Solar power costs have fallen hard enough that global utility-scale solar PV averages just $0.044/kWh, while investment topped $500 billion in 2023. At the same time, manufacturing and balance-of-system expenses have been dropping, but regional pricing still swings from ultra-low auction tariffs to much higher US EPC costs. Put those together and the real question becomes how fast prices are catching up with performance and capacity around the world.
