[RE-wrenches] getting PV modules up to the roof

[Solarguy]

We started buying scaffolding in 2007 after renting it for our first 3
years. 

One man can lift one module 7 feet up to where one more man can grab then
stack it on a solid platform 4 deep on each end of the walkboards. 8 panels
stacked 8 feet off the ground in under 10 minutes. 

Step off the walkboard onto a 2nd story roof. 

Yes it's a significant investment and is bulky to transport but it makes
roof access way easier, provides a place to keep tools & equipment within
reach and is just plain easier to climb than ladders. And safer. 

Not to mention it's a great assembly platform for trackers.

Hi Wrenches,

 

I imagine that all of us working in rooftop PV have put some good hard
thought on the best way to get the modules up to the roof. There are various
lifts on the market, you can hoist them with ropes manually, or walk them up
a ladder (sling them over your back). I find that the majority of our
competition in the Bay Area walks panels up the ladder for residential
projects. What is your feeling about OSHA compliance of doing this?

 

Best,
