📦 How to Source Solar Panels From China: A 2026 Buyer’s Guide

By our QC team · 12 min read · Updated April 12, 2026

China still manufactures about 80% of the world’s photovoltaic modules. But not all factories are equal, and not all 550 W mono panels are the same. This guide walks through what to check before you wire a deposit.

1. Decide your wattage tier

For 2026, the mainstream residential + small-commercial market is in the 410 W – 550 W range. Larger utility-scale projects use 580 W–720 W modules, often bifacial. Match your inverter’s MPPT range to the panel’s Voc and Isc before agreeing on a panel spec.

2. Verify certifications

The legitimate baselines are: IEC 61215 (design qualification) and IEC 61730 (safety). For specific markets you’ll also want:

• EU: CE, EN IEC certifications.
• US: UL 61730, UL 61215.
• Australia: CEC listing, AS/NZS 5033 compliance.
• China: CGC (for projects selling back to the grid).

3. Inspect the factory

A real PV factory has: lamination rooms (≥ 100 m²), IV testers, EL testers, automatic framing equipment. A “factory” with only an office and a warehouse is a trading company. Either is fine for buyers, but you should know which you’re dealing with.

🚢 EU vs. US vs. AU — Importing Solar: A Customs Guide

By our trade ops team · 9 min read · March 28, 2026

Importing solar panels from China isn’t just about shipping. Different markets have very different rules. This article compares the EU, US and Australian import pathways.

Common items across all three markets

• HS code: 8541.43 (photovoltaic cells assembled in modules).
• Certificate of Origin: required for tariff preference.
• Commercial invoice + packing list: must match lading.
• Bill of Lading / Air Waybill: title document.

EU-specific

CBAM (Carbon Border Adjustment Mechanism) reporting obligations started 2026 for solar imports. You’ll need a third-party-verified emission declaration. Anti-dumping duties on Chinese panels vary by factory.

US-specific

Section 201 tariffs apply to imported panels. UFLPA (Uyghur Forced Labor Prevention Act) means supply chain documentation is increasingly important — expect additional Customs & Border Protection scrutiny on polysilicon origin.

Australia-specific

Cleanest of the three markets for importers. CEC listing required for grid-tie. Standard customs duties are 5% on PV modules (0% on inverters in most cases).

⚡ String vs. Micro vs. Hybrid Inverters

7 min read · March 9, 2026

The most common inverter confusion we hear from new buyers: “I just need a 5 kW inverter, which one?”

The honest answer is: it depends on your roof, your shade profile, your battery plans, and your monitoring preferences. Here’s the cheat sheet.

• String inverters — the workhorse. Best when all panels get similar sunlight. Cheapest per kW. Single point of failure if it goes down.
• Micro-inverters — one per panel. Best for shaded or complex roofs. Higher upfront cost, longer warranty (often 25 years).
• Hybrid inverters — solar + battery in one box. Required if you plan to add batteries later.
• Off-grid inverters — for systems without grid connection. Higher surge capacity for motor starts.

For most residential and small-commercial buyers in 2026, a 5–10 kW string or hybrid inverter is the default. Spec out: MPPT count, peak efficiency, surge capacity, AC/DC coupling, and warranty terms.
