I've done the math where I live, and concluded it'll never pay for itself even if I exclude maintenance and live in the same house for 30 years (the claimed lifespan of a solar installation). We have roughly the same amount of sunlight as Germany. Were it up to me, I'd rather have nuclear in our state. One of those new thorium reactors maybe. I'd even pay a little more for that, especially if they shut down the remaining coal/gas/oil power plants when nuclear comes online. |

It should be noted, though, that this "lifespan" generally means a reduction of output by not more than 20%, not that you are left with a pile of trash. Depending on technological development, possibly replacing solar panels by then is the economically sensible thing to do, but there is no reason why you necessarily would have to throw away a solar installation after 30 years.
