Abstract

The utilization of solar energy in Indonesia remains relatively low despite its high potential in terms of solar irradiation and geographical advantage. One of the main challenges in photovoltaic (PV) systems, especially in tropical climates, is the decline in performance caused by high operating temperatures. Unlike previous studies that primarily focused on passive cooling methods or basic active cooling without intelligent control, this research introduces a cross-mounted water pipe cooling system integrated with a Fuzzy Inference System (FIS) for dynamic water flow regulation, enabling optimal temperature control and dual-output (electrical and thermal) efficiency. Experimental testing on two 100 Wp monocrystalline solar panels—one with cooling and one without—under identical conditions revealed that the cooled panel achieved an average maximum power of 85.2 W, compared to 43.6 W for the non-cooled panel, with efficiency improvements of up to 7.4% over the observation period. A linear regression model was developed to predict PV performance under varying temperature conditions, demonstrating a slower decline in efficiency and more stable power output in the cooled system. The proposed hybrid PV/T configuration effectively dissipates heat while simultaneously recovering thermal energy, thus enhancing total energy utilization. These results highlight the system’s capability to mitigate thermal degradation, extend module lifespan, and promote sustainable renewable energy adoption in tropical regions. The integration of intelligent control with thermal management presents a scalable and energy-efficient approach for future photovoltaic applications.

Abstract

The transition to renewable energy is a global effort to combat climate change and provide sustainable energy. One of the technologies that is developing is the use of solar power plants (SPP), which are capable of providing clean and environmentally friendly energy. This study aims to analyse the performance of the PLTS system in operating two types of electric motors, namely DC (Direct Current) motors and AC (Alternating Current) motors, with the assistance of an inverter. The experiment was conducted using an off-grid PV system with batteries and a solar charge controller (SCC). Measurements were taken of the voltage, current, and power of each system. The results showed that the AC motor produced greater power (86.3 W) after passing through the inverter compared to the DC motor, which only produced 18.4 W. This study provides insights into selecting the appropriate motor type for solar power systems to ensure efficiency and support SDG 7 targets.
