Solar Panel Tilt Angle Calculator for your location

Okay, I just want to show a couple online calculators that I found that are pretty handy. I’m wanting to find out exactly what angles my panel should be set up for different times of the year, so they did some searching came across as one site it’s basically time trying to sell a book.

Your solar electricity handbook dot-com, but they do have some online calculators here that are pretty handy. They have three listed. Let’s just go to the first one here, the solar angle, calculator. Now what they let you do is to select your country.

Select. Your state my case Minnesota and select your city and it’ll calculate out the angles for different months of the year, showing the optimum angle of 22 degrees or my winter, setting 45 or spring and fall and 68 for the summer setting.

So that’s, basically what I was looking for, but I also then went and looked at the other online calculator it’s called the irradiance table. Similar thing pick my state and city, and what’s interesting about this? Is it brings up a table of how much kilowatt per meter per day? I would get with the Sun just hitting a horizontal surface and it has enlisted the average per day for each of the months, and obviously in June, which is the Sun is highest in.

The sky gives me more than the shortest day of the year, which is in December, but it also then lets you select different surfaces vertical optimal adjusts to the year and it changes the values of the table here.

So we go from a horizontal orientation to a vertical and you can see how the numbers change I’ll do optimum and do it just through the year now, if I put those three table values of those three types into a spreadsheet, it looks Like this, for my location, if I had, if I just looked at the kilowatt hour per meter per day per square meter per day for the whole year, it came out.

Forty four point: seven, if I had was looking just from a vertical orientation, it’s. Thirty seven point: two: if I had to adjust it just in my latitude, which was forty-five degrees or so comes out to this, and if I adjusted it on a monthly basis, they send that prior online calculator.

It would basically be my best case. So if I take the best case as a hundred percent, I can tell how much I’m, losing if I just set it at my latitude and leave it there. It’s, only a six percent loss which isn’t too bad.

But if I had panels at vertical which a lot of people do for like a hot air heater, they just mounted on the side of their house. There’s, really a loss of 32 % overhead, you put it in adjusted every month and actually 26 % loss.

If you had just had it set at your angle of your latitude and never adjusted it and then a horizontal surface, you’re, still 20 % down from where you would, if you adjusted it on a monthly basis. So clearly, the vertical orientation, at least at my latitude of 45 degrees, is suffering quite a loss there, so that’s, quite a big trade-off, but anyway, that’s.

Some interesting stuff that I didn’t really know, is available and be kind of helpful going down the road here. You
