- This video shows the 3 common methods that used to operate a DC load directly to solar panel without using battery and charge controller. Different method has its advantage and disadvantage. DC direct application is the cheapest method of Solar PV System without the need of expensive battery and charge controller. For more information, you can check it out at my blog post.

Excellent video! Really enjoyed that. Thank you.
This was really good teaching.. Subscribed..thanks
really helpful and informational.. thanks
Bro you done a great job 👏
This was great! Thanks for sharing.
You just made my day. Thanks.
Thanks! Can you please show what connectors you use from pump to the solar panel?
Hi thx for this vid !
I'm planning to use a small solar regulator and i should a car usb charger to charge 5v backup battery, what do u suggest please?
Very informative information Sir, can I use the control motor module for charging lithium batter? because it very convenient to adjust the voltage
Thanks!
good video thanks
Interesting explanation! Cheers from Australia ❤subbed and liked👍👍👍
wow.thanks
thanks for your tuttorıal vıdeos. greatıng from turkey.
Where can I find connectors compatible with the RockPals portable solar panel and pump wires
very cool!
Simple question. I want a mobile charging option without battery involved. I have a 60w portable panel and 10 amp mppt controller. Can I just connect the controller to a car cigarette socket and use the usb ports? Will the current be stabilized by the controller and car charger, and would the controller be damaged by not being connected to a battery?
Can I use a PWM motor speed controller and an amp / watt meter to solar power a peltier device without a battery?
This is great video. One question on disadvantages of "direct connection to load" approach at time 1:43. How would it be lowest efficiency or load operating under-powered. I'm thinking it's the other way, can you please clarify?
The efficeincy of the solar panel is reduced because the load will pull the voltage of the panel to way below it's maximum power point unless the load is small in comparison the to panel's output - in which case the panel's voltage may go high enough to damage the equipment connected to it (I burned out a fan this way!).
@3:00 what is that usb device for mesure?!? From where to buy it? "Keyweisi"?
Hi man, does it work without battery?!? Meaning inputing into "blue" standard controller both "panel" and "battery" spliting cables from the panel
Hi nice video. What method would you suggest to power a trolling motor of 12V 36A(max). The solar panel i am planning on getting is 18V isc 2A. should i connect it directly or is there a better way to not lose power and ofc with no battery. Will the speed controller setup work on this? planning to power my inflatable kayak.
Hi, since your panel is way smaller compared to your motor, I suggest you to use battery instead. The solar panel can slowly charge your battery when not in use.
Very interesting @Solarduino, I connected a DC pump direct. The pump will even disconnect when there is a cloud and voltage is too low. But it reconnects too early. Is there a system that can delay the reconnect until there is full sun again?
Hi, for this requirement, normally a micro controller is needed such as Arduino. The concept may be using Arduino and sense the irradiance, upon the irradiance reached a threshold / level, it then turn on the switch. However, this will cause alot of other components and wiring involved. If want everything to be simple, direct connection is the choice. Hope it explains.
nice
Wow. more Content please. Sending My support :d
Have you ever seen a problem like I have? Hook a 50 watt panel to a Bgears 70 computer fan up
to a solar heater and the fan only runs when I stand in front of the panel. All the connections
are tight. I hooked the red to red and black to black wires. It has a yellow wire for ground
but I haven't grounded it. If you have and ideas please let me know. Thank you.
I ground the motor and it is working. Thank you.
For type 3
Is it safe to operate devices in higher voltage than rated?
Can I place a buck converter before pwm input to regulate the voltage so that I will not over volt the device?
When you say we cannot oversize the panel meaning the Current or the watt rating?
Example 550w panel 17amps
Can only be used for less than 550w devices or less than 17amp devices?
Hi, for non electronics like motor you do not need to step down due to the reason voltage will auto drop when there is operation current. Cannot oversized the panel means by means of both wattage and current compare to your load as the pwm don't regulate power like cc buck converter. I have not tried adding converter before the PWM; It might work. Hope it explains.
Hi. Can combine it to the house db? Sharing power to the house
Hi, yes you can, but have to connect through an on-grid inverter that can synchronise with your utility grid. There is a type of mini on grid inverter which you can connect few panels to it and directly connected to house electrical network via wall socket/plug. It is a lot safer than connecting to DB. Kindly take note on grid pv system may be illegal for some countries if install by yourself or may need a permit..
Hi brother can i ask a question why isc of the solar panel must be lower than the load thank you
Because the ISC being lower than the limit of the load protects that equipment from being damaged by too much power input
How about the volt of the solar panel if it is more than the load does it not damaged the load?
Hi. good video. Can you teach me the design connection of solar pump. Pump size 60watts. Thankyou in advance
the current of the panel must be lessthan or equal to the load? am i correct? or morethan?
Hi, is your water pump DC rated? what is the technical specs of your water pump?
Helo, how can I use 1 panel for 2 motor load? Can I just parallel the wiring after DC-DC converter?
Hi, if you use only 1 converter, then can just parallel output (dc output set to the exact voltage rating of motor).
@@solarduino1374 Thankyou for your reply! And can I also use PWM after the converter parallel output? So the parallel output from converter connected to 2 PWMs and I can control both motor with these PWMs?
@@AlfiSeptandhi Did you get this to work? I have a 12v fan and 12v pump to connect to a 100w solar panel. They work fine connect alone to the panel. but not when connected to the PWM speed controller.
Can this be used to change an EV such as the Chevy Bolt?
Hi, EV requires manufacturer's charge converter which most probably requires AC power source. Do not direct charge a lithium ion batteries without going thru the proper charge converters or might have fire and safety risk. Hope it explains.
@@solarduino1374 Thank you, I think you just saved my EV 😬
@@solarduino1374 What if the EV has DC fast charging?
The music bro.
What is the power of your solar ?
Hi, the larger one is 30W and 2 identical panels are 18W each
Sound is not clear
U don't use buck converter in video
U can use solar charge controller without battery... U agree?
Bloody piano music 😱
Do you feel comfortable to design a system to charge an electric car without battery and with no connection to the grid ?
If yes, feel free to contact me. I am interested in your services. Thank you
