We're not saying $50/month would pay for all the electricity, it would only pay for its replacement costs every 2-3 years. You still need to pay the $20,000 for the solar panels themselves. And it's a misconception that solar panels replace all your electricity needs. Doing the math last year here in Texas, it only covered 20% of my needs in the summer, 75% of the needs in the winter.

You could even replace 100% but the risk there is that most utilities have "no negative net metering" regulations approved by the local PUC that mean if you produce more than 100% of what you use, the utility keeps it for free. This makes installing a system at close to the limit uneconomic (and is also one of the reasons that Germany has more installed solar per capita despite far less favorable solar radiation than the US).
