7.2 part I - PV Modules I

awesome video thanks for the upload

Interesting!!

Just came up. I'd say it can be very significant to have the wrong tilt.
Yesterday I tilted 20o for 50% more power.

Also installations with near panels cannot tilt as they would tend to shade, if lifting the upper panel. I would say there should be a minimum of three shifts in the tilt per year for optimal system yeild
