Well, the time of day I did this test was
between 11:30 AM and 12:45 PM
Eastern Standard Time (here in Connecticut.
The sun was in the southern part of the sky
at an azimuth of about 70 degrees.
The sky was a beautiful blue, but it was
occupied by maybe 30 percent clouds.
I do not have any voltage readings, yet –
and current would be very interesting, too.
I’ll have to get some meters hooked up so
I can look at current delivered and current
I can tell you this. A solar cell will deliver some
voltage from an overcast sky, but there must
be virtually no current available. I could
not power the C Crane under those conditions.
The weather has been cloudy here for days.
This was the first chance I had to try to power
the transmitter directly from sunlight. As long
as there is enough sun to cast shadows, the
I wanted to try to power the STL receiver,
but the sunlight is gone now.
I’ve got to get some meters in line for the
next test. (Whenever the sun comes back.)
As with all my projects, this is going to take
a fair amount of time.
But it is really fun.
