Cellphone-linked portable device for real-time solar module characterization

Scientists in Colombia have conceived a new portable electronic device for on-site measurements of the I-V and P-V curves of photovoltaic panels. The novel system considers solar radiation, ambient temperature, electric current, and voltage signals from a PV panel via a cellphone through a mobile application. A research group from Colombia has conceived a new portable electronic device that enables on-site measurements of the I-V and P-V curves of photovoltaic panels and can reportedly compete with similar but more expensive and difficult-to-handle technologies that are available in the market. ...
