PV power station can easily affected by external environment, such as dust, dirt, snow, shadow occlusion on component surface are all likely to cause Buckets effect, which reduces power generation and service life of PV power station. So it’s important to quickly diagnose Buckets effect.
SOFARSOLAR inverter with I-V curve scan function can help you solve this problem.
1,Measurement of serial open circuit voltage (Voc), short circuit current (Isc) and polarity.
2,Provide measurement of maximum power point voltage (Vmpp), current (Impp) and peak power (Pmax).
3,Identify loss of PV module/array defect, shading, dust accumulation, temperature rise.Provide power attenuation, series/parallel adaption loss calculation.
