The petrol and coal lobbies are why.

We has so many years to figure this shit out.

My first reaction would be that static panels aren’t efficient at collecting energy relative to the space they take up, compared to one that follows the sun. From the picture you could get one panel facing south at most, one facing straight and one facing the wrong way - and that’s if the canal’s route allows for facing south at all. This is the same issue that killed Solar Roadways.

It doesn’t matter if they’re efficient relative to the space taken, if the space taken is functionally 0 (since the space isn’t used for anything else). The poleward side of an east-west canal could also just be cloth or some other kind of shade to lower install costs!

The issue that killed solar roadways (the covered kind, not the stupid ass embedded kind) is that people would inevitably crash into the support beams, leading to collapses. That means the structure would have to be completely over engineered, increasing costs. Plus, the dynamic pressure waves from the passing trucks and cars underneath plus the fact you need to build it tall in order to allow trucks to pass means it needs to be even stronger. Solar over a concrete river is not going to experience these problems and can be minimally constructed as a failure just leads to them falling in the river, not actually harming anyone.

However, solar panels over bike paths? 10/10, no notes, build now.

This just sounds like solar freakin’ roadways V2.

Are least in California, we have better ways of deploying solar that’s more economical. The issue of storage and transmission is a much bigger problem than generation.

We actually have too much solar sometimes. It’s quite counter intuitive. The grid is a fickle beast.

Not terribly counterintuitive, this has been a widely known issue with intermittent power sources since forever. They’re often feast or famine power sources when the grid needs reliable, and power draw increases when people go home from work, which coincides with the time of day that solar output decreases. Generation is still a problem if we want to ramp up to it covering a majority of the grid, but you’re right that storage is the more immediate problem
