...solar electricity is some 20-50% cheaper today than the IEA had estimated in last year’s outlook... depending on the region.
In the best locations and with access to the most favorable policy support and finance, the IEA says the solar can now generate electricity “at or below” $20 per megawatt hour (MWh). It says:
“For projects with low-cost financing that tap high-quality resources, solar PV is now the cheapest source of electricity in history.”
That is according to the International Energy Agency’s World Energy Outlook 2020.
