Solar panels are mainly divided into A, B, C grade, the quality of A grade is the best, B grade is slightly inferior, is not in line with the quality standards of A grade, but still can be used in the PV module of the solar energy components. The quality of B grade solar panels is slightly defective, such as some cracks, color difference, etc. These defects will affect the performance and efficiency of its use.
These three kinds of solar panels are all made of cells, glass and back panel. Due to the different grade, their application are also different from each other.
A Grade solar panel: mainly used in ground power station, distributed power station, household system, etc., more than 25 years of life.
B Grade solar panel: mainly used in street lamps, off-grid systems, battery cars, etc., with a life of 5 years. This kind of component is the downgraded component of A grade or produced with B grade material.
C Grade solar panel: mostly used in underdeveloped areas, which is lack of electricity, such as some remote areas, the Middle East, South Africa, Afghanistan, etc.. While the life expectancy is unknown. So the C Grade solar panel is the most unstable panel among these three.
In terms of price, grade B solar panels are generally cheaper than grade A. The materials used and the cost of the panels will be cheaper than grade A ones. Many merchants in order to reduce production costs, they tend to use B-grade cells to produce, to provide customers with more affordable photovoltaic modules.
In terms of lifespan, although B grade solar panels are of slightly lower quality than A grade panels and have certain defects, it does not affect its ability to generate electricity as usual. However, the efficiency of using B grade solar panels is bound to be lower than that of using A grade solar panels, therefore, the lifespan of B grade solar panels will be shorter than that of A grade ones, which also means that the service life of B grade solar panels is longer than that of A grade ones.
In summary, we can come across that the use of B grade solar panels can reduce production costs, provide customers with more affordable prices, allow more customers to contact and use solar panels, and make the use of solar panels more routine. But at the same time, the B grade solar panels itself has the defects and quality will still affect the efficiency and performance in the process of use, so when communicating and cooperating with customers, we should consult the actual needs of customers, combined with the cost of production, to ensure that the use of solar panels and programs to meet the exact standards of customers.
