Why Choose SGM: Unstoppable in the Sun
N-type cells sustain strong output in extreme heat—up to 10 W less power loss; temperature coefficient −0.29%/°C (≈0.29% output drop per +1 °C).
Cell options: TOPCon / BC (back-contact)
N-type designs available on request; cell efficiency up to 25% (subject to actual cell bin/spec).
Snow load: 5400 Pa mechanical test
≈ 550 kg/m², which can correspond to ~1.5 m of snow* under reasonable assumptions—maintains structural integrity in heavy winter conditions.
Wind load: 2400 Pa mechanical test
≈ 50 psf; when mounted per the installation guide, the array remains secure in high-wind sites.

FAQ
What are the lead time and MOQ?
Samples ship in ≤ 15 days; mass production in ≤ 30–45 days after PO/DP and drawing confirmation. MOQ depends on BOM/process (cell type, glass, frame color, cable spec). Expedites may be possible for repeat builds.
Are the panels compatible with 12/24/48 V systems?
A: Yes—12/24/48 V friendly. We provide wiring diagrams, string sizing guidance, and recommended MPPT input ranges to fit your inverter/charger.
Do you offer pre-drilled mounting and install docs?
A: Yes. Pre-drilled options available; hole maps (DXF/PDF) and torque specs provided for faster installs. Custom hole patterns and bracket kits are available on request.
What about warranty and the RMA process?
A: 10-year product warranty. A clear, documented RMA flow (with troubleshooting checklist, photo guide, and return steps) is included in the downloadable pack.
Which logistics and documents are supported?
A:DoC/CE/Certificate of Origin available; packing list & commercial invoice standard. DDP/FOB supported; NDA on request. HS codes and palletization specs provided.
How do SGM panels perform under partial shading (trees, snow, debris)?
SGM uses cell-level shadow-management (segmented strings + robust bypassing) to stabilize power and reduce hot-spot risk when partially shaded
What mechanical load ratings do you support?
Up to 5400 Pa snow and 2400 Pa wind (series/size dependent). Frame thickness and glass options can be tuned to your site loads.
Which cell technologies and power classes are available?
 Customizable with TOPCon or BC cells by project; power class and module geometry can be tailored to target voltage and footprint.
Can you do OEM/white-label?
Yes—custom label, frame/backsheet color, carton artwork, and barcode/UPC. Serial-number tracking and per-pallet QR manifests available.
What cables and connectors are standard?
MC4-compatible connectors with project-specific cable length and gauge options. Junction boxes are outdoor-rated; rear/side exit upon request.
What environmental and safety info do you provide?
Operating/use guidance, torque and bonding notes, hot-spot and shading notes, and electrical safety cautions are included in the install sheet.
How do you handle quality control and traceability?
Each batch ships with a spec sheet and batch trace info; inspection records can be appended for project deliveries if required by contract.
