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.

What owners get
Top-tier efficiency in its class

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.

N-type TOPCon with low degradation

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.

30-year linear power warranty

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 16BB cell design

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.

One platform spanning the full power range

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.

Trade-offs
Inconsistent cell technology across the series

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.

No confirmed BNEF Tier-1 status

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.

Service ecosystem centered on India

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.

Common questions

6 answered
How does the TOPCon N-type technology in the Loom Solar SHARK series differ from PERC panels?
TOPCon N-type technology delivers lower annual power degradation (below 0.3%) and higher resistance to LID (Light Induced Degradation) compared to standard P-type PERC modules. This translates into higher cumulative energy yield over the full 30-year operating period. For the system owner, it means more kilowatt-hours from the same roof area compared to lower-cost PERC alternatives.
What does Half-Cut 16BB mean in the SHARK panels, and why does it matter?
Half-cut cells are split in half, reducing internal resistance and heat losses within the module. 16BB (16 busbars) increases the current-collection area per cell and minimizes the risk of microcracks during shipping and operation. In practice, SHARK panels perform better under partial shading — for example from a chimney or dormer — than conventional full-cell modules.
What warranties are included with the Loom Solar SHARK 600 Wp series?
Loom Solar provides a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty with annual degradation guaranteed below 0.3%. This means the module retains the vast majority of its rated 600 Wp output after three decades of operation — one of the longest power warranties available in this power class on the market.
Are Loom Solar SHARK 600W panels suitable for sloped roofs, or only for ground-mounted systems?
The SHARK 600W series is compatible with standard racking systems for both sloped roofs and ground-mounted installations. The module measures 2278 x 1134 mm and weighs 30 kg, so confirm roof load capacity and available surface area with your installer before purchasing. The Half-Cut 16BB design improves performance under partial shading, which is common on roofs with chimneys or dormers.
How does the bifacial design work in SHARK panels, and how much extra energy can I realistically expect?
Bifacial SHARK panels capture irradiance from both the front and rear side of the module — the rear absorbs light reflected off the ground or rooftop surface. Actual power gain depends on substrate albedo and mounting tilt, typically ranging from a few percent to over ten percent in additional annual energy yield. The effect is greatest in ground-mounted systems with bright gravel or soil, and on white or light-gray roofing.
Do Loom Solar SHARK 600W panels lose significant output on hot summer days?
The SHARK series features the low temperature coefficient typical of N-type TOPCon cells, meaning power losses at elevated temperatures are smaller than in older PERC technology. The anti-reflective coating (ARC) on the front glass further improves yield under diffuse light and partial cloud cover. Under typical Central European climate conditions, the module maintains high efficiency throughout the entire summer season.
