Will a solar panel generate more electricity facing the sun than not, or does it not matter?
Question:
Answer:
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.
When the panel points exactly at the sun, it generates the most electricity.
I would say that it generates more electricity facing the sun because it is facing the sun directly causing the rays of the sun to go straight into the solar panels.
It generates the most while facing the sun. At an angle, the panel will lose the light energy reflected off the panel. This is evident when you monitor the voltage a solar cell produces when exposing it to the sun at various angles.
Definitely, for optimum performances the solar panel will need to be facing the sun at a certain angle.
Anyway, if you plug a voltmeter to the output of your solar panel and you move it , you'll be able to monitor the variations.
