Common questions
What people ask about the 385W Monocrystalline Solar Panel
Will the Phono Solar 385W Monocrystalline Solar Panel qualify for the federal solar tax credit?
FEOC compliance for Phono Solar 385W Monocrystalline 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?
Warranty terms for this specific module are not yet in our verified data set. Always confirm both the product (defects/workmanship) and the linear performance terms with the installer or the published datasheet before purchase.
How does the temperature coefficient affect real-world output?
Phono Solar 385W Monocrystalline Solar Panel has a Pmax temp coefficient of -0.417%/°C. In summer, panel cells regularly run 25–35°C above ambient — so a 35°C cell at peak sun will lose roughly 14.6% of nameplate power. Panels with coefficients closer to -0.25%/°C (better) lose less in heat than panels at -0.35%/°C (worse). For hot-climate installs (TX, AZ) this gap is real annual production.
Is this panel bifacial?
No — Phono Solar 385W Monocrystalline 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.
