The moment your deposit leaves your account, the questions start. Did the money reach the right company? Will the goods match the quotation? And if something goes wrong, is there any realistic way to get the money back? For most overseas buyers, payment is the single most stressful part of sourcing solar equipment from China — more stressful than technical specs, more stressful than shipping, because it is the one step where a mistake is instant and irreversible.
This guide is the payment companion to our factory verification guide. That article shows you how to prove the company you are dealing with is real before any money moves. This one assumes you have found a supplier worth paying and answers the next question: which China solar supplier payment terms keep a genuine dispute from turning into a total loss? We will walk through the six ways solar buyers actually lose money, rank the payment methods from safest to reckless, harden the industry-standard 30/70 wire formula, and list the contract clauses that make the difference when things go wrong. By the end, you will be able to protect a USD 5,000 trial order and a USD 200,000 project with the same logic.
The Six Ways Solar Buyers Actually Lose Money
Payment fraud in solar sourcing is rarely exotic. It is almost always one of six patterns, and once you can name them, most of them stop working on you.
1. The fake factory deposit
A company with a polished website, factory-style part numbers and convincing certificates quotes you a sharp price and asks for a 30% deposit. The deposit arrives; the company disappears, or turns out to be a one-room trading office with no ability to ship anything. This is the pattern our verification guide was written to stop — run the free checks and a video audit before the first wire, and this scam cannot reach you.
2. The bank account switch
This is the most expensive one because it hits buyers who did everything else right. You pay a 30% deposit to the correct corporate account. Weeks later, during production, the supplier’s email account is compromised and an invoice arrives: “our bank has changed, please wire the balance to this new account.” The new account belongs to the fraudsters. The money is gone within hours of arriving, and the real factory never received it — which means you may still owe the balance to get your goods. The defense costs nothing and is explained in the contract section below: the beneficiary account is written into the contract, and any change requires voice verification plus a company-stamped letter, with no exceptions.
3. The too-cheap quote with full prepayment
A quote lands 20–30% below every other offer you have received, but with one condition: 100% payment upfront to “lock the material price.” Real factories rarely need full prepayment for standard products, and nobody genuinely 20% cheaper stays in business for long. The combination of an extreme price and full prepayment is not a discount — it is the product being sold. Your deposit is the profit.
4. The quality bait-and-switch
Here the goods do ship, but not what you paid for: A-grade cells become B-grade, the promised brand-brand cells are replaced with unbranded ones, the inverter ships without the certifications your market requires. Specifying the exact certificate set for your destination market up front — see our CE vs UL vs IEC guide — is the cleanest way to make that substitution visible before the balance payment. This one is not theft in the criminal sense — which is exactly why it survives. The only defenses are a specification sheet signed as part of the contract, and a pre-shipment inspection before the balance payment. Both are covered below.
5. Payment to personal accounts
Any request to send money to a personal bank account, a WeChat wallet, Alipay, Western Union, or cryptocurrency is a stop sign, no matter how good the story is (“the company account is under maintenance,” “it saves the tax,” “it is the boss’s account”). Business-to-business payments in China go to corporate accounts in the company’s registered name. There are no legitimate exceptions, and a supplier who insists on one has told you everything you need to know.
6. The expediting fee
Production finishes, then a new message: goods are ready, but releasing them now requires an “expediting fee,” a “customs clearance fee,” or a “document fee” paid first — often to a different account. Legitimate suppliers price the full cost in the proforma invoice. Unexpected pre-shipment fees demanded outside the contract are a renegotiation attempt at best and fraud at worst; the correct response is to refer to the signed PI and hold your position.
Payment Methods, Ranked From Safest to Reckless
No payment method is “safe” by itself. Safety comes from matching the method to the order size and adding the right conditions. Here is the honest ranking for solar equipment:
| Method | Best for | Money at risk before shipment | Cost and friction | Verdict |
|---|---|---|---|---|
| T/T wire 30/70 | The industry default for orders up to ~USD 100k | 30% deposit | None beyond bank fees | Safe when hardened (see below) |
| L/C at sight | Project orders above ~USD 100k | Near zero pre-shipment | 0.5–1.5% bank fees, strict documents | Best protection for large orders |
| Alibaba Trade Assurance | First trial orders under ~USD 20k | Covered by platform rules | Built into platform pricing | Good for first contact with a new supplier |
| T/T 100% upfront | Small accessory orders only | 100% | None | Avoid for any real equipment |
| D/P or D/A | Rare in solar | High | Bank collection | Avoid — weak protection |
| Western Union / personal account / crypto | Nothing | 100% | — | Walk away, always |
Two notes on the table. First, the L/C threshold is not a rule — it is economics: opening, amending and negotiating a letter of credit costs real money and requires clean, complete shipping documents, which is why it earns its keep on large project orders like a commercial and industrial ESS project rather than on single pallets. Second, Trade Assurance protects the transaction you file through the platform only. A supplier who steers you off-platform after first contact on Alibaba is removing your protection, and that should reset the conversation.
