I wish you will do a video on Solar Panels Brands i am seeking an reliable solar panel that will work for a long long time (30-60 years without warranty is wishful but it would be interesting to know what is the closest to that) I am also interested in mixed off the grid Power with 50% solar 50% air/wind power that will power an 500w-3000w for 120days-20days and if that would be more then $100000 manually/DIY built).
P.S. I am in Romania so i do not have access to that many options and also wildly different prices but if it can be done somewhere it must be a solution for me, also do you know any good Hiking Solar Panels with maybe an small Tesla battery pack, it needs to be light weight and foldable, but to also have enough power so you can fully charge your battery in a few hours, and that battery to power the night lights and maybe a laptop and phone charges for that night maybe?
hi will, this is one of my favorite solar videos you have done, i can understand some of it. also saw you doing a massage machine chair in the other vid lol The real thing is A LOT better and i do a good job with them like i said before, just let me know if you need one anytime. Hope you liked the postcard i sent you too. i havnt been doing any vids of guam, the beaches or jungle, ive been trying to get settled still. -chris f
Some time make a video about controlling insects in the RV ...
could I use this method to charge a NOCO GB150 with a solar panel?
Thanks for your great videos. I took at 12v car radiator fan I got from an auto salvage lot, and built a simple mount out of plywood to attach to my attic gable vent to pull hot air out of my attic. I put a 12v Grape Solar 100watt panel on the roof and it drives the fan directly. The sun comes up, the fan powers up - the more sun, the faster it goes, nighttime, no power - perfect. It's been running this way for over a year. All-in I paid just under $100 for the whole thing.
Best solar channel on UA-cam...
Will is not responsible when you fry your stuff.
The excitement in your voice is such a joy!
Your so cute lol
Done 5 years ago and this is still a huge amount of info for beginners, and as I have my training in electronics I still learn and love to tinker, This is awesome and valuable info!
info at 2:05 how a converter differs from a controller is GOLD ! thank you Will another excellent video
I kind of figured that sooner or later you would cross over into stuff I was doing in 2004. I was running around and camping in National Forests in the midwest with 2 marine panels and a Morningstar SunGuard charge controller. I actually wound up in Palo Alto for a while slapping the panels on a couple of roofs while there. Everything Will is saying about the merits of portable power are dead on. I'd be as careful as he is too. It isn't a good idea to charge camera batteries with hot leads like I did. But, one thing that worked well for me was jump starting my subcompact with a panel on an interstate once. DC to DC, so efficient :-)
I never thought to do this, could come in handy at some point, thanks for sharing....
You go, Will! Thanks for showing us this. Nice plan to help cool a hot attic-- on when you need it most, off automatically. Great ideas, thanks--
My Prius actually has this built in. I got the solar roof model and it just powers a fan when parked in the sun to cool the interior. Pretty cool.
*Willam,* You have such exceptional intellectual and creative powers.
You have extraordinary skills and so many other natural abilities.
Love you and your channel. Thank’s. Xoxo
Thank you Will for simplifying DC solar direct and for sharing links to your awesome recommended products. Can you please give a link and or info on the white double fan you used in the video? Love all you do ,thanks for taking the time to share .Ive been a fan since you werent feeling well and living in a van .Its heart warming that you turned your solar power hobby into a great success with your books .Much respect ,Love your house .
I use a mttp solar charge controller module .attached to a found solar panel that only produces 9v ....the modules are cheap on ebay , no battery just producing 5v which i use to charge all of my mobile devices ...its worked for the last month propped up at my window 👍👍
yes makes a lot sense...will be looking into this
You Are A Genius! I Like The Idea Of Solar Power Of A Laptop Since It Has A Battery Already Installed In It. Just Need The 24/12 converter And A 50 Watt Solar Panel And I'm Good To Go! Man What An Idea!
This is fun. Love your enthusiasm. 😊👍🏽
Another great vid by mr will you are the man dude thanks :)😁😁👍👍👍
Thx for showing me this, this could be very useful for a rocket power system. Again love the video, great work!
(To save weight on a battery)
Awesome! Can't wait for the experiment on heavy loads like a DC hot water element maybe?
