Middle of its segment, weak in heat
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.
Ranking
Signals from the data
Commercial and utility-scale.
Hot climates, tight roof space and roofs where every square metre has to count.
Bottom 1% of the N-type 650-700 W segment, against a median of -0.290. Ranked 12,345th in the whole database.
Bottom 17% of the N-type 650-700 W segment, against a median of 23.30%.
Bottom 19% of the N-type 650-700 W segment, against a median of 233.2.
The module matches the power output of leading peer comparables (EGing PV AURORA Pro, Luxen N6 - also 685 Wp), allowing fewer panels per installation and reducing BoS costs (cabling, mounting structure, installation labor).
N-type technology with half-cut, multi-busbar layout (12BB/16BB per manufacturer specs) reduces resistive losses and microcracking, while lower LID degradation than older P-type PERC cells supports more stable long-term yield.
The bifacial glass-glass design captures additional energy from albedo reflected off the ground - the manufacturer claims a 7-20% power boost when mounted at ~1.5 m above a reflective surface, distinguishing it from conventional monofacial panels.
A linear power degradation warranty extended to 30 years gives commercial and industrial investors greater confidence in projected LCOE compared to models offering the standard 25-year power warranty.
IP68 sealing (the highest commonly used standard for PV) protects electrical connections from moisture and dust, which is particularly relevant for ground-mount installations and humid climates.
The materials and workmanship warranty is only 15 years, while many tier-1 N-type TOPCon module manufacturers now offer 20-25 years of product warranty. This can be a significant risk factor when evaluating commercial investments with a 25-30 year time horizon.
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.
- 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
