What is the easiest/cheapest way to mount solar panels on my asphalt shingle roof? Thanks!

If your roof mount ever leaks, it will cost you far more than you saved.

I would prefer flashed standoffs holding rails.


 
I used the Iron Ridge flashfoot2 with their rails.
First time user could not be happier how easy it was.

Garage roof so very easy to check for leaks several driving rainstorms no issues.

I have been told about this brand/product, but ehri website seemed confusing with many different options and selection.

Did you install on a shingle roof? If so, could you list exactly the part numbers you used?
 
A couple times I mounted on a shake roof. I used lag screws into rafters at the eaves and ridge only.
I got one-piece standoffs and flashing, realized that two-piece (can be assembled through flashing) might have worked.

I thing the "professional" (i.e. high volume commodity) approach is lag screws through shingles into sheathing, gooped in the hope it will keep water out for a while.
Lifting asphalt shingle flap to put in some kind of flashed L-bracket might work.
I plan to install standoffs, and flashing together with shingles during a re-roof. Unirac rails with top clamps.

Yes, the Iron Ridge flashfeet look good:

Post #6 has a link to the mount that fastens to the roof trusses/joists.
Yes, it was an asphalt shingle roof about 10 years old Used XR100 rails and the misc. mounting hardware
You can get a complete bill of materials if you explore their design page.

Nice thing about those flashings, they are large enough to drill a test hole 1" from where it should be to verify truss locations and the flashing covers it up. I wanted the full wind load rating, so I made sure each lag bolt was in a truss and not just the flimsy decking.