I was considering that to do 5v out for charging a USB battery thingy to run a 5v .5a tiny fan all night. Lol. I figure it would double the amps coming out of the panel.
I was going to ask you about it but you posted this! Lol. You're great :)
here in Az we get stupid desert temps and trying to run an RV fridge was a problem- but installing 2 old style computer fans in the fridge vent with a small solar as the vent cover really helped- no switches, no converter just carefully selected solar panel-- just a thought
As long as I have been doing this stuff, you amaze me, I still learn from you. Are you in college or do you have a degree? I wish you were close to me, you would love my shop for building.
Finally. I’m new to solar and I want to make a solar pool heater. I want to go from the solar panel and go straight to the 12 v pump. This is the information I’ve been looking for because I was wondering about the voltage going to high and cooking my pump. Adding the converter will solve any issues. When the sun ☀️ is up the pool heater will be on.👍
Did you get your heater going? I am trying to get small 12v sump pumps to act as water jets to power a pool skimmer with a 40w12v panel using a wattage step down between them.

Not yet but still thinking about it. I’m a bit undecided on how to make the collector’s. My pump is a new 12 water pump for a Toyota Prius. It moves a lot of water , maybe to much. At the end of a sunny day, do you get the same BTU’s with a high flow rate vs a slow flow.
Hi will thanx for the double sweet videos, im very fortunate to have mark lee that owns 10 companies in china and 15 in japan, so i always look at your vids and do my own experiments, im from south afrika were the locals cant afford expensave croceries, one nice conversion i did was to rip out a 220 v compressor out a old fridge and replace with a 12v/24v compressor. Got 55 hours on a gell 200 ah bat, only batt no solar panel connected, at 12 v uses 5 amps a hour, on 24v 2,5 amps.
I like it when you say "our stuff" your adorable
I like it, when I see young people like you, come up with smart ideas..Great Job.. Thanks
Smart stuff there. Simple sweet it awesome.
That would be good for cooling a system in a box in a vehicle. While your are charging your vehicle solar system you could be moderating the temperature in the vehicle solar system enclosure. A nice small panel in the space remaining, on the roof. Cool idea.
Thanks for showing your setup. I have done this on my 48v solar panels to 12v. Now I want to install my variable output voltage boost converter to charge any battery configuration. I want to charge my Ebike batteries off this system.
Your welcome. It was my discovery I can run inverter in the rain without a battery. Key is 24volt panels and 12 volt inverters. Using step down DC DC converter
You know your stuff dude, quite incredible. You should be teaching in trade school . Cheers.
Cool. I like your videos. Keep them coming.
Do yourself a 2019 favor and lay your reciepts flat and organize them into month by month envelopes. Although it takes time, I also put at the top the topic of the receipt. I also make sure I buy "road and vehicle" items on a separate receipt from food, personal items, etc. Sometimes it upsets those behind me to buy in multiple batches. Oh well, it also helps to organize your purchases when loading into your vehicle. The digital notes for the purchase can be more clearly marked, too. The only problem I have had at wally-world is to find multiple receipts to show to the "exit greeter".
I used this method to charge my drone batteries while camping without needing to lug a heavy battery around. I’m not sure how small a panel I can get away with though. It works fine with 100w panel. I’d like to get that down to about 25w for weight and size. I’m sure there is some math that would tell me the minimum size I can get away with.
Your video’s & site are just such life savers. If I want to use two panels do I still have to run them in parallel tho?
Putting an ultra capacitor bank on the output will improve the performance tremendously and will help start inductive loads.
Interesting! Thank you for sharing this knowledge with us.
I have a question and that is, can one power a 220volt 3000 or 4000watts solar output setting without a battery?
Thank you!
Can this Direct solar config be connected to a device that can switch from solar to battery automatically?
Cool stuff - simple but effective.
Another great job Will. I have a Piper Super Cub. What’s the smallest yet best system I could get into my airplane to take out to my remote fishing camps in Alaska ?
You are amazing!!!!
Thank you
God bless you, thanks for your dedication and humble knowledge
*sounds great*
This is great! May I know how to run a 180watt pump with this setup? what adjustments can I do to run it in case it doesn't work?
