You didn't measure actual power output. The 1.2 A was measured as short-circuit current. You assume it will still output that current when a 19.7 VDC load. You would need a load bank to measure power output under those conditions. My interest is a simple setup to verify power output of used panels I might buy.
Have you learned how to make that simple setup? Very interested in this as well.
@@trihumtrans1 There are even better solutions (e.g. an electronic load), but as a relatively-simple step up from what's being done here, you could have a second multimeter measuring at the same point, but still measuring voltage -- so, you see what the voltage drop is with that short-circuit current of 1.2A. Ideal, though, would be able to generate a curve of different voltages with different amp draws depending on different loads...
love the forest vibe audio
You don't measure current like that, the meter has to be in series with the load. You measured short-circuit the current, that's why you are only seeing an output of 23 watts.
I have a question, if someone can help me. Ive tested my panels, they test right for volts and amp. My panels are tilted properly for the area ilive. Its a bright sunny day, maybe a bit of haze in the sky. My panels are producing about 60-65% of it wattage, is that normal, or whatcould be wrong? Thanks to anyone who can help.
I have the same frustration. I have a 200 W panel that produces at best 140 W ?#@? I have never gotten higher readings. Couple things; the temperature may be decreasing the efficiency of the output; here in Texas, my panel gets exceeding hot on the surface and this decreases output. Also, I run about 40-ft of cable from the panel to the charge-control; maybe there's some drop since it is DC current. I dunno, but I'm only getting 70% - at best.
@@NUKE.2024ya, ive read up on heat, its been a hot summer here, will see what the fall winter will be like. Thanks
Guys it's normal it's just the efficiency of the solar panel, it depends on which type of panel did you buy and what's its efficiency is
Are you running panels in series or parallel? Or both? From what I understand you should be running them in both series and parallel to optimize their efficiency. Please correct me if I'm wrong.
@@mrtravistoole Not really, their connection depends on the voltage and current you are after, to maximize the efficiency you take other factors in consideration such as the tilt angle of the panels, cleaning them frequently, prevending any shading effects on them, etc...
WATT? ... WATT is not Volt X ShortCircuitAmpere, my friend. You're joking,I suppose.
So this is for 12v baterry?
nice video. are you a robot sir?
There's a new test kit, PVBuddy, an array cum panel non contact method.
so this monster size panel is producing 23 watts, this makes this a bad panel then, correct? supposed to be 100 watt. however, is this just cause no suns out watts out
bro calculating voltage in open circuit and calculating amp in fully close circuit 😂 mad😆
How does one know the polarity ( + / - ) of the XT adapter - which receptacle to insert the black-red probe ??
It should show negative on the multimeter.
Omg that voice….
bagong gising ata ang tai na to🤭🤣🤣🤣🤣
Are u a robot
