Line Design & Engineering

We engineer the lines
that build and save solar energy

SIEMER ENERTEC designs and engineers production line equipment across the complete photovoltaic value chain — ingot and wafer, cell, module — together with inverter and BESS assembly lines and the automation layer that ties them together.

Our Scope

Equipment engineering across the whole chain

We are not a module maker and we do not sell inverters. We design, engineer and supply the production lines our customers use to manufacture them.

SIEMER ENERTEC scope: ingot and wafer, cell and module lines, plus inverter and BESS lines, on an integrated automation layer
Six Capability Areas

Production lines we design and engineer

Each line can be supplied as a standalone project or combined into a fully integrated, automated plant.

Cell Technology Routes

TOPCon, HJT and BC, engineered, not assumed

The technology route determines the equipment set, the thermal budget, the cleanliness class and the module interconnection method. We design the line around the route you commit to, and keep an upgrade path open where the process allows.
