Abstract

This study investigates the technical and cost-effective performance of options renewable energy sources to develop a green off-grid telecommunication tower to replace diesel generators in Malaysia. For this purpose, the solar, wind, pico-hydro energy, along with diesel generators, were examined to compare. In addition, the modeling of hybrid powering systems was conducted using hybrid optimization model for energy (HOMER) simulation based on techno-economic analysis to determine the optimal economically feasible system. The optimization findings showed that the hybrid high-efficiency fixed photovoltaic (PV) system with battery followed by 2 kW pico-hydropower and battery are the optimal configurations for powering off-grid telecommunication towers in Malaysia with the lowest net present cost (NPC) and cost of energy (COE). These costs of NPC and COE are more down than diesel generator costs with battery by 17.45%, 16.45%, 15.9%, and 15.5%, respectively. Furthermore, the economic evaluation of the high-efficiency solar fixed PV panels system annual cash flow compared to the diesel generator with the battery system indicated a ten-year payback period.

Abstract

This paper is performed to investigate the performance of ‎dual-axis solar tracking system with maximum light detection for off-grid telecommunication towers under weather conditions in Malaysia. The studied system consists of High-efficiency heterojunction intrinsic thin (HIT) film solar modules ‎coupled with state-of-the-art dual-axis maximum light detection (MLD) solar ‎tracking system. The ‎investigation method is based on the analyzed the daily actual data record for both the average power output of ‎the photovoltaic system and the ‎state of charge of batteries in four months ‎under different weather conditions as a function of time. Based on the results obtained ‎the use of HIT solar modules with MLD dual ‎axis solar tracking system has high performance effective under ‎Malaysian weather.‎ The study also presented the detailed investigated system description.
