House Battery

9:07 am:
Last nite I went over to John's home in order to use his electric power. John leaves a heavy duty extension cord out in his driveway especially for me! 😎

Because of the weather, my Yingli 250-watt solar panel has not been producing enough to keep my house battery charged. That is the reason that I have purchased (2) additional solar panels of 200-watts each. This will give me 650 watts of solar capacity.

All of this solar power is only necessary during the depth of winter.


9:25 pm:
I have purchased an extension ladder in order to have access to Box Van's roof. I will not actually go myself on the roof. I will stand on the ladder and do what is necessary from there.

I bought this ladder from Amazon [Link]. The ladder is named Xtend & Climb 770P and is a telescoping device. Yesterday afternoon I went to give Xtend & Climb a try in order to get my new solar panels up on Box Van's roof.

Following the instructions and also from watching a YouTube video, I attempted to raise the ladder. I could not raise it! After many tries to raise the ladder, I finally was able to do it. But I had to change the instructions in order to get the ladder to raise for me.

Instead of raising the ladder by extending from the lower to upper rungs, I am able to extend the ladder by extending from the upper to lower rungs.



3:45 pm:
One of my 200-watt solar panels is now mounted on Box Van's roof. Wow! It was a tough thing for me to get it up there too!

I used the new ladder on one side of Box Van. And on the other side of Box Van used a rope which I attached to my travel case [See pic below].

The travel case acted as a counter-weight.

Counterweight.


250-watt panel [Rear], 200-watt panel [Front]. 


Note:
The new 200-watt panel is not yet part of Box Van's solar electric system because the required MC4 connector cables have not arrived.



8:24 pm:
I have returned to John's home in order to use his shore power again.

I want to get my two house batteries into a fully charged state.

    Did you consider a folding multi-task ladder like the Little Giant? Harbor Freight has an equivelent for about $90 when on sale. It stands a little under 5ft folded and opens to 17ft. I have one and it's great.

    1. Hi Joe,

      Looks good! But no, I did not consider this type of ladder.

      I am guessing that you feel that this is a better ladder than the one that I bought.

  4. I could see you saying lack of sunshine for a low batteries
    Have you measured the input of your solar panel and the output of your solar charger
    With your two batteries should be more than sufficient something is not right

    1. Ed,

      My Nova 12-volt DC refrigerator draws 35 watts when the compressor is running and it runs about 30% of the time on a 70℉ day.

      The Nova Kool fridge is my big power user.

    What's holding the new panel to the roof? I hope it's not just some small pieces of tape under the mounting tabs.

    1. Joe,

      Yes, it is. But that tape is the very special 3M VHB tape!

      Are you commenting that I am kidding?

    On large surfaces in a relatively clean and vibration-free environment, I'd agree. On the roof of an RV where it gets wet and dusty while the wind is lifting it like a wing, I can see that little patch of tape eventually working loose. It it comes off while you'Re tooling down the freeway at 70 mph, it could kill the person behind you or next to you, This is a noble experiment but I fear you're experimenting with fire.

    1. Joe,

      I am guessing that you may not have followed the link that I provided you in my reply above.

      3M VHB tape is a widely used product. Other RVers are using VHB tape for their solar panels.

    I'm very familiar with using these industrial-grade tapes properly. It mall comes down to contact area and the PSI the pulling force develops. I'm an engineer and have over 45 years experience developing products and equipment that employ various fastening technologies. These tapes are wonderful when consideration is given to the PSI of the pulling force and the environment. In your application, it appears that you have 4 pads about 1.5 sq.in. each, so the pulling force is applied over a very small area, making the PSI on each pad possibly quite high under highway wind conditions. Further, if just a tiny area of a pad peels up, water and dust will migrate under that area, destroying the adhesive bond in that area, As a result,the PSI on the remaining contact area then increases, allowing a little more peeling and a little more PSI on the pad. Eventually, that pad might pull completely off. Whether this eventually happens to you is a crap-shoot, but if that mount lets loose it could be catastrophic for someone behind or next to you.

    You could provide some remedy by increasing the contact area, perhaps by mounting an aluminum cross piece between the brackets and putting a long strip of tape on that.

    This is advisory. You obviously can do what you wish.

    1. Joe,

      I am going to continue to use 3M VHB tape to secure my solar panels.

  9. Just because some Jack-Ass on the internet "did it" is a horrible reason to temp fate.
    I know the consequence to you is minimal and you can go with the "well, the guy on the internet told me to do it" explanation to the family of the driver you killed.
    Why do you think that the Manufacture has mounting hardware to secure their panels? Call their Technical Support and ask if you can tape the panels to your truck's roof. They may choke laughing at what a lazy amateur you are.
    This reminds the reads of how you causally shrugged off Scampi coming unhitched and rolling down the road, TWICE!
    Go turn your driver's license back in to the DMV and get a full time care taker. You have horrible judgement.

      You are not very polite today.
