Q: What is the normal minimum order quantity for custom solar panels?
Most factories require 500-1,000 units for custom specs. There is a minimum of 50 pieces of Singold for non-standard sizes, voltages and designs. This makes custom panels accessible to small retailers, regional distributors, and project developers who don’t need – or can’t commit to – containerload quantities.
Q: Do custom solar panels with low MOQ come with real certification?
They should. At Singold, every panel ships with valid IEC 61215, IEC 61730, CE, TÜV, or UL documentation — regardless of order size. Our modular design platform uses pre-verified electrical architectures, so most custom physical variations do not require full verification. Ask any manufacturer for a test report matching your exact custom specifications. If they can’t provide it, that’s a problem.
Q: How long does it take to deliver custom panels?
Project 15-25 working days from order confirmation: design sign-off takes 2-3 days, sample approval takes 5-7 days, production and QC takes 10-15 days. We keep common materials in stock to avoid raw material delays that take less manufacturing factories up to 45-60 days lead time. Re-orders on existing designs are shipped in 15-18 days.
