Question:

Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?

Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?

Answer:

We seldom see poly solar cell with the size of 152, because that is not really good to use.
The poly solar cell which is 156mm is not necessary high technology-based than the others. In fact, it's less efficient than the others.
We used the poly solar cell which is the 125mm size, which is good enough for our usage in the lab.
Most of the popular products in the market is 125mm or 156mm, because the 152mm is not really practically useful in the market.
To make is simple first, the numbers you saw such as 125mm, 156mm, 152mm, refers to the diameter of the silicon wafer.
