Common Specifications (All Models)
Frequently Asked Questions
Can you customise dimensions, frame colour, and junction box?
Yes. Frame is standard anodised aluminium in silver or black; dimensions can be tuned to your mounting rails; junction box is IP67 with MC4-compatible connectors standard, but other connector types are available on request; output cable length is 50 cm by default and can be extended to any length.
What is the minimum order quantity (MOQ)?
Sample orders and custom prototype orders start at 50 pcs. Full-container orders are priced per spec and container load depends on module dimensions (smaller modules fit more per 40HQ).
What cell technology do these small modules use?
Main lineup is N-type TOPCon half-cut 182mm cells — the same cells we use in our 620-640W utility modules. HJT is available for hot-climate applications. PERC has been phased out across our catalog.
Are they certified for EU / US markets?
Yes — the small-module line carries IEC 61215, IEC 61730, TÜV NORD, CE, RoHS, ISO 9001 / 14001 / 45001, Intertek and UL marks, matching the certification stack on our utility modules.
How long is the lead time?
30–45 days FOB Ningbo for custom-spec orders. Standard SKU pull-out from inventory is faster when stock is available — ask Frank when you submit a spec inquiry.
Why choose JUST SOLAR for small modules vs a dedicated off-grid brand?
Dedicated off-grid brands often cut corners on cell grade and lamination because the projects are small and hard to audit. JUST runs small modules on the same AAA-grade cell line + same lamination line as our bankable 620-640W utility modules — you get utility-grade quality at small scale, with full global certifications. For any project that needs to pass inspection, finance review, or outlast 10 years in the field, this matters.
