tilted south at latitude, tilted south at latitude.
So we go down and we click View Map to see what it looks like.
And this is the map that I showed you before and that I've already had run.
So you can create your own situation if we go back,
to create the second map that I mentioned.
We can look at July.
And July, rather than the annual average, which is the best month,
we can also look at some of the worst months, being say January, if we like.
And look at the single axis, not single axis,
but Two Axis Tracking Flat Plate.
Now let me just mention here, it's got two choices,
Two Axis Tracking Concentrator and Two Axis Tracking Flat Plate.
The reason there's a difference is because a concentrator will only reflect and
concentrate at the point you want it,
the direct radiation coming directly from the sun.
There's some diffuse radiation that's coming from the atmosphere
that gets scattered as the sun is coming through the atmosphere,
so there is less energy coming as direct radiation that
a concentrator can deal with, than if it's a flat plate.
So that's the reason there is the difference there.
But there's a difference between a concentrator and a flat plate.
Here we're talking about a flat plate, is what I've been talking about.
I created the high side that had all the red on it.
Using a Two Axis Tracking Flat Plate and looking at the one month of July,
and if I look click View Map, I come up with the map that
I showed you before where it's more uniform across the country.
Much higher the radiation intensity per unit area.
With the scale down here, shown,
goes from 10 to 14 out here in the West down to the tan,
which is about 7 to 8 over here all up and down in the East.
So there's some real advantages to being tracking and of course being in July.
We can look at that.
Let's just look real quickly at what it looks like for
annual average if we do a two axis tracking.
We go back and Return to menu and we go down.
And we look at annual average rather than just
July that we just looked at and we'll do the two axis tracking.
