Frequently Asked Questions (FAQs)

Can this 50W flexible solar panel support OEM & ODM customization? What is your MOQ?

We support full OEM & ODM services, including custom color boxes, brand logo silk printing, parameter labels and cable length. Our regular bulk MOQ is 50pcs, sample order is acceptable with 1pc for quality testing. We can negotiate a lower MOQ for large orders, and also provide customized solar charging kits as bundled packages.

What international certifications do you have? Can you offer certification documents and certificate of origin for customs clearance?

Our product is certified with CE, UL, FCC, RoHS, ISO9001, which meets customs standards for Europe, USA, Australia and Southeast Asia. We provide free certification copies, CO certificate, proforma invoice and packing list for customs declaration, and we can also apply for GSP certificate upon your request.

What is the actual power conversion efficiency? Can it work stably under low-light and saltwater marine environments?

Adopted Grade A monocrystalline cells with efficiency over 23.5%. It can keep more than 75% power output under weak light of 200W/㎡. The ETFE marine-grade surface with IP67 waterproof & dustproof rating resists UV and salt corrosion perfectly, ideal for long-term RV, yacht and marine applications without yellowing or cracking.

Which portable power stations is this panel compatible with? Can it charge 12V lead-acid & lithium batteries directly?

Equipped with standard MC4 connectors, it is fully compatible with EcoFlow, Jackery, Bluetti, GoLabs and most mainstream power stations. With 24V Vmp and 28.5V Voc, it is designed for 12V battery systems. It can safely trickle charge and maintain 12V lead-acid & lithium batteries with a matched solar charge controller.

What is the maximum bending range? What is the minimum static bending radius? Any installation tips?

The minimum static bending radius is ≥25cm, which allows seamless installation on curved RV roofs and boat decks. Do not fold sharply or bend repeatedly. We recommend installing with structural adhesive or buckles, avoid stepping on the panel or scratching the ETFE surface with sharp items.

What is your bulk order lead time? Which payment terms do you accept? Can you arrange door-to-door DDP shipping?

Lead time for stock orders is 3-7 working days, 15-25 days for OEM customized orders. We accept T/T, L/C and Alibaba Trade Assurance. We cooperate with professional freight forwarders to provide sea, air and express shipping solutions, DDP tax-included delivery service is available for most countries.

How long is the product warranty? What after-sales policy do you have for bulk quality issues?

How long is the product warranty? What after-sales policy do you have for bulk quality issues? A: We offer 5-year factory warranty with guaranteed power attenuation performance. Every panel passes 3 times power testing before shipment to avoid fake power rating and leakage. For bulk defective products caused by manufacturing problems, we support free reshipment, discount compensation or product replacement.

Can we connect multiple panels in series or parallel? How many panels can be connected at most? What accessories are needed?

The maximum system voltage is 600V DC, up to 20 pieces of this 50W panel can be connected in series. Parallel connection can boost charging current for large-capacity power stations. A matched solar charge controller and MC4 branch connectors are required for safe use. We also supply all supporting accessories for wholesale orders.
