Inexpensive Nexstar mounts

Does anybody know if the inexpensive Nexstar mounts for the 80mm, 114mm and the like can be aligned and uses during the daytime fpr solar observing? How well do these models track and do at goto?

Thanks

Here's my set up. The Tel Vue Sol-searcher is a must have, can have the sun in view in seconds.
