Reply to comment by ShankThatSnitch in Researchers: Floating solar panels could provide over a third of global electricity by TurretLauncher

I’m surprised to hear you say you work at a public power company while also imagining that local solar could power local things and “runoff” could be sent elsewhere. That isn’t how electricity works at all. You can’t control where an electron goes once released into the grid and the frequency needs to be maintained within a very narrow range so the load needs to exist at the same time the energy is created. Having solar on your roof doesn’t mean you get “your” electrons powering your house.

I’m not really sure we can continue this when you’re going to say “yes but storage” .. electricity going to storage is also a load — i.e. we can have more solar when we’re prepared at utility scale to need it .. why would we build utility’s scale batteries and also not build the utility’s scale solar to go with it but still have any need to put thin film everywhere. Regardless of progress, distributed solar will never be cheaper than utility because distributed has unique installations that don’t benefit from scale or learning.

You are assuming some weird scenario where we build out local solar, with none of the other components in place. Obviously, anywhere that local solar would be installed would be accompanied with bi-direction meters, micro-inveters, and possibly even local storage.

As for grid vs. local, decisions would be made based on cost, land availability, the grid itself. This will take years and more innovation. You keep glossing over that point where I say this is not a today thing, but something that could happen over decades. Please explain how you k ow what technology will be available 1-2 decades from now?

I am just a web developer, and my point about the company I work at, is not that I am some electricitiy expert, but that I hear the challenges brought up frequently in conversation and company meetings. These are main issues being worked on as we speak, but it is a slow-moving process. And again, solar is only 3-4% of electricity, so all the other stuff that is needed, will be worked on as we scale.

I’m sorry you don’t fundamentally understand the grid.. bidirectional meters don’t help with management of the power, only payment. And they generally are associated with net metering which increases the price of electricity enormously for everyone without panels. It’s an extremely regressive policy.

Take a listen to The economics of rooftop solar if you want to understand more on this particular issue.

Otherwise I hope you have a great day. I’m stepping out of this discussion here.
