**Efficiency matching segment leaders** - Maximum efficiency of 23.23% matches the best comparable models (Lexron 144 Cell Halfcut TOPCon – 23.23%, Tongwei TWMND 72HD – 23.2%) and clearly exceeds Talesun BISTAR TP7F78M (21.5%), translating into higher energy yield per square meter of roof. - **N-type TOPCon technology** - N-type cells limit light-induced degradation (LID) and offer a better temperature coefficient than older P-type/PERC technologies, meaning less power loss on hot days and more stable output over the module's lifetime. - **Bifacial design boosts energy yield** - The bifacial construction captures additional energy from ground albedo reflection, particularly valuable on light-colored roofs or ground-mount installations — an added benefit not available with standard monofacial modules. - **High unit power thanks to M10 wafers** - The 580–600 Wp power range paired with M10 wafer size delivers a strong power-to-area ratio, useful where roof space is limited on residential and commercial buildings — fewer modules are needed to reach the target system power. - **30-year linear power warranty** - The manufacturer specifies a 30-year power output warranty, matching the current N-type segment trend and exceeding the standard 25 years offered by many P-type module manufacturers. ## Cons - **Production discontinued** - The M10 MONO MODULE N-TYPE series has been discontinued, meaning limited availability of additional units for future system expansion and potential difficulties with warranty service and spare-part access down the line. - **Powitt Solar not on the BNEF Tier-1 list** - The manufacturer does not appear on the Bloomberg New Energy Finance Tier-1 bankable list, which can complicate bank financing for larger commercial projects and raise concerns among institutional investors about long-term supplier stability. - **Shorter product warranty vs. market leaders** - The 15-year product warranty is shorter than the 25-year standard now offered by leading Tier-1 manufacturers, which combined with the discontinued production increases risk for investors relying on full service support over the system's lifetime. ## About this series The Powitt Solar M10 MONO MODULE N-TYPE series represents a technological leap in the efficiency of photovoltaic installations, based on **advanced N-type cells**. The use of this technology allows for a significant reduction in light-induced degradation (LID), which translates into a longer service life and stability of energy production throughout the entire life cycle of the power plant. Thanks to the use of M10 size wafers, these modules offer an optimal power-to-surface ratio, solving the problem of limited mounting space on the roofs of residential and commercial buildings. A key differentiator of the series is its **exceptional performance in low-light conditions**, which in the Polish climate ensures real energy gains even on cloudy days or in the early morning. The use of **TOPCon** technology guarantees an excellent temperature coefficient, thanks to which the panels maintain high efficiency even during summer heat. This solution is dedicated to investors seeking **maximization of self-consumption** and a quick return on investment thanks to higher efficiency than in the case of standard P-type modules. This series stands out from the competition with its precise production process that minimizes the risk of micro-cracks, making it an ideal choice for demanding industrial projects and modern single-family homes focusing on energy independence. ## Notable figures - At 22.4% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - At 224.5 W/m² power density, roof space requirements are typical for \*\*N-type 550-600W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 31.0 kg is 1.5 kg above \*\*N-type 550-600W\*\* median (29.5 kg) - verify structural support - In the top 33% for efficiency among all N-type panels ## Questions ### What is the warranty on the Powitt Solar M10 MONO MODULE N-TYPE series? The manufacturer provides a 15-year product warranty and a 30-year linear power warranty. This means the panel is guaranteed to maintain a minimum power output level for three decades. The N-type cell technology with reduced light-induced degradation (LID) supports long-term energy production stability, making the power warranty realistically achievable under everyday operating conditions. ### What is TOPCon technology and why is it worth choosing in the Powitt Solar M10 MONO MODULE N-TYPE series? TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type cell technology that reduces charge recombination losses at the cell surface. In practice, this results in a better temperature coefficient than PERC modules, meaning panels lose less power during summer heat. The M10 MONO MODULE N-TYPE series reaches a maximum power output of up to 600 Wp, making it an efficient choice for both rooftop and ground-mounted installations. ### Are the Powitt Solar M10 MONO MODULE N-TYPE modules bifacial, and what are the practical benefits? Yes, the M10 MONO MODULE N-TYPE series consists of bifacial modules. The rear side of the panel harvests energy from light reflected off the ground or rooftop surface. With a bright substrate — gravel, snow, or a white reflective membrane — this can increase annual energy yield by several to over ten percent. The effect is most pronounced in ground-mounted systems and flat-roof installations with a reflective coating. ### How do Powitt Solar M10 MONO MODULE N-TYPE panels perform on cloudy days typical of the Polish climate? The N-type cells used in this series feature exceptional low-light performance. On overcast days, at dawn, and at dusk, the M10 MONO MODULE N-TYPE modules generate proportionally more energy than standard P-type modules. In Polish climatic conditions, where annual peak sun hours are limited, this translates into a measurably higher annual energy yield from the same roof area. ### How does the M10 MONO MODULE N-TYPE series differ from popular P-type PERC modules? N-type cells exhibit significantly lower light-induced degradation (LID) compared to P-type PERC modules. This means less power loss in the early years of operation and more stable energy production throughout the 30-year power warranty period. The superior temperature coefficient of TOPCon technology also results in a more favorable energy balance on hot summer days. ### Is the Powitt Solar M10 MONO MODULE N-TYPE series still available for purchase? The Powitt Solar M10 MONO MODULE N-TYPE series has been discontinued and is no longer actively distributed. Limited stock may still be available at select distributors, but new manufacturer orders are not being fulfilled. If you need comparable N-type TOPCon technology with assured long-term service availability, it is worth considering currently produced series with similar specifications. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2025-2-8-powitt-182mm-144half-cell-580-600w-ntype-bd-535bbdc6769e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [Powitt Solar PW-72M585MH10-BD](https://comparepv.com/panel/powitt-solar-pw-72m585mh10-bd) | 585 W | Very close match | | [Powitt Solar PW-72M590MH10-BD](https://comparepv.com/panel/powitt-solar-pw-72m590mh10-bd) | 590 W | +10 W, +0.4 pp | | [Powitt Solar PW-72M595MH10-BD](https://comparepv.com/panel/powitt-solar-pw-72m595mh10-bd) | 595 W | +15 W, +0.6 pp | | [Powitt Solar PW-72M600MH10-BD](https://comparepv.com/panel/powitt-solar-pw-72m600mh10-bd) | 600 W | +20 W, +0.8 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/powitt-solar-pw-72m580hm10-bd Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
