LONGi Hi-MO 7 610W Bifacial Solar Panel (LR7-72HGD-610M) – Bangladesh

Description

The LONGi Hi-MO 7 610W Bifacial Solar Panel is the latest high-performance innovation from LONGi Solar, the world’s leading solar technology manufacturer. Built with Hybrid Passivated Dual-Junction Cell (HPDC) technology, this solar module delivers outstanding energy yield, even in the most demanding climates like Bangladesh.

Designed for utility-scale solar farms, commercial rooftops, industrial facilities, and agricultural projects, the Hi-MO 7 offers 22.6% efficiency, bifacial power generation, and a 30-year linear warranty — ensuring reliable energy output over decades.

The panel’s bifacial architecture allows sunlight absorption from both the front and rear sides, delivering up to 3% more total energy output compared to monofacial modules. This makes it an excellent choice for maximum return on investment (ROI) and lower Levelized Cost of Energy (LCOE).

🌟 Key Features & Advantages

✅ 1. Maximum Energy Yield

LONGi’s HPDC technology ensures exceptional performance under all light conditions — from early morning to cloudy afternoons. Combined with bifacial energy gain, it provides more kilowatt-hours per installed watt throughout the year.

✅ 2. Superior Efficiency

With a 22.6% conversion efficiency, Hi-MO 7 delivers high output from a compact module footprint, ideal for space-constrained installations.

✅ 3. Bifacial Design = Dual-Side Power

The bifacial glass-on-glass design allows the rear side to harvest reflected sunlight, boosting total energy generation by up to 3% compared to monofacial panels.

✅ 4. Strong & Durable

Built with 2.0mm dual tempered glass and a 30mm anodized aluminum frame, the module withstands Bangladesh’s humid, saline, and dust-heavy environments.

✅ 5. Long-Term Reliability

30-year linear power warranty ensures long-term stability with only 0.4% annual degradation. This guarantees ≥87% rated power output after 30 years.

✅ 6. Lower System Costs (BOS Savings)

Higher power density reduces the total number of panels, mounts, and wiring needed — lowering Balance of System (BOS) costs and simplifying logistics.

🔬 HPDC Cell Technology Explained

HPDC (Hybrid Passivated Dual-Junction Cell) combines advanced passivation layers on both sides of the solar cell to reduce electron recombination and energy loss.

Key Benefits:

• Increased voltage & current

• Lower degradation over time

• Improved low-light performance

• Better resistance to Potential-Induced Degradation (PID)

• Enhanced reliability in hot, humid climates

This technology is particularly effective in tropical conditions — making it perfect for Bangladesh.

☀️ Performance in Bangladesh

The LONGi Hi-MO 7 610W Bifacial Solar Panel is engineered for high-yield operation in the tropical climate of Bangladesh:

• Anti-PID and LID resistant cells ensure consistent long-term energy generation.

• Temperature coefficient of -0.28%/°C maintains performance during peak summer heat.

• Bifacial architecture takes advantage of Bangladesh’s reflective ground surfaces — such as concrete, tin rooftops, and sandy soil.

• High mechanical load capacity ensures resilience during storms and heavy wind conditions.

🧮 Estimated Energy Generation

In Bangladesh (average solar irradiance 4.7–5.0 kWh/m²/day):

• Per panel annual output: ~1,050 – 1,200 kWh

• 100-panel (61kW) system: 105,000 – 120,000 kWh/year

• System lifespan: 30+ years with 87% performance retention

---

🔋 Energy Yield Advantage (Bifacial Bonus)

Because of its bifacial design, the LONGi Hi-MO 7 can capture reflected sunlight from ground or rooftop surfaces. Depending on site reflectivity (albedo), bifacial gain can add:

• +1.5% on green field sites

• +2.5% on white roofs or concrete surfaces

• +3.0% on reflective metal/tin rooftops

This translates into thousands of extra kilowatt-hours annually in real-world installations.
