1. Solar panels: Solar panels are the most common method of harvesting solar heat energy. These panels are made up of photovoltaic cells that convert sunlight into electricity.
2. Solar water heaters: Solar water heaters use the heat from the sun to heat water for residential or commercial use. These systems typically consist of solar collectors, a heat exchanger, and a storage tank.
3. Solar air heaters: Solar air heaters use the sun's heat to warm air, which can then be used to heat buildings or provide hot air for industrial processes.
4. Solar cookers: Solar cookers use the heat from the sun to cook food. These devices can be simple, like a solar oven made from a cardboard box and aluminum foil, or more complex, like a parabolic solar cooker.
5. Solar distillation: Solar distillation is a method of using the sun's heat to evaporate water and collect the condensed vapor for drinking water or other uses.
6. Solar thermal power plants: Solar thermal power plants use mirrors or lenses to concentrate sunlight onto a receiver, which then converts the heat into electricity using a steam turbine.
7. Solar chimneys: Solar chimneys use the sun's heat to create a temperature difference between the air inside and outside a tall chimney, which causes air to flow through the chimney and drive a turbine to generate electricity.
