    Reading value from Solar Panel Cell, current peak concern

    @hevans1944 I am surprised it's actually water. I realize the rankine cycle one of the most efficient ways to make electricty (turbines) but I figured the sun wasn't "hot enough fast enough" to do like flash vaporizing or something. I recentlyheard about using molten salt I'm not sure if that's...

    Ha that's funny practicality over cost or what's the term. I did look up "omnidirectional panels" just for kicks interesting A hemisphere design that could also focus the light I don't know... interesting stuff.

    Haha probably not "Get down from there you lawsuit waiting to happen!" haha I could share the ledge with my friend possibly. I don't know, it's a cool project/got exposed to ADC/how to measure stuff/setting up the site. I would like it to continue but would suck if the data is not great because...

    Reading value from Solar Panel Cell, current peak concern

    Cold solder joints, I twisted them together... going point about measuring them together. Good tip on the angle, one problem is I'm in an apartment complex and I can't exactly position/place the panel as freely as I'd like to my roommate has a ledge on his window so he can actually get sun. It...

    Reading value from Solar Panel Cell, current peak concern

    I measured them all they're 330 Ohms (with a multimeter) Actually it occurred to me that my window has an overhang and also the sun passes across and not towards my panel (not sure how much of a difference that would make). Mostly though when the sun was most intense my panel was in a shadow...

    Reading value from Solar Panel Cell, current peak concern

    I don't understand it seems to be peaking at 0.18V it was higher than that yesterday but didn't surpass 0.4V it's almost noon, will see. Granted sun's path is going orthogonal to the panel's face.

    Reading value from Solar Panel Cell, current peak concern

    Yeap another cloudy day... Good ol' angle of insolation I think, isn't that neat I think the Earth is farthest from the sun during summer time, could be wrong. edit: guess it depends whose summer Yeah I'm waiting for a nice sunny day.

    Reading value from Solar Panel Cell, current peak concern

    Is this suggesting solar panels work better in winter or no? I think that site literally meant magnification even showed some graphic of rays going through the edges of a cloud. At any rate, today is another cloudy day :( I'd like to work out why it's only measuring what it's measuring with...

    Reading value from Solar Panel Cell, current peak concern

    Is that with regard to... man I thought I was safe about that but not even sure the spec sheet says 2.7V to 5.5V with "active current" of 320 micro amps Anyway yeah I'm looking forward to a sunny day as well, thanks for the help good to have sensible data at least the plain voltage one was kind...

    Reading value from Solar Panel Cell, current peak concern

    Sorry that was a typo meant 8 AM, this is with the 7 330ohm resistors in parallel I saw somewhere on a website that clouds can magnify sunlight/create a spike is that true? Something about edges of cumulonimbus clouds or something. I'm getting close to the chart part, I want to setup a...

    Reading value from Solar Panel Cell, current peak concern

    Today's a cloudy day but man, it's struggling... 8PM and it's only measuring approximately 0.01V, it is really cloudy like a rainy day.

    Reading value from Solar Panel Cell, current peak concern

    That's V = IR right? haha okay thanks I set it up/wired it. Will see what happens. Good point about the LED, I'm not even sure if I wired it right as the ADC was attached after the resistor instead of parallel/with (sorry if this is confusing I showed a wiring diagram in the previous post)

    Reading value from Solar Panel Cell, current peak concern

    Just to confirm, this is what I intend to do at this time regarding measuring "short-circuit current" with the 7 330ohm 1/4 watt resistors, will re-read what has been posted to make sure. Does this look right? I am a visual person, pictures help haha. Yeah I guess I'm still not 100% on the...

    Reading value from Solar Panel Cell, current peak concern

    Oh man... I just realized the sample was after the resistor, not sure if that matters, I will try that version (as well as reading about basic circuits) (see the attached diagram) The dotted line on the diagram on the right is what I'll try next. By "real light" I read somewhere about panels...

    Reading value from Solar Panel Cell, current peak concern

    The measure was probably dumb, I measured it with a multimeter being aware at least of the multimeter's max current limit but measuring it without load/not being exposed to real light probably means the measurement is useless. No resistor just direct output leads from solar cell. I believe it...

    Reading value from Solar Panel Cell, current peak concern

    Yeah sorry the diagram is pretty bad. The half circle on tbe ADC is the top, from my diagram the bottom left of the ADC is ch0 out of (0-7) Yeah initially it was in series with the load and the LED wasn't on, not sure if I was within spec with regard to nothing breaking. I have more unused...

    Reading value from Solar Panel Cell, current peak concern

    Yeah I'm not sure why I'm having a hard time understand this section of your response @ hevans1944 I did the initial described method because I figured the LED had a polarity so it should have the + end connected to the positive end of the photo cell output right? (as in my wiring drawing...

    Yeah I myself am behind in the webdev world, trying to catch up working with databases other than mysql, trying to learn a framework, but have to use it to learn it. With python I just started to use it but have been using PHP/JavaScript for a while. And with actual things I want to do it...

    Reading value from Solar Panel Cell, current peak concern

    It's a 1W LED though? Good to know about the 6 or 7 330ohm resistors, I do have 10 of them from the kit so I will try that. Unfortunately my public IP changed (damn DHCP) so it's one of the checks to my crappy url post and all the data stopped recording at 6 AM, after I fixed it though I see a...

    Reading value from Solar Panel Cell, current peak concern

    Well that was completely wrong about the four resistors in series to "increase wattage" Luckily my friend has a 1W LED... so just gotta figure out... this wasn't a trick question right? No... need to add a resistor to the LED for something. Panel at best can produce 4.8V * 0.1A (measured...
