I am contemplating fitting a solar panel tp provide lighting for my stables.
I looked up the recommended angle for mounting the panel and was a little surprised. Azimuth south makes sense but elevation equal to latitude puzzles me since the sun rarely reaches that elevation. Here at latitude 53N, my calculation is that even at the solstice the sun exceeds that elevation for only four hours. And that from August to May it never exceeds that elevation What am I miosunderstanding __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: [hidden email] SK23 7ND web: www.bings-knowle.co.uk/dcb <http://www.jb.man.ac.uk/~dcb> *Sent from my etch-a-sketch* <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist |

panel's angle which is important .Collapse of stout party __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: [hidden email] SK23 7ND web: www.bings-knowle.co.uk/dcb <http://www.jb.man.ac.uk/~dcb> *Sent from my etch-a-sketch* <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Tue, 15 Dec 2020 at 13:07, David C Brown <[hidden email]> wrote: > I am contemplating fitting a solar panel tp provide lighting for my > stables. > I looked up the recommended angle for mounting the panel and was a little > surprised. > > Azimuth south makes sense but elevation equal to latitude puzzles me since > the sun rarely reaches that elevation.

If you're looking at an off-grid application, generally you want to point
the panel such that it's most efficient on the shortest day of the year, and engineer for that. Note that this means latitude*minus* 15, or pointing at where the sun is on solar noon in about a week from now. If you engineer for that, then the rest of the year you're golden. Note that this means that if you are looking at a chart to maximize the total solar output over the year you should throw the chart out. These are only good for grid-tied applications, and will tell you to point at a different angle since you're optimizing for maximum year-long-total-output. There's a nice chart at https://offgridpermaculture.com/Off_Grid_Energy/Solar_Panel_Tilt_Angle_for_Maximum_Power_On_Grid_Off_Grid_Systems.html which shows the power production for each day of the year at various angles. You'll note that latitude-15 is the best for December, and the rest of the year is better than that.

Hmm - I think the labels may be wrong on the graph.
Why would it not be latitude PLUS 23.5 deg rather than minus 15 deg as you suggest for max power in winter? You want them MORE angled up to get the sun as it is closer to the horizon in winter, not more parallel to the ground. Wouldn't the panel perform best when it is perpendicular to the suns rays at the winter solstice?

Also depends on what time of the year you need the most power.

Sorry, missed, this reply two days ago..
The sun is lower on the horizon during the winter, so you want it pointed more at the horizon. But first a bit of orientation: The further north you go the higher the latitude. So 90* is at the horizon, i.e. vertical, and 0 degrees would be at the sky. So at 45 north yes, you'd want it at 45+15 or 60 degrees. AT 50 north, you'd want it at 45+15 or 65 degrees. An old resource, but still pretty valid is at nrel.gov/docs/legosti/old/5607.pdf , it's data for different sites, and will give you a multiplication factor which will tell you the average watts you will get out of a panel mounted at a given angle in each month. If the figure is like 3.0 for a month, you can take your panel wattage (say 300) and multiply it by this figure (3), and get the number of watt hours a day you'll get (900). Note that there are average/min/max figures and this data is from a range of years a while back.

Thanks. My confusion is mainly due to the fact,that, having worked
with radio telescopes for forty years, I think od pointing at the horizon as being elevation zero and pointing at the zenith as being elevation 90.

If you are some place that regularly has snow on the ground during the
winter, there is a significant amount of reflected light energy from the snow, so being even more vertical may be advantageous to collect more of the reflected energy. Also if there is significant snow, the more vertical the panel, the less snow that will stay on the panel and the sooner it will slide off. > -----Original Message----- > From: [hidden email] <[hidden email]> On Behalf Of > Forrest Christian (List Account) > Sent: December 17, 2020 5:24 AM > To: Microcontroller discussion list - Public. <[hidden email]> > Subject: Re: [OT] Solar p;anels > > Sorry, missed, this reply two days ago.. > > The sun is lower on the horizon during the winter, so you want it pointed > more at the horizon. > > But first a bit of orientation: The further north you go the higher the > latitude.
