6 FAQs about [Photovoltaic inverter anti-pid technology]

How can PV inverters reduce PID?

At the system level, apply power electronic converter technology to reduce PID (Luo et al., 2016). Based on their topologies, PV inverters are broadly classified into two types: transformer-based inverters and transformerless inverters (Kerekes et al., 2011).

What is potential induced degradation (PID) of photovoltaic (PV) modules?

Author to whom correspondence should be addressed. The potential-induced degradation (PID) of photovoltaic (PV) modules is one of the most extreme types of degradation in PV modules, where PID-affected modules can result in an almost 25% power reduction. Understanding how module defects impact PID is key to reducing the issue.

Can an anti-PID inverter prevent PID?

The results of this study confirm that an anti-PID inverter is capable of preventing PID and, to some degree, other malfunctions in the PV module’s performance (e.g., leakage of current or degradation in EVA [25, 26, 27, 28, 29]). As a result, it can provide an alternative solution to hotspot recovery.

Are micro-inverters a good option for PID suppression?

In PV industry, micro-inverters are also gaining popularity recently. These inverters are installed on each module. However, the driving force for PID suppression in this field is weak due to low PV voltage in the range of 30–40 V (Ikkurti and Saha, 2015).

Can a PID Suppression Unit be used for photovoltaic module degradation?

Potential induced degradation (PID) is regarded as one of leading causes of photovoltaic (PV) module degradation. A PID suppression method is proposed in this paper, in which a PID suppression unit is added between DC negative bus and ground.

How to prevent PID in solar cells?

However, this coating is not a permanent solution and cannot prevent cracks and structural defects that lead to PID in solar cells. An alternative approach is to integrate the PV string with an anti-PID inverter [11, 12]. This inverter helps prevent current leakage in defective PV modules by directing it to the ground in the circuitry .
