The conversion efficiency of photovoltaic panels refers to the percentage of sunlight that is converted into usable electricity. Recent advancements in photovoltaic technology have increased the average efficiency from 15% to over 23%1. The conversion efficiency is crucial for making PV technologies competitive with conventional energy sources, as it directly impacts the amount of electricity generated from solar energy2. Additionally, the efficiency can be assessed through the current versus voltage characteristics of the panels, which helps in determining their quality and performance under various conditions3.
