Common Solar Panel Issues

In a solar panel, we can come across many issues. You can calculate solar panel efficiency to note degradation and performance lag. However, the thing that matters is solving such issues. Yet let us discuss some of these issues.

Issues in Inverters

We all know that inverters are an essential element of a PV System. Yet, they play an important role in converting the Direct current. However, homes can only run on Alternating current. Thus, it is necessary to have stable inverters. So, we need to check the inverters or get some expert services.

Hotspots and Microcracks

Solar system works with the help of solar cells. But, these cells need to generate electric current. Yet, there comes the role of generating electric current. However, electric current flows by these cells. Therefore, with a minor fault, we can observe patches. However, these happen due to hotspots and microcracks. Due to such fault, resistance increases. Thus, with this approach system heats up. Here, the hotspots are caused by heat. Such elements are not visible to the naked eye. But these are harmful as they can burn the cells. So, we need to look after the microcracks and hotspots.

Potential Induced Degradation

The process of panel degradation is said to be potential-induced degradation. Here, we observe the variety of conditions that do so. However, these consist of high temperature, voltage, and humidity. In other words, this process is said to be a voltage leak. It happens from cells to the frame of the solar panel. However, this process overall reduces the power output.


When the layer of organic and inorganic contaminants gather on the surface of PV Modules then this process is called soiling. Yet, this process is damaging for panels as it affects the performance of PV Panels. But, the latest PV Systems easily monitor this process. All we need are the sensors to detect it.

Bird droppings and Pest damage

This factor may not seem a major thing but it can be problematic at times. For example, you can experience the destruction of Panels coating. This is because the bird droppings are acidic in nature. However, pest damage can also break the solar cells. As panels are installed on certain heights so such a factor is obvious to happen. 

Wiring Issues

For any solar system, the thing that we experience the most is the connections. Here, we need to connect panels, inverters, batteries, and other important equipment. Moreover, there should be a proper connection for such parts. It should be done properly as it can affect the performance of a PV System.

Impact of Weather

Solar panels can be damaged by hail, high winds, and other extreme weather events. Therefore, we need to check the panels accordingly. Moreover, the weather conditions vary for different locations. So, we need to manage the panels accordingly.
