Best Solar Panels
Written by HyreSolar Research Desk Primary-source research and fact checking
Quick answer
Best Solar Panels are ranked here on a published method using certified specifications and warranty terms, with no paid placement.
The ranking itself is not published yet. Before we put any panel above another, every figure behind it has to come from the California Energy Commission’s certified equipment list and the manufacturer’s own datasheet and warranty document, and our method has to clear an editorial sign-off.
Until then this page sets out exactly what we score and how, so you can apply the same test to the panels on your own quotes.
Cost side by side
Installed prices as other publishers state them, gross of incentives. Each range is the median published low to the median published high across at least 12 dated sources, retrieved October 21–22, 2026; the source rows sit on the linked cost page.
| Option | Published range | Sources |
|---|---|---|
| Installed price per watt (all panel brands) | $2.58/W–$3.36/W | 21 dated |
No 30% federal credit is subtracted: Section 25D ended for expenditures after December 31, 2025.
Why there is no ranked list on this page yet
Most "best solar panels" lists rank products their authors have never installed, measured or read the warranty for, and many are paid for by the brands they rank.
Google’s guidance on product reviews asks for evidence of first-hand use; we have not run hands-on trials of residential modules, so we will not imply that we have.
What we can do honestly is compare panels on independently certified figures and published contract terms.
That produces a narrower kind of ranking: it can tell you which panel has the stronger warranty and the better certified temperature performance, but not which one an installer finds easier to work with or which brand will still exist in 25 years.
We say which of those questions the method answers and which it does not.
The selection method: what we score and where it comes from
| Criterion | Field we read | Primary source | Why it matters |
|---|---|---|---|
| Eligibility | Listed and in good standing | CEC Solar Equipment List (PV modules) | The CEC list confirms the module was tested to UL 61730 / IEC 61215 by a recognized lab; unlisted modules are excluded |
| Power warranty | Guaranteed output in the final warranty year | Manufacturer limited warranty document | The single number that says how much output the maker stands behind at year 25 or 30 |
| Product warranty | Years of cover against defects | Manufacturer limited warranty document | Separate from the power warranty, and often shorter |
| Warranty terms | Labor and shipping cover, transferability, registration conditions | Manufacturer limited warranty document | A long warranty that excludes labor can leave you paying for every replacement visit |
| Temperature coefficient | Pmax %/°C | Datasheet; cross-checked against the CEC listing | How much output falls on a hot roof; matters most in hot climates |
| Rated efficiency | Module efficiency at STC | Datasheet | Matters only when roof area is the constraint |
| Certified performance | PTC rating relative to STC nameplate | CEC Solar Equipment List | PTC is the CEC’s field-like rating; a higher PTC/STC ratio means less nameplate inflation |
Weights and the scoring sheet will be published with the first ranking. Price is deliberately not a criterion: module price is a small and variable share of an installed system.
What a datasheet ranking cannot tell you
Manufacturer survival. A 25-year warranty is only as good as the company that issued it. Several module brands sold in the US have exited the market within the life of their warranties. We will show which maker issues each warranty and where it is domiciled, but a datasheet cannot predict solvency.
Installation quality. Roof penetrations, wiring and the inverter choice affect lifetime output and leaks far more than the difference between two listed panels. That is the installer’s workmanship, covered on workmanship vs manufacturer warranty.
Real degradation. A power warranty is a floor, not a forecast. NREL’s review of field data (Jordan and Kurtz) found a median degradation rate of about 0.5% a year across crystalline silicon systems; individual products can be better or worse than their warranty curve.
How to apply the method to your own quotes
- 1Find the exact model number on the proposal
Not just the brand. One brand sells several lines with different warranties.
- 2Look it up on the CEC Solar Equipment List
Confirm it is listed and note its PTC and STC ratings.
- 3Download the warranty document, not the brochure
Read the year-25 (or year-30) output guarantee, the product years, and whether labor is covered.
- 4Compare temperature coefficients if you live somewhere hot
A difference of 0.05 %/°C adds up over thousands of hot hours.
- 5Compare the installed price per watt, not the panel
Use the proposal analyzer to put two quotes on the same basis.
Panel type is mostly settled
Almost every residential module now sold in the US is monocrystalline, and the differences that remain between cell technologies (PERC, TOPCon, heterojunction, back-contact) show up in the datasheet fields above: efficiency, temperature coefficient and the degradation warranty. You do not need to choose a technology separately. See monocrystalline vs polycrystalline for the background.
