Solar panels, also known as photovoltaic panels, are an increasingly popular form of renewable energy. But did you know that there are several synonyms for this commonly used term? One of the most common is solar module, which refers to a single panel containing multiple solar cells. Other synonyms include solar array, which refers to a group of solar panels connected together, and solar collector, which typically refers to a specialized type of solar panel used for heating water or air. Some other possible synonyms for solar panel might include photovoltaic cell, solar panel system, or even simply solar energy technology. No matter what terminology you use, however, the basic concept remains the same: harnessing the power of the sun to create clean, renewable energy.
