- Purpose of use
- Determine sun angle at different times of day throughout the year to optimise orientation and elevation of solar photovoltaic panels on a multi-facet roof.

- Purpose of use
- Determine sun azimuth through the day when measuring track and field event long throws or horizontal jumps. We use surveyors total stations for precise distance and avoid shooting up sun. Expected sun are for the day is important in positioning the instrument for proper view down sun.

- Purpose of use
- Determine shadows on a landscape planting plan

- Purpose of use
- CELESTIAL NAVIGATION ASTRONOMICAL DEVICE
- 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?
[8] 2019/03/19 15:59 Male / 60 years old level or over / Self-employed people / Very /
- Purpose of use
- Solving geometry problem
[9] 2019/03/16 02:34 Male / 60 years old level or over / A retired person / Useful /
- Purpose of use
- Correlating sun elevation with PV production figures related to panel orientations.
