Solar power has become cheaper than fossil fuels for electricity.

Is it true that solar power has become cheaper than fossil fuels for electricity?

Partly. Evidence is mixed and only partial: one reference says utility-scale solar was the least expensive source in many countries, and another notes grid parity was reached for solar in some places, while older sources say solar was still costlier than fossil fuels and that renewables need fossil-fuel backup.
