Small Solar Modules
40W to 320W. 31 wattage variants.

1 × 40HQ container per wattage. Typical container holds ~1,000-3,000 pieces depending on wattage (e.g., 80pcs/pallet × 20 pallets for 40W; fewer for 200W+). For mixed-wattage orders serving a specific application (e.g., streetlight kits with 60W + 80W + 120W): negotiable down to 50% container allocation with longer lead times. For first-time buyer trial orders: please ask about sample quantities (fees apply).

No — small modules have a 10-year product + 10-year performance warranty, appropriate for the small-module segment. The reason: small modules (especially solar light, streetlight, RV) typically face harsher deployment conditions (physical handling, bump/shock, exposed installations) than stationary utility modules. The 10-year warranty matches industry standard for this segment. For applications requiring longer warranty (e.g., off-grid homes as long-term residential installations), we can offer extended warranty at premium.

Yes. OEM / private-label is standard for small modules — we ship modules under buyer brand names in 30+ countries. Customizations available: nameplate labeling, frame color, J-box branding, custom voltage configs, retail packaging, multi-language manuals, QR-coded barcodes. Minimum 1 container per SKU for label-only OEM; custom wattage or size requires 5+ container commitment. Timeline: 4-6 weeks from spec sign-off to first shipment.

Standard: 18V (for 12V battery systems), 24V (for 24V systems), 36V (for 36V systems or larger direct-DC applications). Open-circuit voltages: 18V panels ~22-24V Voc, 36V panels ~44-48V Voc. Custom voltages for specific battery chemistries (LiFePO4, AGM, Gel) or direct-DC applications available on request for 5+ container orders.

Yes. All JUSTSOLAR small modules are IEC 61215 + IEC 61730 certified under our factory certification scope. For CE, UL, or region-specific certifications (BIS India, INMETRO Brazil, etc.), availability varies by wattage — please confirm your target market's required certifications before ordering. We support the certification transfer process for distributors doing private-label arrangements.

Small modules are typically $0.05-0.15/W more expensive than utility modules on a $/W basis — because the manufacturing process has lower throughput (smaller production batches, more labor-intensive assembly) and customization. However, small modules are sold by PIECE, not $/W — and the margin per unit is much higher than utility modules. For distributors: small modules are often the more profitable segment because they serve retail and installer channels with less price pressure than bulk utility procurement.

Yes. Sample orders of 1-2 pieces per wattage are available for quality evaluation. Sample pricing is ~2-3× container pricing due to the small order overhead. Shipping via DHL/FedEx at your cost. Typical sample lead time: 3-5 days from payment. Sample fees credited against first full container order if placed within 90 days.
