A module line is a sequence of stations — cell cutting, tabbing and stringing, layup with glass and encapsulant, bussing, lamination, trimming, framing, junction box and curing, then EL and IV testing and sorting — linked by conveyors and a MES layer. Sizing starts from capacity, not from a machine list: a 5 MW semi-automatic line runs the same process sequence as a 1.2 GW automatic line, but station count, automation level, and the number of operators change at every step.\u003c\/p\u003e\n\u003cp\u003eThe expensive mistakes on a module line are rarely machines that fail. They are stations bought at the wrong automation level for the capacity you actually plan to run, and formats frozen too late to change the layout. This page walks the sizing decisions that follow from 5 MW to 1.2 GW.\u003c\/p\u003e\n\u003ch2\u003eWhy 5 MW and 1.2 GW Need Different Machines\u003c\/h2\u003e\n\u003cp\u003eThe process does not change with scale. The handling does. At 5 MW you can accept manual loading at the stringer, manual layup, and batch lamination, because the line runs at a fraction of the cycle time the equipment can deliver. At 1.2 GW the same stations become the constraint: stringer throughput, laminator cycle time, and inline test capacity decide whether the line reaches nameplate output or queues in front of one station.\u003c\/p\u003e\n\u003cp\u003eThis is why two lines with the same station list can differ by a factor of several in cost per MW. The difference sits in automation of material handling, in redundancy at the bottleneck station, and in whether testing is inline or offline.\u003c\/p\u003e\n\u003ch2\u003eWhat Changes at Each Capacity Tier\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003cth\u003eHandling\u003c\/th\u003e\n\u003cth\u003eWhere the constraint appears\u003c\/th\u003e\n\u003cth\u003ePlanning consequence\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e5-20 MW\u003c\/td\u003e\n\u003ctd\u003eSemi-automatic, manual loading and unloading at several stations\u003c\/td\u003e\n\u003ctd\u003eLaminator cycle time, manual layup accuracy\u003c\/td\u003e\n\u003ctd\u003eFewer stations, single shift, room to add automation later\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e30-60 MW\u003c\/td\u003e\n\u003ctd\u003eAutomatic at stringing and lamination, manual at framing and packing\u003c\/td\u003e\n\u003ctd\u003eStringer changeover between cell formats, buffer between layup and lamination\u003c\/td\u003e\n\u003ctd\u003eFormat flexibility matters more than peak speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e120-300 MW\u003c\/td\u003e\n\u003ctd\u003eInline handling with conveyors, MES traceability expected\u003c\/td\u003e\n\u003ctd\u003eInline EL and IV capacity, bussing and layup accuracy\u003c\/td\u003e\n\u003ctd\u003eTesting must keep pace with the line, not lag it\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e600 MW - 1.2 GW\u003c\/td\u003e\n\u003ctd\u003eFully automatic, robot or gantry transfer, MES close loop\u003c\/td\u003e\n\u003ctd\u003eAny single station without redundancy becomes the line rate\u003c\/td\u003e\n\u003ctd\u003eRedundancy and layout decide real output, not datasheet speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFive Stations Where Sizing Goes Wrong\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e1. Cell cutting and scribing.\u003c\/strong\u003e The cutting route has to match the cell technology you will actually run. A line specified around half-cut M10 cells behaves differently once you move to multi-cut or back-contact cells, where the rear pattern has to be respected from the first cut. The \u003ca href=\"https:\/\/www.ooitech.com\/SC-20P-Automatic-Solar-Cell-Laser-Cutting-Machine-High-Precision-BC-Cell-Processing-Equipment.html\"\u003eSC-20P back-contact laser cutting platform\u003c\/a\u003e is one example of cutting selected by cell family rather than by throughput alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Tabber stringer.\u003c\/strong\u003e This is usually the first bottleneck. Busbar count drives the decision: an MBB machine cannot follow a line that has moved to SMBB or 0BB without a change of platform. Match the stringer to the busbar roadmap, not to today only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3. Layup.\u003c\/strong\u003e Manual layup is viable only while capacity is low and formats are stable. Once formats change often, automatic layup with quick changeover costs less than the yield loss from handling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e4. Laminator.\u003c\/strong\u003e Cycle time and chamber count set the ceiling of the whole line. Buying a faster stringer in front of an under-sized laminator produces a queue, not output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5. EL and IV testing.\u003c\/strong\u003e Offline testing is acceptable at low capacity. Above roughly 100 MW, inline testing has to match line rate, otherwise modules wait and the line rate is set by the test station.\u003c\/p\u003e\n\u003ch2\u003eFreeze These Inputs Before You Order\u003c\/h2\u003e\n\u003cp\u003eThe layout is only as stable as the five inputs below.

