Efficiency leader, short guarantee
The Neo Solar Power NESE 655-675-66MHT-G12 series consists of modules designed for large-scale installations, where high power density and quick assembly are crucial. The use of monocrystalline cells in G12 format allows for greater energy generation from fewer modules, which simplifies string design and reduces the number of DC connections. A key advantage of this series is bifacial technology - the panel operates not only from the front, but also utilizes reflected light from the ground, which effectively increases energy generation in suitable conditions (bright ground, gravel, roofs with membranes).
In practice, the NESE 655-675-66MHT-G12 series solves the BOS cost problem: fewer modules mean fewer structures, cabling, and a shorter installation time. It also contributes to more stable operation due to resistance to losses under partial shading, which is typical for modern cell connections. This is a good choice for PV farms, carports, and C&I projects, where maximizing energy output on a limited area and overall life-cycle cost-effectiveness are important.

655-675 Wp output from G12-format (132 half-cut) cells delivers more energy per module than older M10 formats, shortening strings, reducing DC connections, and lowering BoS costs in large ground-mount and C&I installations.
The 21.09-21.73% efficiency range is on par with direct 675 W-class peers - Q-Cells Q.PEAK DUO ML-G12S (21.7%), BYD AURO MSTK-33 (21.73%), and Trina Vertex TSM-DE21 (21.7%) - so despite not being a Tier-1 bankable manufacturer, the panel is technically competitive with the top of the segment.
Dual-side generation captures light reflected from the ground surface (gravel, roofing membrane, light-colored soil), adding a real energy uplift beyond front-side nameplate power under typical ground-mount or carport conditions.
The datasheet (2384-1303-35 V2.1) guarantees 93.05% power after 10 years and 84.8% after 25 years - a standard linear degradation level for PERC technology, comparable to warranties offered by Trina and Q-Cells in this segment.
Neo Solar Power has operated in the PV market since 2005, and the NESE 655-675-66MHT-G12 series (released 2021, still active) is produced at the New East Solar Energy facility in Cambodia, giving it a longer manufacturing track record than many newer G12 module suppliers.
Neo Solar Power does not appear on the BNEF Tier 1 list for PV modules, unlike peers such as Trina Solar and Q-Cells - this can complicate project financing for banks that require Tier-1 bankability as a lending condition.
PERC cells have a higher LID/LeTID degradation coefficient and weaker high-temperature performance than newer N-type TOPCon/HJT cells, which by 2026 already dominate Tier-1 manufacturer lineups at comparable 655-675 W power levels.
The 12-year product warranty is shorter than the 15-year standard now offered by many Tier-1 manufacturers (e.g. Trina, Q-Cells) in the 675 W power class, which may affect risk assessment for projects with a 25+ year horizon.
- At 21.7% efficiency, this panel is on par with typical PERC 650-700W modules
- Power density of 217.3 W/m² packs 4.8 W/m² more into the same footprint vs PERC 650-700W median (212.5 W/m²)
- At -0.34%/°C, hot weather performance is typical for PERC 650-700W panels
- At 33.5 kg, weight matches the PERC 650-700W median
- 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces
