Common questions
What people ask about the 100W Bifacial Solar Panel
Will the Eco-Worthy 100W Bifacial Solar Panel qualify for the federal solar tax credit?
FEOC compliance for Eco-Worthy 100W Bifacial 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?
Eco-Worthy 100W Bifacial Solar Panel has a Pmax temp coefficient of -0.35%/°C. In summer, panel cells regularly run 25–35°C above ambient — so a 35°C cell at peak sun will lose roughly 12.3% 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.
What's the realistic bifacial gain on a residential roof?
Eco-Worthy 100W Bifacial Solar Panel is bifacial with a rated gain up to +15%. Realistic gain on a residential roof is much lower than the spec — typically 2–5% — because most roofs sit close to the rafters with dark underlayment that absorbs (rather than reflects) light. Bifacial pays back better on ground mounts over white gravel or on light-colored roofing. On a standard composition-shingle roof, treat the bifacial gain as a small bonus, not a planning assumption.
