The hidden cause of module degradation and how to avoid it in your future deployments

SPONSORED: Falling system prices have been a key driver of PV's recent growth and competitiveness, but upfront costs are only one part of the equation for long-term profitability within the solar power industry. Maximising any given system’s cumulative power output over its lifetime is critical to lowering the levelised cost of electricity (LCOE) and maximising investment returns.

Detecting cell cracks and other PV module failures with UV fluorescence

Module failure | Defective modules causing power losses in PV systems need to be easily detected with a rapid and cost-effective inspection method. UV fluorescence of module encapsulation polymers is used for the fast detection of module failures under daylight conditions without disconnection, allowing the inspection of up to 200 modules in an hour during daytime

After experiencing their own problems with potential induced degradation (PID), Belgium-based Edison Energy took matters into its own hands and developed the Pidbull solution in partnership with imec. Now it sells Pidbull to anyone experiencing issues with PID. As managing director Davy Verheyden explains, it is a problem solar asset owners cannot afford to ignore.

Impact of installation handling on cell cracks and power loss of PV modules

PV modules are subjected to various loads during installation handling. Research teams from the Institute for Solar Energy Research Hamelin (ISFH) and Hanwha Q CELLS attended the installations of PV modules in order to develop various test sequences for quantifying the effects of handling loads on the modules. As a result of these observations, lab tests have been designed to evaluate the impact of module-handling loads on cell cracking in the modules. Some rules for module handling are subsequently proposed.
