About How to deal with idle photovoltaic panels
PID is related to the negative potential that each PV module can deal with when working in normal operative conditions. PV modules are connected in series to create a string and the overall string voltage is distributed among all the single PV modules. How this voltage distribution happens depends on the inverter type.
A PV module is made by several components (Figure 1), but the ones that play an important role in this discussion are the solar cell, the encapsulant material (EVA in most of the.
To determine if a PV module is affected by PID, it’s possible to perform an I-V curve test or an electroluminescence test. Note that the electroluminescence test only indicates if some cells are.
In the case of new PV plants, it’s important to focus attention on the type of materials and the design choice of each module before making any purchases. Design choices that can affect the occurrence of PID are mainly related to.
Luckily, in most cases, the PID effect is reversible. However, if it has existed for a prolonged time without measures taken to fix the problem, it will.Here are some quick tips:Use a soft brush or clothClean early morning or late afternoonBe gentle to avoid damaging the panels.

PID reduces the performance of the PV modules due to a reduction in the shunt resistance of the electrical model (Figure 4). This corresponds to an increase in the leakage current, resulting in a decrease of the output current (and so, total output capacity) and affects the I-V curve as shown in Figure 5. Figure 4.
Maysun’s HJT (Heterojunction with Intrinsic Thin layer) solar panels effectively prevent Potential Induced Degradation (PID) through the strategic use of a Transparent Conductive Oxide (TCO) film layer on the glass surface. This TCO layer prevents charge polarization, structurally averting PID degradation.
One of the most common solutions for residential and small business customers is net metering. Users keep their utility connections, and their system feeds unused energy back into the grid. The utility company offers credits that the customer can use to cover the cost of electricity from the grid after dark.
PID can significantly reduce the power output of a photovoltaic (PV) module within the first year of operation, with power losses at the module level as high as 70% in the first 18 months. These module level losses can progress rapidly and become so severe that they affect the performance of an entire system.
As the photovoltaic (PV) industry continues to evolve, advancements in How to deal with idle photovoltaic panels have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [How to deal with idle photovoltaic panels]
How to reduce the risk of PID in photovoltaic systems?
Mitigation actions, including selecting PID-resistant modules, proper installation, and environmental management, can significantly reduce the risk and effects of PID in photovoltaic systems. What is PID? Potential-induced degradation (PID) is a phenomenon that adversely affects the performance of PV modules over time.
How does PID affect the performance of solar panels?
PID reduces the performance of solar panels by decreasing the shunt resistance of the electrical model (see Figure 1). This corresponds to an increase in leakage current, resulting in a reduction of output current (and thus, total output capacity), and it affects the I-V curve as illustrated in Figure 2.
How do Maysun solar panels prevent PID degradation?
Maysun’s HJT (Heterojunction with Intrinsic Thin layer) solar panels effectively prevent Potential Induced Degradation (PID) through the strategic use of a Transparent Conductive Oxide (TCO) film layer on the glass surface. This TCO layer prevents charge polarization, structurally averting PID degradation.
How does PID affect PV modules?
The effects of PID on PV modules can be profound. As the negative voltage accumulates, it can lead to power loss, reducing the overall efficiency of the module. This translates to decreased energy production and potential financial losses for PV system owners. PID’s impact on PV modules’ efficiency is sometimes reversible.
Will a solar panel be affected by light induced degradation?
A solid understanding of the solar panel circuitry, photovoltaic device design, and thermal resistance is crucial to identify whether a panel will be affected by such degradation or not. The term “LID” (Light Induced Degradation) is commonly used in solar panel installation literature and industry trade journals as a synonym for thermal shock.
Why should you take precautions when installing a solar panel?
Taking every precaution will ensure minimal solar panel degradation rates and a longer lifespan for PV systems. The higher the degradation rate, the higher energy losses the PV system will experience throughout its lifetime.
