Schuco used to sell a collector strap kit for solar thermal collectors but it was designed more for hoisting. We just installed a 30 collector system with it (not Schuco collectors though!) a few weeks ago.</span></p>

How about this?: A heavy-duty canvas bag for carrying PV modules, with backpack straps and D-rings in the corners? With a module pack bag, installers could climb a ladder with both hands while the module is securely on their back, Or it could also provide an easy way to tie on a rope and haul them up, or secure them on a sloped roof before installation. How many installers would be interested in something like that?? How much would you be willing to pay for it? </p>

<span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">It is not possible to maintain three points of contact at all times while carrying a module up a ladder. It is my understanding that if three-point contact is not possible at all times, then a personal fall arrest system is required. This is not called out specifically in <a href="http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10839" target="_blank">Subpart X</a>, but if an injury or fatality were to result from carrying modules up a ladder I think it would be difficult to avoid getting fined or sued.</span></p>

The only real issue is upfront cost, but this is cheap when compared to the long term cost of a workman’s comp claim.</span></p>

<p class="MsoNormal" style><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">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?</span></p>
