- 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?

I have found charts for the first two and the last one but not together.
Is this possible?

- Purpose of use
- Determine safe times for sun exposure using the rule of thumb that 45 degrees of elevation and above as unsafe.
- Comment/Request
- Even though I used the map search to find my location, the time zone was incorrectly shown as 9 hours (when it should have been 0 hours for GMT.)
