No. Our products are specially optimized for different climates:​

• High – temperature and high – humidity areas: Modules adopt anti – PID (Potential Induced Degradation) technology; inverters have high – temperature overload protection.​

• Low – temperature and cold areas: Modules have good low – temperature resistance; inverters can start normally at -25℃.​

• Rainy and snowy areas: Modules have high waterproof grade (IP67/IP68); the surface coating is anti – snow and easy to clean.

Yes. We offer tailored solutions for household, commercial, industrial, and special scenarios (e.g., marine, remote areas). Customizations include:​

• System size/power matching your energy needs;​

• Space – adaptive designs (e.g., limited roof space, no structural modifications);​

• Climate/usage – specific optimizations (e.g., anti – salt 雾 for coastal areas, tracking brackets for low – light environments);​

• Integration with energy storage or smart management systems. Contact our sales team to share your requirements for a personalized plan.

• Small orders (household products): 3 – 7 working days (in – stock items); 15 – 20 working days (customized items).​

• Bulk orders (commercial/industrial products): 25 – 40 working days, depending on the order quantity and production schedule.

Basic maintenance is required:​

• PV modules: Clean the surface 2 – 4 times a year (avoid scratching with hard objects);​

• Inverters: Check the connection status every 6 months;​

• Energy storage batteries: Avoid overcharging or over – discharging; charge at least once every 3 months when not in use.
