What is the general best angle to point your solar panels horizontally for
best power output daily? This is with no tracking and a fixed position.
I figure about where the sun is at 2:00 PM but this is only in the winter.
Does this vary from season to season.
Are there charts or calculations posted somewhere online?
How much difference will tracking make?
What is a good tracking system source?
Are there cheaper ways to set up tracking systems?

Pointing at the sun at noon.
Yes it varies with the seasons and the angle will depend on you latitude.
Have a look at www.susdesign.com
Depends on the tracker. 0 to 30 or 40% when the tracker works. Trackers
also increase the number of things that can go wrong. i.e. moving parts.
I spend a lot of time with these problems. Because of this I am not keen
on their use.
Suggest you talk to Duane Johnson. One of the few here who would know.

Wrong again. Pointing slightly below noon elevation makes more daily energy,
with more ground reflection and a higher average incidence angle cosine.
