They possess a long-term degradation rate that is relatively low. Over the years, solar panels experience a gradual decrease in performance, known as degradation. However, modern technologies have significantly reduced this long-term degradation rate. Panels with a low degradation rate can maintain a relatively high level of performance over a long period, ensuring a consistent energy supply and a better return on investment.

The backsheet of PV module may have a fire-retardant property. This is an important safety feature, especially in applications where the panels are installed in close proximity to buildings or other structures. The fire-retardant backsheet can help to prevent the spread of fire in case of an emergency.

The manufacturing process of PV module often involves a step of wafer cleaning. High-purity solvents and cleaning agents are used to remove any impurities, particles, or residues from the surface of the silicon wafers. This is crucial as even the slightest contamination can affect the performance and efficiency of the solar cells. The cleaning process is carried out in a controlled environment to prevent recontamination.
The cost of training and certification for installing solar panels can range from a few hundred dollars for basic online courses to several thousand dollars for comprehensive in-person training programs. Certification is important as it ensures that installers have the necessary knowledge and skills to install the panels safely and correctly. The cost of training and certification is often borne by the installer or the company they work for and is factored into the overall cost of the installation service.
