Hyundai 440W Bifacial Full-Black Solar Panel, Pallet of 36 – HiN-T440NF(BK)

Product Overview This listing is one pallet of 36 HD Hyundai HiN-T440NF(BK) solar panels. Each panel is a 440-watt module with an all-black look, so the pallet adds up to 15,840 W of rated power (36 × 440 W, measured at STC). The panels turn sunlight into DC electricity, which an inverter then converts into AC power for a home or building. HD Hyundai's datasheet lists 36 modules per pallet and a packing pallet weight of 912 kg (about 2,010 lb). Each panel uses N-type TOPCon cells, a newer type of monocrystalline silicon cell, and it is bifacial. Bifacial means the back of the panel can also collect light, such as sunlight reflected off the ground or a light-colored surface under the array. Both the front and back are 2.0 mm glass. At 22.53% efficiency, more of the sunlight that hits the panel becomes electricity, so you get more watts from the same roof space. Each panel has 108 half-cut cells, measures about 67.8 × 44.6 inches, and weighs about 54 lb. HD Hyundai backs the panels with a 25-year product warranty and a 30-year performance warranty. Best For Homes where appearance matters: HD Hyundai describes the NF(BK) series as a full-black design for residential use, for homeowners who want an all-black array. Carports and raised structures: HD Hyundai lists the NF(BK) series as suited to carport applications. On raised structures, light can reach the back of the panel, where the bifacial design can add some extra output. Projects with limited space: At 440 W and 22.53% efficiency, fewer panels may be needed to reach a target system size than with lower-wattage panels. Larger arrays: A pallet gives you 36 modules of the same model and ratings, which keeps string design simpler than mixing leftover panels. Choose the single-panel listing instead for a small array or a replacement. Key Features & Specifications Specification Details Sold as One pallet of 36 modules Product type Bifacial N-type TOPCon monocrystalline solar panel, full black Model / manufacturer part number HiN-T440NF(BK) Rated power (STC), per panel 440 W. STC (Standard Test Conditions) is the lab test used to rate every panel the same way. Total rated power, full pallet 15,840 W (36 × 440 W) Power class sorting Positive power sorting: 0 to +5 W above the 440 W rating (test uncertainty ±3%) Module efficiency 22.53% Open-circuit voltage (Voc) 38.8 V at STC. This is the panel's voltage with nothing connected, measured at 25°C (77°F) cell temperature. It goes up in cold weather, so use the cold-temperature value when checking inverter voltage limits. Short-circuit current (Isc) 14.39 A at STC; 15.94 A at the BNPI rating; up to 17.99 A at 25% rear-side gain (HD Hyundai's rear-gain table). Use these to check inverter and microinverter current limits. Voltage / current at max power (Vmpp / Impp) 32.3 V / 13.63 A Bifacial rating (BNPI) 488 W (Isc 15.94 A), measured with extra light on the back of the panel (135 W/m² rear, 1,000 W/m² front). Real rear-side gain depends on the site. Bifaciality 80% ±10% (how well the back side converts light compared with the front) Temperature coefficients Pmax −0.30%/°C; Voc −0.25%/°C; Isc +0.046%/°C. Power drops a little as the panel heats up, and voltage rises in the cold. Solar cells 108 (6 × 18) N-type TOPCon monocrystalline, 16-busbar half-cut bifacial cells Maximum system voltage 1,500 VDC Maximum reverse current 30 A Nominal module operating temperature 44°C ±2°C Operating temperature −40°C to +85°C Maximum test load 5,400 Pa front / 5,400 Pa rear (see the installation manual for mounting conditions) Fire performance Type 29 Construction Front: 2.0 mm semi-tempered glass with anti-reflective coating.

Pallet configuration 36 modules per pallet; packed vertically (HD Hyundai datasheet, Shipping Configurations) Packing pallet weight 912 kg (about 2,010 lb) per HD Hyundai's datasheet. This is the whole packed pallet, not one panel. What You May Also Need Usually required Inverter or microinverters: Converts the panel's DC power to AC. Choose equipment whose input voltage and current limits fit this panel's Voc (38.8 V at STC, higher in cold weather) and Isc (14.39 A at STC, up to 17.99 A with rear-side gain). Roof mounts or ground mounts: Rails, attachments and module clamps to hold the panel. Choose clamps whose listed frame-height range includes this panel's 30 mm frame, and follow HD Hyundai's installation manual for clamping zones. PV cables: Extension cables carry power from the array to the inverter or combiner. This panel uses Stäubli MC4 connectors, so check the connector type on any cable you add. May be required Rapid shutdown devices: Systems on buildings generally must meet NEC rapid shutdown rules (section 690.12), depending on the code edition your area uses. Some inverter systems include this, and others need separate devices. Disconnects and breakers: Required by code in many systems to safely isolate the array and inverter. Grounding hardware: The frame has grounding holes. Use the grounding method listed for your racking system, such as bonded clamps or a grounding lug. (For example, the IronRidge XR-LUG-04-A1 grounding lug works only with IronRidge XR Rails.) Optional upgrades PV cable clips: Hold the panel's leads neatly along the frame and keep them off the roof surface. Check that the clip's frame-thickness range fits this panel. Junction boxes and conduit mounts: Help move wiring from the array into conduit cleanly on a roof. Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware. Important Considerations High current. Isc is 14.39 A at STC and 15.94 A at the BNPI rating. HD Hyundai's rear-gain table lists Isc up to 17.99 A at 25% rear-side gain. Make sure the inverter, microinverter or optimizer input current rating and any fuses account for this. Cold-weather voltage. Voc rises as temperature drops (−0.25%/°C). When wiring panels in series, calculate string voltage at your site's coldest temperature so it stays under the inverter's limit and the 1,500 V module limit. Bifacial rating vs. STC rating. The 488 W BNPI figure assumes light on the back of the panel. Size your system and production estimates from the 440 W STC rating unless you have a site-specific estimate of rear-side gain. Handling. HD Hyundai's datasheet says only qualified personnel should install the panel, to be aware of dangerous high DC voltage, and not to handle or install modules when they are wet. Each panel is glass on both sides and weighs about 54 lb. Pallet weight. A full pallet is about 2,010 lb (912 kg) as packed, according to HD Hyundai's datasheet. Confirm that your delivery location and unloading equipment can handle a load this heavy before you order. Mounting loads. The 5,400 Pa test loads apply to the mounting methods in HD Hyundai's installation and operation manual. Follow it for clamp positions and mounting.
