Finding the best angles for absorbing the benefit of natural light takes a lot more than just knowing East from West. I call it the 90% factor if you consider only that criteria when seeking a sunny disposition in your home. Clouds and general weather conditions aside we as humans can only do so much. Have you ever considered that Stonehenge might have been someones home and all they really wanted was to let some light in their life after eons of being a cave dweller. One small point of access and a dribble of light for a few moments each day has got to be depressing, let alone staving off wild animals with only a wooden club and a rock lashed to it. Talk about a daily grind!
The Summer Solstice is a day which has the most daylight to share. Consequently, the least amount received of those beneficial rays of the Sun happens in December just before Christmas on or about the 20th. This is the Winter Solstice and while its temperature doesn't deviate too much from our Summer the 3,100,000 mile difference in distance is plainly visible. Oddly, the Aphelion, or when we're closest to the Sun occurs in Winter and the Perihelion in Summer when we are the furthest away. My guess is that once you reach 90,000,000 miles giving or taking a couple of million doesn't amount to a hill of beans temperature wise. My amateur calculations show that 2017 will be a hot one relatively speaking.
If you haven't figured it out yet all of this cyphering to orient your home to maximize the welcome sunlight is better accomplished with NEW CONSTRUCTION than on existing homes. As our days and hours of light continue to shrink we all want to make the best of what we have while we have it. Darkness may be your preferred environment, as I'm certain you've all entered homes which were poorly lit both day & night. To lessen the brightness reverse the information here for that result.
Many factors are at work and the Earth's rotation and orbital path need to be taken under consideration also. Between all of our spinning and revolving we travel almost 600,000,000 miles a year. That's a pretty wild ride no matter how you piece it together. It can be out of this World!
