Longi LR4-60HPB 350W Solar Panel (Black Mono PERC) – Half-Cut High Efficiency Module | 25-Year Performance Warranty

Description

Longi LR4-60HPB 350W Solar Panel – Efficient, Durable & Sustainable Energy Solution

The Longi LR4-60HPB 350W Solar Panel represents the perfect combination of advanced solar technology and modern engineering excellence. As part of LONGi’s renowned LR4 series, this panel is designed for users who demand superior performance, sustainable energy output, and maximum return on investment.

⚙️ High-Efficiency Mono PERC Technology

LONGi is a global leader in monocrystalline solar technology. The LR4-60HPB 350W utilizes Mono PERC (Passivated Emitter Rear Contact) cell design, which enhances light absorption and reduces recombination loss. This results in up to 19.2% module efficiency, ensuring optimal power generation even under low-light conditions.

Its half-cut design splits the panel into two independent halves, reducing resistive losses and minimizing the impact of partial shading. This innovative approach ensures higher performance stability in real-world environments, including Bangladesh’s humid and dusty conditions.

🔋 Advanced Engineering & Materials

The Longi LR4-60HPB 350W is built using Gallium-doped M10 wafers, which effectively eliminate Light-Induced Degradation (LID)—a common issue in conventional panels. With 9-busbar technology, current flows more efficiently through the cells, reducing power loss and improving reliability.

The Integrated Segmented Ribbon (ISR) enhances current distribution, ensuring higher energy yield per square meter. Together, these features result in a power-dense and long-lasting solar module that maintains stable performance for decades.

🌤️ Technical Specifications

🧱 Strong Build Quality for All Environments

LONGi’s superior manufacturing ensures every panel is mechanically robust and weather-resistant. The LR4-60HPB’s aluminum frame and anti-reflective tempered glass can withstand heavy wind loads and snow pressure, rated for up to 5400 Pa snow and 2400 Pa wind.

Its IP68-rated junction box provides enhanced water and dust protection, ensuring longevity even in Bangladesh’s coastal or high-humidity areas.

🌿 Eco-Friendly and Cost-Effective Energy

The Longi LR4-60HPB 350W is an excellent solution for those aiming to reduce their carbon footprint while lowering electricity costs. Its high conversion efficiency means you get more energy per square meter—ideal for rooftop installations where space is limited.

With its minimal degradation rate, this panel continues to produce over 84.8% of its original capacity even after 25 years, ensuring a reliable source of green energy for decades.
