How to deal with bubbles on the surface of photovoltaic panels
Besides, this method can provide an overview of the PV system’s condition. Some visible defects in PV modules are bubbles, delamination, yellowing, browning, bending, breakage, burning, oxidization, scratches; broken or cracked cells, corrosion, discoloring, anti-reflection and misaligning (see Fig. 1). .

According to Munoz et al. (2011), the bubbles impede the heat dissipation of the cells, increase the overheating, reduce the lifespan of the module, decrease the solar irradiance absorption, and increase the reflection of sunlight on the photovoltaic module.
As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up. Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites.
Below is a list of common problems with PV backplates that Maysun Solar has compiled for you. 1. Yellowing. When laminating solar modules, two layers of adhesive film are used to bond the solar cells to the glass and backsheet as a unit. One of the two layers of adhesive film is generally required to block short-wave UV light.
You can detect the start of delamination by bubbles and creases on the plastic rear surface. Some owners try using duct tape and sealant to slow the process down, but such a panel isn't going to last long.
