I'm interested in understanding the functionality of solar panels and how they convert sunlight into usable energy. Specifically, I'd like to know about the underlying technology involved in the process, including the role of photovoltaic cells. Additionally, could you provide information on the efficiency rates and any factors that may influence their performance? Understanding these details will help in making informed decisions about potential procurement options. Thanks!
