PART 2: HOW AUCTIONS HELPED SOLAR BECOME THE CHEAPEST ELECTRICITY IN THE WORLD
This article is the second installment in a two-part series. Unit-cost solar electricity for less than two US cents per kilowatt hour (kWh) is the cheapest electricity in the world, but most of the recent ultra-low bids in the global solar market likely required the stars to align to breach this barrier. Using very high efficiency or bifacial modules in some of the sunniest parts of the world, combined with aggressive forward module pricing and system cost assumptions, a transparent and supportive national policy environment, and access to concessional terms for finance, taxes, land, or labor, has driven capital expenditures down significantly.
