This panel can put out close to 100 watts kzbin.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

[@adrianmoone6737]

GREAT VIDEO! can you show us how to change a pre-made outdoor solar security light? maybe how to make them turn on & off when we WANT instead of being motion detected? and maybe add a ?? dial if possible? to turn them up brighter or down for lower lighting? Then finally my biggest question! Is there any way to use these solar power lights for an alternative purpose? by maybe taking OUT the light, probably double up the batteries? and add a USB charger? I have 8 brand new ones, and I've already separated 3. Placed the solar on my outside & the light on my inside for motion detected lighting inside, but really they're brighter than I need. They stay going 3 days now so far with overcast! Free lighting! Yay!! (free solar phone charging would be AWSOME!

[@energycrafts8206]

Nice but you did not show the 10k resistor on schematic or where to solder. I assume this is the base current controlling resistor?

[@xlines]

EnergyCrafts the 10k resistor is more likely for the base of the transistor.

[@anoopanand7619]

Is possible to connect 6 volt DC LED?

Is the transistor working as some sort of current regulation there, or is the LED straight up getting the full battery voltage? If the second thing is the case, use a 3.3v regulator (if it‘s a linear one, it can still waste up to 800mW with a 3W LED but the LED will get a constant current).

[@samwallin9694]

its working as a switch it turns off the leds while the solar pannel is providing voltage which charges the batterys, but when the pannels are not producing voltage the leds turn on and use the battery voltage

@@samwallin9694 I know, it‘s a PNP type transistor. I just don‘t know if it has a internal resistance, because it‘s the only thing between the LED (2.6 to 3.3V) to the battery (2.6 to 4.2V).

[@ALEFILES]

@@samwallin9694 How does the current flow from batteries to the 1W Led (+) lead at night? The PNP transistor turns ON when it is night? If it is, the 2SA1019 transistor doesn't drive much current, just 0.05A, and the 1W LED needs at least 0.300 A... Greetings from Argentina!

[@sshutupurface8345]

i use 1k resistor with 18650 so the current is 4.2 milliamps and the led emits 0.017 watts good as night light lasts 55 days + permanently on

[@emre-uc1zh]

Does the value of the resistor depend on the current drawn by the connected load? Does the life of the battery depend on the resistance? What is the maximum current drawn by the load in this circuit?

[@ALEFILES]

The maximum current _DEPENDS_ of the maximum current the transistor can drive...If you use a small transistor, don't expect to connect a BIG led light, because you will burn the transistor...I suggest to use a BD140, TIP42C or similar, BUT REMEMBER: anything transistor you use MUST be PNP, otherwise the light won't turn on by night... It will be better If you use a MOSFET P-CHANNEL instead a bipolar transistor (e.g. IRF9640)... Greetings from Argentina!❤

[@christophergalero505]

What is functioning of resistor...

[@ekas9081]

If a larger LED will be installed, around 5 watts, do the transistors need to be replaced? If replaced, what type of transistor is appropriate?

These transistors commonly are rated for 300-600mA. A 5W LED could draw 1.5A at 3V. So just look for one that has such current capabilities and is PNP. Also, don‘t connect the LED straight up to the TP4056s output and use a buck regulator instead.

[@wessiez]

Goodday. What a simpel and great solution for this application. Is there a way to make the LED go on when it is a bit more dark? Mine is going on very soon...

[@mati211p]

How did you set current? I can't see any limitations? How much power did you get without resistor? Does it still work well without any resistors?

[@generalawareness101]

There is a lot wrong with this circuit, and you spotted one of the issues. The other issue is that there were no diodes used to prevent backflow energy. Normally 1 or 2 Schottky diodes are used to prevent that in 1 or two places in the circuit. The thing is you don't actually have to have a way to set the current in this setup since the 18650's are 3.7v nominal (but can go up to 4.2v) while the 1w led wants about 3.5v. Personally, for longevity of the LED, I would use an XL4056E right before the LED and set the current there so no matter what voltage hits it the current is what is driving it (which is what we want).

@@generalawareness101, i also thought about the LEDs getting a too high voltage. Even a 3.3V linear regulator possibly would do a good job here while still being more efficient. I don‘t know if the TP4056 already acts as a reverse current protection.

[@generalawareness101]

@ It does not and why a diode has to be inserted.

[@phitrow]

Out battery - 4,2v. LED in 3,3-3,4v. Need resistor for stabilisation carrent LED...?

[@FargothPL]

There's no need. You're losing some voltage across the transistor. I recreated a similar project (I found where I made a mistake when I previously use his scheme) and the voltage on the diode was 3.17V (so for white LED is ok), while the battery voltage was 4.1V

[@phitrow]

@@FargothPL ok

[@miteshdhanani]

On of switch is to be connected then

[@azmilulum3280]

Sorry, where is the Resistor located

[@arazmamedzade8110]

Collector max Current: -0.15 A for A1015 transistor and current of 1W LED is: 1W/3,3V= 0.3A. We have to add resistor(may be 10-12 Ohm) between collector and anode pins. It"ll be save LED"s life (and battery, too).

[@ronaldd.1355]

Why do you need a resistor? in my calculations it is not needed. The batteries when full charged 'll be: 4.20, the LED is about 3.3v, so you have to reduce: 0.9v, so (0.9v / 300ma) = 3OHMS. Not 10000, Am I right?

[@arazmamedzade8110]

@@ronaldd.1355 Dear Ronald, there is such a thing as "instantaneous current value", which affects the moment the load is turned on. This current exceeds the rated current by 5-6 times. In order for the LED (load) to not burn during switching on, we take a resistor 3-4 times more. In all other respects - of course you are right.

[@zainal851209]

What's the resistor for?

[@samwallin9694]

it was not used when i made this i used a 20 ohm resistor inline with the negative side of the led and that drops down the voltage as i was worried about burn out

[@wenzuken22]

can u teach me the wiring for the transistor its not clear

[@HeroCP7]

This is a pnp transistor. Shouldn't the base be connected to the negative of the solar panel? Wouldn't connecting the base to the opposite polarity be causing a short? It should honestly still work since electrons move from the negative to the positive terminal so it'll eventually reach the base but still i can't help but think it is causing a short somewhere.

[@ALEFILES]

Not at all. The base is connected to the right pin (+), because when the sun lights the panel, the +V of the panel _BLOCKS_ the PNP transistor, and _when the night comes,_ the voltage of the panel fall to zero, activating the transistor, and driving current from battery to the Led across the collector... Understood? Greetings from Argentina!❤

[@jonnymorillo1484]

Your 2x 1watt 6 volts solar panel are verry weak to charge 2x 2000mAh lithium battery. Cuz your 2 panel can only produce 0.333 amps of current, not much. (P/E or V=I) you do the math. And the TP 4056 will ignore it. Cuz TP4056 have a minimum accepting current of 37% battery capacity. So if you have 2x 2000mAh battery, you need 0.740amps of current from the panel to charge your battery. It means u need 5watts 6volts solar panel that can produce 0.833 amps of current enough to charge those 2x 2000mAh battery. But overall, i love the video. You work clean.

I tried with 3 such small solar panels in parallel but the TP4056 ciruit never got any reasonable charge even in a single 18650 cell. When I plugged in a USB Charger into the TP4056 board it charge but even with this stable Current supply it took more then 2 hours from 4.1 Volt to 4.2 Volt. I think the TP4056 boards are unable to manage the erratic power supply from the solar cells.

The solar panels charge the batteries during the day, at night the light uses the batteries. If using a usb cable to charge the batteries the solar panels are pretty much just used to turn the light off during the day.
