    Frequently Asked Questions
    Q What is the difference between N-type and P-type solar panels in the 600–620W range?
    N-type panels generally offer higher efficiency, better performance in high-temperature conditions, and lower degradation rates compared to P-type panels. P-type panels remain a cost-effective option for many utility-scale projects. Both types are available within our 600–620W portfolio depending on the brand and model selected.
    Q Why are 600–620W panels more economical for large-scale solar projects?
    Higher-wattage panels reduce the total number of modules required for a given project capacity. This directly lowers balance-of-system (BOS) costs including mounting structures, cabling, labor, and long-term operations and maintenance. Combined with 1500V system compatibility, the 600–620W class delivers a lower levelized cost of energy (LCOE) for utility-scale installations.
    Q Are these panels suitable for coastal or agricultural environments?
    Yes. Our 600–620W panels are tested and certified for salt mist and ammonia resistance, making them well-suited for coastal installations and agrivoltaic (agricultural solar) projects. Additional certifications such as hail impact resistance and PID resistance further enhance their durability in challenging environments.
    Q What warranties are included with the 600–620W solar panels?
    All panels in this range come with a 12-year product warranty providing full manufacturer coverage against defects, and a 25-year linear power output warranty guaranteeing at least 84.8% of rated power at year 25. First-year degradation is capped at ≤2%, with an annual degradation rate of ≤0.55% thereafter.
    Q Which inverter brands are compatible with these high-power panels?
    Our 600–620W panels are compatible with all major utility-scale inverter brands including Sungrow, Growatt, Huawei, SMA, Deye, SAJ, Power Electronics, Ingeteam, ABB, and others. Our technical team can provide compatibility documentation and string design support for your specific project requirements.
    Q How do I get pricing and availability for 600–620W solar panels?
    As authorized distributors of Tier-1 manufacturers, we offer competitive pricing with full traceability and original factory warranties. Pricing varies by brand, model, quantity, and delivery location. Please contact our sales team directly with your project specifications to receive a current quotation and lead time information.
