Yea, add in molten salt and they can almost get apoximatky PV capacity factor just even more random due to slight cloud cover being such an issue.  Though, you will note 52% still needs backup power all for the low low cost of 13.5 cents per kWh vs sub 4 cents per kWh for PV. You can get PV + storage for 24&#x2F;7 operation for less than 13.5 cents.<p>PS: Which is why most places gave up on molton salt in the first place and burning stuff is the real backup that you know actually works.
