Looked at from the other direction, as solar installations go up, the cost per kWh goes down. So a public entity doing one very large installation seems like a good way to help push costs lower, especially for that particular installation. And if they're looking for a lot of urban public space to build on, why not roads?

- fisherjeff 11y agoRight, but that's all structure and doesn't (er, shouldn't) fundamentally affect the cost of the PV cells themselves. Regardless, I agree that it's not necessarily the most cost-effective choice, I just don't think that it's a response to some perceived lack of space either.
