The invention relates to the technical field of photovoltaic testing, in particular to a photovoltaic line loss testing system and method.The photovoltaic line loss testing system comprises a first cable and a second cable, a plurality of collectors are arranged between the first cable and the second cable in parallel, and the collectors are arranged on the first cable and the second cable at intervals; one ends of the plurality of collectors are respectively connected with the first cable and the second cable through the voltage sampling clamp; the other ends of the plurality of collectors are connected with a second cable through a current sampling clamp; and the joints of the plurality of collectors and the first cable and the second cable are fixedly sleeved by cable protection sleeves. According to the photovoltaic line loss test system and method, the test system can measure cable line loss on line in real time and monitor the change trend of all-day line loss; the measurement precision is ensured by me
