PV Gap

Geraldine Said:

Will a solar panel generate more electricity facing the sun than not, or does it not matter?

We Answered:

Abolutely the panel will generate the most energy when pointed directly toward the sun. There is a slight drop off with only a few degrees of error. If you are not loading the panel near capacity, it may not make much difference to you. But if you want to get every drop out of the panel, it is worth keeping them clean and constantly adjusted.

The incident light on the panel will be reduced by the cosine of the angle of the light source to the panel.

I lived for several years on a boat that used solar panels as the primary electrical power source. When that is your primary energy source, you learn to get the most from it.
