You are confusing capacity costs (capital outlay) with utilization costs (what you actually pay per watt). Its true that renewables have a very low cap cost. They are also several times the utilization cost. That's why electricity in CA is 2-3x what it was just 10 years ago. And energy prices are basically the same as 10 years ago.
PS LCOE is a BS stat used to confuse those that don't understand energy markets, not a real market calculation that anyone pays.
