The use of **dual glass construction** (glass-to-glass) enhances resistance to stress and material aging, resulting in greater predictability of performance over the long term. This solution is particularly appealing to investors who want to minimize the risk of performance degradation and prioritize durability over compromises. A key feature of the series is **bidirectional energy harvesting**, which allows for better utilization of reflected light - important on bright roofs, when mounted on the ground, and in installations with elevated structures. The modules are attractive for residential and commercial installations, where power density per unit area and aesthetics are important - the **full black finish** variants are particularly well-suited for modern architecture. An additional advantage is **extended product and linear warranty**, which supports the overall profitability of the investment. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - At 225.2 W/m² power density, roof space requirements are typical for \*\*TOPCon 450-500W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 25.0 kg, weight matches the \*\*TOPCon 450-500W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty comes with the Leapton LP182\*210-M-48-NB panels? The LP182\*210-M-48-NB series includes a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The N-type TOPCon technology keeps annual degradation at or below 0.4%, meaning the module retains most of its rated power after three decades. This is one of the longest combined warranties currently available on the residential and commercial PV market. ### How does TOPCon compare to PERC cells and is the difference noticeable in real-world output? N-type TOPCon cells deliver higher baseline efficiency (up to roughly 22.5% for this series) and lower long-term degradation than P-type PERC. The practical advantage is better performance at elevated cell temperatures and under diffuse irradiance — both common conditions in Central European climates. This translates into higher annual energy yield per square meter compared to previous-generation PERC modules of equal wattage. ### Does the bifacial design of the LP182\*210-M-48-NB make a real difference on a typical pitched roof? The rear-side gain from bifacial modules depends heavily on surface albedo and mounting clearance. On a dark tile roof the effect is minimal, but on light-colored metal roofing, white gravel, or ground-mount racking with adequate clearance, Leapton specifies a 5–25% additional output from the rear side. For a standard pitched roof a realistic bonus is 5–10%, which meaningfully improves the installation's LCOE over its lifetime. ### Can these panels handle heavy snow loads and high wind pressure? Yes. The dual glass construction of this series is TÜV Nord-certified for snow loads up to 5400 Pa and wind loads up to 2400 Pa. The 5400 Pa snow rating exceeds the structural requirements of most Central European climate zones. The glass-glass design also eliminates the rear backsheet, which over time is more susceptible to moisture ingress and delamination than tempered glass. ### What is the peak power of the Leapton LP182\*210-M-48-NB and how many panels are needed for a 10 kW system? The highest-power variant in this series is rated at 455 Wp under STC. A 10 kW peak system requires approximately 22 modules (22 × 455 W = 10,010 W). The 210R cell format and compact footprint (1762 × 1134 mm) mean that a 22-panel array occupies less roof area than equivalent systems built with lower-wattage legacy modules, which matters when usable roof space is limited. ### Is Leapton a bankable manufacturer and can these modules be used in financed commercial projects? Leapton Energy was founded in 2012 in Kobe, Japan and operates manufacturing facilities in China. The company holds Tier 1 status from independent financial research institutions, meaning its modules are accepted as collateral by banks and leasing funds for commercial and utility-scale PV project financing. This bankability is a key requirement for EPC contractors and investors seeking external financing for larger installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/17e23a95dadb37a2bb41ccd89704af87-a51888afed93.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +2.0 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +2.0 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +2.0 pp | | [Leapton LP182\*182-M-54-NH-430W](https://comparepv.com/panel/leapton-lp182-182-m-54-nh-430w) | 430 W | -20 W, lighter, -1.0 pp | | [Leapton LP182\*182-M-54-NB-435W](https://comparepv.com/panel/leapton-lp182-182-m-54-nb-435w) | 435 W | -15 W, -0.8 pp | | [Leapton LP182\*210-M-48-NB-440W](https://comparepv.com/panel/leapton-lp182-210-m-48-nb-440w) | 440 W | -10 W, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/leapton-lp182-210-m-48-nb-450w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
