV system operates in off-grid to meet remote load demand alternate energy sources can be identified, such as hybrid grid-tied or battery storage system for stable power supply.
Grid-connected PV inverters have traditionally been thought as active power
Grid-connected PV systems enable homes to use less energy from the grid
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer
Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid. The application of the system will determine the system''s configuration and size. Residential grid-connected PV systems are typically rated at less than 20 kW. In contrast, commercial systems are
In photovoltaic (PV) systems, inverters have an essential role in providing an energy supply to meet the demand with power quality. Inverters inject energy into the grid considering that a renewable source is available; however, during intermittent periods or in the absence of power generation, the inverter remains inactive, which decreases the performance

Grid-Connected PV system. The major component in both systems is the DC-AC inverter or also called the power conditioning unit (PCU). The inverter is the key to the successful operation of the system, but it is also the most complex hardware.
The novelty of the proposed work is to model a grid-connected SPV system without the use of a separate DC-DC converter; i.e., the PV power is injected into the grid with a single-stage converter (DC/AC) system by the use of an adaptive control technique. This will reduce investment costs and losses compared to the two-stage conversion process.
