Power Quality Performance Evaluation of Grid-Connected PV Systems refers to the process of evaluating and analyzing the quality of electrical power generated by a grid-connected solar photovoltaic (PV) system.

The Performance Ratio (PR) of the PV system, as defined in IEC 61724, ranges from 0.6 to 0.8 for daily irradiation higher than 2.0 kWh/m 2 (Fig. 6) This is a relatively high value compared with other small grid-connected systems. For lower irradiance values, the PR is lower due to the non-linear characteristics of the PV system''s components.
The daily photovoltaic array yield is given by (1) η PV,d =E PV,d /E r,d, where E PV,d is the daily energy (in kWh) supplied by the modules and E r,d the available daily energy, defined as the daily irradiation on the plane of the array surface during the time when the inverter is connected to the grid.

PVGIS is a web site that gives you information about solar radiation and PhotoVoltaic (PV) system performance. You can use PVGIS to calculate how much energy you can get from different kinds of PV systems at nearly any place in the world.
Grid-connected solar PV systems operate in two ways, the first is the entire power generation fed to the main grid in regulated feed-in tariffs (FiT), and the second method is the net metering approach.
Finally, the proposed grid-connected SPV system was simulated on MATLAB for analyzing the performance of the system based on its I-V and P-V characteristics, inverter voltage, grid power, gird voltage, grid current, power factor, and THD under different environmental conditions.
Some additional information about the calculation is also supplied in the output. PVGIS interface: you will get only the fixed mounting output if you use the "Fixed grid-connected" tool, and only the tracking system output if you use the "Tracking grid-connected" tool. See below for the details about these outputs.
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.
