Yes, your statement is still false. Opposite is true.
The lifetime of solar panels is also higher than most of these analyses say it is, because both solar and batteries are frequently found to last well beyond their factory-rated lifetimes. So I think you’re wrong without any additional considerations here, so let’s leave that aside.
What you’re saying here is that the lower ongoing opex of solar and batteries is eaten up by the higher initial capex of gas, but you’re saying the prive of natural gas has no impact on this calculation.
I don’t think this makes any sense. Can you explain your thinking here? Can you cite any data on this?
No, the industry knows this. Talk to any investor or developer. See the capacity market blowout in PJM because they don't have enough firm power supply to offset the flood of renewables (sans storage). Or just look at the announcements for natural gas turbine demand by datacenters, which need 24/7 power. The overbuild for renewables and storage is insane to hit the same reliability and safety margins.
> So you’re arguing that initial capex (which everyone acknowledges is higher than natural gas) is somewhat higher than existing analyses think it is
It's not just CAPEX. It's also OPEX. LCOE is a normalized ($/MWh) metric that allows for comparison. See Lazard [0] or NREL's analysis [1] on LCOE costs. Note how expensive solar plus storage becomes on an LCOE basis and realistically, you might need way more than 4h batteries to hit reliability targets.

BTW, this is like saying you can still use laptops past their 5 year warranty. Yes, but that's not how depreciation, financing, and service levels work. These assets are getting pushed to their limits and not everyone's buying tier 1 suppliers.
You’re saying the overbuild is “insane”. Do you have an actual cite for this? I’m assuming there’s some percent over capacity you need to build that would allow people to reason about this.
I’m still not seeing an answer here re: the cost of natural gas, it seems like that has a huge impact on all of these assumptions.
