<p>An increase in population, limited agricultural yield, and adverse climatic conditions present a significant threat to food security, yet the subject is under-researched globally and in India. Investing in agricultural post-harvest loss related to renewable energy and energy efficiency interventions is crucial to reducing post-harvest loss, global hunger, and farmer exploitation. Although considerable work is reported on drying and cooling techniques to reduce post-harvest losses, the objective of this study is to discuss novel energy-efficient technology, including simultaneous cooling and drying options, so that it can reduce post-harvest losses. The various integrations of solar PV/T-assisted refrigeration systems, such as heat pump, vapor compression refrigeration systems, and vapor absorption refrigeration systems, are discussed here. This integration aims to achieve a cost-effective, energy-efficient system for effective post-harvest loss reduction, reduce greenhouse gas emissions, double the farmers’ income, and reduce the price fluctuation of food commodities. In recent years, the scientific community has shown a growing interest in post-harvest technology, primarily because of its potential to offer energy efficiency, affordability, off-grid capabilities, and self-sustainability. The present study reviews various energy-efficient and renewable energy-integrated post-harvest techniques that are being explored today, including simultaneous cooling and drying techniques for the extended shelf life of agricultural produce.</p> Graphical Abstract <p></p>
