Solar Module Line Quote, Answered Within 24 Hours
Every solar module line quote on this site is written by the engineers who size the machines, not passed through a mailbox. Send cell format, busbar count and target output; an application engineer takes the enquiry from there and stays on it through commissioning.
24HOURS
- Machine selection — named model by model, with the reason each one matches your cell
- Layout direction — where the row sits on your floor and at what docking heights
- Utility list — power, air, exhaust and floor load, so building work can start

If your email client opened, it is already in the message. If nothing opened, use one of the routes below.
Inside the first reply
What a Solar Module Line Quote Contains
Three things arrive in the first mail, not after three rounds of qualifying questions. The span they cover is fixed: from the cell arriving at the scriber to the frame leaving the marker.
Laser scribing, tabber-stringing, robotic layup, bussing, EL and IV test, frame marking. Cells and lamination sit outside it.
A machine selection, named model by model
Only out of the range that carries a full parameter table behind it, with the reason each one matches the cell format and output you gave.
- SML-C72
- Named when BC whole cells at 4800 pcs/h or dual-lane TOPCon/PERC throughput sets the pace.
- SML-C20
- Named when a single cut on 156–220 mm cells at 1600 pcs/h is the whole scribing job.
- SML-S60
- Named for BC strings with negative pitch, −1 to −0.5 mm, at 4800 half cells an hour.
- SML-S40
- Named for 13BB to 20BB TOPCon or PERC where back-side pull force has to hold ≥1 N.
- SML-S15
- Named when 1100 half cells an hour is the real target and the floor is short.
- SML-A6
- Named when layup has to dock at 1230 mm and take strings at 6 seconds each.
A layout direction
- Docking
- 1230 mm where the string leaves the stringer and meets layup
- Glass
- 950 mm ±50 in and out of the layup station
- Clear run

- Format
- Drawings, layout files and photographs travel by email attachment
- Window
- From the first reply through to commissioning, in both directions
Something concrete to react to
One Starting Machine, Model by Model
The first reply names a starting machine for whichever route fits, so there is a real object on the table at the first reading rather than a range of possibilities. Each of these six carries a signed parameter table; the figure beside it is what acceptance is measured against.
Send the one line under each card and the selection can be confirmed or replaced on the next exchange.

