Tech/Engineering - Construction / Civil Engineering / Solar energy | | Spanish term or phrase: proyección sobre el plano horizontal de la normal | This is an article about how to design buildings more efficiently by optimizing energy demand and photovoltaic energy generation. Actually, I need help with the phrase between the asterisks, but I will put the second part in another question since all of it does not fit in the question box. The problem sentence is the following:
El ángulo de azimut α define el ***ángulo entre la proyección sobre el plano horizontal de la normal a la superficie del módulo y el meridiano del lugar***, con valores entre -90° y 90° |
| | | the projection of the normal (to the module) onto the horizontal plane ... | Explanation:
...the angle between the projection of the normal to the module onto the horizontal plane and the meridian of the location
This is what the source text actually says, it seems to me. The only term whose meaning is not obvious to a lay person is "la normal", which means an imaginary line perpendicular to the surface of something, in this case the "módulo". This is explained here, in a different context, in the Wikipedia article on Snell's Law (on refraction):
"La línea entrecortada delimita la línea normal, la cual es la línea imaginaria perpendicular a la superficie."
http://es.wikipedia.org/wiki/Ley_de_Snell
The DRAE defines it thus: "Se dice de la perpendicular en el punto de contacto al plano o recta tangentes a una superficie o línea curvas"
http://buscon.rae.es/draeI/SrvltGUIBusUsual?TIPO_HTML=2&TIPO...
"Normal" is used in the same sense in English:
"The normal vector, often simply called the "normal," to a surface is a vector perpendicular to it."
http://mathworld.wolfram.com/NormalVector.html
So it is saying that the angle of azimuth is the angle between (1) the normal to the module projected onto the horizontal plane, and (2) the meridian of the place or location.

Sorry: I missed out "superficie"; I should have said "to the surface of the module". That's part of the other question, however.

A couple of examples to illustrate the use of these terms:
"Aspect/ orientation: the surface azimuth angle, the deviation of the projection of the normal to the plane in question on the equator plane from the local meridian"
http://www.appropedia.org/An_open_source_simulation_of_photo...
"and the azimuth angle, g, is the angle between the southward direction and the direction of the projection of the normal to the surface onto the horizontal plane"

"the angle between a projection onto a perpendicular reference plane formed by the module surface and the meridian of the location." (The reference plane is formed from that of the module surface and the meridian of the location).
