Hey Folkswe have a customer with a 24VDC fan for venting a green house
and we would like to be able to control speed on it instead of just
on/off...The fan draws 22 Amps at 24VDCAny suggestions on how to
regulate speed? The idea is to have the fan pull less than the 22
amps

i have the same thing in my greenhouse...
on a 24 volt dc system, i wired in a switch to change my two fans from parallel
(noisy and excessive air movement) to series. i run them in series 99% of the
time... plenty of air, less noise and long life on the brushes. (of course this
is only an op

Might it be easier to change the motor or is it just too large?

Just some quick thoughts.

The same PWM control used on charge controllers is also used on electric
vehicles for DC motors. We've done many different ones and different
voltages and sizes.
Something like this might work:

Greetings fellow Wrenches;
I have a customer that just purchased some Sunpower E20 -435 modules
somehow from Ebay, and wants me to design a backup power system for him.
This system would be battery based and not be grid tied. SO the
question is: has Sunpower put to rest the positive grounding
