I think you are dreaming on some propaganda instead of seeing the actual tech. We have effective storage with pumped hydro, where we can, witch is "somewhere" but far from being enough. All the rest is experimental and NOT promising at all beside propaganda.
So, with my small p.v., witch I can double and I will do, but remaining far from autonomous I simply relay on nuclear and fossil power plant. Because that's the reality at scale.
My power needs are far less than industry needs, hospitals needs etc.
Specifically on string output: floating p.v. means panels who can move even if only a bit, witch means if not used on micro-inverter systems, their DC current output going crazy.
- pencilguin 4y agoThe operators of the many GW of floating PV in use seem to have solved your string problem, assuming there was any. My guess, not. Any competent engineer can design a perfectly workable utility-scale energy storage system. All that is uncertain is which designs will be cheapest, or otherwise most practical. (There are many kinds of cost.) Experience will identify the best. We have lots of pumped hydro storage because we have lots of hydro generation easily retrofitted with a pump. Other utility storage is not being built out much yet because it would be stupid to build storage there is not renewable generation to charge from, and utility operators are not generally stupid. Small battery arrays that shift just a small excess of energy from midday to early evening, and otherwise stabilize grid fluctuations, have been massively successful.
