Why Ars Technica called modern solar "Offensively Cheap":
Between 2010 and 2024, utility PV module prices plummeted over 90%. Even when pairing 4-hour battery energy storage systems (BESS) to turn intermittent daytime solar into dispatchable peaker replacement power, the combined levelized cost of energy ($49.92/MWh in benchmark conditions) undercuts new combined-cycle gas turbine and coal generation across the majority of global grids.
