Heck ya BigBill,
When I started this solar journey 4 years ago there was not much information out there. I had limited resources as well. So, before I threw huge numbers of dollars at this I decided to ease into it as best I could.
I purchased 9 panels. Hey, here is some solar power to get my batteries some juice. It was about 2,500 watts. I had no idea how many watts I would get in a day. Now I know you get about 4 x watts max in a day. 4 x 2500 = 10k. More in the summer from longer days and more direct sunlight and panels aimed more for summer exposure profile. I need a BUNCH of extra power in the summer to run AC all night. I added 15 more panels to bring my total PV up to about 25kwh. I just added 9 more (extra powerful) panels and now I have about 44kwh PV. These numbers are averages. I get more and less seasonally. Maybe 30kwh winter and 50kwh summer. I don't have many power issues in the winter except when it sometimes gets cloudy for weeks at a time.
Since my panels are skewed in different directions and in different locations, I have a longer sun exposure in a day. This flattens and extends my charging cycle, longer charging means shorter discharging. Solar panels are more efficient when cooler, it gets hotter on a roof than a ground mount. I didn't ever want to get on my roof for any reason. Roofs/shingles cannot be serviced when solar panels are in the way. Roof mounting increases opportunity for leaks.
For those reasons I spent the extra money on the ground mounts.
To answer the question:
My original wooden mounts 45 deg, improved wooden mounts 15 deg, what I did to seasonally adjust them, blocks. Now the real deal ground mounts that are 15 degrees. I have about 11kw of PV. When you examine the installation engineering. The more you incline your panel the less wind you can withstand. These numbers change fast.
Since I need max power in the summer, I configure my system mostly for summer.
Hope this helps in some way friend!
