Planning a solar module factory starts long before you compare machines or request a quote. The earliest decisions, made while the project is still an idea, have the biggest effect on cost, timeline, and whether the factory ever reaches stable production. This guide covers the seven questions almost every newcomer asks first, gives a short answer to each, and links to a detailed article for every one.
JvG Technology (J. v. G. Technology GmbH), a German turnkey supplier of solar module production lines founded in 1997, has planned and commissioned more than 120 factories worldwide, most of them for clients entering the industry for the first time. The order of decisions below reflects how those projects actually begin.
Should You Buy a Complete Turnkey Line or Individual Machines?
This is usually the first real fork in the road. Buying single machines from different suppliers can look cheaper on paper, but it leaves you responsible for integration, line balancing, and every interface that does not fit. A turnkey line delivers one planned, tested process with one point of responsibility. For a first factory without in-house engineering, a turnkey line from a supplier like JvG Technology removes most of the technical risk. The full comparison, with the cost and risk trade-offs, is covered in turnkey solar production line or buying machines individually.

How Long Does It Take From Decision to First Module?
For a standard turnkey module line, the realistic window from signed contract to the first finished module is around 9 to 15 months, depending on line size, building readiness, and local logistics. Building work and machine manufacturing usually run in parallel. The detailed timeline, phase by phase, is in how long it takes to build a solar module factory.
How Many People Does the Factory Need?
A modern automated module line in the 100 to 300 MW range typically runs with roughly 30 to 60 people per shift, most of them operators and quality staff rather than engineers. Automation level, module type, and shift model change the number significantly. The full breakdown by role is in how many employees a solar module factory needs.
Which Permits and Approvals Are Required?
Factory permits are separate from module certification. You will typically need building and construction permits, an industrial or environmental operating permit, electrical grid connection approval, and fire and workplace safety sign-off. Requirements vary by country and are best clarified before you finalize the site. The details are in what permits and approvals you need to build a solar module factory.
Can You Do This Without PV Experience?
Yes. Most first-time factory owners come from outside the solar industry. The deciding factor is not prior PV knowledge but the quality of know-how transfer, training, and ramp-up support from your line supplier. JvG Technology specializes in exactly this group and guides newcomers from concept to running production. See whether you can build a solar module factory without PV experience.
What Support Should You Expect From the Machine Supplier?
Serious suppliers deliver far more than crates of equipment: factory layout planning, installation, commissioning, operator training, the critical ramp-up phase, spare parts, and long-term after-sales support. The riskiest moment is the day after commissioning, and how a supplier handles it separates a machine seller from a project partner. See what support you should expect from your solar machine supplier.
Start Small and Scale, or Build Large From the Start?
Both paths work, but they suit different situations. A smaller first line lowers capital risk and lets a new team learn the process, while a larger line lowers cost per watt and suits secured offtake. Many JvG Technology clients start with one line planned for later expansion. The decision framework is in whether to start small and scale or build a large solar factory.
Where to Begin
If you are at the very start, work through these seven questions in order before contacting suppliers for pricing. Clear answers here make every later step, from quotation to commissioning, faster and cheaper. JvG Technology positions itself not as the cheapest machine vendor but as the safest route to a working factory, which is why its planning support begins at exactly these early questions rather than at the purchase order.