Three enquiry routes
New Floor, BC Conversion, Single Station
Every enquiry lands on one of three routes, and each one is answered from a different starting point. Pick the route below and the panel lists exactly what makes the reply useful on the first pass.
The panel
- Cell technology — BC, TOPCon or PERC
- Cell edge 156–220 mm, thickness 110–220 μm
- Busbar count 3BB to 20BB, and whether 25BB is planned later
- Half cells or thirds; cells per string; strings per panel
- Module 1650–2500 mm long, 990–1450 mm wide
- String length 540–1400 mm; pitch +1 to +5 mm, or −1 to −0.5 mm on the BC machine
The building
- Annual output target in megawatts, or panels per hour
- Clear height under the roof
- Floor flatness and load
- Bay length available for the row
- Where power and compressed air enter the shop
What runs today
- Cell format and busbar count currently in production
- String length and pitch currently set
- Hourly output the row holds
- Which stations are yours to keep
- The layup station matters most — docking height to the stringer, glass conveyor height, module sizes it already handles
What changes
- Whether the conversion covers scribing, stringing, or both
- BC cell format and thickness you will buy
- Busbar count, and whether negative pitch is wanted
- String length the new panel needs
- Tooling you hope to keep, and the shutdown window you can give the row
- Any inline string appearance or EL inspection already on the floor — both are options on our stringers rather than fixed content
The neighbours
- Which station is being added — scriber, stringer or layup
- The machine upstream and the machine downstream
- Their outfeed and infeed heights
- The takt each of them holds, so the new station is not the slowest one
- Cell format, busbar count and string length the row runs today
- Output reached today against the output wanted after the addition
From the floor
- Clear footprint left for the new machine, and the height available
- Power drop and air point nearest that position
- Exhaust route
- Docked to a neighbour, or standalone
- For docking to layup: the layup station height and outline dimensions are what we work from
One sentence is enough
One Sentence Starts a Solar Module Line Quote
An enquiry can be a single sentence, and it is answered the same day it is read. Answer the parts you know, leave the rest, and the selection is refined on the next exchange. Nothing on this page has to be complete before writing in.
CellBC, TOPCon or PERC, and the edge length
Busbars3BB to 20BB, or the count you plan
OutputPanels per hour, or megawatts a year
After the first reply
From First Reply to Technical Agreement
Between that first mail and a signed technical agreement, the work runs in a fixed order. Each step closes before the next opens, so nothing is assumed and nothing is renegotiated twice.
Production cell samples and string information reach us within 5 to 10 working days of the contract, and tooling is cut against them.
Blueprint cell fixed
One format the machine will be built and accepted around, with the drawing signed by you.
Model and tooling set
Both follow from that format. Any second format inside the compatibility window is listed as a tooling change, not assumed.
Parameter table agreed
Negotiated item by item. Acceptance is measured against the table and nothing else.
Layout and utilities pinned
Footprint with operating space, docking heights, feed cross-sections, hose count, exhaust ports, floor load.
Samples in, tooling cut
Production cells and string information arrive; tooling is cut against the real material, not the drawing alone.
The agreed table, layout and utility list become the technical agreement. There is no second document that quietly outranks them.
Acceptance, not adjectives
The Table Acceptance Is Measured Against
Eight rows decide whether a machine ships. Each one carries a figure and a method, agreed before the build starts and checked on your own blueprint cells at run-off.
| Parameter row | Figure written in | How it is judged |
|---|---|---|
| Positioning deviation | ≤±0.05 mm on SML-S60 and SML-C72; ≤±0.1 mm on SML-S40 and SML-S15 | Measured across a continuous run of your blueprint cells |
| Angular deviation | ≤±0.04° | Same run, logged string by string |
| Soldering pull force | ≥0.5 N front; ≥1 N on the back side of SML-S40 | Pull test per busbar; at most one point per ribbon below 0.5 N |
| Cell pitch and tolerance | −1 to −0.5 mm or +1 to +5 mm, held to ±0.3 mm | Measured on finished strings, not on the setting screen |
| String straightness | ±0.5 mm | Measured over the full 540–1400 mm string length |
| Breakage rate | ≤0.25% stringing; ≤0.05% scribing | Counted across the whole acceptance run, A-grade cells |
| String defect and rework | ≤3% defect; ≤15% rework | Appearance and EL check on the same run |
| Uptime | ≥95% | 1 − unplanned downtime ÷ 24 h, over a continuous 24-hour day |
Swipe the table
One blueprint format per machine. A second format inside the compatibility window is a tooling change, priced and listed, never silently included.
Uptime is defined once and used everywhere: unplanned downtime means fault or abnormal stop, measured against a 24-hour day.
Before the machine is yours
Assembly Floor Visit and Run-Off Witness
Two visits are worth asking for, and they show different things. One judges how a machine is built; the other judges whether it does what the table says.
Assembly floor visit
- You see
- Machines in build and machines in commissioning, side by side
- You judge
- Fit and finish, cable and pneumatic routing, and how a stringer is set up before it ever sees a cell
- Honest because
- Half-finished machines cannot be dressed for a visit
Run-off witness
- You see
- The machine run on your own blueprint cells, taken through the table item by item
- Items checked
- Positioning deviation, soldering pull force, cell pitch, breakage rate, continuous uptime
- If it misses
- Back to assembly, not onto a truck. Results reach you either way
Arranging either visit
- Name the model or project involved
- Say what you want to see — build, commissioning, or a run-off
- Give the number of people travelling
The schedule comes back with the build stage the machine will be at on those dates, so the trip lands on something worth watching.
Three clocks
24, 48 and 72 Hours
Three numbers hold for every enquiry and every installed machine. They are separate clocks, and each one starts on a different event.
24HOURS
First reply to a new enquiry
Written by an application engineer, carrying a machine selection, a layout direction and a utility list.
48HOURS
Response to a written notice
On a machine already installed, from the moment the written notice reaches [email protected].
72HOURS
Solution issued for that notice
A route out, not an acknowledgement: parts, settings, a field visit, or a combination of the three.
Every machine carries one year of free warranty with lifetime repair service from handover. The clocks above do not stop when the warranty year ends; the repair service does not either.
Same address, faster clock
Support for Running Machines
Machines already installed reach us at [email protected]. A first message that carries the five items below usually skips an entire round of questions.
Field service covers installation, commissioning and repair, on machines of any age.
- Model and works numberBoth are on the machine nameplate.
- Station and alarmWhich station, and the alarm or message showing on the screen.
- What was runningCell technology, cell size, thickness and busbar count at the moment it happened.
- When it startedAnd whether it repeats, or happened once.
- Photographs, or an EL imageOf the affected string. One image usually settles what a paragraph cannot.
Training sits inside this too: free before acceptance, once and up to twice, 10 hours on the floor split as above, plus 3 hours of commissioning and safety instruction.
Carried by us
- One year free warranty, then lifetime repair service
- Installation, commissioning and repair by our own field engineers
- Wear parts kept available for as long as the machine runs
Charged as a service
- Travel for on-site service outside our home market, and freight on parts either way
- Wear parts themselves — suction cups, springs, filters
- Damage from misuse, operation outside the stated conditions, or force majeure
Drawings, layout files and photographs travel by email in both directions, from the first reply through to commissioning.
