JPM,
I have left you an open invitation to “take your best shot”. We can now see (for you) what that amounts to:
• Vague notions of engineering and unsubstantiated personal opinions on technical subjects
• Generous display of your solar laurels
• References to people you know high solar places
• And unsolicited personal opinions which are little more than personal attacks.
When I pointed out your lack of comprehension of the discussion, you still failed to make even one cogent technical point that might have demonstrated some minimal level of understanding. It is apparently completely over your head. To remind you this was the subject:
My answer to these inquiries was concise, elegant, geometrical, and to the point.
Any fixed panel tilt angle from one set of coordinates can be transformed into another frame using Euler Angles. More importantly any optimality that the original panel orientation might have (pick your metrics or program) can be transformed to a new roof line orientation by a simple rotation about the panel normal.
In a simple example to demonstrate the principle, consider a shallow hip roof not aligned with North South, but rather in between cardinal directions. Assume further that the panel has a shallow tilt angle typically higher than the roof pitch (it is easier to visualize). You can easily transform the optimal fixed mounting orientation of the panel (assuming N-S) to another set of directions by simply rotating the panel about the (close to vertical) normal until the horizontal projection of the panel is in line with the selected roof line. While , this can be all calculated using direction cosines, I did not have to add that level of detail. The principle can be visualized and implemented by purely geometrical methods.
• You complained that direction cosines are too complex; only for someone that is not degreed and I’m starting to see that that seems to fit you.
• You complained that Euler angles do not take into account the great variety of solar considerations; you failed to recognize the fundamental fact that the problems of optimal positions and translation to other roof lines are analytically separable processes. It is a two-step solution that will accommodate any set of constraints or objectives because the second part, the translation to different roof lines, only need to know the optimal fixed panel orientation.
• You complained I made it too complex; you are the one that has over complicated the discussion and failed to see the simplifying principles that maintain optimality.
• You are the one that does not seem to understand any of what was posted; Even albert436 seems to get it.
You complain that I am a danger to the forum for spreading unsound advice; It is clear that you are the one without technical acumen and often exhibit a total failure to understand basic engineering. The key to understanding this fact is in the decisions you reach.
You have an overt tendency is to offer personal opinions and personal attacks much more than any technical concept. I guess It is all part of the package for someone so insecure that they must pontificate on topics that clearly go beyond their grasp, and attempt to demean other just to elevate themselves.
The offer is still open “take your best shot”, anything technical. Based on past performance, I’m not holding my breath.
