Company Background
Leapton Solar is a manufacturer of solar panels and mounting systems, originally founded in Kobe, Japan in 2012. Despite being a newer entrant compared to brands that launched in the early 2000s, Leapton has built a solid reputation as a Tier 1 manufacturer with a growing global footprint.
Leapton achieved a Tier 1 bankability rating from BloombergNEF, which reflects the company’s financial stability and ability to honor long-term warranties — not necessarily a measure of panel quality, but an important signal that Leapton is a legitimate, established player. Panels are manufactured in Changshu, China and distributed worldwide.
Current annual production capacity sits at 660MW, with a new 2GW facility in development — a significant expansion that signals long-term commitment to the market. For NC homeowners, that kind of stability matters when you’re counting on a 25-year warranty.
PV Evolution Labs Top Performer
PV Evolution Labs, supported by DNV GL, conducts independent assessments of solar panel reliability under real-world conditions. Participation is voluntary — manufacturers pay to have their panels tested — and the resulting Top Performers List is recognized globally as a credible benchmark.
Leapton panels have not yet appeared on the PV Top Performers List. Given that Leapton is still a relatively newer manufacturer, this isn’t necessarily a red flag — many solid brands haven’t participated. As Leapton grows and undergoes more independent testing, this may change. It’s worth keeping in mind when comparing them to brands with longer testing track records.
Unique Features of Leapton Solar Panels
Leapton has secured certifications from TUV, PID, Chemitox, SGS, CQC, and GAMCORP — a strong set of internationally recognized credentials that confirm their panels meet the quality and safety standards required for sale in major global markets.
Key differentiating features across their lineup include half-cut monocrystalline cell technology, 9-busbar designs on select models, low temperature coefficients suited for hot climates, and bifacial options for commercial applications. Their LP166 series models also offer black frame and all-black cell options — increasingly popular for residential installs where aesthetics matter.
Leapton’s Warranty Coverage
Leapton’s warranty structure varies by model, so it’s important to confirm coverage specifics with your installer before purchase.
Product warranty: 15 years on current models, covering manufacturing defects and panel failure. This is above the 10-year industry standard but below the 25-year coverage offered by top-tier brands. Confirm the specific warranty term for the model you’re being quoted.
Performance warranty: 25 years, guaranteeing 80.68% output for monocrystalline modules and 80.7% for polycrystalline modules. Annual degradation is rated at 0.70% — slightly above the best-in-class 0.50% but within the acceptable industry range. This means your panels will still produce meaningful power well into their third decade.
One important note: warranty value is only as good as the company standing behind it. Leapton’s Tier 1 status and expanding manufacturing capacity are positive indicators of long-term stability — but as with any newer brand, it’s worth discussing with your installer how warranty claims are handled in practice.
Leapton Solar Panel Models
LP158*158-M-60-MH
Leapton’s entry-level residential model. Power output ranges from 325W to 340W with efficiency up to 20.1%. It uses 158mm x 158mm half-cut monocrystalline cells and is available in silver or black aluminum frames. Solid specs for the price, though it’s the least capable panel in Leapton’s current residential lineup.
LP166*166-M-66-MH
Leapton’s strongest residential option. The larger 166mm cell format and 66-cell configuration push power output to 385W–415W, with efficiency up to 20.5%. The 9-busbar design reduces resistive losses and improves shade tolerance. A low temperature coefficient of -0.28%/°C makes this panel particularly well suited to hot climates — including North Carolina summers. Available in silver or black frames.
LP166*166-M-60-MH
A compact version of the LP166 series with 6 fewer cells, resulting in a panel that’s approximately 9% smaller — better suited for tighter or irregularly shaped roofs. Power output is 360W–380W. Available with black framing and all-black cells, making it one of the more visually appealing options for residential installs where aesthetics are a priority.

Advantages and Disadvantages
Advantages
- Tier 1 manufacturer: BloombergNEF bankability rating confirms financial stability and long-term reliability.
- 15-year product warranty: Above the 10-year industry standard — solid coverage for a mid-tier brand.
- Strong efficiency: Up to 20.5% efficiency on the LP166 series is competitive with better-known brands.
- Low temperature coefficient: The LP166*166-M-66-MH’s -0.28%/°C rating holds up well in NC’s hot summers.
- Aesthetic options: All-black configurations available for homeowners who care about curb appeal.
- Multiple international certifications: TUV, PID, SGS, and others confirm build quality meets global standards.
Disadvantages
- Less established track record: Founded in 2012, Leapton has less history than brands with 20+ years of field data.
- Not on PV Top Performers List: No independent PVEL validation yet — harder to benchmark against tested competitors.
- 0.70% annual degradation: Slightly above best-in-class — not a dealbreaker, but worth factoring into long-term output projections.
- Limited US installer familiarity: Fewer installers have hands-on experience with Leapton compared to more widely distributed brands.
Pricing in North Carolina
A typical residential solar system using Leapton panels in North Carolina runs between $25,000 and $35,000 gross before incentives, depending on system size, roof complexity, and installer. After applying the 30% federal Investment Tax Credit (ITC), the effective cost drops to approximately $17,500–$24,500.
NC homeowners who qualify for Duke Energy’s PowerPair rebate — up to $5,400 for eligible solar and battery installs — can reduce their out-of-pocket cost further. The 30% ITC is locked in through 2032, so there’s no urgency to rush, but there’s also no reason to wait.
