Therefore, it was found that solar photovoltaic–thermal coupling (PVT) could be a practical route for more sustainable solar desalination as its use led to improved solar energy efficiency, specific water production, and specific energy consumption (He et al. 2023b).

Solar energy is used in two different ways: one through the solar thermal route using solar collectors, heaters, dryers, etc., and the other through the solar electricity route using SPV, as shown in Fig. 1.A SPV system consists of arrays and combinations of PV panels, a charge controller for direct current (DC) and alternating current

There is a paradox involved in the operation of photovoltaic (PV) systems; although sunlight is critical for PV systems to produce electricity, it also elevates the operating temperature of the panels. This excess heat reduces both the lifespan and efficiency of the system. The temperature rise of the PV system can be curbed by the implementation of
Photovoltaic power generation is non-ionizing radiation. It converts light energy directly into DC power through the characteristics of semiconductors, and then converts the DC power into AC power that can be used by us through an inverter with 12v battery.

Solar radiation (Rs) is defined as the amount of energy radiated from the sun in the form of electromagnetic waves that reaches the Earth surface. You might find these chapters and articles relevant to this topic. A. Fernández-García, M. Pérez, in Renewable and Sustainable Energy Reviews, 2010
The sum of direct and scattered solar radiation reaching the ground after atmospheric weakening is called total solar radiation. On the global average, total solar radiation accounts for only 45% of the solar radiation reaching the upper limit of the atmosphere.
Therefore, solar radiation level has a direct effect on the panel power. As a result, a decrease in solar radiation level reduces the panel power. On the other hand, there is an inverse proportion between temperature and panel power. In other words, panel power decreases as the ambient temperature increases.
Findings and recommendations from the study can be outlined as follows: PV output significantly depends on available solar energy falling directly on the module, and 0.08% loss occurs for each degree of deviation from the direct component of solar irradiance. This can be minimized by facing the PV panel always to sun position.
The total solar radiation is maximum around noon in the day, and 0 at night. The radiation energy in VIS (0.4–0.76 μm), IR (>0.76) μm), and UV (<0.4 μm) accounts for 50%, 43%, and 7% of the total solar radiation respectively. Thus, the radiation energy is concentrated in the short-wave bands, and solar radiation is also called short-wave radiation.
