Solar elevation angle (for a day) Calculator

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

Input negative degree for west longtitude and south latitude.
If your local time is on Daylight Saving time, select 'ON' from DST mode.

    Comment/Request
    It would great to have a change option on the start stop time with just as many points but not only 24 hours but 12, 6, 3, & 1 so Solar noon time can be precise. Solar noon can be as much as 16 minutes off from noon but your chart peaks at 12:00 noon. Must fix

    also have execute button removed and the enter key after changing a number would execute.

    Purpose of use
    I wanted to calculate the percentage of the major components of the sun's radiation that would get reflected by a reflective shade cloth deployed vertically 1000 feet via baloons and spaced one every mile in an east west deployment in a given area and then calculate how much local cooling effect this could create, possibly making a local air rotation.

    Purpose of use
    Calculate correct position of solar panel. Excellent chart, thank you!
    Comment/Request
    I suggest you add explanation of "time zone" since it does not adjust automatically based on longitude. For example USA Eastern time zone normal designation is "GMT-5:00" but you want me to enter "19" ... How is the user supposed to know this?

    Purpose of use
    Looking for hours of sunlight available to a tree given the sunrise, sunset and angle.
    I have found charts for the first two and the last one but not together.
    Is this possible?
