This simplifies precise system design and removes the risk of underestimating energy yield, unlike modules with symmetric (+/-3%) tolerance. - **PID resistance** - Confirmed resistance to Potential Induced Degradation protects against power loss caused by leakage currents - especially relevant in large ground-mount and industrial systems, where higher string voltages increase PID risk. - **25-year power warranty** - The manufacturer backs the series with a 25-year progressive power warranty and a 12-year product warranty - parameters in line with Tier-1 industry standards, giving investors predictability of returns over the long term. - **Certified mechanical load resistance** - The design has been tested for high mechanical loads (snow, wind) and paired with an IP67/IP68 junction box and MC4-compatible connectors, ensuring reliable operation in harsh weather and easy integration with existing BoS equipment. ## Cons - **Efficiency below segment median** - The 16.66-16.92% efficiency range is the lowest among comparable 330 Wp models: Jinko's 72 Series Poly reaches 17%, Waaree's ARKA Series 19.81%, and JA Solar's Monocrystalline80 as much as 23.15%. At the same power rating, IM72 requires more roof or ground area than newer monocrystalline designs. - **Legacy multi-Si tech, no bifacial variant** - The series is built on 72 multicrystalline cells introduced in 2011 and offers no bifacial variant, while Motech itself is now developing n-type TOPCon (26.5%) and HJT (26.3%) cells in the lab - IM72 no longer reflects the manufacturer's current state of the art. - **Manufacturer financial pressure** - Motech reported a net loss of approximately NT$1.35 billion (US$41.8 million) in Q2 2024 amid a >50% year-over-year drop in solar cell prices. While the company remains operational, its financial position raises questions about long-term service backing under the 25-year power warranty. ## About this series The Motech IM72 series consists of photovoltaic modules built on 72 multicrystalline solar cells connected in series, designed for commercial installations and larger rooftop systems where long-term output stability matters most. The series stands out with its **positive power tolerance**, ensuring the module's actual parameters never fall below the rated values, which simplifies precise system design and minimizes the risk of underestimating energy yield. The panels feature **verified resistance to PID degradation**, protecting against power loss caused by leakage currents, a common issue in large ground-mounted and industrial systems. The frame and glass construction has been tested against high mechanical loads, making the series well suited for regions with heavy snowfall and strong wind exposure. The manufacturer backs the modules with a **25-year progressive power warranty** along with a 12-year materials and workmanship warranty, giving investors confidence in long-term return on investment. A sealed IP67/IP68 junction box with three bypass diodes ensures reliable operation even in harsh weather conditions, while MC4-compatible connectors simplify installation and integration with existing BoS equipment. The IM72 series is a strong fit wherever the priority is predictable, multi-year energy production with limited service risk. ## Notable figures - At 16.9% efficiency, this panel is 4.9pp below the \*\*database\*\* median of 21.8% - At 169.2 W/m², this panel generates 48.9 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - Temperature coefficient of -0.42%/°C is 0.12pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - Weight of 23.0 kg (3.5 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - In the top 96% for efficiency among all N-type panels ## Questions ### What is the maximum power output of the Motech IM72 series panel? The IM72 series modules reach a maximum power of up to 330 Wp. Built with 72 multicrystalline cells connected in series, this configuration delivers higher operating voltage, making the panel primarily suited for commercial installations and larger rooftop systems rather than typical residential microinstallations. ### Are Motech IM72 panels resistant to PID degradation? Yes, the IM72 series has confirmed resistance to PID (potential-induced degradation). This protects against power loss caused by leakage currents, a common issue in large ground-mounted and industrial installations operating at high system voltages. ### What warranty comes with Motech IM72 modules? The manufacturer provides a 12-year product (materials) warranty and a 25-year progressive power warranty. A positive power tolerance means actual module output never falls below the rated nameplate values, which simplifies precise energy yield planning and increases investment certainty over the long service life. ### Can Motech IM72 panels withstand heavy snow and wind loads? Yes, the IM72 series has been tested for high mechanical loads, making it suitable for regions with heavy snowfall and strong winds. This makes the modules well-suited for both commercial rooftops and larger ground-mounted installations exposed to harsh weather conditions. ### What ingress protection rating does the IM72 junction box have? The junction box meets the IP67/IP68 standard and includes three bypass diodes, ensuring reliable operation even in humid or wet conditions. MC4-compatible connectors simplify installation and integration with existing wiring and BoS components in the system. ### Are Motech IM72 modules bifacial panels? No, the IM72 series consists of monofacial panels based on the classic configuration of 72 multicrystalline cells connected in series. Their key strength is not rear-side energy generation but stable, predictable output and high resistance to degradation over long-term operation in commercial installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/IM72CB_197099040mmEN_20200511-6ce6eb7e35a9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | Cooler, lighter, +3.2 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | Cooler, lighter, +3.0 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | Cooler, +3.0 pp, +5 yr warranty | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | Cooler, lighter, +2.9 pp | | [Canadian Solar CS3L-365P](https://comparepv.com/panel/canadian-solar-cs3l-365p) | 365 W | +35 W, cooler, +2.8 pp | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | Cooler, lighter, +2.7 pp | | [Canadian Solar CS3L-360P](https://comparepv.com/panel/canadian-solar-cs3l-360p) | 360 W | +30 W, cooler, +2.6 pp | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | Cooler, lighter, +2.6 pp | | [Motech IM72CB-325](https://comparepv.com/panel/motech-im72cb-325) | 325 W | -0.3 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +7.1 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +6.8 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +6.6 pp, +15 yr warranty | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | Cooler, +5.9 pp, +15 yr warranty | | [Maxeon SPR-MAX6-435](https://comparepv.com/panel/maxeon-spr-max6-435) | 435 W | Cooler, +5.6 pp, +15 yr warranty | | [Lina Energy LEPV 132 ULTRA PREMIUM BLACK 440Wp (LEPV 440)](https://comparepv.com/panel/lina-energy-lepv-132-ultra-premium-black-440wp-lepv-440) | 440 W | +110 W, cooler, +5.4 pp | | [JA Solar NS-420MH-80](https://comparepv.com/panel/ja-solar-ns-420mh-80) | 420 W | +90 W, cooler, +5.4 pp | --- Source: https://comparepv.com/panel/motech-im72cb-330 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
