Open your mind a little, Wayne, and let the vaccuum out.


Why would anyone other than a quack want to think of parachutes when
mounting PV modules? Do you imagine that your wisdumb includes
aerodynamics? Of course you do!

But for sane people it's much easier to simply look at how all the
other normals mount their modules, as I encouraged you to do five
years ago by including links to about a dozen different photos of
closely-spaced modules, including these,


in order to rebut your asinine assertion that 4" spacing is "industry
standard". Why didn't you do yourself a favor and accept reality,
rather than being the incorrigible Johnny Appleseed of ignorance?

Pics of LED module and assembly in lamp.

That is not correct. From a photograph it cannot be told whether the sun was
out or it was in pitch black. many moonlight films are done in full sun with
compensating filters and camera settings.

These spot lights could be 500 watt halogens in full sunlight, single candle
power lamps in pitch darkness or 100 watt halogens at dusk, when most
nighttime photography takes place.

Yes, exposure can be set but can't really add more light than there
is. You will notice that the lamps themselves are blown out. Still the
photo is a fair representation.

Hmm, you sound just like wayne, call me a liar because you can't
accept the fact that correctly used LED can actually be very

Faux moon light on film is so easy to spot.

This picture was taken at around 11pm on a moonless night. The lamp in
the centre has 8 modules of 4 LEDs(luxans) each. The lamps on the left
and right have 6 modules each. I have 12 such lamps right around the
house. The trick is the white glass covers glass covers. Far more
effective than plastic covers for spreading the light. All the leds
actually point straight down.

No halogens, no daylight tricks, not shot at dusk. Give me a day or so
and I will post pictures of the modules and their mounting. They will
be at the same link.

he answer was in response to;

"I like it but it wouldn't be much good here as we experience 120km
winds on odd days from December to June, most years."

This is a significant wind loading. Correct spacing reduces the wind
loading by allowing some of the wind, that otherwise would cause
pressure on the panels, to pass through the obstruction. Still, it
comes as no surprise that you can't understand this, you understand so
little about design to begin with.
