A full worked design overview of a 500-acre, 100 MWdc ground-mount solar farm — module and tracker count, a single-axis-tracker-vs-fixed-tilt capacity factor comparison, the power-block inverter and collection architecture, and the multi-year utility interconnection study process.
The project brief: a 500-acre former agricultural parcel is being developed into a 100 MWdc utility-scale solar farm interconnecting directly to the regional transmission grid. Framed as this program's largest-scale project, it's the one real project where the racking choice, inverter architecture, and interconnection process all operate at a scale and through a regulatory process a rooftop or commercial system never encounters.
This module walks the whole design the way a real utility-scale developer would: the module and tracker count worked from the DC capacity target, a single-axis-tracker-vs-fixed-tilt capacity factor comparison, a 256-inverter power-block and MV collection architecture, and the multi-stage Large Generator Interconnection Procedure a project this size has to complete before it can deliver a single kWh. The full worked numbers, complete bill of materials, and finished design reasoning are part of the unlocked module below.
