We were curious about direction and panel angle of observed larger solar
panel in the Albuquerque, NM area.
First we ventured to Belen, NM, then toward Mountainair, NM

The bottom signal light was red but very dim. So dim,
in fact, that it may have been the sun reflecting off the red
As soon as the train passed, the bottom red light went out

Dangerous photography. Trains came off the track just
to west of Rio Puerco and entering Wild Horse mesa within the past several
years.Train signals, in the past, have been powered
Wde have recently notice that some BNSF train signal
appear turned off when no train is within visible distance.
|Here's an FAA solar panel located on Tierra Grande.
We used the
Harbor Freight angle finder
to measure about 45o
facing directly south.
|We returned to Belen, traveled up I25 to Los Lunas, then west to
the Rio Puerco and on to the Laguna reservation to see the Burlington Northern
Santa Fe solar/wind signal facility.
Here's looking to the
No lights on.
Here's looking to the west.
Maybe the facility has intelligence so that it only turns on lights
when a train is approaching from either direction? Or maybe it doesn't
Note the small size of the wind turbine. A similar wind turbine
was removed from a Bernalillo, NM simliar faciltity. It was replaced by a solar
panel seen in

We measured panel
angle on this installation on return to Albuquerque.
angle is 50o facing directly south, too.
We returned to Albuquerque and proceeded to the PNM solar array at
PNM experimental solar array.
We are trying to get technical information about it. No
success so far.
We previously thought the array was facing SE. I25 is
going NE at this point.
We measured with a Garmin portable GPS. It is
facing due south.
The angle of the panels measures about
Internet searches indicate that 60o is about
Measuring power, not voltage, out of our Harbor Freight solar
panel with 50 ohm load while varying the panel angle measured with our Harbor
Freight angle finder should give a good idea of optimal panel angle around
10.694 * 114, 000 = 1219116 BTU
1219116 / 316.1 = 3856.74
