SunCalc

I need to know compass degrees--to orient the line and point on the circle to points on a compass, or know how to get the app to display degrees.

Rotate and size a rectangular box, which represents a building, and then show the buildings shadow.

ie a flat line as the ground, mid point pointing to the sun showing its angle.

Use Google Earth as a map option

Building solar radiation observatory (of sorts). Would like method to know or calculate distance through earth (at night, of course) to clear view of Sun. That would be a cord from my location to (ideally) center of Sun. During local day, that...

What is the point of showing key directions of a natural event around a circle without a proper measuring tool? A compass would seem appropriate don't you think? A plus would be to extend the interactive sun direction so that it touches the...

To be able to run the slider as an automated sequence watching the sun track through the day.

Zoom should work from the selected point, not the visible center.

LAT/LNG and time zone values for the selected point would be helpful ... see: http://www.esrl.noaa.gov/gmd/grad/solcalc/

If there is a way to view the sun data from a json file, given the location and time, that would be great

it would be nice to be able to choose to show local time @ position of the pin, or local time of the browser, basically show times in UTC and then allow for correction for local time @ pin position or local time @ browser/user position

I wanted to install solar panels at the roof of my house. To maximize the sun light exposure to solar cell, I wanted to know how the sun moves over my house for the entire year

Right now the predicted sunrise/sunset times is inaccurate by season in NZ This appears as some hours out of synch for the time of year etc. I am presuming the suncalc is insensitive to daylight saving or is it a hemisphere issue Great App thank...

This would be an awesome add-on for plant growers, owners of solar panels, or... just for fun. So it would be nice to know how many lumens (approximately) a spot should be expected to be receiving at a given point of time in relation to the sun's...

have a check box list for different additions to the screen, i would like to see true and magnetic north being presented in the picture. many thanks and keep up the great work

From the center point I would benefit from seeing degrees from true and magnetic North.

Please include magnetic compass bearings for sunrise/set angles.

and also azimuth

I want to be able to set up a camera prior to sunrise so I want to know the heading to point the camera (degrees from north) so that when the sun comes up I'm at least close to getting the silhouette I want.

Hello Vladimir, First of all thank you for this really nice calculator and the js library of it you provide us. I noticed that you probably calculate with the wrong year; let me explain what I mean: The js Date() constructor uses as first...

Display of sunset direction in degrees and farthest seasonal swing for a lat/lon including the date for each. Great app.

You've got google earth with their elevation data. That influences the amount of shade some places get, but your app assumes the ground is flat. If you do have topology included, I can't find it. It's pretty awesome though.

Add altitude and azimuth for several key positions of the sun: sunrise, current position, transit, sunset. Also, would LOVE one for the Moon!! Being able to find out where to set your camera for a moonrise with an interesting foreground object!

Elevation could be simply place above the time line so you can see instantly see all possible elevation related to the time of the day. Useful and easy to implemented

Dear Sir, I am working on a Solar Electricity Generation Plant. I wannt a software for calculating the Yearly sun availibilty , its intensity... like in a fesibily report.. ' Can u help
