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. http://www.ntrei.com/scaffold.pdf Jim Duncan North Texas Renewable Energy Inc www.ntrei.com <http://www.ntrei.com/> NABCEP PV 031310-57 TECL-27398 nt...@1scom.net 817.917.0527 NABCEP Logo From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of August Goers Sent: Thursday, February 07, 2013 12:44 PM To: RE-wrenches Subject: [RE-wrenches] getting PV modules up to the roof 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, August 415.559.1525
