>it just has to charge a battery (or some other means of energy storage) which is reliable. That's not true. Let's say you build your system with enough solar panels to fully charge batteries that lasts 3 days. And lets say sun doesn't shine for 4 days, which is not uncommon. Where is your reliability? Lets say you are designing a system to have reliable power. How many days worth of power backup would you design it to support? >Also worth mentioning (at the risk of being very pedantic) that solar is technically nuclear power. Yeah, and fossil fuels is solar. I don't see how it's worth mentioning.
