How is a 54-cell module different 60-cell or 72-cell module?
Is it just the voltage? Why do the manufacturers choose to produce different number of cells?
Comments
A solar cell (mono or polycrystalline Si) puts out about .5 VDC. Modules are assembled as strings of these cells in series to reach a particular volatage. As manufacturing tolerances are improved, modules are growing in size under the assumption that the larger they are, the more econmical they are for large installations.
A 60 Cell module puts out about 30VDC at maximum power and a 72 Cell module puts out about 36VDC at maximum power.
