Abstract
A node within a wireless network is powered by a solar hybrid battery system. The solar hybrid battery system includes a solar panel, a primary cell, and a secondary cell. The secondary cell includes only enough power storage to be capable of powering the node during the longest daily interval of darkness in the region where the node is deployed. The solar panel is sized relative to the secondary cell to be capable of fully recharging the secondary cell during the shortest daily interval of daylight in the region where the node is deployed, even under conditions of limited solar irradiance (e.g. due to clouds). The primary cell can charge the secondary battery if the node is shelved or malfunctioning to prevent the secondary cell from becoming overly depleted. The primary cell can also provide the node with additional power during times of peak demand or to perform status reports.