Great video!
Hi does this regulator regulate the output wattage also ie if I was using a 12v 30watt fan with 150watt panel would it regulate the amount of watts need not to burn the fan motor out?
Bro. For a nerd type explanation you great I view you stuff all the time ,keep it up bro
Direct solar is well worth playing with, I built a circuit which charged a one-farad Electrolytic Capacitor from a small solar panel and then dumps its load into a water pump to pump pulses of water uphill.
I ordered a 1 Farad for the same configuration. How well has it worked?
excellent post.
Hey will dude great video---will a 18v solar panel work with the 24v to 12v convertor...i was wandering what voltage panel your using---many thanks bud
great video!
I've wondered about this a long time. Would it work if I had 4 300 watt panels on roof and then run wires to wear they are needed? DC means very thick wires if it is long cable, DC doesn't like to run long distances in small wires... could over heat and fire also if wires aren't thick enough to handle the push
Is there a reason why you recommend the 80w over the 2 40w controller?
I need a 50w controller and not sure what to get.
Also batteries. Are the Vemax that much better than Universal?
thank you!!!
gotta try this.
Very good sir successfull for small waat
"It´s not THAT dangerous" aaaah I love it :D But anyways, very inspiring. I will for sure be looking more into this :)
good work Will o/
Interesting , thanks ... Portable laptop charger without a battery . Great for off grid and camping
Thank you for your videos. This is exactly what I want. No battery, just an opportunity to charge my laptop and phone with solar. But there is a huge list of resources and not the specific ones that you show on this video... the converter, the cables... even the reader. For just one 100 watt panel. Those 3 objects. If you can, I would appreciate it.
And why the XT60? If my computer has a regular connector to plug on the wall...
Hi , Wow what a great content! This system would be perfect to run a solar powered waterpump 12v 50W? I only need it to run during the daytime.
I'd like to go off the reservation here and recommend two books for you that have nothing whatsoever to do with anything in your videos. However having recently come across your channel and watched many of your videos I get a sense you might like reading these two books as you seem to be a curious person of varied interests. Although I do realize that gamers/techno guys are accustomed to something a bit more frenzied than the sedate practice of reading books of introspection/philosophical themes. Nevertheless, I have a sense that after reading these two books, you will be glad you did. Both books can be obtained for free from the local library. The first book is: Zen in the Art of Archery. The second recommendation is: Zen and the Art of Motorcycle Maintanence. I hope you read this post, and it peaks your interest.. 😎
Will check them out :D thanks Tom
I am very interested in powering big fan directly from my 100 w solar panel. where can i buy the small converter that you used?? thank you.
Wonder if a super small battery (like one out of a power tool) would be worth adding to take care of surge loads
Brilliant
I got a question u think a can buy a 300 watts can I plug theme up to an inverter and plug it to my house receptical and help me with the bill? Or I have to have battery’s ?
Have you tried connecting an APC UPS in to this set up....would be able to have the battery and the converter possible in one without needing to buy a separate battery and converter.
Thanks for this video; I feel so dumb! My small solar panel puts out 24V 1.12A & I was confused when it wouldn't run a small light bulb (not led) directly. As soon as I connected the light, the voltage would drop and nothing happened (no light). This was inconceivable to me because in my mind this panel is putting out a constant 24v and even with only 1 amp, the bulb should have produced some light when connected directly to the panel output.
Hello ... can we make a cut off also which gives power output only when the desired voltage is available from solar panel and if it goes below the reqd voltage it cuts off the supply to the appliance??
how would you set it up to charge things like 10- 20k battery banks? would you want to put an inverter in the middle?
I love your videos but and I trying to work this video out. I looked at your web site connection and I am then back to your video. I am confused about something. How do you plug in the lab top or fan without an inverter? that was not on your list but on your video you said you had a modified inverter. I didn't see it on the list. I know I am new but I am confused. can you explain the step that seems to be missing? Thank you
i have a 300 watt inverter, would i still need the 24v to 12v converter if i dont use battery? or can the inverter be connected directly to panel without converter? i have 100w solar panel.
thanks.
