Solar thermal panels seem to be cheaper than solar photovoltaic (PV) systems with a typical payback period of around 7–11 years [ 74 ]. In this context, the use of this technology can help to harness a clean and renewable source of energy to provide heating, while receiving a return on the investments made.
PV panels are used to produce electricity from the solar energy directly. On the other hand, solar thermal technologies take advantage of the solar energy to generate heat. Nevertheless, a combination of the two or PV/T solar panels uses the solar energy to produce both electricity and heat.
These technologies are namely photovoltaics (PV), solar thermal, photovoltaic-thermal (PV/T) and concentrating solar panels. PV panels are mainly used to produce electricity from the solar energy directly, whereas solar thermal technologies take advantage of the solar energy to generate heat.
On the other hand, with the use of thermal solar panels, heat can be absorbed from the sunlight to produce thermal energy or transfer that to a medium like water. The hot water for example can then be supplied to consumers, which reduces the need for employing fossil fuels for this purpose.
Hybrid solar photovoltaic thermal (PV/T) panels Hybrid solar photovoltaic thermal (PV/T) panels embrace a combination of thermal collectors with photovoltaic (PV) modules. These panels seem to have a very high efficiency as they work by producing both heat and electrical energy.
Therefore, this article focused on the three different types of solar panels, their functionalities and ability to achieve efficiency while keeping the costs down. Specifically, the development and functionality of photovoltaics (PV), thermal and photovoltaic-thermal (PV/T) panels were studied.
