Frequently Asked Questions
What are the main advantages of shingled solar panels?
Shingled solar panels eliminate the traditional cell gaps and busbars, which increases the active area for sunlight absorption. This leads to higher efficiency (up to 23%), better performance in shade, and improved mechanical durability against micro-cracks.
How do you ensure the quality of each solar module?
We implement a rigorous 4-step EL (Electroluminescence) inspection process covering every stage from individual cells to the final laminated module. This ensures zero defects, such as hidden cracks or inactive areas, before shipment.
Are these solar panels certified for international use?
Yes, our solar panels are fully certified by leading international bodies including TUV, SGS, CQC, and ISO, ensuring they meet global safety and performance standards.
What is the typical lead time for a bulk order?
For a standard container order, the typical delivery time is approximately 10 working days after the receipt of payment, ensuring a fast turnaround for your projects.
Do you offer flexible payment options?
We offer various payment terms including TT (with advance and balance options), L/C for larger orders exceeding 50,000 USD, and Western Union for smaller sample orders under 5,000 USD.
Why choose shingled technology over traditional busbar panels?
Shingled technology reduces energy loss caused by ribbon shading and provides better temperature coefficients. The layout also allows for more cells to be packed into the same footprint, maximizing your power density.
