    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, lower light-induced degradation (LID), and better performance in high-temperature conditions compared to P-Type panels. P-Type panels remain cost-effective and widely proven in utility-scale projects. Both are available within our 600–620W portfolio depending on brand and model selection.
    Q Are 600–620W panels suitable for rooftop commercial installations or only utility-scale projects?
    While these large-format panels are optimized for utility-scale and large commercial ground-mount projects due to their size and weight, they can also be used in rooftop commercial installations where structural load capacity and roof space allow. Our technical team can help assess suitability for your specific project.
    Q What does the 25-year linear power warranty cover?
    The 25-year linear power warranty guarantees that the module will produce at least 84.8% of its rated power output by year 25, with a first-year degradation of no more than 2% and an annual degradation rate of no more than 0.55% thereafter. This warranty is backed by the original Tier-1 manufacturer and is transferable with the project.
    Q Can these panels be integrated with single-axis solar trackers?
    Yes. Our 600–620W panels are compatible with leading single-axis tracking systems including Array Technologies, Nextracker, Soltec, PV Hardware, TrinaTracker, and Arctech Solar. Tracker compatibility depends on module dimensions and wind load ratings, which our technical team can confirm for your chosen brand and model.
    Q How does bifacial technology increase energy yield in the 600–620W panels?
    Bifacial panels capture sunlight on both the front and rear surfaces. The rear side generates additional energy from reflected light (albedo) off the ground or surface beneath the array. Depending on ground reflectivity and installation design, bifacial gain can add 5–15% additional energy yield compared to monofacial panels of the same rated power.
    Q What documentation is provided with each order of 600–620W solar panels?
    As authorized distributors, we provide complete technical documentation including product datasheets, IEC and UL certification reports, EL testing records, packing lists, and original manufacturer warranty certificates. Full traceability documentation is available to support project financing, grid connection approvals, and insurance requirements.
