Not to throw a damper, but bring some reality is a few facts, which I suspect will be instantly argued with, but none the less.

I will make the logical assumption that this will not include batteries, so this is a solar "assistance" to power generation during sunny daytime, otherwise we would need to include the cost of batteries. We can argue this later, if one wants to, but batteries have a low lifetime relative to the solar cells...

Solar cells have a lifetime of 20-30 years, estimates, because few of the modern day cells have been around that long. So, lets take the expanded guess of 30 years, that means every 30 years all the $5M cells will need to be replaced. Anyone want to guess the economy here ? It is great if the government will pay for it (cheers from the liberals today), but lets think of what this really means, feel good ?
