Abstract

This article presents a comprehensive Systematic Literature Review (SLR) of cutting-edge advancements in solar energy technology, mapping the paradigm shift from single-component efficiency to multi-functional system integration. Utilizing a data corpus from JREE and PLTS comprising high-repute publications from the 2023–2026 period, this study identifies five primary innovation clusters: (1) optimization of photovoltaic (PV) systems and perovskite solar cells; (2) integration of thermal energy storage utilizing Phase Change Materials (PCM); (3) hybrid solar drying applications for the agro-industrial sector; (4) desalination technologies based on interfacial evaporation; and (5) smart building implementation via data-driven control systems. In response to critical reviews, this article strengthens its methodological foundation by providing technical justification for selecting the data corpus, ensuring it is representative of global trends, and mitigating the limitations of abstract-based analysis through an in-depth examination of key studies. Specific focus is placed on the role of Artificial Intelligence (AI), as this review transitions from a descriptive narrative to a systematic analysis of the requirements for interpretable and robust models in system monitoring. The analytical results indicate that the synergy between advanced materials such as nanofluids and metamaterials—and multi-objective optimization algorithms is pivotal to achieving decarbonization targets. Overall, this review provides a roadmap for researchers in developing solar systems that are not only technically efficient but also economically viable and sustainable, supported by a comprehensive reference list that reinforces the reliability of this data synthesis.

Abstract

The performance of Solar Power Plants (PLTS) in tropical regions is significantly influenced by fluctuations in environmental parameters and system operational effectiveness. This study evaluates the performance of a 2 MWp grid-connected solar PV plant in Sumalata, Gorontalo, utilizing the Performance Ratio (PR) as the primary metric during the seasonal transition period (October–December 2025). Data were harvested from a SCADA monitoring system to analyze the correlation among energy yield, solar irradiation, and performance degradation. The results demonstrate monthly PR values of 75% (October), 74.2% (November), and 64.2% (December), with a mean period efficiency of 71.1%. The significant decline in PR during December is attributed to environmental factors, specifically increased cloud cover and humidity, as well as technical constraints such as module soiling accumulation and inverter operational disturbances. These findings underscore that, while the average performance remains within the operational benchmark (70%), adaptive Operation and Maintenance (O&M) strategies tailored to the humid tropical climate are essential to ensure long-term stability in system efficiency.

Abstract

PT. Sinar Kristal Nusantara currently only relies on driver experience in determining distribution routes without special studies, which causes delays in the delivery of crystal ice products due to irregular distribution flow. This study aims to determine the optimal distribution route with the shortest distance to make deliveries more efficient and timely. The methods used are Nearest Neighbor and Tabu Search algorithm. The process starts by classifying the initial route using Saving Matrix, then determining the optimal route through Nearest Neighbor and Tabu Search. The results showed that this method resulted in a total mileage of 31.05 km with a travel time of 37.26 minutes, more efficient than the current route which reached 63.90 km with a time of 75 minutes. Tabu Search proved to be a superior optimization method because it produced a shorter route than using Nearest Neighbor alone. In conclusion, the combination of Nearest Neighbor and Tabu Search can improve the efficiency of crystal ice distribution at PT. Sinar Kristal Nusantara.
