Common questions
What people ask about the 415W Hi-MO 6 Explorer Solar Panel
Will the LONGi 415W Hi-MO 6 Explorer Solar Panel qualify for the federal solar tax credit?
FEOC compliance for LONGi 415W Hi-MO 6 Explorer Solar Panel hasn't been independently confirmed by us. Section 25D — the residential ITC — expired Jan 1, 2026, so for cash purchases the question is moot. For leases or TPO, ask the installer to provide manufacturer FEOC documentation before signing.
What does the warranty actually cover?
LONGi 415W Hi-MO 6 Explorer Solar Panel carries a 15-year product warranty (defects in materials and workmanship) and a 25-year linear performance warranty. The product warranty matters most: panels in residential service rarely degrade past spec, but they do occasionally fail electrically. A short product warranty (under 15 years) is the bigger flag than a short performance warranty.
How does the temperature coefficient affect real-world output?
Panel cells in summer regularly run 25–35°C above ambient air temperature, and every panel loses some output as temperature rises. Panels with Pmax temperature coefficients closer to -0.25%/°C lose less power in heat than panels at -0.35%/°C — meaningful in hot climates like TX or AZ.
Is this panel bifacial?
No — LONGi 415W Hi-MO 6 Explorer Solar Panel is monofacial (front-side only). Bifacial panels capture diffuse light on the back side too, but the realistic gain on a typical residential roof is only 2–5% in practice. It's not a feature most homeowners notice the absence of.