Will, since I don't know which lines on my solar panel are positive and negative, what would happen if I just plug in one of the lines at a time to see if it registers anything? Thank you.
I’ve got 4 D8 size 12 batteries to replace my current old ones for my cabin’s solar system to replace the 4 6 volt wired in parallel as two 12 volt batteries these d8 a are bigger and newer too they should work well
Interesting, would this work with a larger panel and micro-inverter to run 120v ac straight for quick and dirty power ?
Ty sir
wild i thought laptop chargers took AC and converted them into DC. here you're connecting DC at the source and it still works.
I saw your IG story post of the exploding converter capacitors. Just watch this video and this would be a perfect immediate solution to my charging problem for laptop and other devices. So what was the problem with the converter’s exploding capacitors. Would appreciate explanation before I go and invest in this system.
Oh that was my fault. Over voltage situation with solar array. That's all. Not over current.
Have you seen the spherical solar panel, what are your thoughts.
What wattage and voltage is the solar panel in that video? Just wondering
You can connect a fan or a pump directly to a panel, given that the fan can handle the max output of the panel. Fans and pumps can handle varying loads, they just go faster or slow down. However, electronics are different. This is playing with fire.
Why not use 12 volt solar panels instead of 24 volt panels and eliminate the need for the 24 volt to 12 volt converter? And, instead of using a converter, use a buck voltage regulator (available on Amazon) wired to the positive and negative wires of your 12 volt solar panel to prevent voltage fluctuation above 12 or 14 volts. For example, some 12 volt, 100 watt solar panels purportedly can produce as high as 17.5 volts instead of 12 volts. This voltage fluctuation would probably shorten the lifespan or eventually damage a device such as a 12 volt, direct current fan motor or a 12 volt water pump. Please reply to express your thoughts about this comment. Thank you so much for your informative, resourceful videos.
Did you plug the laptop adapter or you were using just the charger jack pin
You can buy solar stuff at hobby stores? Do you have any examples? Like a Michael's or Hobby Lobby? I've been trying to find cables and controllers locally, and having a hard time...
nice, im done watching
How is your move? I remember you left SF and rented a space in San Diego wasn’t it? Are you teaching? You’d be great at a trade school instructor
I’ll Try my black dc converter, from my e quad.
I use car electric radiator fans they work great and move allot of air in a window, junk yards have tons of them
Hi I need help here. My laptop charger says: Output 20v 2amp=40w. How 12DC output in that converter can changer the laptop? In this example you can only charge 12V laptop.. right? Please advise. Thanks in advance.
Can you explain if the DC-DC converter must be isolated. It's difficult to identify if a converter is isolated.
Will, did you happen to notice what Vpanel was under the various loads?
Does an MPPT controller borrow some volts from the battery to provided consistent voltage out as the solar voltage fluctuates?
What is the wattage of the solar panel you're using in this particular video
I have a 50w solar panel on my car roof, powering a 12 volt cooling fan in the window, Florida hot sun. I tried without a converter and battery setup. Solar panel puts out 21 volts. Saw how to use a (buck converter) to step down to 12 volts for the fan. worked perfectly until I noticed My door locks were going all wonky on my 2015 Rav4. some radio interference????? worked perfectly except for that. Now my cheap solar converter battery settup keeps dropping the solar connection. it may be damaged.?? I put an adjustable thermostat in line to turn on off. Buck converter was perfect and simple except for the door lock interference.
I have a 100W panel and i am hoping to run a 40W fountain pump with it. But I guess I'll need sine wave in the output to make it work. How can i do this without a battery? Thank you
I sometimes run a 12 volt jacobs water pump directly* from a solar panel.
I have a 340 watt solar panel what size step down do I need. To step down to 12v
Can the portable mini fridge/freezer with 110 ac work on this?
This might be exactly what I am looking for. Thinking of buying a bunch of cheap 50 dollar 250 watt solar panels to power an AC during the day, but I don't want to waste money on a battery. Might try something like this out while running the AC at max during the day to save me a few hundred dollars during the summer. Would also be great for charging my phone and laptop without using utilities.(Approaching 50 cents per kilowatt hour in California)
