Photovoltaic generation and electric mobility are both disruptive technologies in the power and transport sectors raising several issues regarding power grids. Precisely, questions about synergistic potentials when combining these two technologies have attracted academics’ interest. Recent researches on this topic demonstrate that interactions between photovoltaic generation and electric mobility could decrease the overall burden on power grids, and empower one technology with the others speci cities.

Indeed, electric vehicles could use photovoltaic energy and bene fit from a low-cost and carbon-free electricity to charge. In return, photovoltaic systems would use the bi-directional exibility of electric vehicles battery to maximize their self-consumption. As these synergies operate, these technologies economic spillovers may improve, stimulating their joint deployment.

The objective of this paper is to develop a systematic framework in order to review the different underlying conditions for synergy as they have been studied in the literature. It appears that this synergy was driven by technical characteristics as well as economic aspects.

First, this synergy happens in middle-sized spatial confi guration (large workplace buildings and charging station) and less obviously at other scales and in situation of technologically diversi ed system. Second, if it was poorly studied in the literature, the economic context (cooperation level between stakeholders, regulation and policies..) of interactions between photovoltaic generation and electric mobility is crucial for a successful synergy. Finally, we identify several remaining issues about these conditions that further researches could investigate.
