A solar panel can be attached to the solar panel connector, providing extra energy to the Plug & Sense! and
extending the EBM life. Furthermore, if the charging period occurs while the solar panel is providing energy, the
EBM will only provide the necessary current to fulfill the demand of the Plug & Sense! node. If the solar panel is
able to provide all the current demand, the EBM will not contribute during the charging process. This way, the
system does not waste energy from the solar panel and, at the same time, it enlarges the EBM battery lifetime.