The T/T 30/70 formula, hardened
A plain 30/70 wire — 30% deposit, 70% before shipment — is the industry default, and it is exactly what an unprotected buyer gets. Hardening it changes the conditions attached to each payment, not the percentages:
| Stage | Typical share | Condition before you pay |
|---|---|---|
| Deposit | 20–30% | Signed contract and PI naming the beneficiary account; video audit or verification checks completed |
| Mid-payment (large orders only) | 20–30% | Production photos and, for project orders, a third-party mid-production inspection |
| Balance | 40–60% | Pre-shipment inspection report received and accepted; copy of the bill of lading reviewed |
The single most important line is the last one: never pay the balance against photos alone. A pre-shipment inspection by SGS, Bureau Veritas, TUV or an independent inspector costs roughly USD 300 and checks quantity, workmanship, packaging, labeling and — if you ask — the exact model numbers against your specification sheet. On any order above a few thousand dollars, that USD 300 is the cheapest insurance you will ever buy, and the inspection happens while you still hold 100% of the leverage: the balance.
Contract Clauses That Actually Protect Your Money
Most disputes are decided by five to seven lines of text that cost nothing to include. Insist on these in every solar purchase contract or proforma invoice:
- Beneficiary account clause. The contract states the exact corporate beneficiary account. Any change of account requires a company-stamped letter on official letterhead and voice confirmation via a phone number you already had on file — not one provided in the change-request email. This single clause kills scam #2.
- Specification annex. The exact models, cell type and tier, capacities, certifications and brands are listed in an annex and referenced as an integral part of the contract. For batteries, mirror the parameters in our LiFePO4 battery selection guide — cycle life, BMS limits, cell grade — because “same as sample” protects no one.
- Warranty in writing. Warranty years, what triggers them, and who pays freight on a replacement. A supplier confident in its product states it plainly — for example, we write warranty terms such as 5 years on liquid-cooled ESS and 10 years on C&I batteries directly into the contract.
- Inspection right. The buyer (or a named third party) may inspect goods before shipment, and the balance payment is due only after the inspection report is accepted.
- Delay remedy. A defined remedy if shipment slips beyond an agreed window — typically a penalty percentage or the right to cancel the unpaid portion. It does not need to be harsh; it needs to exist.
- Full legal names. The contract names the company exactly as registered (for us: Hefei Henghui New Energy Co., Ltd) and the account name must match it. If the account name and the contract name ever differ, stop paying and ask why.
A Worked Example: Paying for a USD 45,000 Inverter + Battery Order
Here is how the pieces fit together on a realistic mid-size order — a container of hybrid inverters and stacked batteries for a distributor, quoted at USD 45,000:
| When | What happens | Money moves? |
|---|---|---|
| Day 0 | Contract and specification annex signed; beneficiary account name checked against the bank record; video audit completed | 30% deposit — USD 13,500 |
| Week 1 | Production starts; live video check-in on the line | No |
| Week 4 | Goods finished; third-party pre-shipment inspection (~USD 310) verifies quantity, exact model numbers, firmware and language settings, labeling, packaging and a carton drop test | No |
| Week 4 | Inspection report accepted; scan of the bill of lading reviewed | 70% balance — USD 31,500 |
| Week 5 | Container sails; original documents released per the contract | No |
Total protection cost: USD 310 plus one evening of verification before Day 0. Total exposure at the moment of maximum risk — the balance payment — effectively zero, because the inspection happened while you still held the money. This is not a sophisticated scheme. It is the plain 30/70 default with three cheap additions, and it is available to any buyer of any size.
