Q1: What are the main benefits of shingled solar panel technology?
A: Shingled technology eliminates the cell gaps found in traditional panels, increasing overall mono-facial module efficiency to between 22% and 23%. It also provides stronger resistance to cracking, resulting in significantly lower micro-crack power loss.
Q2: How is the quality of the solar cells verified?
A: We use A-grade solar cells from top PV industry brands like Ongwei or Huansheng. The quality is secured via a strict inspection process that includes 100% inspection of raw cell materials for power and color consistency, along with four separate EL inspections during key assembly and lamination phases.
Q3: What certifications do these flexible solar modules have?
A: These transparent, flexible CIGS solar panels and module products are officially certified and approved by leading bodies including TUV, CQC, BE, SGS, and ISO.
Q4: What are the available payment terms for orders?
A: For standard orders, we accept TT (30% in advance and balance before shipment for EXW/FOB, or against the copy of B/L for CFR/CIF). For orders above 50,000 USD, we accept L/C at sight, and for small transactions under 5,000 USD, Western Union can be utilized.
Q5: How long does delivery take for a full container of solar panels?
A: The standard delivery timeframe is 10 working days from the receipt of payment for a single container.
Q6: What temperature ranges can these CIGS flexible modules withstand?
A: These modules are built for durability and are certified to operate reliably in harsh environments with temperature ranges from -40°C up to 85°C.
