How did solar power get cheap? Part I - by Brian Potter

Solar photovoltaics (PV) have become one of the cheapest sources of electricity. Lazard’s estimate of unsubsidized levelized cost of energy (LCOE)

(Note: unless noted otherwise, quotes are from John Perlin’s “From space to earth: the story of solar electricity”) Solar photovoltaics (PV) have become one of the cheapest sources of electricity. Lazard’s estimate of unsubsidized levelized cost of energy (LCOE), the average cost of electricity generated over a plant’s lifetime, has utility scale solar PV cheaper than anything except completely depreciated natural gas plants and wind in the very windiest locations. Data from the Energy Information Administration (EIA) likewise shows that new solar PV plants in the US generate electricity…
