FAQ
Q: When should I choose monofacial over bifacial panels?
A: Monofacial panels are typically the superior choice for projects with budget constraints, installations on dark or non-reflective surfaces (like standard gravel or grass), or in high-density layouts where rear-side illumination is limited. The decision in the monofacial vs bifacial solar panels debate hinges on specific site conditions and financial models.
Q: What is the expected annual degradation rate?
A: Our panels feature a very low degradation rate. The first-year degradation is ≤2%, followed by a linear annual degradation of ≤0.45%, ensuring over 87.4% of nominal power output at the end of the 30-year warranty period.
Q: Do you offer custom specifications for large-volume projects?
A: Yes. For utility-scale and large commercial tenders, we offer flexible customization options for power class, frame color, junction box type, and cable length. Contact our sales team with your project requirements.
Q: How do I determine if my site is better for monofacial or bifacial?
A: A key factor is ground albedo (reflectivity). Sites with highly reflective surfaces (e.g., white gravel, sand, concrete, or snow) may benefit more from bifacial gains. For standard terrain, a monofacial system often provides the most straightforward and economical solution. Our technical team can assist with a site-specific yield analysis.
Q: What are the standard packaging and shipping terms?
A: Panels are securely packed in palletized wooden crates. Standard containers (20'GP, 40'GP, 40'HQ) can be accommodated. We offer flexible trade terms (EXW, FOB, CIF, DAP) based on your needs and destination.
