The difference between the summer months and the winter months angle of the sun is about 40°. Which ROUGHLY would mean that if your panels are tilted for optimal position based on noon of the summer solstice, at the winter solstice, the sunlight hitting the panel on a clear day is about 65% of that.<br /><br />Now then factor in what particulars and water vapor do to scatter sunlight...leehttps://www.blogger.com/profile/15723921072576401390noreply@blogger.comtag:blogger.com,1999:blog-22301740.post-37156086321105030522014-10-28T09:04:32.499-07:002014-10-28T09:04:32.499-07:00BTW, the issue with solar panels is not just about...BTW, the issue with solar panels is not just about how many hours per day the sun is out, but also something to do with the inverse square law of light combined with Lambert's cosine law: the greater the angle of the light off of the normal, the less light that actually hits the surface. By 60° off the normal, you're down 50%.leehttps://www.blogger.com/profile/15723921072576401390noreply@blogger.comtag:blogger.com,1999:blog-22301740.post-5505631407590617582014-10-24T13:50:12.019-07:002014-10-24T13:50:12.019-07:00Thanks, KT.

Of course, the flipside is that it will be out for quite a while in summer. <br /><br />We've actually been having a very fine Indian Summer (am I still allowed to say that?). But it's finally turning cold now.Jedi Master Ivyannoreply@blogger.com
