The main distinction exists between the size and intricacy of these systems. The process of installing small project solar panels requires roof-based systems and basic ground-based mounts that need minimal civil and electrical work. Utility-scale solar power plants need industrial-grade civil engineering work for their massive construction which includes large-scale land preparation and foundation pile installation across hundreds of acres and high-voltage substation development for grid connection. The installation process demands the precise organization of numerous components while managing extensive workforce teams during prolonged periods which creates substantial regulatory and financial and construction challenges beyond what smaller decentralized systems face.
