I don't tilt my panels anymore because I don't want to risk damage to my roof, or breaking my leg either.
It is now cheaper to get an additional panel than to tilt and worry about your time on the roof.
I can recall my first 90 watt system with controller, mounts, wiring, ect. for $750. Then upgrading in 96 with a 75 watt panel for $375 - only $5 per watt! Later in 99, I installed some 120 watt for $429. Now you can get 140W for $229. Much less expensive than the original prices, and wages have gone way up, so what would have taken a couple weeks pay can now be paid off in one day's work.
Good luck,
Fred.
