FAQ

Q: Does pairing Panasonic panels with a Panasonic battery offer any real advantage?

A: Mainly simplicity — one brand, one warranty contact, and systems designed to work together. Performance-wise, most quality panels pair fine with most quality batteries, so this is more about convenience than a technical requirement.

Q: How does Panasonic compare to REC on performance?

A: They're close competitors in the same premium HJT tier. REC edges out slightly on peak efficiency (22.6% vs 22.2%), while Panasonic often has an edge in brand recognition and buyer confidence given its consumer electronics history.

Q: Is Panasonic still manufacturing solar panels in the US?

A: No — EverVolt panels are manufactured overseas, so this line doesn't qualify for the domestic content tax credit bonus, unlike some Qcells models.
