Middle of its segment, weak in heat
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.

IM72 modules carry a positive-only power tolerance, meaning actual output never falls below the rated value (325-330 Wp). This simplifies precise system design and removes the risk of underestimating energy yield, unlike modules with symmetric (+/-3%) tolerance.
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.
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.
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.
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.
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.
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.
- At 16.7% efficiency, this panel is 5.2pp below the database median of 21.8%
- 166.6 W/m² power density is 51.5 W/m² below database median (218.1 W/m²) - requires larger installation area
- At -0.42%/°C, loses 0.12pp more power per degree than database median (-0.30%/°C)
- 23.0 kg weight - 3.5 kg lighter than database median (26.5 kg), reducing installation effort
- Ranked #13653 out of 14129 panels for efficiency in the database
