Measuring the sun

Measuring the sun

As part of my ambition to get a solar electric system up and running I have been conducting some tests.

My interest is in the effect of the suns angle to the panel array and the relationship to voltage. While there are probably some models put there, I have not seen any and find that actual experience is much more convincing and reliable.

My observations will influence my decision to include tracking capabilities to my solar installation.

Notice the clever little rod below the panels whose shadow (or lack of) can be used to determine if it is pointed directly at the sun.
