    600 watts but a lousy spec sheet - they only give the max for head and flow which are at opposite ends of the pump curve

    What ever they claim, you can divide it by 2 or 3. My pool pump costs about 30-35 bucks a month to run....not what they claim.

    But saving 30 bucks a month would add up pretty quick. 30x12= $360 a year.......$3600 over ten years....not counting inflation...but wait...there's no inflation, right? Ask Obama's crew. I be the system costs about 2 to 3 times that.

    The good old "call for price" is the killer. You know they want to send out a salesman to scope out the situation etc. which is fine ...but they should at least give some examples instead of the crazy "claims".

    I'm no solar expert but I am a pool expert.
    There is now on the market a soalr PV pool pump (I forget the name but I'm sure you can google it). It uses a DC water pump and they simply size it so what ever sun you get is enough. No fancy controls, no sun no pump and they run around $4,000.00 or more. Now you see why I haven't looked into it much.
    You would do better to look into a 2 speed pump or the newer variable speed pumps. They run in the 1200 to 1800 dollar range and at 15 cent a KW boast a 3 three year ROI. The motors claim to be so efficient that even at regular speeds (3250 rpm) they coast 30% less to run than a standard pool pump.
    CA and FL now require them on new construction so they should be easy to locate.

    Larry any idea of how much power these pumps use? How long they need to run each day? I would expect them to come in various sizes?

    Skunking,

    The Company I'm trying to work with hasn't provided much information. They did say for the 5,000 gal pool we're working with they needed 2- 100 watt panles to achieve 36 gpm. It's been very fustrating dealing with this company and I'm about to look into puting a system to gether my self if they don't come through in the nex 2 weeks.

    I would expect that yes they do come in differant sizes. The industry standard used to be one turn over in 8 hours but that has changed some with the new energy laws coming in. We're now looking at meeting two standards ansi/apsp 5 which says max water volocity would be 8 ft per second in suction lines and 10 in return lines with a turn over rate of at least 12 hours. And ansi/apsp 15 which limits these to 6 and 8 respectively for the primary filtration and t urn over rate not to exceed one in six hours. In addition the pumps must come from a national data base.

    Of course the ansi/apsp 15 does not apply if your using a solar pv powered pump.

    Those are low turn over rates. On commercial pools here we need to turn over every 480 minutes and on a wading pool about 1/2 that time. been a while since I did one but that is what I remember.

    Larry no offense offered but that is a RED FLAG WARNING something is very wrong.

    Something on the order of we have a car that gets 50 mpg, room for 6 large people, luxury with all the Bells and Whistles.

    Naptown,
    480 minutes is an 8 hr turn over rate, right in the middle of the range I stated. That was for residencial pools, the reuqirement in FL for commercial pools is 4 turn overs in 24 hrs or 1 every 6. And yes wadeing/splash pools have a much higher turn over requirement.

    Sunking,
    No joke. Unfortunately it's not my deal there's a third party involved. I am how ever already looking into other options including the one mentioned above. Unfortunately it won't allow us to vaccume the pool. This only needs to be a recirc pump for 5000 gals. The pool also has a vanishing edge but that is served by a high volume low head lift pump I already have installed.

    I had a client run panels straight to a DC pool pump and it works great. Send me a private message and i'll put you in touch.

    Default Solar pump

    Any one interested in purchasing a solar powered pool pump needs to check out the solar flow 2 at www. want cheap advertising.com The pump can be purchased by itself, or as a turn key kit including panels, pump, motor and electrical box. this system is very easy to install and is a stand alone system. no grid connection.
    1 horsepower version is capable of 82 gallons per minute. A very reliable and reasonably priced unit.
