Hey folks,

I'm considering purchasing some Solar Panels to heat my pool. Got a bunch of simple questions for you guys:

1) I'd prefer not installing it on my roof just yet. Can I install these vertically (straight up and down) against my fence, or does it need to be tilted diagonally?
2) Can this be left out in the winter time?
3) I would be installing it myself, however I am hearing that there is a lot of considerations relating to water pressure and something related to the pump head. Is it easy to figure all this out?
4) I have an 18X36 foot pool (I believe). All I can really fit as far as the panels go would be 4X20 or 6X20 worth of panels. I know this is not ideal, but will it make enough of a difference to justify doing this?
5) Until I do install this on my roof (a few years from now) I would have the PVC piping above ground. No issues with that, right?
6) My estimate for pulling this off is in the neighborhood of $1,000 (give or take a few hundred). Would you agree?
7) Is this truly as easy as it sounds to install this?

Thanks a lot!
