Solar elevation angle (for a year) Calculator

Calculates a table of changes in the solar elevation and azimuth angles for a year and draws the chart.

Input negative degree for west longtitude and south latitude.
Daylight Saving time is not taken into consideration.

Purpose of use
Attempting to to determine for how many hours/day at any given time of year the sun will be at or greater than 30 degrees altitude for a specific location
While this data is interesting, it isn''t precisely what I was looking for. Does anyone know hoe I can better find the information I am looking for?

Purpose of use
Trying to understand relationship of equinoxes and solstices to places within the tropics where the sun''s altitude should reach (and exceed) 90deg
I don''t seem to be able to discover any days of the year where the sun''s altitude is 90deg for my place of observation in St.Helena, South Atlantic Ocean (15.9deg South). Can this be right?
from Keisan
The maximum value of the sun's altitude is 90deg. (Sun's Altitude <= 90deg)
The sun's altitude takes almost 90deg in St.Helena in November 2018.

Purpose of use
Determine best angle for a passive solar "awning".
I assume the azimuth angle is the location in the sky at noon.
[9]  2017/12/13 03:37   Male / 50 years old level / An engineer / A little /
Purpose of use
Calculate solar elevation angle at noon, to find best window overhang for summer shade and for winter sunlight.
Please provide a chart of what the number is for each time zone. I think Pacific is number 8, but few would know that. Actually Pacific may be number 9, since it gave a higher angle at 9 than at 8. I''ll check 10 also. A small diagram indicating what is meant by elevation and azimuth would help also.

Otherwise, good calculator. Better than getting out the calculator and doing the trigonometry by hand. :)
