Questions about this pairing
Which panel is better: Longi Solar LR5-72HBD-540M or GCL GCL-M10/72GDF-B-540?
According to our database: Longi Solar LR5-72HBD-540M has higher module efficiency (20.90% vs 20.60%); Longi Solar LR5-72HBD-540M tolerates heat better (temp coeff -0.340%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR5-72HBD-540M and GCL GCL-M10/72GDF-B-540?
Longi Solar LR5-72HBD-540M has a module efficiency of 20.90%, while GCL GCL-M10/72GDF-B-540 is 20.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR5-72HBD-540M use vs GCL GCL-M10/72GDF-B-540?
Longi Solar LR5-72HBD-540M uses Monocrystalline cells; GCL GCL-M10/72GDF-B-540 uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Longi Solar LR5-72HBD-540M and GCL GCL-M10/72GDF-B-540?
Longi Solar LR5-72HBD-540M has a 30 years power warranty; GCL GCL-M10/72GDF-B-540 has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Longi Solar LR5-72HBD-540M and GCL GCL-M10/72GDF-B-540 bifacial panels?
Both Longi Solar LR5-72HBD-540M and GCL GCL-M10/72GDF-B-540 are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
