Glass-laminated photovoltaic panels.
Overview
PV farms tile land or water with modules, often on trackers. Inverters convert DC to AC. Transformers raise voltage for collection and transmission.
How it works
Photons generate carriers in cells. Strings of modules feed inverters. Plant controllers follow grid codes for voltage and frequency support.
