Our First Outpost in Changzhou Had Just Two People
In May 2017 we rented an 800-square-meter warehouse in Changzhou's Xinbei district — under 100,000 yuan of total assets, two people. In one year they inspected 114,000 modules, shipped 68 containers, and rejected seven batches, including one of 900 modules with an 11% microcrack rate.
In March 2017, I put a proposal to the boss: set up a point in Changzhou.
The reasoning was plain. Seventy percent of our PV module suppliers are in southern Jiangsu — the Changzhou–Wuxi–Zhenjiang belt. Goods shipped from the factories to our Guangzhou warehouse, we inspected, and when we found problems we shipped them back — two weeks round trip, plus a fight over freight. Move inspection to the factory gate, and problem goods never get on the truck.
There was another reason I didn't say straight out: first-tier factories' goods never reach us, and the second-tier ones are scattered across townships all over southern Jiangsu. Unless you're based there, you don't even know which factory has stock this week.
Two people, one warehouse
Approved in April. In May I rented a small warehouse in Changzhou's Xinbei district — 800 square meters, 18,000 a month, three months' deposit plus one up front. I looked at three warehouses before deciding: the first, in Zhonglou district, was cheap but the roof leaked; the second didn't have the ceiling height for a forklift; the third was two kilometers from the expressway exit, and every supplier township was within forty minutes' drive.
Staffing was two people: Xiao Zhang, an inspector transferred from the Guangzhou warehouse, and me flying over for one week a month.
Opening day had no ceremony. Xiao Zhang bought two chairs and a desk, a used power test bench for 32,000, and an EL tester for 46,000. Total assets: under 100,000.
The day the bench arrived, we calibrated it three times against a module of known power; the readings were off by 0.8 watts — within tolerance. That used machine went on to test 110,000 modules without a single error.
The boss came for one look and said: just these two people? I said two is enough. This point holds no stock. It does three things: inspect, supervise loading, and retain samples.
What the two of them do
Xiao Zhang's routine went like this. A supplier reports a batch; he first checks the factory data, then goes on site for sampling. Three percent of every batch, power test plus EL, module by module. Passing modules get our blue label; failing batches go back whole — not one module accepted.
Loading supervision means watching the containers get packed. Modules fear knocks and pressure — how pallets sit, how gaps get stuffed, how doors get closed — he photographs the whole process, at least 120 photos per container.
Once a driver pushed to close the doors and catch the expressway. Xiao Zhang refused, insisting on stuffing the top row's gaps with foam strips. It cost twenty extra minutes. That container reached Kenya without a single broken module.
Sample retention: four modules sealed per batch, numbered and archived, kept six months. Only released if no dispute arises.
Xiao Zhang's daily schedule: arrive at nine, process inspection orders sent from Guangzhou; out by ten-thirty to run factories, two or three a day; afternoons inspecting and labeling; evenings back at the warehouse sending photos and reports to Guangzhou — same day, no exceptions.
I reviewed reports in Guangzhou. Any abnormal power data meant he re-tested the next day. In one year, eleven re-tests — eight found real problems.
What one year inspected
From June 2017 to May 2018, that two-person point inspected 114,000 modules and shipped 68 containers.
Whole batches rejected: seven. The most memorable was a September batch of 900 modules — beautiful on the outside, but under EL the microcrack rate was eleven percent. The supplier's boss said cracks you can't see don't matter. I said: in three years the power loss will be very visible. The whole batch went back.
The sample rack stood in the back of the warehouse — four tiers of steel shelving, modules standing upright, each with a numbered tag. If any container had a problem, give the container number and the retained sample's raw data was in hand in five minutes.
If that batch had gone to Africa — by the lesson of our first 80,000-yuan loss — it would have been another several-hundred-thousand-yuan hole.
Over that microcrack batch, the supplier's boss invited Xiao Zhang to dinner and proposed just labeling them through, with another two fen off the price. Xiao Zhang called me. I said: tell him to save the dinner money; the goods go back. That factory spent three months rectifying, and their next batches passed. They still supply us today.
Cost and value
I calculated the point's annual cost: rent 216,000, two people's wages and social insurance 190,000, equipment depreciation plus travel 60,000 — 466,000 total.
The boss asked if it was worth it. I gave him the other ledger: the step of sending goods to a third party after reaching Guangzhou was eliminated — 18,000 saved per container, 1.22 million across 68 containers. And that doesn't count the seven batches we stopped.
There's an invisible ledger too: problems used to surface only after goods reached Guangzhou, and sailing schedules collapsed. Now problems get solved at the factory gate. In the first half of 2018, not one of our shipments changed vessels over module issues.
Xiao Zhang out there alone paid a price too. His girlfriend was in Guangzhou. One year — they split. He asked once about transferring back; I didn't approve it, and gave him an 800-yuan raise instead. That I owe him. The Changzhou point owes him.
Last month the Changzhou point added a third person. The warehouse is still 800 square meters, not expanded. A point doesn't need size — it needs the factory gate. Forty minutes from the factory means problems happen at the factory, not at sea.
If you want to verify our modules, you don't need to come to Guangzhou. The retained-sample rack in the Changzhou warehouse has serial numbers. Give me the container number and I'll send you the sample's EL images. That works better than a hundred assurances from me.
