Features of Longi Solar Panels
LONGi solar panels stand out for their advanced technology and high efficiency, ensuring that homeowners and businesses enjoy maximum energy output. Some of the key features that make LONGi solar panels a top choice include the following:
Positive Power Tolerance: LONGi solar panels come with a positive power tolerance of 0 ~ +5W, ensuring that customers receive up to 5W more power than the rated panel output. This positive tolerance means higher energy production over the lifetime of the system, increasing return on investment.
High Conversion Efficiency: With up to 20.9% conversion efficiency, LONGi solar panels ensure optimal energy capture from the sun, even in regions with less sunlight or during cloudy days. This high efficiency ensures more electricity generation, reducing reliance on the grid and lowering energy costs.
Low LID Mono PERC Technology: LONGi solar panels utilize Mono PERC (Passivated Emitter Rear Cell) technology, which significantly reduces Light Induced Degradation (LID). This means that the power loss in the first year is kept under 2%, and degradation is limited to 0.55% per year for the next 25 years, ensuring long-term efficiency.
Strong PID Resistance: Potential Induced Degradation (PID) can significantly reduce the performance of solar panels over time. LONGi’s panels are designed with strong PID resistance, thanks to their advanced solar cell manufacturing process and optimized Bill of Materials (BOM), ensuring consistent performance and a longer lifespan.
Reduced Resistive Loss: LONGi solar panels are designed with lower operating current, which leads to reduced resistive loss. This means more energy is converted into usable electricity rather than lost as heat, contributing to a higher overall energy yield.
Hot Spot Risk Reduction: LONGi panels feature an optimized electrical design that reduces the risk of hot spots—a common problem in solar panels that can lead to damage and lower efficiency. Their design ensures a more reliable performance throughout the life of the system.
Warranties and Reliability: LONGi solar panels come with a 12-year product warranty and a 25-year performance warranty, ensuring that your system will continue to perform at peak efficiency for many years. These warranties offer peace of mind as the company stands behind the quality of its panels.
Tier 1 Panels: LONGi solar panels are recognized as Tier 1 products, which is the highest classification in the solar industry. Tier 1 panels are known for their quality, reliability, and long-term performance, making them a trusted choice for solar installations worldwide.
