The use of **half-cut monocrystalline solar cells** minimizes electrical losses and improves performance under partial shading, which, in practice, reduces the risk of daily production drops. The **multi-busbar technology with rounded strips** is also noteworthy, as it effectively collects current from the cells and is less susceptible to microcracks that can occur during transportation and operation at varying temperatures. The NU-JD series also emphasizes **a design focused on longevity** - solutions that minimize heat buildup and provide resistance to typical environmental factors, which are particularly important when installing on industrial sites. For installers, **simplified wiring and assembly logistics** are also key features, as they reduce the time required for installation and help to lower the overall system cost. This is the choice for investors who want stable production and predictable performance over many years. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 550-600W\*\* median - Power density of 212.9 W/m² matches the \*\*PERC 550-600W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 27.5 kg (3.3 kg below \*\*PERC 550-600W\*\* median of 30.8 kg) allows easier transport and roof mounting - Ranked #8519 out of 14005 panels for efficiency in the database ## Questions ### Is the Sharp NU-JD series still available for purchase? The Sharp NU-JD series has been discontinued and is no longer offered as a new product through authorized distributors. Leftover stock may occasionally appear in the market, but availability is limited and unreliable. If you are planning a new installation, it is advisable to consider Sharp's current lineup or other Tier 1 manufacturers with comparable power output and technology to ensure long-term service and parts availability. ### What warranty does the Sharp NU-JD 550W panel carry? Sharp provides a 15-year product warranty and a 25-year linear power output guarantee for the NU-JD series. At least 98% of nominal power is guaranteed in year one, declining linearly to a minimum of 85.04% of Pnom by year 25. These are strong warranty terms consistent with a Tier 1 Japanese manufacturer and make the series a sound choice for long-term commercial projects. ### What is half-cut PERC technology and why did Sharp use it in the NU-JD series? Half-cut PERC technology splits each PERC cell into two halves, reducing internal resistance and resistive losses. The result is better performance under partial shading conditions — such as chimneys, antennas, or adjacent panel rows — because a shaded half-cell does not disable the entire string. In the NU-JD series, Sharp combines half-cut cells with multi-busbar rounded ribbons, which improves current collection and reduces the risk of microcracks during transport and thermal cycling. ### What snow and wind load ratings do Sharp NU-JD modules have? The Sharp NU-JD 550W module is rated for a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa. This makes it suitable for commercial rooftops in heavy-snow regions and open-field PV farms exposed to strong winds. Always verify local structural requirements with a licensed engineer when designing the mounting system. ### How heavy is the Sharp NU-JD 550W panel and is it easy to install? The Sharp NU-JD 550W module weighs 27.5 kg and measures 2,278 × 1,134 × 35 mm. These are standard dimensions for a 550 W commercial-grade module designed for rooftop or ground-mounted utility and C&I projects rather than residential rooftops. Sharp incorporated wiring and logistics features intended to shorten installation time, which translates to meaningful BoS cost savings on large-scale deployments with hundreds of panels. ### Are Sharp NU-JD 550W panels compatible with 1,500 V system voltage inverters? Yes, the NU-JD series is certified for 1,500 V DC system voltage, which is the industry standard for large commercial and utility-scale PV installations. Higher system voltage allows more modules per string, reducing cabling runs and transmission losses. When sizing an inverter, verify that the MPPT input voltage range matches the expected string voltage across the full operating temperature range of the NU-JD module. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2305_NUJD_545_550_HC-Mono_Datasheet_12Y_EN-02082bc580b8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [Sharp NU-JD540](https://comparepv.com/panel/sharp-nu-jd540) | 540 W | -10 W, -0.4 pp | | [Sharp NU-JD545](https://comparepv.com/panel/sharp-nu-jd545) | 545 W | Very close match | | [Sharp NB-JD570](https://comparepv.com/panel/sharp-nb-jd570) | 570 W | Cooler, heavier, +5 yr warranty | | [Sharp NB-JD575](https://comparepv.com/panel/sharp-nb-jd575) | 575 W | Heavier, +1.0 pp, +5 yr warranty | | [Sharp NB-JD580](https://comparepv.com/panel/sharp-nb-jd580) | 580 W | Heavier, +1.1 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/sharp-nu-jd550 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
