PID issues in thin-film PV plants

Nowadays, there is a worldwide production capacity of about 5GW of thin-film module technology. In total, an estimated cumulative installed capacity of 15 to 24GW exists (5-8% of 300GW installed worldwide in 2016). But how serious is the threat of PID in this thin-film fleet?

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.

Predicting moisture-induced degradation of flexible PV modules in the field

A critical failure mechanism for PV modules is the degradation in performance as a result of exposure to temperature and humidity. In the case of flexible PV modules, moisture-induced damage becomes a greater concern, since the moisture resistance of barriers and polymer packaging is expected to be lower than that for conventional glass–glass PV products. The work presented here is aimed at establishing, through the use of accelerated testing, the field lifetime of flexible PV modules with regard to moisture-induced degradation.
