Sure, if you have about 2 acres of solar panels...
A 10hp motor *will not* run directly from solar panels. It will be an AC motor, so you will also need a battery bank and inverter.
10hp = 7.46kW
A *big* solar panel will produce roughly 100W (12V) in bright sunshine. You can do the maths from there.

Absolutely! See the forum below, and look in the section titled "solar water pumping." Surprisingly, many, but not all, AC motors will run off DC. For example, a portable drill generally will run off DC, even if it's made to plug into the wall. The typical large solar panel (2.5 x 5 feet) puts out perhaps 22 volts at 5 amps under good sun, and you'd need 4 of them to run your drill. The lower voltage is because the motor has less impedance at DC. The manufacturer won't guarantee that this scheme will work of course, and in fact, no one will, myself included. You're taking the risk, yourself. Google "run AC motor off DC" for more details. If all you're trying to do is a demonstration, see if you can find a computer case fan, and connect that straight to your panel.

Its very easy to find a 10HP dc motor to run directly off solar panels. Go to any of the motor manufacturers. GE, Siemens, ABB, Marathon, Beldor, Weg etc etc etc.
Finding the solar panels may be tough.

Yes there are DC motors which run directly off Solar power.
10 hp is apprx. 10 * 746 = 7460 Watts
Solar panels have a peak wattage of about 15 W /sqfoot
so for 7460 watts you will need 7460 / 15 = 497 sq ft of solar panels, pretty expensive.
Just search for Solar DC motors on google you will get lots of links.

It depends a great deal on what you're doing with the motor.
A place for DC motors.

Note that DC motor horsepower is nothing like gas engine horsepower. The large motor, rated at 20-28 hp... there are two of those motors in this drag racer

a Mazda RX-7 which does 11.03 in the quarter mile. Yes, seconds :)

You will not be able to carry the panels as they will be too large (see other answerers' responses).
The trick is to store the energy in a battery of sorts over time and then release it more quickly than it is gathered. Since metal or lithium-based batteries produce pollution when created and dumped, the ultimate alternative is a battery that stores energy in the form of compressed air as used for power in the Air Car (IE http://www.theaircar.com)
497 square feet (to get the power) * 1/8 (8 hours per day) = 62 square feet, which should not be too mind bogglingly expensive...it will produce 10 horsepower for up to 1 hour (IE from those 8 hours of charging) that way with true zero emissions.

Now the first question is, why do you need a 10 h.p. motor?
Is it for the torque, r.p.m.s why 10?
Don't forget, electric motors are just like any other and to get the most from the least you can also run it through a gearbox.

to answer your question it will be almost impossible solar panels are not very powerful at all it would take hundreds of solar panels and even then the power would never be continuos
