Abstract

Malaysia demonstrates its commitment to alleviating the negative climate and energy issues through various initiatives. One of the latest initiatives is the amendment of the net-energy metering (NEM) scheme that takes effect from 2019. This paper presents the distribution of energy to the residential house that has a grid-connected solar photovoltaic (PV) system installed. The study quantifies the percentage of energy consumed from the PV system and the grid as well as the percentage of PV generated energy that is exported to the grid. On average, 38% of generated energy was used for self-consumption that contributed to 28% of the total consumption. Economic evaluation over a 25-year lifecycle of the PV system is also conducted shows that the simple payback period for NEM 2019 and NEM 2016 is 8 years and 20 years, respectively. The latest version of NEM shows a superior advantage compared to the previous one which may attract more investments in PV generation.

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.
