Identifying Hidden Resources in Solar Home Systems as the Basis for Bottom-Up Grids
Presenter: Hannes Kirchhoff, (Microenergy Research Group)
Rapporteur: Austin Cappon
Overview
| In the context of the modern energy access challenge, one new pathway towards electrification is to make use of hidden resources already in the field through small microgrids. In particular, this paper analyses the amount of energy that is dumped in a medium sized (65 Wp) solar home system (SHS) located in Bangladesh. The SHS is modeled using synthetic load curves and a sophisticated battery model that accounts for battery ageing. The simulation shows that more than 30% of the energy generated by the SHS remains unused[1]. |

Issues Presented
► Please see the presentation.
Q & A
1. Has the battery degradation model been verified?
- Cannot simply say a certain SOH will translate to x number of years to run. It’s a mere model.
2. The demand assumption is a big piece, how did you arrive there?
- With care. We make conservative assumptions about the types of loads.
- Convinced that the 30% of additional power is realistic.
