Does that account as well for the longevity of it? The current nuclear reactors lasted around 40 years already without much issues, I wouldn't bet the solar installations to last that long.

Solar installations are generally rated for a 30 year life, so ¾ of nuclear isn’t bad, especially when you add in decommissioning costs which are going to be a lot lower for solar

When you hear "nuclear reactors last for 40 years" you should instead hear "nuclear technology improves at such a slow pace that it's reasonable to talk about 40 year lifespans". Almost no one cares if your desktop computer can last 40 years. And PV is improving so fast that making it last 40 years would be nearly as pointless.

  Cost of products are averaged for their lifespan, if the solar panels only last 10 years, they need to be 4 times cheaper than nuclear to be at the same price per year. And nuclear does not improve in a "slow paced", I don't know where you got that impression, there's been a lot of innovations on the last 10 years.

    Nuclear technology has improved in cost in the past decade by a factor of 6, like PV has? If not, I will call its rate of improvement "slow".

      that's not how percentages are working... There's clearly some math issues here... And the latest generation of plants are already 20% better than the previous ones.
