Light for its output, short guarantee
New East Solar photovoltaic panels from the NESE 675-66MHT-G12 series represent a breakthrough in the efficiency of large-scale installations, utilizing state-of-the-art N-type TOPCon cells based on the G12 silicon wafer. This advanced design effectively eliminates the problem of limited mounting space, offering extremely high power from a single module. Thanks to the use of Half-Cut cell technology and multi-busbar (MBB) connections, these modules minimize resistance losses and demonstrate excellent resistance to micro-cracks. This series is dedicated primarily to demanding investors building solar farms and large commercial systems, where lowering structural BOS costs is key. A standout feature compared to the competition is the exceptionally low temperature coefficient, which allows for generating stable yields even on hot days when standard panels lose efficiency. By choosing this model, you gain a product with enhanced resistance to light-induced and voltage-induced degradation, which translates into a longer return on investment and trouble-free operation for decades. This solution combines maximum power density with an innovative approach to material durability, setting new standards in the large-area module segment.

The module delivers up to 675 Wp at 21.73% efficiency, matching the best models in the segment (BYD AURO MSTK-33, Neo Solar Power NESE 655-675-66MHT-G12 – both 21.73%) and outperforming the Q.PEAK DUO ML-G12S (21.7%). The large G12 wafer combined with Half-Cut cell technology and multi-busbar (MBB) interconnects reduce current density and resistive losses.
Per the manufacturer's official datasheet, the Pmax temperature coefficient is -0.34%/°C, limiting output losses on hot days — a meaningful advantage for large ground-mount installations in high-irradiance climates.
New East Solar is listed as a Tier 1 manufacturer under the BloombergNEF methodology, easing bank financing for large-scale solar farms and commercial systems — a key requirement for institutional investors.
Headquarters and part of production are based outside China (Cambodia, with a manufacturing facility in Batam, Indonesia), giving a cost advantage over mainland Chinese producers when exporting to markets with anti-dumping tariffs on Chinese modules (e.g., the US).
The bifacial construction allows additional rear-side generation with appropriate mounting (e.g., on bright ground albedo or trackers), a common premium feature in utility-scale projects that raises total annual energy yield without increasing footprint.
The official datasheet (nesolar.com.kh) confirms P-type PERC cells, not the N-type TOPCon suggested in some marketing materials. PERC is more susceptible to LID/LeTID degradation and has a lower efficiency ceiling than newer N-type TOPCon modules, which competitors in the same power class are increasingly offering.
The 12-year product and 25-year power warranty is still typical for PERC, but clearly shorter than the 30-year linear warranties already offered by some Tier-1 manufacturers on N-type modules in the same power range (655-675 Wp), which can affect lifecycle-cost (LCOE) comparisons.
- At 21.6% efficiency, this panel is on par with typical PERC 650-700W modules
- At 215.7 W/m² power density, this panel generates 3.2 W/m² more per unit area than PERC 650-700W median (212.5 W/m²)
- Temperature coefficient of -0.34%/°C matches the PERC 650-700W median
- Weight of 33.5 kg is typical for PERC 650-700W panels
- Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof
