Why is the price of small solar panels more expensive?

The smaller the solar panel, why the more expensive it is? Most people would think that the price of a whole piece of solar cell is only a few dollars, why the smaller it is, the more expensive it is.

Solar panel are completely customized in size according to customer needs. First, we must sort out the cells, remove some of the poor appearance and poor parameters, and then go to the slicing room for cutting in the second step, no matter how many cells there are. As long as the machine is turned on, we have to bear the start-up fee. After cutting it, it is not completely cut off, but a few fractions of it will be manually broken to avoid short circuits and unnecessary waste. If you encounter some manual breaking, you have to return to the machine to perform laser cutting again. If the slice is smaller, you must be more careful when breaking the slice manually. A slice that is too small is more brittle and is particularly tolerant of breaking. Then you have to bear unnecessary losses at this time.
