The large G12 wafer combined with Half-Cut cell technology and multi-busbar (MBB) interconnects reduce current density and resistive losses. - **Low temperature coefficient of -0.34%/°C** - 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. - **BNEF Tier 1 status – project bankability** - 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. - **Production outside China (Cambodia/Indonesia)** - 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). - **Bifacial design boosts energy yield** - 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. ## Cons - **PERC technology, not N-type TOPCon** - 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. - **Warranty below new premium standard** - 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. ## About this series 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. ## Notable figures - 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) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 650-700W\*\* median - At 33.5 kg, weight matches the \*\*PERC 650-700W\*\* median - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### What is the warranty on New East Solar NESE 675-66MHT-G12 panels? The NESE 675-66MHT-G12 comes with a 12-year product warranty covering defects in materials and workmanship, plus a 25-year linear power warranty. After 10 years the manufacturer guarantees at least 93.05% of rated output, and after 25 years at least 84.8% of 675 Wp — over 571 Wp. These are strong warranty terms for a utility-scale module in this power class. ### Are the NESE 675-66MHT-G12 panels bifacial, and how much extra energy does the rear side generate? Yes, the NESE 675-66MHT-G12 uses bifacial PERC cells that capture both direct front-side irradiance and albedo-reflected light from the rear. Depending on ground surface reflectivity — white gravel or light concrete being optimal — rear-side gain typically adds 10–20% to overall energy yield, meaningfully reducing LCOE on large-scale projects. ### What are the dimensions and weight of the NESE 675-66MHT-G12 — does it fit standard utility-scale racking? The NESE 675-66MHT-G12 measures 2384×1303×35 mm and weighs 33.5 kg. This is a standard G12 large-format footprint compatible with common steel and aluminum single-axis tracker and fixed-tilt racking systems. Structural engineers should account for module loads above 30 kg per unit. The module is too heavy and oversized for typical residential rooftop applications. ### How do NESE 675-66MHT-G12 panels perform during hot summer days — do they lose a lot of power? The power temperature coefficient (Pmax) of the NESE 675-66MHT-G12 is -0.34%/°C. At a cell temperature of 70°C — common on a sunny summer day — the module loses approximately 15.3% of STC-rated power. This is consistent with standard bifacial PERC module behavior and is within acceptable limits for commercial and utility-scale installations. ### Is New East Solar a reliable manufacturer — what does Tier 1 status mean for buyers of NESE 675-66MHT-G12 panels? New East Solar Energy, headquartered in Cambodia, holds Tier 1 status per BloombergNEF classification. This confirms the manufacturer has a documented bankability track record, consistent mass production capacity, and the financial standing required to honor long-term warranties. Tier 1 status is a key criterion in utility-scale project financing and procurement tenders. ### What types of installations are NESE 675-66MHT-G12 panels best suited for — can they be used on a residential rooftop? At 675 Wp and 33.5 kg, the NESE 675-66MHT-G12 is designed primarily for ground-mounted solar farms and large commercial systems where minimizing BoS costs and maximizing power density are the priority. Rooftop mounting is only feasible after a structural load assessment. For residential or small commercial rooftop systems below roughly 10 kWp, lighter modules in smaller formats are a more practical choice. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1729755465479109-616651fff611.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.5 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, +3.5 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, +3.3 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.3 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, +3.3 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, +3.2 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.1 pp | | [New East Solar NESE 655-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-655-66mht-g12) | 655 W | -20 W, -0.6 pp | | [New East Solar NESE 660-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-660-66mht-g12) | 660 W | -15 W, -0.5 pp | | [New East Solar NESE 665-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-665-66mht-g12) | 665 W | -10 W, -0.3 pp | | [New East Solar NESE 670-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-670-66mht-g12) | 670 W | Very close match | | [New East Solar NESE 695-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-695-66thb-g12) | 695 W | Cooler, heavier, +5 yr warranty | | [New East Solar NESE 700-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-700-66thb-g12) | 700 W | Cooler, heavier, +5 yr warranty | | [New East Solar NESE 705-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-705-66thb-g12) | 705 W | Heavier, +1.0 pp, +5 yr warranty | | [New East Solar NESE 710-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-710-66thb-g12) | 710 W | Heavier, +1.1 pp, +5 yr warranty | | [New East Solar NESE 715-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-715-66thb-g12) | 715 W | Heavier, +1.3 pp, +5 yr warranty | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +130 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/new-east-solar-nese-675-66mht-g12 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.