In practice the cost per MW is decided by four things: the automation level of material handling, the degree of redundancy at the bottleneck stations, whether testing is inline or offline, and how much of the plant work (utilities, floor loading, compressed air, cleanroom class if used) is included in the supplier scope.\u003c\/p\u003e\n\u003cp\u003eTwo suppliers quoting the same station list can therefore differ substantially once scope and automation are aligned. Published cost figures for module lines are a starting point for comparison, not a quotation; the \u003ca href=\"https:\/\/www.ooitech.com\/solar-panel-manufacturing-unit-cost-12-quotes.html\"\u003eunit cost breakdown from 12 quotes\u003c\/a\u003e shows how the same capacity is priced at different scopes, and current pricing has to come from a fresh quotation.\u003c\/p\u003e\n\u003ch2\u003eWhat to Settle Before the Line Ships\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory acceptance test:\u003c\/strong\u003e agree which modules are produced during the run and what data is recorded.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUtilities and floor:\u003c\/strong\u003e power, compressed air, vacuum, and floor loading for the laminator, confirmed against the layout drawing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpares and consumables:\u003c\/strong\u003e a defined first-year spares list, plus which consumables are sourced locally and which are not.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraining and ramp-up:\u003c\/strong\u003e who stays on site through ramp-up, and what the acceptance criteria are for yield at the end of it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImport and installation scope:\u003c\/strong\u003e which side handles clearance, inland transport, rigging and commissioning, agreed in writing before shipment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eIs a solar panel manufacturing machine one machine or a set?\u003c\/h3\u003e\n\u003cp\u003eA set. No single machine turns a cell into a finished module. The minimum viable set covers stringing, layup, lamination, framing, junction box and testing, plus the handling between them.\u003c\/p\u003e\n\u003ch3\u003eWhat is the smallest capacity that still makes sense as a factory?\u003c\/h3\u003e\n\u003cp\u003eSemi-automatic lines are offered from 5 MW upward. Below that, the labour and testing content per module stops being competitive against buying finished modules, so a line at that size is normally aimed at a specific product rather than at general supply.\u003c\/p\u003e\n\u003ch3\u003eWhich station decides the output of the line?\u003c\/h3\u003e\n\u003cp\u003eWhichever station has the longest effective cycle time once handling and changeover are included. In practice that is the laminator on many lines, and the stringer when formats change often.\u003c\/p\u003e\n\u003ch3\u003eCan automation be added after the line is running?\u003c\/h3\u003e\n\u003cp\u003ePartly. Adding automatic handling at one station is normally feasible. Adding inline testing or full traceability later is more disruptive, because the layout and the data points have to be created rather than extended.\u003c\/p\u003e\n\u003ch3\u003eHow long is a module line from order to production?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the tier and on plant readiness. Equipment build, shipping, installation and ramp-up are separate phases, and the last one is usually what slips when utilities or floor work are not finished before the machines arrive.\u003c\/p\u003e\n\u003ch3\u003eDo I need MES from day one?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily, but the decision affects station specification. If traceability is likely within two or three years, it is cheaper to specify the data points now and enable the MES layer later.\u003c\/p\u003e\n\u003ch2\u003eFinal Thoughts\u003c\/h2\u003e\n\u003cp\u003eSizing a module line is a sequence of decisions, not a machine list: fix the capacity tier, fix the cell and busbar roadmap, then choose the automation level that the tier can pay back. Lines that skip the second step end up queueing in front of the stringer or the laminator within a year. If you are comparing offers, send the same five frozen inputs to every supplier and ask each one to state the station list and the scope boundary, so the comparison is between lines and not between quotations.\u003c\/p\u003e","brand":"Ooitech","offers":[{"title":"Default Title","offer_id":67691754061923,"sku":null,"price":99999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/1427\/4659\/files\/w800_h600_fitblur_v2_2026032615911208_50e5a3f6-2626-4c13-b0b7-5f3f6fa7fe08.webp?v=1791858221","url":"https:\/\/ooitechchina.myshopify.com\/ru-global\/products\/solar-panel-manufacturing-machine-stations-and-layout","provider":"Solar Panel Making Machine","version":"1.0","type":"link"}
