The SunPower Performance 6 solar panel was designed to avoid the known vulnerabilities of conventional panels.

The biggest problem with conventional cells, both standard and half-cut, is the connection process they have between cells. This connection is made by means of metal tapes (called bus-bars) and welding. This, in the long run, is a critical and known problem, which triggers hot-spots.

The proposal of the Performance panels is precisely that they do not use connection tapes or welding between cells. In this way, the major problem of conventional panels is eliminated.
