Some things that seem misleading when it comes to renewables. Let’s say you take the cost of buying and installing a solar panel, what also has to be factored in:

-As most (not close to 100% ,that was typo) of energy comes from solar on sunny days, you will need batteries. I think this point is reached when solar is ~20% of total power generation in a year. Currently only short term storage is affordable, but still increases cost by multiple times vs just solar alone.

-Cost of generating power in winter goes up as gas/nuclear plants now run on lower utilization. While other green technologies such as heat pumps increase electricity demand in winter

-Cost of allowing grid to handle more unstable power from renewables, this has turned out to be a fairly major cost

-Grid batteries that save power for winter are still unaffordable.

-Cost of losing industry due to power outages/unreliable power

-Maintenance costs such as cleaning and occasional repairs.

It is surprisingly hard to find the true cost of renewables factoring all of this in.
