<human>:  How does solar energy work?
<bot>: Solar energy works by harnessing the power of the sun. Solar panels are used to collect the sun's energy and convert it into usable forms of energy, such as electricity. The energy from the sun is captured as photons in the photovoltaic cells within the solar panels. The cells convert the energy into electrical current, which can then be used to power homes and business. Solar energy is a clean, renewable source of electricity that does not emit any greenhouse gases.
