i have 2 X 3HP Falcon submersible pumps and want to run Solar On Grid. Could anyone help me how much watt solar panel, how much kwh inverter will require and other parts ?

Wow !
I'd start with switching out the pumps to a 3 phase motor, with a electronic controller/converter That should save some $ right there.

1/2 hp to 3 hp, 230 VAC single/three-phase input VFD
Are these well pumps or tank/pool pumps? Make sure they are not oversize, because that's what the
vendor had in stock when you were buying.
Then I'd look into Grid Tie solar, if the utility in your area allows it.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

Thanks a lot for quick detail help. It it viable to connect AC pump with 4Kv Solar Inverter to run 1 x 3hp motor ?

A single phase, 4KW inverter, will NEVER power a 3HP pump to full power. Using a 1:3 VFD as a soft start, you may get it to run, but the losses in a single phase 3hp motor, would require nearly 6KW to run it, and more to start it up. There are internal motor losses, Power Factor Losses and others you likely have not considered.
PV panels & inverter cannot run a motor directly, you need, as Naptown stated, batteries to stabilize the power.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

But if you cannot run the pump at low power or use batteries, then what little power the panels start to produce at 8am will be wasted until the sun is high enough to actually run the pump directly.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

Originally posted by green_regards View PostI have enclosed the details of Schneider Electric VFD and solar panel ratings for various motor capacities. However, they do not mention the need for batteries. Also, a few systems have been installed using these drives and panel wattages and apparently they are working fine (have not seen them personally. checked them on youtube.) Have I missed something? Or is there any difference in the actual performance V/S their claims?

I have enclosed the solar panel requirements as specified by Schneider, again as a pdf file.

Like I said, it will never work with a single phase pump motor. The link is for a VFD controller, and it can manage the available solar power, and run the 3 phase motor at reduced capacity.
Motor reduced = pumping reduced. The Pump Curves become all important.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
