"This briefing reflects on the adaptation of the Innovation Histories method for our research project on the uptake of solar home systems (SHSs) in Kenya. It provides an overview of the method itself, how we adapted it to fit with the aims and theoretical perspectives of our research, and it reflects on our practical experiences of this process, including how we might do it differently in future. Our aim is to provide a practical point of reference for other researchers considering applying this method, particularly in the context of policy-oriented research."
