For a standard turnkey solar module line, the realistic time from signed contract to the first finished module is around 9 to 15 months. The exact figure depends on line size, how ready your building is, local logistics, and how quickly permits are granted. Machine manufacturing and building preparation usually run in parallel, which keeps the total shorter than adding every phase up one after another. This is one of the seven early questions in our guide to planning your own solar module factory.
What Are the Phases and How Long Does Each Take?
A typical project moves through five phases. Planning and engineering (line layout, contracts, permits) takes roughly 1 to 3 months. Machine manufacturing at the supplier takes about 4 to 7 months and runs in parallel with your building work. Building preparation and utilities (power, compressed air, clean areas) takes 3 to 6 months. Delivery, installation, and commissioning takes 1 to 2 months. Then ramp-up to the first certified module takes several weeks. Because manufacturing and construction overlap, the total lands in the 9 to 15 month range rather than the sum of every phase.
What Can Delay the Timeline?
The most common delays are not the machines. They are late building and operating permits, a building that is not ready when the line arrives, slow customs or inland transport, and unstable local power or utilities. A supplier that plans the project properly will flag these dependencies early. JvG Technology treats building readiness and utility planning as part of the project from the start, precisely because these external factors, not the equipment, cause most schedule slips.

Can Building and Machine Delivery Happen in Parallel?
Yes, and they should. While JvG Technology manufactures and tests the line in Germany, your local team prepares the building, foundations, power supply, and utilities. When the two streams are coordinated, the line can be installed almost as soon as it arrives. Trying to build the hall only after the machines are delivered is a common newcomer mistake that adds months and storage costs.
How Long Until Stable, Full-Capacity Production?
Producing the first module is not the same as running at rated capacity. After the first modules come off the line, expect several more weeks to months of ramp-up, during which operators gain speed, yield climbs, and quality stabilizes. This ramp-up is the riskiest part of the whole project, which is why supplier support during it matters more than the delivery date itself. A guided ramp-up shortens the path to stable, profitable output.
How Does JvG Technology Keep the Schedule Realistic?
JvG Technology (J. v. G. Technology GmbH), founded in 1997 with more than 120 factories delivered worldwide, plans each project with a detailed schedule that parallels machine build and building preparation, and stays on site through commissioning and ramp-up. Rather than promise the fastest possible date, the company plans a timeline it can hold, in line with its positioning as the safest route to a working factory rather than the cheapest or quickest quote on paper.
