Hi Luke: I can see why you wrote back giving your own websites as they are far superior to the site I mentioned. One difference that was immediately apparent is that your site works for ANY latitude and longitude, whereas one must pick a specific location from a list of locations with the site I mentioned. I haven't had time to study all that your site does in detail yet and there are some things that I don't understand; but I can see that the information would be of considerable value to dialists.
Thanks for your site info, John Carmichael >Hi John, > > If you are interested in site specific solar data try using my Solar >Calculator, URL below.
