This approach allows selecting models that offer the best trade-off between predictive accuracy and environmental responsibility.

The results show that PV integration can reduce primary energy consumption by up to 63%, with a decarbonization rate of 11%.

The characteristics of lemons were easy to harm; proper preservation methods were needed. The solar dryer preservation method becomes a solution regarding to the problem concerned. Drying uses the novel indirect solar dryer with double glazing technology, a V-groove absorber, heat storage, heat recovery, and photovoltaic (PV) used in drying lemon slices. This research is limited to the use of a solar dryer with these specifications in influencing lemon slices (95.77 %w.b) with and without sucrose blanching treatment. Drying process was carried out for 32 h in 4 days. The drying behavior of the samples was determined by water content, drying rate, modeling, visible object, and antioxidant activity. The research results showed that the final water content of lemon slices with and without sucrose blanching was 11.98 %w.b and 14.61 %w.b. The most considerable drying rate occurred in lemon slices with sucrose blanching with a range of 0.007–0.085 %w.b/min. Based on model accuracy tests, the best modelling results for lemon slices were obtained using the Two Term Exponential Model (blanching) and the Modified Page Model (without blanching).

To address these issues, an AlO<sub>x</sub>-SiO<sub>x</sub> hybrid coating that combines the beneficial properties of alumina and silica to improve both anti-reflective and anti-fogging characteristics has been developed.

Anti-fogging tests confirm the coating’s efficacy in resisting fog formation. The hybrid coating exhibits improved hardness and anti-fogging properties due to its network-like structure.

PDRC paints are highly desirable due to their advantages of being metal-free, having a simple single-layer structure, providing good conformality, and allowing for facile large-area manufacturing. However, many PDRC materials face challenges such as the need for improved solar reflectance and thermal radiation, reliance on fluorine substances, and inconsistent assessment protocols. These challenges can lead to potential environmental issues and inconsistent or erroneous data. To address these limitations, we develop a hydrophobic, fluorine-free PDRC paint, based on a Y<sub>2</sub>O<sub>3</sub>-poly(methylphenysiloxane) (PMPS) filler-binder composite. The Y<sub>2</sub>O<sub>3</sub> fillers possess a large energy gap of 5.6 eV and a high refractive index above 1.9, resulting in an absolute solar reflectance of 96.1 % and mid-infrared emissivity of 0.97. The proposed reproducible assessment protocols, for the first time, enable the measurement of cooling performance using commercially available Stevenson screens without any involvement of homemade components. These protocols demonstrate that the fluorine-free PDRC paint realizes a sub-ambient cooling temperature of up to 4.8 °C, with an average of 2.4 °C under direct sunlight with a maximum solar irradiance of 902 W m<sup>−2</sup> during continuous 24-hour measurements.
