Economic Analysis of Home Photovoltaics System: Extreme Weather Case Study

摘要

A case study of the electric usage and cost of residential households under severe weather conditions is presented in this article. Extremely hot weather in Texas led to a sharp increase in electric usage at the local power grid, which necessitated a corresponding increase in price. For the residential households installed with Home Photovoltaics (PV) System, the solar power could provide a strong support to keep the utility electricity cost from this price surge. Additionally, extra solar energy could help a neighboring household avoid most of the abnormal electricity price. Matlab simulation results also indicate that this electric energy interaction between neighbors can reduce the energy cost of the household with the Home PV System.
