As the conventional energy resources are decreasing and energy demand is increasing with time, the future of power generation depends on the nonconventional energy resources. The performance analysis and installation of a power system using NonConventional Energy Resources have been timeconsuming and uneconomical. The major problem with non-conventional energy resource is to analysis the availability of solar energy in any geographical area, initial cost estimation and inaccurate calculations of energy demand. In this paper, an analogy is presented to estimate the solar energy available using ATMEGA16 and MATLAB platform. The proposed scheme has been tested on a virtually designed PV-Array and very efficient MPPT technique. All the generated power then converted from DC to AC using 3-level VSC and fed to an On-Grid System. Analysis of generated power of PV array and electric energy transferred to the grid also has been done to study the performance of solar power plant on changing environmental conditions like temperature, irradiance, and humidity.
