Solar panels and solar thermal collectors serve different purposes in harnessing solar energy. Solar panels, or photovoltaic (PV) panels, convert sunlight directly into electricity using semiconductor materials that generate an electric current when exposed to light. The process involves the photovoltaic effect, where photons from sunlight knock electrons loose from atoms in the semiconductor, creating an electric flow. In contrast, solar thermal collectors absorb sunlight to heat a fluid, typically water or air, which can then be used for heating applications or to generate steam for electricity production. The key difference lies in their output: solar panels produce electricity, while solar thermal collectors produce heat. Understanding these distinctions is crucial for choosing the right technology for specific energy needs.<|im_end|>

Solar panels and solar thermal collectors are both used in solar energy. Solar panels make electricity, while thermal collectors heat water. They are different technologies, but both are related to solar energy. Solar panels use some kind of material to catch sunlight, and thermal collectors use a fluid. It's important to know they don't do the same thing, but they are both parts of renewable energy systems.<|im_end|>
