Alt Energy to power the tank

[Chad]

Hi, I have been looking into getting some solar panels to run my tank's pumps etc. Has anyone else tried this or thought about it? I was thinking I would have the tank run off the panels during the day, weather permitting, and as the power dropped off have it run off of the house electricity. Is it even feasible to seamlessly transfer to the house power? I only just recently began looking into it so I am not entirely positive I can even make it work.

Thoughts?
