**N-Type TOPCon cells with 16 busbars** - The use of N-type TOPCon half-cut cells with 16 busbars delivers lower LID/LeTID degradation and reduced resistive losses compared to older PERC panels, translating into higher and more stable energy yield over the module's lifetime. - **Bifacial design with dual glass and IP68 rating** - Two-sided power generation can add up to roughly 10-25% extra output on highly reflective surfaces (grass, light-colored concrete), while the IP68-rated dual-glass enclosure improves resistance to moisture and microcracks. - **30-year linear power warranty** - The manufacturer offers a 30-year linear power output warranty, matching the longest terms offered by leading players in the segment such as Trina Solar and JinkoSolar in their flagship TOPCon lines. - **Proven series on the market since 2021** - Shark Bifacial has been in continuous production since 2021 (series\_info.discontinued = false), meaning parts availability, service support, and a field-track record confirming the technology's stability under real-world conditions. - **Rapidly scaling manufacturing base in India** - Loom Solar (founded 2018) crossed INR 1,000 crore in turnover in 2026 and is expanding module manufacturing capacity to 1.2 GW, improving supply chain availability and price competitiveness in the Indian and export markets. ## Cons - **Efficiency below comparable TOPCon models** - Efficiency of 21.29-22.07% is lower than direct peer comparables in this power class (up to 570 Wp) - Horay Solar HS 191R-132 TC Basin reaches 23% and Silfab Commercial NTC 22.3% - meaning a larger installed area is needed for the same installed power. - **12-year product warranty shorter than category leaders** - The manufacturing defect warranty is 12 years, while leading TOPCon manufacturers (Trina Solar's TrinaProtect program, JinkoSolar) now standardly offer a 25-year product warranty in 2026, making this line less competitive on this parameter despite the matching 30-year power warranty. - **No BNEF Tier 1 status** - Loom Solar does not appear on BloombergNEF's Tier 1 manufacturer list (Q2 2026), unlike more established brands in the comparable segment such as Silfab, which can matter for bank financing of larger commercial and ground-mount projects. ## About this series The SHARK Bifacial series is Loom Solar's answer to rising expectations for photovoltaic panels installed on roofs and ground surfaces with high light reflectivity. The panels use **N-Type TOPCon cells** in a half-cut configuration together with **16 busbars**, resulting in more even current distribution, lower resistive losses, and greater cell durability compared to conventional PERC technology. The series' biggest advantage, however, is its **bifacial dual-sided design** - the module generates energy from both the front and rear side, so on reflective surfaces (grass, white roofing, light-colored concrete) an installation can produce anywhere from a few percent up to over twenty percent more energy than a standard monofacial panel. The **dual-glass construction** along with an **IP68-rated** housing provides added protection against moisture, microcracking, and light-induced degradation, directly translating into a lower LCOE over the system's lifetime. The SHARK Bifacial series is especially appealing for ground-mounted installations, solar farms, and industrial sites, where maximizing energy yield from limited mounting area matters, while also demanding strong resilience to harsh operating conditions and long-term performance guarantees. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 220.7 W/m² is 3.8 W/m² below \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - needs more roof space - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - At 32.5 kg, this panel is 1.3 kg heavier than the \*\*TOPCon 550-600W\*\* median (31.2 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How much extra energy does the Loom Solar Shark Bifacial panel produce thanks to its double-sided design? Thanks to its bifacial construction, the Shark Bifacial panel generates power from both the front and rear sides. On highly reflective surfaces such as a white roof, light-colored concrete, or grass, the installation can achieve roughly ten to twenty-plus percent more energy than a standard monofacial panel of the same 570 Wp power rating. The actual gain depends on ground albedo, tilt angle, and mounting height. ### How does N-Type TOPCon technology in the Shark Bifacial panels differ from conventional PERC cells? The N-Type TOPCon cells used in the Shark Bifacial series have lower resistive losses and degrade more slowly than conventional PERC cells. Combined with the half-cut layout and 16 busbars, current is distributed more evenly across the cell surface, resulting in higher initial efficiency and a smaller power drop over time, especially at high operating temperatures. ### What warranty comes with the Loom Solar Shark Bifacial panels? Shark Bifacial panels come with a 12-year product warranty covering material and manufacturing defects, plus a 30-year power output warranty guaranteeing the declared cell performance. This is a long coverage period for the Indian market and places the series among premium models, which matters when estimating LCOE for ground-mount and industrial installations. ### Are Shark Bifacial panels suitable for ground-mount installations and solar farms? Yes, the series was designed specifically for such applications. Dual-side power generation from the front and rear maximizes energy yield from limited land area, which is key for large PV farms. The IP68-rated enclosure and dual-glass construction provide added resistance to moisture and harsh weather conditions typical of ground-mount installations. ### Does the dual-glass, IP68-rated design protect the Shark Bifacial panel from microcracks and moisture? Yes, the dual-glass construction, used instead of a rear backsheet, significantly increases the module's mechanical stiffness and reduces the risk of cell microcracks during transport and installation. The IP68 rating protects the junction box and module interior from moisture ingress, which limits light-induced degradation and extends the panel's real-world trouble-free service life. ### Who manufactures the Shark Bifacial panels, and does that affect service availability in Europe? The Shark Bifacial panels are made by Loom Solar, an Indian manufacturer. The company primarily serves the Indian and export markets, so before buying in Europe it's worth checking with a local distributor how warranty claims are handled, spare-part lead times, and whether EU-required certifications are in place, since after-sales support may work differently than with European manufacturers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Shark-550-datasheet-TOPCon-25883312f14f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [Loom Solar SHARK 550](https://comparepv.com/panel/loom-solar-shark-550) | 550 W | Hotter, -0.7 pp, -5 yr warranty | | [Loom Solar HD144N-550](https://comparepv.com/panel/loom-solar-hd144n-550) | 550 W | -20 W, -0.8 pp | | [Loom Solar HD144N-560](https://comparepv.com/panel/loom-solar-hd144n-560) | 560 W | -10 W, -0.4 pp | | [Loom Solar SHARK-590](https://comparepv.com/panel/loom-solar-shark-590) | 590 W | +20 W, +0.7 pp | | [Loom Solar SHARK 600](https://comparepv.com/panel/loom-solar-shark-600) | 600 W | +30 W, lighter, +1.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, lighter, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, lighter, +2.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +70 W, lighter, +2.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +65 W, lighter, +2.5 pp | --- Source: https://comparepv.com/panel/loom-solar-hd144n-570 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.
