Did you use chat gpt or something because almost all of what you said made no sense in the context of this discussion. I, like most people, don't have a solar panel on my roof and nor is it practical to have one. If large cities are to have enough electricity for all of their energy needs, massive solar farms will be needed. I live in Ontario, Canada, a large area with a relatively small population. In a study looking at what is needed to meet future electricity demand, if we only used renewables, around 2-5% of the area would need to be covered by solar or wind. This sounds small but it is a huge amount of land and would be extremely resource intensive. Much of it would need to be far away from where the demand actually is leading to losses in transmission. Farming under solar panels is also laughable because it would render the farming itself impractical or the solar itself much more expensive because it would need to be on a massive raised platform. I am not sure what you are referring to with mines but Canada has one of the largest uranium reserves located in somewhat remote locations. This does not lead to transmission losses, only costs to transport the uranium ore.
Canadian CANDU reactor units can be online for more than a year thanks to their online refueling capabilities. Intermittent is still intermittent which is why solar needs a way to either store energy or it cannot be the only solution (it isn't).
I am not sure what you mean by grid penetration but CANDU reactors have an average capacity factor of more than 80% which is significantly higher than the less than 25% for solar.
Also, Ontario is currently generating more than 50% of its electricity from nuclear so it can certainly meet more than 10% of the demand if it is suitable for the region.
Where are they delaying decarbonization for the sake of waiting for nuclear? As far as I know, many places are building wind and solar and nothing is stopping them. I am not trying to argue that solar is bad or worse than nuclear. I just think it should be realistically considered alongside of nuclear and any other carbon neutral energy source.
