Recent years have seen the increase in the shortages of electricity energy. Roof material, photovoltaic roof panels are among the emerging roofing techniques that are being adopted particularly in developed countries like China, America and Jordan. Despite the remarkable research about the benefits of photovoltaic roof panels, the adoption of this technology is still low and the literature that discusses the factors influencing their adoption is limited. It was on this background that this research investigated the factors that influence the adoption of photovoltaic roof panels as an alternative for reducing the consumption of electricity energy and address the electricity energy shortages. Qualitative data were collected from ten contractors drawn from a single case country of Zambia. The findings of this research identified both the internal and externa factors that influence the adoption of photovoltaic roof panels as a solution for the widespread electricity energy shortages. These factors included policy, economics, social, technology, awareness, attitude, availability, affordability, accessibility and self-efficacy. The findings inform policy makers on how to formulate policies that favour the implementation of photovoltaic roof panels. Furthermore, the findings of this research impact on the environment by suggesting photovoltaic roof panels as an alternative for zero-energy buildings as well as promoting an environment with reduced carbon.
