Photovoltaic (PV) solar panels are devices that convert sunlight directly into electricity using the photovoltaic effect, a process that generates electrical current when certain materials are exposed to sunlight. How PV Solar Panels Work:
Unlike solar panels (which convert sunlight directly into electricity), solar thermal systems capture the sun’s heat and use it for various practical applications. How Solar Thermal Energy Works: Solar Collectors: Solar thermal systems use collectors to absorb sunlight and convert it into heat.
On the other hand, Solar Panels convert sunlight directly into electricity using photovoltaic cells, which can be used for residential, commercial, and utility-scale power generation. Let’s dive deeper into each technology to understand their workings, benefits, and best use cases. What is Solar Thermal Energy?
A PV module exposed to sunlight generates heat as well as electricity. For a typical commercial PV module operating at its maximum power point, only about 20% of the incident sunlight is converted into electricity, with much of the remainder being converted into heat. The factors which affect the heating of the module are:
Generation of DC Electricity: The generated electricity is in the form of direct current (DC) electricity, which flows out of the solar panels through wires.
Components of a Solar PV System: Solar Panels: Made up of photovoltaic cells that generate electricity when exposed to sunlight. Types include monocrystalline, polycrystalline, and thin-film panels. Inverter: Converts DC electricity from the solar panels into AC electricity suitable for household use or grid connection.
