Using shunts to spot PV module degradation
Scientists in Ireland investigated the effect of shunt resistance on a PV cell’s electrical performance. The group says its finding could potentially lead to the development of models for early detection of various forms of cell degradation, allowing for intervention to repair or replace components before major power losses occur.
Online algorithm to estimate open-circuit voltage in PV systems
The new technique, proposed by researchers in Pakistan, is claimed to estimate the voltage, current and temperature of a PV system without interrupting the power flow to load.
