A purlin cutting crew pockets a small sum for each century of pieces off the cold saw. Output climbs. So do short lengths and holes punched a few millimetres off centre. Nobody notices until an installation crew on a rooftop in another state finds that brackets will not line up. The rework costs more than a month of incentives, and the crew still believes it did a good job, because the scheme told it so.
Bonus schemes in module, steel and pack plants of this group usually began as a simple push for volume during a busy order. Over time they shape behaviour more than any rule. If the count happens at the bench, the bench learns to hurry. If it happens after a quality gate, the bench learns to care.
Where output-only schemes go wrong
- Mounting steel: pay per piece cut or punched, so length and hole position slip.
- Module lines: a daily framing or packing target, so cracked or poorly laminated modules are pushed through for EL to catch, or not.
- Junction box and connector benches: pay per crimp or per housing, so half-seated crimps and missing seals pass.
- Pack assembly: bonus per pack closed, so torque checks are skipped and insulated tools are left on the board.
- Wind parts: crew bonus on mould turnaround, so resin cure or bagging checks are rushed.
- Inspection: inspectors judged on how many parts they clear, which quietly asks them to look less closely.
Move the count to a quality gate
The simplest fix is to count output at a point after quality has been checked. For modules, that is EL imaging and flash test. For mounting steel, galvaniser acceptance or a tape-and-template check on pieces pulled from each bundle. For crimp and box lines, pull test and visual inspection. For packs, end-of-line test. For wind parts, the customer's or your own inspection hold point. People still earn for volume, but only for volume that passes.
A second option is a quality multiplier. The full payout holds while the line's right-first-time count stays above an agreed mark, and steps down beneath it. This works where defects point back to a line or crew but not to a person. Keep the steps few and the levels visible on the shift board.
Design rules that keep a scheme trusted
- 1
One output measure, one quality gate, one safety condition
For example: good modules passed at EL per shift, paid only if the line's breakage stays below an agreed level, and forfeited for that shift if a safety non-negotiable is broken.
- 2
Team or individual, decide deliberately
Where a defect has one author, such as a welder's bead, individual counts can work. Where they trace to a line, such as a stringer and lay-up sequence, pay the crew together.

Publish it on one page
What is counted, where, who counts it, what is paid and when. In the local language. Posted on the shift board.
- 4
Pay on time, show the working
A short slip each month showing the count and the gate result. Late or unexplained incentive pay destroys trust faster than a low rate.
- 5
Keep inspectors out of volume pay
Inspectors earn for accuracy, such as audited checks and escapes caught, not for parts cleared.

Review quarterly for gaming
Every scheme invites shortcuts. Ask supervisors and quality what has changed in behaviour, and adjust before the shortcut becomes habit.
Crew name and trades included.
Unit of count: say, rails the galvaniser accepts.
Where and by whom it is counted.
Quality condition: for example, crew sample passes dimensional check.
Safety condition: what breach forfeits the shift's incentive.
Rate or amount, and when it is paid.
How to query a count, and with whom.
Date of last review and next review.Fixed pay first, incentive second
No bonus can rescue a fixed wage that trails the neighbourhood. If welders or soldering technicians are leaving for better fixed pay, the incentive will be seen as a trick. Set the base from a market check, tie it to a skill ladder, and use the incentive only to reward good output on top. Laminator and stringer roles are priced against rivals on the solar panel benchmarking page. Crimping and moulding benches have their own component pay comparison.
Our compensation and rewards practice designs bands, ladders and incentives that fit together. For the handling habits that a better incentive supports, see the post on handling mistakes.
Rolling out a change
Run the new scheme in shadow for a month: calculate both old and new, pay the higher, and show crews the difference. Explain why the gate has moved, using real defects from their own line. Then switch. Expect a short dip in counts while habits change, and hold your nerve, because the dip is the sign the scheme is doing its job.
