Light for its output, no clear weak spot
The SHARK series in the TOPCon N-Type Bifacial version is Loom Solar's response to the growing demands of modern photovoltaic installations - both residential/prosumer and commercial. Unlike popular P-type PERC panels, N-type technology delivers lower annual degradation and higher resistance to the LID (Light Induced Degradation) effect, which directly translates into a longer module lifespan and higher energy yield throughout the entire service life. The Half-Cut design with 16 busbars (16BB) effectively limits losses under partial shading and minimizes the risk of cell microcracks - a problem that shortens the lifespan of many standard modules. Double-sided radiation absorption (bifaciality) allows additional energy to be captured from light reflected off the ground, which is particularly cost-effective for ground-mounted installations and light-colored roofs. The low temperature coefficient means the panel maintains high efficiency even on hot days, while the anti-reflective coating (ARC) glass improves yield under diffuse light and cloudy conditions. The manufacturer guarantees a 30-year linear power warranty with annual degradation below 0.3% - making this series exceptionally attractive to investors seeking a reliable, long-term return on investment.
Ranking
Signals from the data
Residential, commercial, shaded-installations and hot-climate.
Top 10% of the TOPCon 600-650 W segment, against a median of 53.1.
Top 20% of the TOPCon 600-650 W segment, against a median of 22.80%.
Top 21% of the TOPCon 600-650 W segment, against a median of 227.7.
The 625 Wp variant reaches up to 23.23% efficiency, outperforming the comparable Longi Hi-MO 7 (23.1%), matching Techwise Sun-Pursuit Plus (23.14%), and clearly beating Leapton LP182 (22.36%). This translates into a real energy yield advantage per square meter of roof area.
The higher-power SKUs in the series (from roughly 575 Wp) use N-type TOPCon cells with Anti-LID/Anti-PID technology, with first-year degradation around 1% and annual degradation below 0.3% thereafter - an improvement over typical P-type PERC modules.
The manufacturer guarantees a 30-year linear power warranty alongside a 15-year product warranty, matching the standard set by segment leaders such as Longi Hi-MO 7 and giving investors predictable, long-term returns.
Half-cut cells with 16 busbars (16BB) reduce partial-shading losses and lower microcrack risk, which matters during transport and installation on large roof arrays.
The series spans 5 variants from 275 Wp to 625 Wp, covering both small residential installations and commercial/utility-scale projects under a single manufacturer portfolio.
The SHARK name covers both older P-type Mono PERC variants (lower power range, roughly 275-550 Wp) and newer N-type TOPCon bifacial modules (575-625 Wp). Benefits described for the flagship SKU (bifaciality, low LID degradation) do not apply to the entire lineup - buyers must check the specific variant code against the datasheet.
Unlike peer comparable Longi Solar (a global Tier-1 leader), Loom Solar - operating since 2018 - does not appear on the 2026 BloombergNEF Tier-1 lists. This can matter for bank financing of larger commercial projects that require Tier-1 sourced modules.
Certifications (ALMM, BIS) and the support model (3-7 day complaint resolution, video-call service) are built around the Indian market and the PM Surya Ghar scheme. For European installers, this creates uncertainty about the local service network backing the 30-year warranty.
- Efficiency of 23.2% matches the TOPCon 600-650W median
- Power density of 232.3 W/m² packs 4.6 W/m² more into the same footprint vs TOPCon 600-650W median (227.7 W/m²)
- At -0.29%/°C, hot weather performance is typical for TOPCon 600-650W panels
- Weight of 28.0 kg (4.7 kg below TOPCon 600-650W median of 32.7 kg) allows easier transport and roof mounting
- In the top 9% for efficiency among all TOPCon panels
