Products & Technical

Sizing is based on sun-hours, autonomy days, mounting height, and operating profile — not wattage labels. We use detailed solar irradiance data and usage patterns to design optimal systems for each location.

Yes, when correctly configured. Panel, battery, and controller logic are matched for sustained operation. We design systems with adequate autonomy days (typically 3-5 days) to handle extended periods of low sunlight.
Warranty terms depend on product category and configuration. LED fixtures typically carry 5-year warranties, while premium solar systems with LiFePO4 batteries can have up to 10-year warranties. All warranties are defined by real operating conditions.
Yes. Once approved, core components are locked to ensure batch consistency. This is especially important for large-scale infrastructure projects requiring uniform performance across all installations.
Yes. Datasheets, installation guides, wiring diagrams, and project documentation are available for all products. We also provide customized documentation for OEM partners.
Our products carry CB, CE, RoHS, and IP66 certifications. Specific products may have additional certifications based on target markets, including TUV, SAA, and UL listings.

Ordering & Support

Project location, application type, quantity, mounting height, and expected operating hours. Additional details like local solar irradiance data and autonomy requirements help us provide more precise configurations.
Most inquiries are reviewed and responded to within one business day. Complex project configurations may require 2-3 business days for detailed technical proposals.
Yes. Branding, packaging, and documentation customization are supported. Minimum order quantities apply for OEM orders, and we can discuss specific requirements during the quotation process.
Sample availability depends on the model and configuration. Standard products are typically available for sampling, while custom configurations may require a small pre-production run.
Our team reviews your requirements and proposes a recommended system configuration. We then discuss technical details, finalize specifications, and provide commercial terms including pricing, lead time, and shipping options.
We typically work with T/T (telegraphic transfer) with 30% deposit and 70% before shipment. For established partners, we may offer flexible payment terms. Letters of Credit (L/C) are also accepted for larger orders.

Shipping & Logistics

Standard products have a 15-25 day lead time depending on quantity. Custom configurations or OEM orders may require 30-45 days. We provide detailed production schedules upon order confirmation.
We work with major freight forwarders and can ship via sea, air, or express courier depending on urgency and volume. FOB Shenzhen and CIF to destination port are our standard terms.
We provide comprehensive installation guides and video tutorials. For large projects, we can arrange on-site technical support or training for local installation teams.
