Just a little warning: during my tests, I lowered the input voltage and under 3.5V, the circuit doesn't cut but becomes crazy and the output (that was set to 15V with the pot.) jumps to 40V with no load. With a 2k resistor at the output, it only goes to 30V.
Of course, this is under the specified minimum voltage, but for solar applications, how can you guarantee that the input voltage will not be there?
So when it says "Module Suitable For Solar Panel" I'm suspicious. If you really want to use it like that, you could add a small circuit between the solar panels and the converter to cut it if the voltage drops under the minimum 3.8V or clamp the output with a zener (there's no voltage rating on the output capacitor so that kind of overvoltage could damage it if it is not designed to handle 40V)
Also the problem with that kind of circuit is that if you try to extract too much current from a solar cell, its voltage drops, but then the converter will try to get even more current to keep it's output and the input voltage drops even more... So you also have to add a circuit that limits the output current when the input voltage drops.
Conclusion: good circuit if you use it properly but not really appropriate for solar panels despite what it says in the title.
Works as specified if you stay in the limits.

Will bu used in the future with old PC-power-supplies for variable voltages.
I have tested it with a power supply and measured the output voltage. The input was 7.2 Volts. I have used output at voltages of more than 25 V down to 1.5 Volts.
The trimmer for the output voltage is extremely sensitive (10 turn potentiometer) so that the exact voltage can be set easily.
The input voltage should be 5 Volt or higher for stable output.

Q:
I used AA batteries of 11 volt. I connected two of these modules with the battery one is adjusted to 5v and another is adjusted to 12 v. If drain voltage from any one it works good,when i use both the voltage suddenly went high and damaged my electrical circuits. why?

And how did you set it, in paralel? You used to connect two circuits from one powersource, but the otputs are not isolated, so one pole is always connected from input to output, so you simply cant connect two outputs together.

Does this module provide constant current for driving high power LEDs?

I never measured it with an oscilloscope or anything like that but I've used these for basic led strip lights drawing 3A at 5v bucked from 12v and I also boosted 5v to 12v at 2A. There was no voltage dips at that point (there is an alright smoothing capacitor on the output). I wouldn't push the much farther than that to power high drain LEDs because they got very hot how I used them. Youd want a heatsink on the regulator or maybe even a fan. At that point your better off just using a more well suited power supply I reckon.

Q:
Ibought them in Nov 2019 and noticed A HUGE PROBLEM already mentioned by one buye. When the input voltage drops below 3.7V ITHE DEVICE GENERATES A HUGE VOLTAGE SPIKE of more than 50 V !!! This will likely DESTROY your equipment !

I've had the same problem! I disclamed about this phenonem to the manufacuror via BG about 2 years ago. THIS is 'Unforgivable' construction.FAULT. It seems that they haven't changed the constuction since then. SHAME ON YOU MANUFACTUROR (and a bit of shame on BG too, for NOT to correct this thing by informing the manuf.) THIS PHENOMEN WILL ABSOLUTELY DESTROY YOUR ELECTRONICS. Where does the liabelity lie? At BG or at the 'Manufacturor? A 'strange phenomen' accures with this unit: when you utterly decrase the 'Input' voltage to say < ~2,7V the unit 'suddenly' shuts of to 0V as it is supposed to do Hmm.... so there's a 'KILLER-ZONE' between ~3,3V down to; ~2,7V OMG.
