I have a 300W panel and is around 25kg, any idea on how to lift the panel safely and efficiently?

Thanks.

    I've just slide them along an extension ladder in front of me, If you are uncomfortable with that you could beg, borrow/rent scaffolding. It might surprise you, if you live at all rural, how many people have scaffolding. After I broke down and purchased some I had a couple people say they wish they had know. They could have lent me some.

    If you are talking multiple stories it might be worth asking at a rental place for a shingle lift, I would worry about them on a narrow lift, but I suspect you could devise some method to stabilize.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    Hire young people!  When I need the help there are always young people who will lift batteries. The H series solar panels are too big for one person so I avoid them. I also never go on a roof including my own. Arrays are best on the ground if you can.

    And as Photowhit said scaffolding or a backhoe.

    My installer brought all the rails and panels in a horse trailer.  We backed it up right next to my solar shed roof, loaded the panels to the top of the trailer and then on to the roof.  Made a great work platform.

    Like Dave said, I used young people to get my 12 300 watt panels up on a 9 foot high ground mount rack.

    My wife and I have a great system worked out for us; we are both 60 plus, off grid, remote and rural.  No young people close by at all. We use our backhoe with forklifts mounted on the front loader.  We clamp a piece of 3/4 inch plywood to the forklift arms and load the solar panels on the plywood flat.  i never do more than three panels at a time to play it safe.  It is so easy to raise up the loader with panels.  Sometimes I have used 2 x 4's to bridge a gap if there is one and then just slide the panel to where you need it.  The backhoe is a Case 580 Construction King so we can raise the loader pretty high.  We do this for roofing material too.  So if you have access to a backhoe might want to give this a try.  We always go slow and easy and never rush.  If the wind is blowing, we do it another day.

    Being rural, and fifty-somethings ourselves (aside from there being no young people available); I stood at the top of the extension ladder upon our single-story roof while my wife tilted the panels up to the ladder at the base, then she lifted the panel from the bottom while I bend over (holding onto the ladder of course) and grabbed the top of the panel and lifted it onto the roof. Being an off-grid system, we only had to do 5 of these (though BIG panels!). Once you're done, take two Aleve, a shower, drink a beer, and go to bed !

    I'm 58. Just carried four 75 pound panels over 50 yards then hoisted them unto the roof. Had a glass of cold water and a game of computer Monopoly in celebration. Takes about 18 minutes to win on the computer. Used to take 4 1/2 minutes with a high speed controller on a 1989 Sega set. What happened to technology?
