Changing Yingli Mounting

4:51 am:
I do not like the way that I mounted the Yingli solar panel on Box Van's roof. So, I am having the Yingli taken down.

When it's down, I'll attach [4] flat steel plates [1/8" thick x 1/2" wide x 3" long] to the bottom of the panel's aluminum frame. Then have the Yingli put back up on Box Van's roof and remounted.

The thing that I did not like about the first mounting, was that I used 1/4"  threaded rod to secure the panel. These threaded rods went thru the roof. Then thru Box Van's interior aluminum roof braces and had a hex nut on the bottom to hold the Yingli down. Wrong!

The new mounting will secure the solar panel with sheet metal screws thru the [4] flat steel plates and into Box Van's interior aluminum roof braces.




5:05 am:
Construction will begin next week instead of this week. An Arrow [brand] brad nailer was to be used for all of the construction. But when I went to use the Arrow nailer, it would not fire! So, I had to order a replacement from Amazon. That replacement is scheduled for next Monday delivery.

All of our construction will be pin and glue. This is the construction method used for building cabinets. I will be using pin and glue for all wood joining.



6:26 am:
I have been neglecting regular physical workouts lately. I don't much care for the 24-Hour Fitness in La Mesa. Maybe that's the reason for not working out. But I love the 24 Hour on Balboa. Why didn't I go there?

I am Blogging to you from Denny's. After leaving Denny's, I'll go to the 24 Hour on Balboa.

It's amazing to me how little food that I need in order to feel good. I was hungry this morning. That's why I went to Denny's. But I ate only about 30% of one of Denny's 55+ Senior Breakfasts!


12:28 pm:
I'm not really pushing myself to complete the Yingli solar rework. It may get today. Tomorrow would be OK too.

After my time at 24-Hour Fitness, I ate a little potato salad for lunch. Then painted the [4] steel plates with white Rust-Oleum.

The plates are outside while the paint is drying.



PS: It's really easy for me to do projects like the solar panel rework when my workshop is in the back of my living quarters! A little work here. A little work there!


11:56 pm:
I've just completed a major straightening of Box Van's stuff. This work resulted in discarding two of our plastic containers. 

Also, all the plastic containers that do not contain stuff that I need regularly are now in one place. I never need to look in those containers anymore when I am searching for something!

Our Rubbermaid ice chest is now contributing to my daily welfare. Refrigeration is a wonderful thing!

Good nite!

  1. So very interesting, George. I have been checking in with you more frequently than in the past. I love the updates, throughout the day!

    Just think, when complete, this will be your RV, created by you, how you want it done.

    That's pretty cool! Go, George, go. :-)

    1. Thank you, Kent! 😎

      One thing that I want done is lots of drawers!

      I really love that my experience as an apprentice cabinetmaker [1996-2000] will kick-in here to help with the construction!

  2. What specifically was wrong with the original mounting?

    1. Hi Phil,

      Firstly, I chose a complicated way to mount the Yingli. And that way left irregular drilled holes thru Box Van's aluminum roof that were almost impossible to seal after installation.

      The rework will put four tiny holes in the roof made by sheet metal screws which will be driven thru the sealant forming a very good seal.

    2. George, Will your sheet metal screw mounting of the solar panel withstand a potential 90 mph wind like when you're traveling 60 mph with a possible 30 mph head wind gust?

    3. Leo,

      The sheet metal screws that I am using were tested for pull-out and sheer strength. That test was conducted last week.

      The gages that were used in those tests were calibrated by the US Bureau of Weights and Measures who certifies stuff like this.

      The tests reported that solar panels the size of Yingli would withstand wind pressures just under mach 2 using the sheet metal screw that I intend to use!

    4. US Bureau of weight and measures that's brilliant

    I sure hope those sheet metal screws don't pull out when the 60mph highway wind gets under the solar panels and tugs at them like a wing. The guy behind you should hope so too.

    1. Joe,

      Some sheet metal screws are little tiny weeny things. And other sheet metal screws are BIG mothas!

      I shall use the BIG mothas! 🤣

    2. I doubt George cares much about those traveling behind him. If he did, he would not have continued to tow Scampy after the first time it came loose. I think George cares about George and no one else.

    3. Wow, Jim,

      Your comment is sooooo judgmental! Especially considering that you have never met me. And that you only know me thru my Blogging.

      You know something, Jim? You are just pulling my chain! Why would you do that?

      I stand corrected, assuming you're using #12 or larger hex-drive screws with lok-tite protection into the frame tubes and the gap between the roof and the panels is under about an inch.

    5. Joe,

      My friend Pete commented about using 3M Double Sided tape instead of screws.

      I am now going to use that tape!

      I know you're pulling my chain.

      Having said that, so e of the modern industrial tapes are remarkable ly strong if you have a large enough surface area to distribute the force. Not here though.

      Good try.

  4. Hi George . you need to make some sort of backing plate and thru bolt the solar mounts. simply screwing sheet metal screws thru that flimsy tin roof wont hold long. that tin roof will flex and bounce as you drive causeing the holes to egg out around the screws.

    1. Ray,

      The substantial sheet metal screws that I shall use go into Box Van's tubular roof support.

      What experience do you have to analyze a mechanical assembly as this solar panel tie down?

      I, on the other-hand, worked as a machinist for many years. And then was the general manager of a metal working company for several years. I installed my first solar electric system on my RV in 2003.

      All of my experience concludes that my plan for using sheet metal screws to tie down the Yingli is a good one!

    They're only trying to keep you for repeating the Solar panels incident that blew off on your Mexican trip ??

    1. Ed,

      Good point!

      Having many Readers looking over my shoulder and giving me advice is a HUGE benefit for me!

    2. It's only a benefit if you heed some of it

    3. Ed,

      In my opinion, what you are actually meaning in this comment of yours is:

      "It's only a benefit if you heed all of MY advice."

      Ed, I have used your advice many times. I do not "heed" your advice all the time, however!
