Solar Cells - What is the Difference between A, B and C grade cells?
A, B, and C grade solar cells refer to the quality or efficiency of the cells.
- A grade cells are the highest quality with the highest efficiency and lowest defect rate. Typicall they will be blemish free and have the higest power output available.
- B grade cells have a slightly lower efficiency and higher defect rate than A grade cells. Typically they will have the same power output as A Grade cells , but have visible defects.
- C grade cells have the lowest efficiency and highest defect rate, and are often used for lower-power applications or for experimentation. Typically they will have low power output and visual defects.
