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 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.
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.
