How heavy is the solar scope? I have used an iOptron Smartstar G Cube successfully for solar observation for the past year. The iOptron Smartstar is Alt-Az but has full Goto tracking, and easily holds the sun in the FOV for hours, it's very accurate. I had it out at Lake Chaffey eariler this year and it was running for hours during the day for all to view the sun. The little iOptron mount has a payload capacity of about 11lbs (published) but you can do some mods on it to improve capacity (upgrading the Alt clutch disc, bracing the Alt gear housing, and bracing the tripod with a tray or hold down weight). If you can live without tracking then there are a number of AltAz mounts available, some with add on motor drives - like the Vixen Porta II, which (with Train and Track) can hold the sun for up to ten minutes in the FOV without tweaking the motor controls.
