Manufacturing organisations should embrace green technology innovation that strengthens their sustainable performance in a continuous dynamic market to promote coordinated natural environmental, social, and economic development. Pertaining to this objective, several studies have been performed to enhance the adoption of green technology innovation and sustainability performance. Nonetheless, the existing literature is insufficient to clearly indicate whether green technology innovation enhances sustainability performance in the Malaysian Solar Photovoltaic (PV) industry. Therefore, this study aims to construct a conceptual framework by documenting the relationship between green technology innovation and sustainability performance in the Malaysian PV industry. To empirically validate this relationship, this study proposed the collection of data through primary sources from the Malaysian manufacturing solar PV industry, incorporating a 5-point Likert scale. Regarding the data analysis, Partial Least Square-Structural Equation Modelling (PLS-SEM) is proposed to investigate relationships between constructs and latent variables. With theoretical support, the proposed results indicate that green technology innovation enhances sustainability performance, specifically in Malaysian manufacturing solar PV organisations. In practice, this paper helps policymakers to design comprehensive policies and systematic guidelines for strengthening sustainability performance through the adoption of green technology innovation, specifically in the solar PV manufacturing industry. Scholarly, it will also enrich the existing body of knowledge on green technology innovation and its impact on sustainability performance in the Malaysian manufacturing solar PV industry.
