Frequently Asked Questions
QWhat is the difference between N-type and P-type solar panels in the 600–620W range?
N-type panels (such as TOPCon or HJT technology) generally offer higher efficiency, lower temperature coefficients, and better low-light performance compared to P-type PERC panels. N-type modules also tend to have lower first-year degradation. Our 600–620W portfolio includes both options depending on brand and model, allowing you to select based on your project's performance and budget requirements.
QAre these 600–620W panels suitable for residential rooftop installations?
Due to their large physical dimensions (typically over 2.3m in length) and high wattage, 600–620W G12 panels are primarily designed for utility-scale and large commercial ground-mount projects. For residential or small commercial rooftop applications, we recommend considering smaller-format modules. Please contact our team for guidance on the most suitable panel size for your specific project.
QWhat does bifacial capability mean, and how much extra energy can it generate?
Bifacial solar panels can absorb sunlight from both the front and rear surfaces. The rear side captures reflected (albedo) light from the ground or surrounding surfaces, providing an additional energy yield typically ranging from 5% to 30% depending on ground reflectivity, installation height, and tilt angle. Ground-mount installations with light-colored or reflective surfaces benefit the most from bifacial technology.
QWhat certifications do your 600–620W solar panels carry?
All panels in our 600–620W range are sourced from Tier-1 manufacturers and carry internationally recognized certifications including IEC 61215, IEC 61730, and UL 61730 where applicable. Additional certifications such as MCS, CE, TÜV, and regional grid-connection approvals are available depending on the brand and destination market. Full certification documentation is provided upon request.
QHow does the 25-year linear power warranty work?
The 25-year linear power warranty guarantees that the module's power output will not fall below a specified percentage of its rated power at any point during the warranty period — typically 98% after year 1, then declining linearly by no more than 0.55% per year, reaching a minimum of 84.8% at year 25. This warranty is backed directly by the original manufacturer and is transferable with the installation.
QCan I mix 600–620W panels from different brands in the same solar array?
While it is technically possible, mixing panels from different brands or models in the same string is generally not recommended, as differences in electrical characteristics (Vmp, Imp, temperature coefficients) can lead to mismatch losses and reduced overall system performance. If multiple brands are required for a large project, we recommend assigning each brand to separate strings or inverter inputs and consulting our technical team for system design support.
