Product Description: LONGi LR7-72HVH 630M Solar Panel

The LONGi LR7-72HVH 630M is a high-performance solar panel designed for commercial and industrial applications, delivering exceptional energy yield and reliable durability. Engineered using cutting-edge BC-Cell (Back Contact) technology combined with premium TaiRay wafer production, this 630-watt solar module offers superior efficiency, robust mechanical strength, and an extended lifespan, making it a top choice for sustainable energy solutions worldwide.

Unmatched Power Output and Efficiency

At the heart of the LR7-72HVH 630M lies its powerful 630 W maximum power output, achieved through advanced solar cell architecture and meticulous manufacturing processes. The module boasts a high module efficiency of 23.3%, significantly reducing the amount of space required to generate the same amount of electricity compared to conventional solar panels. This high efficiency stems from the innovative back contact (BC) cell design, which eliminates front-side wiring to maximize light absorption and minimize energy loss.

Advanced Cell Technology

The BC-Cell technology incorporated in the LR7-72HVH 630M places all electrical contacts on the rear side of the solar cells. This design reduces shading on the front surface, enhancing light absorption and boosting efficiency. Furthermore, the use of high-quality TaiRay wafers in the production process ensures superior crystal structure and electron mobility, resulting in higher energy conversion rates and improved panel performance under low light and high-temperature conditions.

Durable and Reliable Build

The LR7-72HVH 630M features a rugged build tailored for harsh environmental conditions. The module is constructed with a single 3.2mm coated tempered glass, which provides excellent resistance to impact and weather-related stress. The anodized aluminum alloy frame enhances structural integrity, supporting mechanical loads up to 5400 Pa on the front and 2400 Pa on the rear. This robustness ensures the panel withstands snow loads, wind pressure, and even hail impacts (tested against 25mm hailstones traveling at 23 m/s).

Weighing just 28.5 kg and measuring 2382 × 1134 × 30 mm, the panel balances lightweight design with structural strength, allowing for easier installation and compatibility with a variety of mounting systems.

Industry-Leading Warranty and Certifications

LONGi backs the LR7-72HVH 630M with a comprehensive 15-year warranty covering materials and workmanship and an outstanding 30-year linear power output warranty, ensuring less than 0.35% power degradation annually after the first year. These warranties reflect the confidence in product longevity and consistent energy production.

The panel meets stringent international certifications, including IEC 61215, IEC 61730, UL 61730, ISO9001:2015 Quality Management, ISO14001 Environmental Management, and ISO45001 Occupational Health and Safety standards. Additionally, it complies with IEC62941 guidelines for module design qualification and type approval, guaranteeing safety and reliability in a broad range of applications worldwide.

Optimized Performance in Real-World Conditions

The LR7-72HVH 630M is engineered to maintain optimal performance across diverse environmental conditions. The nominal operating cell temperature (NOCT) is approximately 45±2°C, which means the module efficiently handles elevated temperatures without significant power loss. Its temperature coefficients further underline its robustness: a minimal +0.05%/°C for short-circuit current (Isc), -0.20%/°C for open-circuit voltage (Voc), and -0.26%/°C for maximum power (Pmax).

Operating effectively from -40°C to +85°C, this solar panel is suitable for use in extreme climates, from scorching deserts to freezing high altitudes, making it a versatile choice for global solar projects.

Bifacial Design and Enhanced Energy Harvest

The LR7-72HVH 630M utilizes a bifacial design that captures sunlight from both the front and rear sides of the panel, increasing overall energy generation by up to 25% depending on installation conditions. This feature is especially beneficial for installations on reflective surfaces such as concrete, white roofs, or sandy grounds.

This bifaciality not only enhances the energy yield but also contributes to lower operating temperatures, improving the panel’s lifespan and reliability over time.

Installation and System Compatibility

Designed with practicality in mind, the LR7-72HVH 630M features a junction box rated at IP68 protection with three bypass diodes, ensuring efficient current flow even when partially shaded. The output cable has a cross-section of 4 mm² and customizable lengths, offering flexible installation options.

The panel supports a maximum system voltage of 1500 V DC, allowing for larger system designs with fewer strings and reduced balance-of-system (BOS) costs. The maximum series fuse rating is 25 A, ensuring safe and compliant system integration.

Environmental Responsibility

LONGi’s commitment to sustainability is reflected in the LR7-72HVH 630M’s compliance with ISO14001 Environmental Management standards, emphasizing eco-friendly manufacturing processes. The solar module not only helps reduce carbon footprints by generating clean renewable energy but is also produced with a focus on minimizing environmental impact throughout its lifecycle.

Summary

The LONGi LR7-72HVH 630M solar panel is an exceptional choice for commercial and industrial solar installations requiring high efficiency, durability, and reliable long-term performance. With cutting-edge BC-Cell technology, robust materials, and industry-leading warranties, it promises a sustainable energy solution that maximizes power output while ensuring safety and durability under harsh environmental conditions. Whether for rooftop or ground-mounted arrays, this module’s combination of power, efficiency, and durability supports ambitious renewable energy goals worldwide.
