The 0.05-0.07 pp lead means a marginally smaller mounting footprint for the same array power. - **Half-cut cells reduce shading losses** - 144 Mono PERC half-cut cells split each standard cell in two, cutting power losses from partial shading by up to half compared to full-cell modules and lowering hot-spot risk due to reduced current per cell path. - **25-year linear power warranty** - The Shark series carries a 25-year performance warranty (90% power output at year 10, 80% at year 25), matching the industry-standard terms for the 550 Wp Mono PERC segment and comparable to what IBC Solar and Goldi Solar offer. - **Fast-growing manufacturer with expanding capacity** - Loom Solar (India, founded 2018) surpassed INR 1,000 crore turnover in 2026 and is scaling integrated PV module manufacturing toward 1.2 GW capacity, improving supply chain stability and warranty support in its home market. ## Cons - **PERC technology is being superseded by N-Type TOPCon** - This series uses P-type Mono PERC cells, while the >550 Wp segment is clearly shifting toward N-type TOPCon in 2025-2026 (including newer models from the same manufacturer), which offers lower LID degradation and better high-temperature performance. This specific variant does not use the newer technology. - **Manufacturer not on the BNEF Tier 1 list** - Loom Solar does not appear on the BloombergNEF Tier 1 list for Q2 2026, unlike many established players in the 550 Wp segment (e.g., Jinko, LONGi, Trina, JA Solar) — a relevant factor for project bankability and long-term warranty backing over the 25-year term. - **No bifacial capability in this variant** - This specific 550 Wp Shark variant is monofacial (is\_bifacial: false), even though the manufacturer offers bifacial versions of the same series capable of additional rear-side energy yield — buyers of this SKU forgo that option. ## About this series The Loom Solar Shark series is a solution for demanding installations, where maximum performance on limited roof space matters most. These panels utilize **Mono PERC technology with half-cut cells (144 cells)**, which directly translates into better behavior under partial shading conditions - cells cut in half reduce energy losses due to shading by up to half compared to classic modules. Available **bifacial** versions allow for the absorption of solar radiation from both sides of the panel, which under appropriate mounting conditions can increase energy yield by several dozen percent. The Shark series also stands out for its **excellent performance in diffused light** - the panels maintain high efficiency even on cloudy days and in fog, which is particularly important in the Polish climate. Newer models in the series use **N-Type TOPCon technology with 16 busbars**, ensuring even higher energy conversion quality and longer cell lifespan. The Shark series is an ideal choice for both residential and commercial installations, where the priority is **high productivity per square meter** and reliability over years of operation. ## Notable figures - Efficiency of 21.4% matches the \*\*PERC 550-600W\*\* median - At 213.1 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - At 29.0 kg, this panel is 1.8 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg) - easier handling during installation - #8462 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Loom Solar Shark panel and what makes it stand out technically? The Loom Solar Shark delivers a maximum power of 550 Wp with a module efficiency of approximately 21.3%. The core technology is Mono PERC half-cut cells — 144 cells per module — which reduce internal resistance and shading-related energy losses. The module measures 2278 × 1134 × 35 mm and weighs approximately 29 kg, making it suitable for both sloped and flat roof installations. ### How does the Loom Solar Shark 550W perform in overcast or foggy conditions typical of Northern/Central European climates? The Shark series is engineered for strong low-light performance. Mono PERC cells maintain high efficiency on cloudy days and in fog, which is a key advantage in climates with frequent overcast skies. The manufacturer highlights superior output under diffuse irradiance, resulting in a higher annual energy yield compared to standard polycrystalline modules in the same conditions. ### What warranty does the Loom Solar Shark come with and what does it cover? Loom Solar provides a 25-year power performance warranty for the Shark series. The terms guarantee at least 90% of nominal power output during the first 10 years and a minimum of 80% after 25 years. Since Loom Solar is headquartered in India, buyers should confirm that their local distributor offers full in-country warranty support, including module replacement if needed. ### How do the half-cut cells in the Loom Solar Shark reduce energy losses from partial shading? Half-cut technology splits each standard cell into two halves, lowering internal resistance and cutting shading-related losses by up to approximately 50% compared to conventional full-cell modules. With 144 half-cut cells per module, partial shading from chimneys, dormers, or antennas has a significantly smaller impact on total system output than with traditional 60- or 72-cell full-cell designs. ### What mechanical loads can the Loom Solar Shark withstand — is it suitable for areas with heavy snowfall? The Loom Solar Shark is certified for snow loads up to 5400 Pa (approximately 550 kg/m²) and wind loads up to 2400 Pa. These are strong mechanical ratings, well-suited for Central European winter conditions with heavy snowfall. The module features a reinforced aluminum frame, tempered glass, and an IP68-rated junction box, ensuring long-term durability and weatherproofing. ### Is the Loom Solar Shark available in a bifacial version and how does it differ from the standard model? Loom Solar does offer a bifacial variant of the Shark series, which captures sunlight from both the front and rear of the module, generating 30–50% more energy when installed above reflective surfaces such as gravel or a white roofing membrane. The standard monofacial Shark model is better suited and more cost-effective for conventional rooftop installations where reflected rear irradiance cannot be captured. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/550_Wp_Mono_Facial_DataSheet-eb1b2f82fcba.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.2 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.1 pp | | [Loom Solar HD144N-550](https://comparepv.com/panel/loom-solar-hd144n-550) | 550 W | Cooler, heavier, +5 yr warranty | | [Loom Solar HD144N-560](https://comparepv.com/panel/loom-solar-hd144n-560) | 560 W | Cooler, heavier, +5 yr warranty | | [Loom Solar HD144N-570](https://comparepv.com/panel/loom-solar-hd144n-570) | 570 W | Cooler, +0.7 pp, +5 yr warranty | | [Loom Solar SHARK-590](https://comparepv.com/panel/loom-solar-shark-590) | 590 W | Cooler, +1.4 pp, +5 yr warranty | | [Loom Solar SHARK 600](https://comparepv.com/panel/loom-solar-shark-600) | 600 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/loom-solar-shark-550 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
