7. FAQ
Q1: What is the standard polycrystalline solar panel size you offer, and can it be customized?
A: Our standard panel dimensions are 1960mm x 992mm x 40mm, which is an industry-common size for modules in the 370W-400W range. Yes, we provide OEM/ODM services and can discuss customization of dimensions, power output, and other features based on your project's specific needs and volume.
Q2: How do polycrystalline panels compare to monocrystalline in terms of efficiency and cost?
A: Monocrystalline panels typically have a slightly higher efficiency (1-2% more). However, polycrystalline panels offer a more cost-effective solution, especially for large-scale installations where space is less constrained. The lower cost per watt often results in a better overall return on investment for commercial and utility projects.
Q3: What warranties do you provide?
A: We provide a comprehensive warranty package: a 12-year product warranty on materials and workmanship, and a 25-year linear performance warranty that guarantees at least 80% of the original rated power output at the end of the warranty period.
Q4: Are your panels suitable for harsh coastal environments?
A: Absolutely. Our panels feature corrosion-resistant anodized aluminum frames and are manufactured with high-grade encapsulants and backsheets. They are certified to withstand salt mist corrosion, making them an excellent choice for coastal and high-humidity regions.
Q5: What is the typical lead time for a container order?
A: For standard models, the lead time is typically 15-25 days after receiving deposit and confirmed order. We maintain a strategic inventory and efficient production scheduling to ensure timely delivery. Exact lead times can be confirmed based on current order volume and destination port.
