The use of large G12 format silicon wafers allows for achieving impressive power density while simultaneously reducing installation costs through a smaller number of required modules and structural components. The **bifacial double glass** construction makes the modules exceptionally resistant to extreme weather conditions and effectively captures energy reflected from the ground, which is crucial for professional large-scale projects. This series effectively solves the problem of energy loss at high temperatures thanks to its **low temperature coefficient**, guaranteeing stable operation even in full sun. This solution is dedicated primarily to investors building photovoltaic farms and large commercial installations, where maximizing yield from every square meter counts. Compared to traditional P-type modules, the NESE 66THB-G12 series offers **higher resistance to PID and LID degradation**, making it one of the most reliable long-term investments available on the Polish market. Thanks to the **use of SMBB technology**, these panels ensure better current flow and higher reliability, which clearly sets them apart from standard competition. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 700-750W\*\* median - 225.3 W/m² power density is 4.9 W/m² below \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 700-750W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #3982 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the New East Solar NESE 66THB-G12 and is it suitable for large commercial installations? The NESE 66THB-G12 series reaches a peak output of up to 715 Wp, placing it among the highest-density modules available in this format. The large G12 wafer size delivers exceptional power density per square meter, meaning fewer modules and mounting components are needed for utility-scale or large commercial projects. This directly reduces BoS costs and shortens installation time. ### What warranty does the New East Solar NESE 66THB-G12 series carry? The manufacturer provides a 12-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. The power warranty guarantees that the module retains a specified percentage of its original rated output after three decades of operation. The inherently low LID and PID degradation of N-type TOPCon cells makes these warranty figures realistic over the full warranty period. ### How does the TOPCon technology in the NESE 66THB-G12 compare to standard PERC panels? TOPCon (Tunnel Oxide Passivated Contact) uses N-type silicon with a thin tunnel-oxide passivation layer, achieving higher conversion efficiency and significantly lower light-induced degradation (LID) than P-type PERC cells. The NESE 66THB-G12 modules are therefore less susceptible to aging and maintain their rated power more reliably throughout the warranty period, resulting in higher energy yield and a lower LCOE over a 25-30 year project lifetime. ### Do the bifacial NESE 66THB-G12 panels deliver real gains in Northern European climate conditions? Yes, the bifacial double glass design generates measurable additional yield even in climates like Poland's, especially in ground-mounted utility installations. The rear side captures light reflected from grass, soil, snow, or light-colored surfaces, potentially boosting annual energy output by several percentage points depending on ground albedo. The double glass encapsulation also provides superior moisture resistance and durability in cold, humid conditions. ### Do the NESE 66THB-G12 panels suffer significant power loss on hot summer days? The NESE 66THB-G12 series features a low temperature coefficient, typical of N-type TOPCon cells. This means that for every degree Celsius rise in module temperature, the power loss is smaller than with standard PERC modules. In practice, this translates into higher energy yield on hot, sunny days — a critical advantage for both utility-scale solar farms and large industrial rooftop installations. ### Is New East Solar a reliable manufacturer, and where is the NESE 66THB-G12 series produced? New East Solar Energy is a Bloomberg NEF Tier 1 rated manufacturer, confirming its bankability and established presence in the global PV market. The company is headquartered in Cambodia. Tier 1 status simplifies project financing and is a standard requirement for bank and investment fund approval when funding utility-scale solar farms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1729755293204949-8985bf8a6a8e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | Cooler, lighter, +2.3 pp | | [New East Solar NESE 655-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-655-66mht-g12) | 655 W | Lighter, -1.4 pp, -5 yr warranty | | [New East Solar NESE 660-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-660-66mht-g12) | 660 W | Lighter, -1.3 pp, -5 yr warranty | | [New East Solar NESE 665-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-665-66mht-g12) | 665 W | Lighter, -1.1 pp, -5 yr warranty | | [New East Solar NESE 670-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-670-66mht-g12) | 670 W | Lighter, -1.0 pp, -5 yr warranty | | [New East Solar NESE 675-66MHT-G12](https://comparepv.com/panel/new-east-solar-nese-675-66mht-g12) | 675 W | Hotter, lighter, -5 yr warranty | | [New East Solar NESE 695-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-695-66thb-g12) | 695 W | Very close match | | [New East Solar NESE 705-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-705-66thb-g12) | 705 W | Very close match | | [New East Solar NESE 710-66THB-G12](https://comparepv.com/panel/new-east-solar-nese-710-66thb-g12) | 710 W | +10 W, +0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/new-east-solar-nese-700-66thb-g12 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
