FAQ
What factors influence the final 660 watt solar panel price for a project?
The final cost is influenced by order volume, incoterms (FOB, CIF, etc.), current raw material market prices, and specific certification requirements. We provide transparent, volume-based quotations tailored to your project's scale and delivery needs.
Are these panels compatible with existing string inverters?
Yes. The voltage and current parameters of our 660W panels are designed to work seamlessly with most major 1500V string inverters available on the market. Our technical team can provide detailed compatibility sheets upon request.
What is the typical lead time for a 1MW order?
For standard orders, lead times typically range from 4-6 weeks. We maintain strategic inventory and offer flexible production scheduling to accommodate urgent project timelines.
Do you provide full technical documentation and certifications?
Absolutely. Our panels come with complete documentation, including datasheets, IEC/UL certificates (TÜV, CE, etc.), warranty statements, and a comprehensive installation manual. All certifications are available for client review.
How does the higher wattage affect balance-of-system (BOS) cost savings?
Using 660W panels instead of lower-wattage modules can reduce the number of panels by ~15-20% for the same system size. This directly reduces costs for racking, connectors, cabling, and installation labor, contributing to a lower overall installed cost per watt.
