This can be a significant risk factor when evaluating commercial investments with a 25-30 year time horizon. - **No confirmed BNEF Tier 1 status** - Loom Solar (founded in 2018) does not appear on BloombergNEF's Tier 1 manufacturer list for Q2 2026, unlike many established brands among the peer comparables with longer manufacturing track records. This may affect perceived bankability for institutionally financed projects. ## About this series The SHARK 685 series from Loom Solar is a dual-sided **N-Type TOPCon Bifacial** module engineered for installations where maximizing output per square meter of roof or ground space is the priority. The use of **half-cut** cells arranged in a multi-busbar layout reduces resistive losses and improves the panel's resilience to partial shading, allowing the array to perform more consistently even under challenging light conditions. The **glass-to-glass** bifacial construction captures additional energy from light reflected off the mounting surface, making this model especially attractive for installations over bright, reflective ground cover or elevated racking setups. A sturdy, glass-framed build adds mechanical durability and corrosion resistance, while a sealed **IP68** junction box protects electrical connections from moisture and contaminants throughout the module's service life. This solution is aimed at commercial and industrial investors seeking high power density per installed area and a lower cost per watt compared to conventional monofacial panels. Thanks to its high per-unit wattage, the module reduces the number of panels needed, simplifying system design and lowering balance of system (BoS) costs. ## Notable figures - Efficiency of 22.0% is 1.3pp below the \*\*N-type 650-700W\*\* median (23.3%) - 220.5 W/m² power density is 12.7 W/m² below \*\*N-type 650-700W\*\* median (233.2 W/m²) - requires larger installation area - -0.36%/°C temperature coefficient - 0.07pp worse than \*\*N-type 650-700W\*\* median (-0.29%/°C), expect higher hot weather losses - At 35.0 kg (1.5 kg above \*\*N-type 650-700W\*\* median of 33.5 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### How much extra energy does the bifacial design of the SHARK 685 panel produce? The bifacial glass-glass construction captures light reflected off the ground surface through the rear side of the module. In practice, when mounted over a bright or reflective surface and elevated to around 1.5 meters, the panel can generate anywhere from a few percent up to double digits more energy than its rated power alone would suggest. The actual gain depends on ground albedo, tilt angle, and mounting height. ### How does N-Type TOPCon technology in the SHARK 685 differ from standard Mono PERC panels? N-Type TOPCon cells have a lower degradation rate over time and reduced sensitivity to light-induced degradation (LID) compared to typical P-Type PERC cells, resulting in higher sustained efficiency throughout the panel's lifespan. Combined with the half-cut, multi-busbar cell layout, the panel handles partial shading better and produces less resistive loss, ultimately yielding higher energy output per unit of roof space. ### What is the warranty on the Loom Solar SHARK 685 panel? The manufacturer backs the SHARK 685 with a 15-year product warranty and a 30-year linear power performance warranty. This means that over three decades of operation, the module maintains a guaranteed minimum output level, which is a significant factor when calculating return on investment for commercial and industrial-scale installations. ### Is the SHARK 685 panel suitable for large commercial and industrial installations? Yes, the high unit power of 685 Wp makes this panel especially appealing to commercial and industrial investors seeking high power density on limited roof or ground area. Needing fewer modules to reach a given system size simplifies design, speeds up installation, and lowers balance of system (BoS) costs such as mounting structures, cabling, and optimizers. ### Is the IP68 junction box on the SHARK 685 resistant to moisture and dust? Yes, the junction box carries an IP68 rating, the highest standard for protection against dust ingress and full submersion in water. This safeguards the electrical connections against corrosion and moisture over the panel's entire service life, which is particularly important for installations exposed to rain, ground moisture, or proximity to water bodies, such as floating PV systems. ### Is Loom Solar a reliable manufacturer of photovoltaic panels? Loom Solar is an Indian PV manufacturer and one of the larger suppliers in the Indian solar market, offering models ranging from standard Mono PERC panels to advanced bifacial N-Type TOPCon series like the SHARK 685. The company has been expanding its portfolio of high-wattage modules for both residential and commercial installations, focusing on modern cell technology and strong warranty terms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/datasheet_685_updated_2_0a356899-3c57-4ee4-b192-413f86b24fc0-74c05310b39c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +15 W, cooler, +3.0 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +10 W, cooler, +2.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +120 W, cooler, +3.1 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +115 W, cooler, +2.9 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +110 W, cooler, +2.8 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +105 W, cooler, +2.6 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +75 W, cooler, +2.5 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +100 W, cooler, +2.4 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +95 W, cooler, +2.3 pp | | [AIKO AIKO-A780-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a780-grh78dw) | 780 W | +95 W, cooler, +2.3 pp | | [Jetion JT755SLk(B)](https://comparepv.com/panel/jetion-jt755slk-b) | 755 W | +70 W, cooler, +2.3 pp | --- Source: https://comparepv.com/panel/loom-solar-shark-685 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.
