In this episode, William Brent speaks with Magda Moner and Sandor Szabo, leading researchers in rural development and renewable energy at the European Commission’s Joint Research Centre and co authors of the research paper Mapping of Affordability Levels for Photovoltaic (PV) Based Electricity Generation in the Solar Belt of Sub-Saharan Africa, East Asia, and South Asia. They shed some light on the impact of their research on affordability of solar PV grids in rural electrification and why it is a more sustainable option.