The 60-Second Red Flag Checklist
Run any new supplier — and any mid-order surprise — against this list. One flag means ask questions. Two or more means pause the payment until they are resolved:
- The quote is 20%+ below every other quote you received
- Payment is requested to a personal bank account, WeChat, Alipay, Western Union or crypto
- The bank account name does not exactly match the company name on the contract
- A mid-order email asks you to switch the beneficiary account (verify by phone using a number you had before the email — never a number from that email)
- The supplier refuses a video factory tour or third-party inspection
- Certificates (CE / IEC / UL) cannot be provided for the exact model quoted
- Pressure to pay 100% upfront “to lock the price”
- No contract, or a contract without a specification annex
- New fees appear after production is finished
- Communication runs only on WhatsApp with a free email address on the quotation
If you have not yet verified the company itself, start with our factory verification guide before worrying about payment structure — the two work as a pair, and verification is always first. Our earlier supplier selection guide covers the shortlisting stage that comes before both. Once you are comparing quotes, our guide to FOB vs CIF vs DDP shows how to rank them on landed cost rather than unit price.
How We Structure Payments at EverRay
We are a solution provider managing a network of more than 20 audited partner factories — solar modules, hybrid inverters, batteries and complete energy storage systems — rather than a single-line factory, and that shapes how our payments work. The practical effect for you: one contract with one legal entity, Hefei Henghui New Energy Co., Ltd, covers a complete system — modules, hybrid inverters, batteries and a commercial ESS — so you are not wiring deposits to five different factories for one project and hoping the pieces arrive together.
Our standing payment terms are simple and auditable:
- All payments go to the corporate account of Hefei Henghui New Energy Co., Ltd, named in the contract — never to any personal or third-party account
- Standard structure is 30% deposit and 70% balance against a pre-shipment inspection report and shipping document copies; L/C at sight is accepted on project orders
- Third-party inspections (SGS, Bureau Veritas, TUV or your own inspector) are welcome, and we schedule factory access for them directly
- Video audits of partner factories and live production lines are a standing offer — bring the script from our verification guide
- Certificates — CE, IEC, UL and UL9540 — are provided per exact model, and warranty terms (5 years on liquid-cooled ESS, 10 years on C&I batteries) are written into the contract
The logic is the same one running through this whole article: a supplier who is confident about what is behind the quotation has no reason to fear verification, inspection or a hardened payment structure. Our largest reference project to date is a 500 MW / 1 GWh deployment in Colombia, structured with exactly these protections. More about how we work is on the about page.
Frequently Asked Questions
Is T/T 30/70 safe for a first order from China?
A plain 30/70 wire to a verified company is industry-normal, but “hardened” 30/70 is meaningfully safer: sign a contract with the beneficiary-account and specification clauses, verify the company first (video audit at minimum), and attach the balance payment to a pre-shipment inspection report. With those three additions, the maximum you can lose on a first order is the deposit — and with a real factory, that risk is small.
What deposit percentage is normal for solar equipment?
20–30% deposit with the balance before shipment is standard across modules, inverters and batteries. Requests for 100% prepayment on production equipment are a red flag regardless of the discount offered. The exception is small accessories and samples, where full prepayment of a few hundred dollars is normal.
Should I open a letter of credit for one container of panels?
Usually not. Bank fees and document workload make an L/C worthwhile roughly above the USD 100k mark or on strict-market project orders. Below that, a hardened T/T plus pre-shipment inspection gives you nearly all of the protection at a fraction of the cost. For very small first orders, Trade Assurance is the pragmatic middle ground.
The supplier emailed new bank details mid-order. What do I do?
Treat it as fraud until proven otherwise. Do not reply to the email. Call the supplier on the phone number you had on file from before the order — not any number in the new email — and require a company-stamped change letter. Legitimate banks and companies do not change beneficiary accounts by email alone. This pattern, the account-switch scam, is the most expensive fraud in cross-border trade precisely because it arrives when you are relaxed: mid-order, on schedule, expecting the balance invoice.
I already wired money to a scammer. Can I get it back?
Act within 48–72 hours: ask your bank to request a SWIFT payment recall, file a report with your local police, and if the transaction touched a platform like Alibaba, file there immediately. Recovery rates are low — which is the entire argument for spending an evening on verification and a few hundred dollars on inspection instead. Prevention is the only reliable refund policy in cross-border trade.
