This paper presents a design verification for a small Stand-Alone Photovoltaic (SAPV) system under Malaysian tropical climate. The two design methods applied in this study were Mathematical Sizing (MS) model, which claimed to be one of the best sizing methods under Malaysian tropical climate and PVSYST commercial software. The comparison on the design results demonstrated that MS and PVSYST sizing methods have similarities but also differences. The study verified that both methods showed that increasing the system voltage, will reduce the required battery capacity. Significantly, the PVSYST software was found to oversize the battery bank and PV modules capacity required to meet the total energy required from load profile assessment. The differences encountered between the MS and PVSYST software were conceivably due to the different design parameters setting namely the minimum PV module temperature threshold, ambient temperature and battery parameters involved in the design calculation. This study has highlighted several technical understandings on designing SAPV system in both design methods, that can facilitate the PV system designers to evaluate the assumptions and mathematical models applied specifically in each sizing models.
