Engineered with ultra-high transmittance double tempered glass and advanced N-type cells for maximum double-sided power yield in high-albedo environments.
Sylhet Division, renowned for its extensive tea estates, growing textile industry, and the Sylhet Hi-Tech Park, presents unique environmental parameters requiring specialized PV engineering.
Sylhet produces over 80% of Bangladesh’s tea output across regions like Sreemangal and Habiganj. Tea processing factories operate high-load thermal and electrical machinery. Dual-glass bifacial modules installed on factory roofs or ground mount micro-grids offset peak electricity tariffs while enduring dense organic dust and high humidity.
With an average annual rainfall exceeding 4,000 mm and persistent relative humidity above 80%, standard single-glass polymer backsheet modules experience accelerated degradation (PID and moisture delamination). Dual-glass architecture with POE encapsulant guarantees zero water vapor transmission.
Sylhet's river basins, sandy soils along the Surma and Kushiyara rivers, and reflective industrial roof coatings offer excellent rear-side albedo. Bifacial dual-glass modules capture reflected irradiance from below, adding up to +25% additional yield.
As a leading solar products manufacturer, Anhui Ran Solar Co., Ltd. specializes in the research, development, production, and global sales of high-quality solar PV products. Since our establishment in 2011, Anhui Ran Solar has achieved remarkable milestones, surpassing many competitors in production capacity, innovative designs, and technological advancements. We firmly believe that innovation drives progress, and we continually pursue new technologies and higher efficiencies to empower a sustainable energy future.
Currently, Anhui Ran Solar boasts a global production capacity of 7.5 GW, serving customers across more than 80 countries with premium products and professional services. By the end of 2023, over 15 GW of our solar modules have been deployed worldwide, powering residential, commercial, and utility-scale projects.
A rigorous technical breakdown comparing standard monofacial single-glass modules against Anhui Ran Solar’s N-Type TOPCon Double-Glass modules.
| Performance Feature | Standard Monofacial (Single Glass) | Anhui Ran Dual-Glass Bifacial (N-Type) | Advantage for Sylhet Buyers |
|---|---|---|---|
| Rear Side Power Gain | 0% (Opaque Backsheet) | +10% to +30% (Depending on Albedo) | Significantly higher ROI on reflective roofs & ground mount setups. |
| Encapsulation & Moisture Resistance | EVA + Tedlar (Permeable to moisture) | Double 2.0mm/2.5mm Tempered Glass + POE | Zero water vapor ingress, preventing internal corrosion during Sylhet monsoons. |
| PID / LeID Susceptibility | Moderate to High degradation in heat | Zero PID / LeID (N-Type TOPCon Cell) | Stable year-on-year energy yield without power drop-off. |
| Temperature Coefficient | -0.35% / °C | -0.29% / °C | Higher power output during hot, humid summer days in Sylhet (35°C+). |
| Fire & Mechanical Load Class | Class C Fire Rating, 2400Pa Wind Load | Class A Fire Rating, 5400Pa Snow / 2400Pa Wind | Maximum physical integrity against tropical storms and industrial hazards. |
Dual-glass structures place the solar cell matrix at the neutral axis of stress. Unlike single-glass panels that warp under asymmetric thermal expansion, double-glass modules remain completely flat, eliminating micro-cracking during extreme weather events in Sylhet.
Sylhet's agricultural processing facilities and chemical processing zones generate airborne acidic and alkaline fumes. The outer glass layers provide inert chemical protection, preventing surface clouding and chemical erosion.
Combining automated robotics with rigorous patent-backed processes to deliver defect-free solar panels worldwide.
