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.

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.

It’s not just a matter of creating energy but of managing the grid. The power on the lines needs to be balanced with the load in real time second by second. Generation sources need to be shut off and turned on to make that happen but solar panels are difficult to impossible to shut off. More or less they need to be covered physically which can’t be done on distributed solar.

During much of the day real time electricity prices are actually negative. We don’t need radically more day time electricity from slapping thin film in every place we can think of. The priority needs to be on the ability to manage the grid or else we force more stable, lower or no carbon sources of energy offline & need to rely on natural gas peakers for the dark hours when we have most energy demand. The combo of just solar & natural gas is potentially worse for the environment than no solar but better managed non-renewable plants.

Don’t confuse this with me being against sustainable energy. The grid management aspect of solar is just really poorly understood and leads to a lot of pressure for things that don’t align with the real goals.

Utility scale solar (putting all the panels in one place) has enormous advantages over distributed solar (putting panels in random places all over). With the costs averaged out, energy from distributed panels can easily be 10x more than solar energy that comes from utility scale locations. Higher energy prices are regressive, meaning they hurt the poor more than they hurt the rich, and imo should not be encouraged when a cheaper option exists that is environmentally similar.

Also research the duck curve. Until we solve storage, there are certain places that shouldn’t have more solar installed.
