    There's also a Powerjack for increased energy needs...

    Tesla Powerpack is the company's utility-scale rechargeable battery, designed to store energy for off-grid and supplemental power systems, including large facilities and the electric grid. Like Powerwall, Tesla's battery for home and small business use, Powerpack is based on lithium ion battery technology.

    Interesting build for a cheap small scale system

    my third favorite is lithium iron phosphate batteries, the correct ones will last 4 times longer than lithium ion batteries, and they cost about the same amount.
    I have a set to run my home lighting, they are charged by solar. (12V system, 20AH)

    Here it is bit more x-treme:

    Shortest day during winter is about 6 hrs of sun
    Longest day summertime 18.5 hrs

    But its often overcast...

    If you live in a house or have your own land, you should be able to harvest a lot of power where you are at.

    Prices comming down on panels and systems.. Payback times are shortening... from the typical 10 yrs

    my system has one 100W panel, a row of AGM batteries, and a small charge controller.
    it is enough to run my lights, my shortwave transceiver, and charge my phones/tablets.
    I have a direct solar run music player that I setup, so I don't need batteries for it.
    almost forgot, I have a tiny refrigerated box I built that will run nicely from my solar power system.
    I could connect off the computer to it and run it, but usually do not as the inverter fan makes noise
    not sure if it will run my clothes washer or not, but kind of a moot point because it will not run my will pump.
    if I can get the well pump running on solar, I really don't have other needs for electricity.
    direct solar run well pump and gravity feed seem like the best solution (no batteries to wear out), but will have to wait to get 3K$ extra (I assume this will take years)

    suppose I could set up a system to get way more power, but no real point,
    electricity has been so pricy for so long, I just quit using most of it.

    yes. for a long time now.

    charging your handheld radio from solar is very handy. likely more handy than the tablet or phone.
    I can charge all my daily use handheld radios on my solar.
    my solar power setup came from me going on a radio contest once a year. (why I bothered getting it all in the first place)
    I use power pole connectors on everything and it all comes apart and packs up in my car easy.
    when I could, (after I was done renting in life), I just installed it at home.
    I also did a backpack version
    spacecase0.com: HF backpack radio

    your folding panel is likely way more handy than what I have

    I really like your HF/VHF/UHF backpack system. With that setup you could go outside and talk to other operators all over the world. And 33 pounds is about 15 kgs so thats also a very good workout if you hike a couple of miles from home.

    The only thing I would change, is to replace the heavy lead acid battery into a lighter more powerdense lithium type battery..

    I had few digital contacts with US stations on the westcoast,, But I cant make it to you guys on phone lol

    it has been a long time from when I posted that, I already replaced the lead acid battery with a lithium iron phosphate battery.
    unlike the "Musk Li-Ion battery pack", lithium iron phosphate batteries will not light on fire. (they also last 4 times longer at the same price as Li-ion)
    I also now have a portable low powered PSK31 modem NUE-PSK Digital Modem
    so I can do digital mobile as well

    lots of designing a solar power setup is getting rid of standby drain and getting higher efficiency.
    so many people don't bother with those 2 things. and it is why they end up having to spend way more money than they need to for the same result.

    I suppose this topic is about battery.
    I don't know much about battery.

    Well, study and learn. Then you can start up your own company in Malaysia and installing green power everywhere there.
    You got plenty sun so. Better place for solar is hard to find.. And a lot of panels are actually made in your country..

    You will be the CEO, some electricians and installers will do the tech and manual labour for u, lol

    for off grid home use
    I bet one of the best ones is the zinc bromine battery
    Zinc–bromine battery - Wikipedia
    they do have an issue of needing to be discharged,
    but that is super easy to deal with if you have 2 of them that are automatically set to trade off what is being used and what one is being charged.

    next best would be the nickel iron
    Nickel–iron battery - Wikipedia

    or at least as far as how I view the world

    Thanks, sounds like a good idea.
    I hardly see people using solar panels here.
