Maxeon 7 Residential Solar Module
This is a national, editorial, whole-system estimate — not this specific module's price. This catalog's real, seller-observed prices (P3c) are per-module, in the low hundreds of dollars, because that is the only scope real retail sellers publish for individual panels. The two numbers describe different things and must never be shown as if they were the same figure.
24.1% efficient module with a 40-year warranty and the lowest degradation rate on the market.
Our take
Maxeon's back-contact cell architecture has led efficiency for years, and the 40-year warranty is unmatched. Whether that is worth the premium comes down to roof area: if your roof can fit all the panels you need, cost per watt wins and a mainstream module makes more sense. If your usable roof is small and you need every watt from it, this is where the money goes.
Best for
Small or shaded roofs where maximum output per square foot is the binding constraint.
Watch out for
With the 25D credit gone, the premium over a mainstream module is now fully out of pocket. Re-run the maths against a Qcells or Silfab array.
Compare against
Canadian Solar HiKu7 Solar Module
21.6-22.7% efficient module positioned on cost per watt rather than peak specification.
JA Solar DeepBlue 4.0 Pro (JAM54D41) Solar Module
22-22.8% efficient module with a notably shorter product warranty than every other panel in this catalog.
JinkoSolar Tiger Neo (JKM-N-54HL4R-BDB) Solar Module
21-22.5% efficient N-type module substituting for LG in this catalog, since LG exited solar panel manufacturing in June 2022.
Mission Solar MSX10 N-Type 108HC Solar Module
22-22.8% efficient module manufactured in San Antonio, Texas — the only US-manufactured panel in this catalog.
Before you buy this
Ask what the production estimate is based on — an actual shading analysis or a rule of thumb — and what export rate it assumes; net metering rules move the payback more than any panel spec. Confirm the quote isn't still claiming the 30% federal credit: it expired for anything placed in service after 31 December 2025. If financed, ask for the all-in cost including interest, not just the monthly payment.
