What is the primary function of solar panels?

The primary function of solar panels is to gather energy from the Sun and convert it into usable electricity. Solar panels are made up of photovoltaic cells that capture sunlight and convert it into electrical energy through the photovoltaic effect. This energy can then be used to power homes, businesses, and other electrical devices. The ability to harness clean and renewable energy from the Sun is a significant aspect of solar technology, making it an essential tool in promoting sustainable energy practices.

While some of the other options mention related concepts, such as measuring solar radiation or tracking the Sun’s movement, they do not accurately describe the core function of solar panels, which is focused specifically on energy collection and conversion.
