Longi Solar Panels Bifacial Hi-MO 7 LR7-72HGD 560-590M 144 Cells Monocrystalline Double Glass PV module For large-scale On-Grid Solar System
The Longi Solar Panels Hi-MO 7 LR7-72HGD (560-590M) is a bifacial solar panel designed for on-grid solar systems, offering several advanced features that enhance its performance and efficiency. Here are the key aspects of this model:
Key Features
Power Output: The Longi Solar Panel Hi-MO 7 LR7-72HGD provides a power output range of 560 to 590 watts peak (Wp), making it suitable for large-scale solar installations.
Bifacial Technology: This Solar panel utilizes bifacial design, allowing it to capture sunlight from both the front and rear sides. This capability can increase energy generation, especially in environments with reflective surfaces, potentially providing up to 11% more energy yield compared to traditional monofacial panels under optimal conditions.
Cell Configuration: It consists of 144 monocrystalline cells, which optimize the panel’s efficiency and energy output.
High Efficiency: The panel achieves efficiencies of up to 22.8%, ensuring effective conversion of sunlight into electricity.
Durability: The double-glass construction enhances durability and resistance to environmental factors, such as moisture and dust, which can prolong the panel’s lifespan.
Temperature Coefficient: Approximately -0.28%/°C, indicating that the panel maintains good performance even in high-temperature conditions.
Dimensions and Weight: The panels typically measure around 2278 mm x 1134 mm x 30 mm and weigh approximately 31.8 kg, making them manageable for installation.
Warranty: Longi typically offers a 12-year product warranty and a 25-year linear power output warranty, ensuring long-term reliability and performance.
Advantages
Increased Energy Yield: The Longi Solar Panels bifacial design allows for energy capture from both sides, which can significantly enhance overall energy production, especially in suitable installation environments.
Cost-Effectiveness: Although bifacial panels may have a higher upfront cost, the increased energy output can lead to lower levelized cost of electricity (LCOE) over the panel’s lifespan, making them a cost-effective choice for large-scale projects.
Versatile Installation Options: Bifacial panels are ideal for ground-mounted systems, elevated installations, and locations where sunlight can reach both sides, such as carports or canopies. They are less effective when flush-mounted on roofs, where the rear side is shaded.
Robust Performance: The dual-glass design not only enhances durability but also improves performance in various weather conditions, including low-light scenarios.
Long-Term Reliability: The comprehensive warranty and low degradation rates provide assurance of sustained performance over the panel’s lifetime.
Applications
The Longi Solar Panels Hi-MO 7 LR7-72HGD is particularly well-suited for large-scale on-grid solar systems, including:
Utility-Scale Solar Farms: Its high efficiency and power output make it ideal for maximizing energy generation in large installations.
Commercial Installations: Businesses looking to reduce energy costs can benefit from the increased energy yield provided by bifacial technology.
Ground-Mounted Systems: The bifacial design is especially effective in installations where the rear side can receive reflected sunlight.
The Longi Solar Panels Hi-MO 7 LR7-72HGD bifacial solar panel represents a significant advancement in solar technology, combining high efficiency, durability, and enhanced energy production capabilities. Its design makes it an excellent choice for large-scale on-grid solar systems, providing both economic and environmental benefits.
