The Charts were very nicely done i liked the First 1 with all the seasons in different colors .I have only been playing in the Solar sand box for 6 months but that is exactly what i have recorded in my records and i have also taken shots of the sun & shadows about once a week. as well ,its nice to see a lay out that way ,nice and easy to grasp.
At 1:08 you said at the equinox, the angle of the sun is equal to your latitude. Rather, it’s equal to the 90 degree complement of your latitude. If your at the equator (0 degrees), the sun is at 90 degrees. If your at the North Pole (90 degrees), the sun’s angle is 0 degrees. If you are at 40 degrees latitude , the sun’s angle would be 50 degrees, and so forth.
I believe the angle from the horizon (North) to Polaris is equal to your latitude. The celestial equator ( 0 degree Declination) is 90 degrees from Polaris. The Celestial Equator is (90 degrees - Latitude) from the South Horizon. The sun (apparent) moves 23.5+/- degrees from the Celestial Equator.
Very interesting video and thanks for the downloadable charts which are very useful.It as made me a lot wiser as to thinking of installing solar panels.At my age I think I would be 120 years old before it was pay back time from the installation costs.
Thx. Great video. I have two questions pls: 1) Does your curve depict a tracking panel or a fixed one?, 2) in ballpark figure, how much more electricity in % does a tracking panel produce vs. a fixed one? Thx in advance...
Can a person use an Arduino $20.00 board to monitor your TED value and at some point rotate your tracker away from the sun to maintain your 0 watts input to the grid automatically? This might nail your 0 watts without the switches but this is too complicated for me! You are a smart guy!
Very informative video and soundtrack. Wherever you are in the States it looks great. I built a couple of panels 12 months ago with broken cells from solar 101. Unfortunately didn't seal them properly and condensation killed them - another project to revisit :-)
On the equinox, the sun is not at angle equal to your latitude. It is equal to the 90° complement of your altitude. For example if you are at the equator your latitude is 0°, but the sun is 90° over head. If you’re at the north pole your latitude is 90°, but the sun is it 0° above the horizon. I live at 42°, so on the equinox the sun is 48° above the horizon (at noontime). .
Good info! Could you send me the link for the graph of the power chart? I opened it once, but I can't seem to get it back. If you have a printable copy I'd appreciate it.
On the equinox it is the zenith angle that is your latitude NOT the altitude (ie angle from the horizon). Otherwise on the equinox the north pole would have the sun overhead!
If that's the case, isn't it always better to use a tracker and cut 2 or 3 panels from your system to pay for it? It looks like you get more per dollar with a tracker/panel system. Thanks for your reply :)
I was curious, how much power does a solar tracker use? So if you subtract that from the increased power output per day for a tracking panel compare to a non tracking panel, what is the amount of increased power production per day? And for the extra cost of a tracker, how many extra panels can you buy. So in the end will the cost per output be the same for both?
@Fearlessthinker Like u do! NO i have a fair idea were the sun is at midday and the angle to set panels but can,t quot line and verse with out looking it up on the web site with my home pined to show were i live,U got me, That,s why i thought that chart was very nice i can get a visual in my head as i think back to my pictures i have been taking. It seemed very real to me .
Solar sux! At only time during the day do you even have a chance at maximum power. The rest of the times you are only getting a fraction of the power. If you were to average the power over the entire day, it seems like it would only be about half of the peak power. That means if you have a 500W solar kit, you will be lucky to get 250W per hour, and then there are lots of other losses after that power is generated. Solar is the king of losses.
David, you are King of the Half Empty Cup. Solar radiation is free. The fact that a panel gets varying %effectiveness thru the day is part of system design calculation. Using those calculations, solar power is now pretty much equal to grid power in terms of cost/watt. What's your beef?

Good diagram! I never really noticed that the sun doesn't get very high in autumn until my panels were in shade! 😎👍❤️

What is total energy feel by any area according to solid angle and density and angular momentum of earth ?
Good contribution. Gets me wondering about machines to help with dynamic positioning of the solar panels

I think its been proven that it is cheaper to buy more panels than invest in a tracking system.
Very interesting and well done, thank you!
For comparison, I wonder how that curve would look like for the same solar with a tracking system. More rectangular, I guess?
Still the best!
Well done sir
I hope to have mine point directly at the sun at all times someday.

You can find something like this on the Avasva page. Full step-by-step instructions right on your desk.
Show the formula. How do u find azimuth and altitute angle?
Excellent
It seem a good presentation but I can hardly hear.
why does the sun go over south and not north??? can someone help pls, I have my finals tommorow XD
🙏🏼 #VOLTINU
Thank you!
could you have a louder voice maybe?
Good day and you..
@Fearlessthinker Also grasshopper has not studied as long as u Master.Please to Forgive my humble self
You need to make some changes. Check Avasva Solutions if you want to make it right.
@FearlessthinkerI I got That part. ;-)

but countering your idea, sunlight is the king of abundance
