Can I use a Canadian Solar 310W panel with 3 Busbars on the same string as a Canadian Solar 310W panel with 4 Busbars?
The 4 bus cells are slightly more efficient, however, there is no issue mixing 3 & 4 busbar modules in the same string. The key is to match voltage or amperage, depending on the stringing configuration used. More on that in this article.
