Solar isn't free. You are simply buying the lifetime power output up front.
(Total purchase costs + total lifetime maintenance cost) / (lifetime power produced = cost per kWh.
That's true. You're right, it's not free. It just gets less and less expensive the longer it runs... but it could need replacement too. I suppose I didn't look at it this way-- thanks. You have helped me come to grips with the modern power grid and not waste my time and money lol(Total purchase costs + total lifetime maintenance cost) / (lifetime power produced = cost per kWh.

What about using the wasted electricity to heat your shower water? Or to cook?
How would one do this?Quote from: J35st3r
The issue with solar power is the need for 24x7 uptime on your rigs (your ROI would drop precipitously if you only ran them during the day when the sun is up). So you're looking at battery backup, which at a rough guess doubles the cost (plus maintenance and replacement every few years), or a grid-tie system (in which case you're only running on solar for roughly 25% or your power).
Just putting those issues out there for you to consider. Good luck!
Good points. I guess I was imagining a grid-tie-in system with battery backup, so it would run off the house's electricity at night when the battery power ran out. Just putting those issues out there for you to consider. Good luck!
