Why not just get a solar PV system and a variable speed pump? On top of that, you can get a solar blanket to keep the heat in. That seems to be a better option, since the solar PV system also provide power to the rest of your house instead of just your pool pump. A variable speed pump will help drastically reduce the energy usage. A solar blanket will help keep the heat in the pool and to keep the pool ~5 degrees warmer normally, which will reduce the amount of gas needed to bring the pool temp up.

I still need to see what type of pump I currently have. I believe it is variable speed but will reconfirm. I don’t know if the pool cover is “solar blanket” or not. It’s an electrically operated cover (blue and on roller). Bit of a pain actually – the cauter pin broke the first week we moved in.
My interest on just going with a pool solution was sparked by:
1) Pool heating and pumping seems to be the main part of the bill anyhow.
2) The idea of the whole thing being off the grid appeals to me. Also, I’m not 100% confident that the rules for PV systems selling electricity back into the grid won’t change. But you’re quite right – I need to look into it more. Doing the basic research is quite challenging (at least to me).

I had a Pentair Intelliflo and for most of the year, I have it on speed 2 running for 8 hours a day during the winter/spring/fall and 12 hours a day for summer. I only turn it on speed 4 for a few hours to turn on the heater. It heated my entire pool in ~4-5 hours (on the first day, 2-3 hours on subsequent days) and it last the whole day . My electricity bill without solar PV with those settings were around $150-450/month (depending on how often I use the pool heater and turning the pump on to 4. After solar, my electricity bill were around $5-90/month with similar usage.

AN, we’re having solar contractors come out this week to give us some bids. We have a very old-school pool pump plus a second pump for the pool vacuum which, I believe, are costing us a lot of money. We would have followed OCR’s recommendation to just change that out before getting solar panels — and plan to do that eventually — but we also LOVE air conditioning, so the solar panels are pretty much a must for us.
We use very little gas, even in the winter, because we like it very, very cold, but the summer electric bills are killing us!
I was wondering if your bill, especially the one closer to $450, included any air conditioning or if it’s just the pool pump (or gas?) that runs it up so high. Also, what size solar system do you have? Anything you wish you had done differently now that you’ve had your system for awhile?

Your old pool pump might be taking 50 KWh per week if you’re running it 8 hours per day so each hour it’s running would be about 0.9 KWh. A newer one might be closer to 0.3 KWh.

April 23, 2014 at 2:35 PM #773246anParticipantCAR, the $450 is pool and AC running during the summer. During the winter, where its just the pool pump and household usage, its about $150-$180. My solar system us 3.8kWh. Nothing I would do differently.
