How many Solar Panels required for running 2 hp motor pump

I want to know how much energy required to run 2hp pump on solar panel?
How many energy is generated by single solar panels and how many panels required for running 2 hp pump 6 hrs per day

    Welcome to the forum Joshiashay,

    Can I ask you a few questions? First, do you need to pump only when the sun is shinning? If so, you can avoid a battery bank, inverter, and solar charge controller... This will save something like 50% to 75% of the installation and operating costs of the systems. Batteries tend to be expensive, and only last 5-7 years, and need maintenance.

    There are pumps that are designed to connect directly to solar panels. And becoming more common are "VFD" (variable frequency drives) that take solar power in and make 3 phase power coming out.

    For larger systems (2 HP is pretty large), you are generally better off using a VFD type unit and 3 phase pump. The direct attach pumps are generally in the ~1 HP range and, while very nice pumps that will last many years, they are not cheap--And may not be easy to get in your region of the world (India?).

    Some discussions about VFD (Variable Frequency Drives)... Basically a variable frequency inverter with (typically) three phase output. Used to soft start motors (handy for 3 phase well pumps, or pumps with well head starting capacitor) and can also turn an AC motor into a variable speed motor (very handy for pumping applications).

    Here is a Grundfos at the store here. 71 gallons per minute at 100 feet of head. I shipped one to India but they were available there.

    It will only run when there is good sun unless you use a generator. I think we used a 300Vdc array and 2KW to get the voltage up. It could have been less solar. The more solar power, the higher chance that this will work in marginal weather.

    Think I might use a generator for that chore.

    And there are those who do not want more "chores" than the minimum B)

    Living off the grid has so many chores that plenty of exercise is almost assured. Most of the time....I like the life style. But I sure do miss satellite TV, good internet, and a phone that always works. A lot of developed countries really accommodate country livers. USA? Closing the post office's.....essentially slashing the throats of country and small town residents in many ways.

    Note:

    The links in my above post are presently broken (after the forum software upgrade).... Vanilla support is working on the problem.

    I would like to. Know how many solar pannels may be required to run a 24v submerged motor??
  • mcgivormcgivor Registered Users Posts: 1,214 ✭✭✭✭
    Welcome aboard, firstly it's better to start a new discussion including all the details of what you propose to achieve, the details of the motor, a 24V motor is not much to go on, you need to provide at very least a current requirement and what the motor actually dose, without details nobody can answer your question.

    Things are a bit slow today so I'll play around here. This isn't really a panel equation. Inverter size is the biggest question along with wire sizing. 2HP is a beast of a pump, I think, for sure, 220/240 volt with ~~ #6 wiring. 220/240 volt means two inverters and they may have to be big ones such as is available from Magnum Energy.

    Do you have a 24vdc solar motor controller picked out?

    You know things are slow when we play with a two year old post.

    bharadwaj is a new poster (yesterday). I will move to his own thread once he come back and gets used to the forum software.

    12 volt motors can be used on 100' wells though the volume is "kind of small". I would surmise that a 24 volt pump could work on a 200' well with similar volume. Seems like the wiring should be pretty large in either case.
