Experimental Findings & Validation
The increasing concern regarding climate change, greenhouse gas emissions, and depletion of fossil fuel resources has motivated governments and industries worldwide to adopt renewable energy technologies. Solar photovoltaic (PV) energy has become one of the fastest-growing renewable energy sectors because of its unlimited availability, environmental sustainability, and technological maturity . According to recent global energy reports, solar photovoltaic installations have experienced exponential growth during the last decade, accounting for a significant portion of newly installed renewable energy capacity worldwide . Continuous improvements in solar cell manufacturing technologies, declining module costs, and supportive governmental policies have further accelerated the adoption of PV systems in residential, commercial, and utility-scale applications. The efficient utilization of photovoltaic energy requires sophisticated power electronic interfaces capable of converting the variable DC output of solar panels into high-quality AC power suitable for utility grids . The inverter serves as the most important component in this conversion process, significantly influencing the overall efficiency, reliability, and economic viability of the photovoltaic system.
