Frequently Asked Questions (FAQ)
What is the typical price range for a 40W solar panel?
The 40w solar panel price varies based on cell technology (mono vs. poly), brand, certifications, and order volume. As a direct manufacturer, we provide tiered wholesale pricing that becomes significantly advantageous for container-load (FCL) orders, offering the best value for large-scale procurement.
Can this panel be used to charge a 12V battery directly?
While the voltage is suitable for a 12V system, we strongly recommend using a solar charge controller between the panel and the battery. A PWM or MPPT controller regulates the charging process, preventing overcharging and deep discharge, which critically extends battery life.
What is the lead time for a 20-foot container order?
For standard 40W panel orders, the lead time is typically 15-20 days after deposit confirmation. We provide real-time production updates and shipping documents. Custom OEM orders may require additional time for setup.
Do you provide technical datasheets and warranty documents?
Yes. Comprehensive technical datasheets, IEC certification copies, and formal warranty documents are provided with every shipment. These are essential for your project documentation, customs clearance, and end-customer assurance.
How should these panels be stored before installation?
Store in a cool, dry, and well-ventilated area away from direct sunlight if possible. Keep them in their original packaging, laid flat, and avoid placing heavy objects on top. Prolonged storage (over 6 months) should be done with the terminals covered and under controlled conditions.
