Solar Pool Pump
Anyone ever use a Solar Pool Pump (such as the one on this page http://www.sunrayus.com/)?
The idea sounds good. There isn't enough information (or I haven't dug in enough) on the page to see if it makes sense (real price of the unit), but if my pool pump can run from the Sun when available, why not?
What are the downsides? Does it switch to the grid when there isn't enough sun?
I live in the Northeast, so I understand the sun isn't like it is in Cali or Arizona, but any little bit will help. I am all for long term investments that will pay off (and make me feel less guilty about running my pool).
