From Duffie/Beckman, Seinfeld/Pandis, etc. 1-line, very accurate.

What's the application? Efficient calculation of solar noon? We already have too many ways to calculation solar position, so I'm reluctant to add more unless there's a good use case for them.

We have used it in the past, so I have to continue to support those calculations. Apples to apples.

It's literally a one liner, so not sure what the concern is. I think of pvlib as not just a tool box but also a single source of truth for PV formulas. Having this 1-liner completes the solar position calculation. Any IE coming across a random equation will need to vet it, whereas if the analysis uses pvlib, then the vetting has already been done. This saves time and money.

Now that I've looked at your updated #276 I think I understand what you're proposing. You want the equivalent of def solar_zenith_analytical(latitude, hour_angle, declination): for azimuth?

Yes, thx. I'll probably submit a PR early next week 😀
