Frequently Asked Questions

Q1: What does Black on Black mean?

This indicates that the panel has a black anodized aluminum frame and a black backsheet behind the solar cells. This creates a uniform dark appearance that looks great on any roof.

Q2: How does the half-cell technology work?

By cutting traditional solar cells in half, the panel reduces internal electrical resistance. This allows the module to operate at cooler temperatures and significantly improves its performance when partially shaded.

Q3: Will this panel work with microinverters?

Yes. With an Open Circuit Voltage of 37.21V, this module is perfectly suited for use with modern microinverters like the Enphase IQ8 series.

Q4: Can these panels handle extreme weather?

Absolutely. The sturdy 30mm aluminum frame and thick tempered glass are certified for a maximum snow load of 5400 Pa and a wind load of 2400 Pa.

Q5: What is the warranty coverage?

Alexus provides a 25-year product warranty against manufacturing defects and a 25-year linear power warranty, ensuring the panel will retain high electricity production for decades.
