Every solar sales rep will pitch you "premium panels." Here are the only four brands actually worth considering for a residential install in 2026, ranked.

What each one is best at
QCells Q.Peak Duo ML-G11+ — The default I recommend for ~70% of homeowners. Made in Georgia, qualifies for the 10% domestic content tax credit bonus (extra $2,240 off an 8kW system). Efficiency is slightly behind REC but the price-to-warranty ratio is best-in-class. Sunnova and Sunrun both default to this panel.
REC Alpha Pure-R 410W — The premium pick. Highest efficiency in this list (21.7%) means more power from less roof space — matters if your roof is small. 92% linear power warranty is industry-leading (panels still produce 92% of original rating at year 25). Costs $0.20/W more, so ~$1,600 more on an 8kW system. Worth it ONLY if your roof is small enough that you need every watt per square foot.
Silfab SIL-410 BG — The "I want made-in-North-America but don't want to pay REC prices" pick. Solid specs, qualifies for domestic content bonus. Slightly less brand recognition than QCells but functionally similar performance.
Trina Vertex S+ 415W — The value pick. Highest watt output (415W) at the lowest price. Chinese manufactured, so no domestic content bonus. Trina is one of the world's largest solar manufacturers — financial stability is strong. Best for budget-conscious homeowners willing to skip the bonus.
What I'd actually pick
For an average FL homeowner with adequate roof space:
QCells Q.Peak Duo ML-G11+ 410W wins on the total cost-of-ownership math. You get:
- Solid efficiency (20.6%)
- Domestic content tax credit bonus eligibility (+$2,240 savings on 8kW system)
- US assembly (Georgia plant)
- Strong manufacturer warranty backing
- Industry-standard pricing
For a homeowner with limited roof space who needs maximum density: REC Alpha.
For a homeowner on tight budget who doesn't need the bonus: Trina.
Panels to AVOID in 2026
-
Generic "Tier 2" panels with no brand-name. If a quote says "premium 400W panels" without naming the brand, walk away.
-
SunPower / Maxeon. SunPower's Maxeon subsidiary is in financial distress as of 2025. Warranty backing is questionable.
-
First Solar thin-film panels. Great for utility-scale, lower efficiency for residential.
-
Any panel below 380W in a 2026 install. Panel technology has progressed. Anything older is dated inventory the installer is trying to dump.
How to tell what panels you're actually getting
Demand the exact model number in your contract. Not "400W panels" — specifically "QCells Q.Peak Duo ML-G11+ 410W" with the model number. If the installer won't commit to the specific model in writing, you're being set up for a panel substitution.
When the install happens, check the back of one panel during installation. Manufacturer + model is stamped there. Make sure it matches your contract.
What I'd do
Send me your quote and I'll tell you whether the panels listed are fair value, premium upcharge, or generic substitute waiting to happen.
