Yes, solar panels do have polarity. Polarity relates to the positive and negative terminals of the panel..
Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other..
The two primary terminals of a solar panel are the positive (+) and negative (-) leads. Generally, the positive side is connected to a busbar, which gathers the current from adjacent cells. [pdf]

When panels face the sun optimally and have the right tilt angle, they capture more sunlight, resulting in higher electricity generation..
When panels face the sun optimally and have the right tilt angle, they capture more sunlight, resulting in higher electricity generation..
An ideal angle for your solar panels will be equal or close to the latitude of where you are installing your solar panels. Therefore, a typical angle is between 30° and 45°..
Therefore, the ideal solar panel angle for your array would be about 34 degrees..
For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy. [pdf]
