Factors Hindering Solar Photovoltaic System Implementation in Buildings and Infrastructure Projects: Analysis through a Multiple Linear Regression Model and Rule-Based Decision Support System

Energy plays a predominant role in the development of society. With advancements technology and growth society (buildings infrastructures), demand for energy is rapidly increasing. Developing countries typically rely on import fossil fuels capital investments infrastructure to meet their needs. The execution solar PV projects developing currently not being implemented promisingly. Therefore, determination critical success factors hindering implementation need hour. aim this study determine that hinder through use multiple linear regression model (MLRM) rule-based decision support system (RBDSS). Seven categories were identified detailed literature review interviews with experts. Four hundred twenty-nine complete responses collected total questionnaire, they analyzed using relative importance indexing (RII) MLRM RBDSS approaches. A comparison was carried out against both methodologies most barriers projects. findings regarding approach showed top seven economic conditions, encouraging policies, technological knowledge, organizational support, social awareness, market stability, miscellaneous aspects. Similarly, results application will help stakeholders making timely decisions corrections during phase, providing systematic way performance
