Solar Photovoltaic Thermal (PVT) systems offer significant efficiency dividends for hot water-intensive businesses by converting solar irradiance into both electricity and usable heat. These systems harness the solar spectrum more effectively than traditional photovoltaic (PV) panels by mitigating thermalization losses-where excess heat is not converted into electricity and is usually wasted.
PVT systems capitalize on this otherwise lost thermal energy by transferring it from the PV cells to a fluid, yielding additional thermal energy that can be used for heating purposes. The technical advantage of PVT systems lies in their ability to achieve considerable thermal efficiency, typically around 60%, despite the presence of optical losses where some sunlight is reflected or not transmitted through the panel's cover.
Electrical gains in PVT systems are also notable, standing at around 15%. These figures underscore the system's capability to transform a substantial fraction of the solar spectrum into electrical energy, which is crucial for the overall energy yield of the system. Meanwhile, heat losses through conduction, convection, and radiation are an area of focus to ensure thermal efficiency remains high.
Minimizing these losses is critical to enhancing the PVT system's performance and maximizing the return on investment through efficiency dividends. The dual functionality of PVT systems to provide both heat and power makes them a financially and environmentally attractive choice for businesses requiring large quantities of hot water.
