This places the series among the leaders in the monofacial PERC segment for M6-120 format. - **Half-cut architecture (120 cells)** - Dividing the cells in half reduces resistive losses by approximately 50% compared to full-sized cells and limits the impact of partial shading on the overall module's performance – a practical advantage for roofs with chimneys, dormer windows, or nearby vegetation. - **6 power variants (370–395 Wp)** - The wide range of power outputs, with six different options, allows for precise adaptation of the design to the available roof space and optimization of string configurations without compromising the layout of the modules. - **PERC – Maximizing the Use of Diffuse Light** - Rear passivation of PERC improves the absorption of infrared and diffuse radiation compared to standard mono-BSF cells. This has a measurable impact in the Polish climate, where days with full sunlight represent a small portion of the annual energy balance. - **25-year linear warranty on power** - The manufacturer guarantees a linear performance warranty for 25 years, which is the industry standard and is acceptable to banks and insurers for both prosumer and small commercial installations. ## Cons - **No Tier-1 BNEF status** - AmoSolar does not appear on the list of bankable manufacturers compiled by BloombergNEF (Q1 2026), which could make it difficult for banks to finance projects and may also reduce the perceived credibility of large commercial installations or when selling properties with installed systems. - **Product warranty is only 12 years.** - The 12-year product warranty is weaker than those offered by companies like Meyer Burger (25 years) or the standard 15-year warranties from leading Tier-1 manufacturers (JA Solar, Trina). With a lifespan of 25+ years, the risk of lacking service and support from the manufacturer increases. - **P-type PERC technology, not N-type TOPCon/HJT** - P-type PERC cells exhibit a higher LID (Light-Induced Degradation) rate and a poorer temperature coefficient compared to N-type cells. Over a 25-year lifespan, this could translate to a lower cumulative energy yield compared to newer technologies available in the same price range. - **Lack of bifaciality (single-sided)** - The module does not utilize the albedo effect – typically producing an additional 5–20% of power compared to bifacial modules (e.g., HT-SAAE Double Glass TOPCon with comparable products). This limits the potential for increased energy yield under favorable conditions (reflective surface, gravel, snow). ## About this series The AmoSolar AS370-395M6-120 series consists of monocrystalline **half-cut** modules with a 120-cell architecture, designed to operate reliably even under less-than-ideal rooftop conditions. Dividing the cells in half reduces losses due to conduction and improves performance under partial shading - a practical advantage in installations with chimneys, skylights, or trees nearby. The use of **PERC** technology enhances the utilization of diffuse light, which is important in the Polish climate, where frequent cloud cover and variable sunshine are common. These modules offer a **high efficiency** compared to standard monofacial modules and are easy to integrate into typical rooftop layouts, making it possible to optimize the design without compromising aesthetics. Another advantage is their **resistance to environmental conditions** - the robust construction and sealed junction box ensure reliable operation. This makes them a good choice for single-family homes, small businesses, and hybrid and off-grid installations, where predictable energy production and reliability are key. ## Notable figures - Efficiency of 21.7% is 2.2pp above the \*\*PERC 0-400W\*\* median (19.4%) - Power density of 216.7 W/m² packs 22.3 W/m² more into the same footprint vs \*\*PERC 0-400W\*\* median (194.4 W/m²) - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - Ranked #7588 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the AmoSolar AS370-395M6-120 series carry? The AmoSolar AS370-395M6-120 series comes with a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. This means the manufacturer guarantees a specified minimum energy production level for a full quarter century. It is worth noting, however, that AmoSolar is not classified as a Tier 1 manufacturer — a factor that should be weighed when assessing long-term risk. ### Do the AmoSolar AS370-395M6-120 panels perform well under partial roof shading? Yes. The half-cut cell technology used in this series splits each cell into two halves, significantly reducing losses under partial shading caused by chimneys, dormers, or trees. The module operates as two independent half-strings, so shading one section does not cripple the entire panel. This is a practical advantage in residential installations in Poland, where a perfectly unobstructed roof orientation is rarely achievable. ### What are the dimensions and weight of the AmoSolar AS395M6-120 panel, and is it straightforward to install on a typical roof? The AS370-395M6-120 module measures 1756 × 1038 × 35 mm and weighs approximately 20.5 kg. This is a standard M6 format in a 120-cell configuration, compatible with the racking systems commonly used for pitched-roof installations. The sub-21 kg weight simplifies handling for installation crews and does not overstress standard roof truss structures. ### What is PERC technology in AmoSolar panels, and does it justify the price premium? PERC (Passivated Emitter Rear Contact) adds a passivation layer to the rear surface of the cell, reflecting photons that would otherwise pass through the silicon absorber layer and giving them a second opportunity to be converted into electrical energy. In practice, this translates to improved efficiency under diffuse light and overcast conditions — a meaningful benefit in Poland's climate. The AS370-395M6-120 series achieves module efficiency of up to 21.67%, which is a strong result for a standard monofacial format. ### Is the AmoSolar AS370-395M6-120 suitable for off-grid or hybrid installations? Yes, this series is explicitly recommended for hybrid and off-grid applications. A peak power output of up to 395 Wp, combined with stable performance under variable irradiance conditions thanks to PERC and half-cut technology, makes these modules well-suited for pairing with hybrid inverters and energy storage systems. The compact form factor also simplifies array sizing when matching panel count to the MPPT input specifications of off-grid inverters typically used in single-family homes. ### How does the AmoSolar AS370-395M6-120 series differ from newer bifacial panels? The AS370-395M6-120 is a monofacial module — it generates electricity exclusively from the front cell surface. Newer bifacial panels additionally harvest 10–25% more energy from light reflected off the ground or mounting surface, which makes sense on white facades or ground-mount systems with a high-albedo substrate. On a typical dark rooftop, however, bifaciality yields minimal gain, making the AS370-395M6-120 a practical and more cost-effective choice for rooftop installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/166-mono-half-cell-120cells-370-395w-1756-1039-35-9f70171658eb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +1.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +1.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +1.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +1.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +1.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +1.3 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +1.2 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +1.2 pp | | [AmoSolar AS370M6-120](https://comparepv.com/panel/amosolar-as370m6-120) | 370 W | -25 W, -1.4 pp | | [AmoSolar AS375M6-120](https://comparepv.com/panel/amosolar-as375m6-120) | 375 W | -20 W, -1.1 pp | | [AmoSolar AS380M6-120](https://comparepv.com/panel/amosolar-as380m6-120) | 380 W | -15 W, -0.8 pp | | [AmoSolar AS385M6-120](https://comparepv.com/panel/amosolar-as385m6-120) | 385 W | -10 W, -0.6 pp | | [AmoSolar AS390M6-120](https://comparepv.com/panel/amosolar-as390m6-120) | 390 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +3.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +3.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/amosolar-as395m6-120 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
