Abstract: The present invention relates to a fault detection system and method of a photovoltaic module and string. The fault detection system of a photovoltaic module and string includes a measurement input unit receiving a current power generation performance measurement value of the photovoltaic module and string from the outside, an estimation calculating unit calculating a power generation performance estimation value of the photovoltaic module and string based on input current environmental conditions, and a fault determining unit determining whether the photovoltaic module and string have a fault by comparing and analyzing the power generation performance measurement value from the measurement input unit and the power generation performance estimation value from the estimation calculating unit, wherein the photovoltaic module is configured as a double-sided or single-sided photovoltaic module.
