Purpose: Using renewables has been considered as one of the reliable solutions for building applications to achieve zero-energy building goals. Photovoltaic (PV) systems are a highly applicated option because of their ease of installation and cost-effectiveness. Effective evaluation methods and tools are needed to determine the building energy efficiency rate and acceptable zero-energy building certifications. This study aims to examine the PV generation analysis method of the evaluation tool for advancing the PV system evaluation method. Method: This study considers different PV calculation methods (e.g., ECO2, simple, one-diode, and PVWatts) and investigates the calculation characteristics of each approach to compare with the evaluation tool. Among the PV calculation methods, the most used one-diode model is adopted to compare the details of PV input variables and thus evaluate power generation performance under various simulation conditions for the improvement potential of the current evaluation tool. Result: Various input parameter conditions need to be reflected to improve the PV system analysis method of the evaluation tool. The evaluation tool should adopt the installation azimuth conditions for analysis and application scalability. In addition, the subdivision of the inclination is suggested as an improvement measure for further analysis options. The expansion of the installation azimuth can affect the utilization of the roof and elevation on the north side. The subdivision of the inclination enables a reliable zero-energy certification grade to improve through the calculation of more precise energy self-sufficiency rate evaluation results in a detailed manner. |
