Towards Net-Zero Energy Houses: Optimizing the Size of Photovoltaic Systems Researchers develop a framework to easily determine the optimal size of solar panels and batteries needed in residential neighborhoods.

A new mathematical framework makes it simple to determine the optimal sizing for solar panels and batteries in households, report scientists at Tokyo Tech. By formulating a novel optimization problem and applying transformations to make it tractable, the proposed approach can quickly calculate the photovoltaic systems needed to turn homes into net-zero energy houses.

Residential buildings account for a large percentage of global energy consumption, and many countries around the world...
