<div class="moz-cite-prefix">Several types of lifts are available at
rental yards. We've used a hand crank type air conditioner lift
to move 8 modules up at a time. For anything over 10 modules, its
really a good idea to use something besides a man on a ladder,
especially with today's larger modules. <br>

I see your point. I was questioning the ladder method
because walking modules up the ladder seems to be the
standard for roofs 2 stories or higher. I thought maybe some
folks had a different interpretation. I'm particularly
interested in seeing what Solar City is doing these days.</span></p>

I like the big tote bag/backpack idea. I believe it's been
discussed on the wrenches list before so you might want to
do a quick search. 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>

It is my understanding that if three-point contact
