I was thinking about a solar set-up a few days ago.  I'm glad someone else is also looking into this. 

I was wondering about what happens after the sun goes down.  My idea was to lay the solar panels on my back patio.  I have flood lights that turn on/off at dusk & dawn.  I was wondering if I put the panels in a place where they'd be lit up by the flood lights, if that would allow enough power to flow into the battery overnight to keep it from running dry.  And the flood lights are 15 watt LEDs.  I guess it sounds too good to be true... using a 15 watt LED, solar panel, inverter, etc., to power an 850 watt PSU & Antminers.
