Does Solar Thermal Use Solar Panels

Solar thermal is currently used more often on large scale applications where lots of hot water is needed like a laundromat or a college dorm.

Does solar thermal use solar panels.

Differences between solar thermal and pv solar panels. The basic principals behind modern solar thermal systems. This is then used to heat your water which is stored in a hot water cylinder. Solar thermal power electric generation systems collect and concentrate sunlight to produce the high temperature heat needed to generate electricity.

Solar thermal power systems use concentrated solar energy. Reflectors mirrors that capture and focus sunlight onto a receiver. The main source of heat generation is through roof mounted solar panels which are used in conjunction with a boiler collector or immersion heater. Photovoltaic pv systems generate electricity rather than heat.

An immersion heater unvented hot water cylinder might be needed as a back up heater or to get the water to the temperature you want. Pv converts sunlight directly into electricity. Solar thermal panels use heat from the sun to warm fluid passing through them as the diagram below shows. All solar thermal power systems have solar energy collectors with two main components.

Solar thermal uses the sun s energy to generate thermal energy which is used to heat water or other fluids. These solar cells are usually found powering devices such as watches sunglasses and backpacks as well as providing power in remote areas. In the case of a solar thermal panel we are trying to heat above the ambient temperature so conduction and convection will work against us by taking heat from the panel to the out side world. The only way you can get a higher temperature than ambient is by radiation therefore all solar collectors rely on solar radiation.
