Does the angle of incident sunlight to a solar cell impact
When the angle of incidence of light to a pv cell is less than 90 degrees, the effective area is smaller, producing less power output. By effective area i mean looking at a piece of paper head-on vs looking at it at a shallow angle- the latter makes the paper appear to have less area because of the angle to our eyes.

6 FAQs about [Can explain solar cells from different angles]
What is the angle of incidence of a solar panel?
Angle of Incidence, θ: This is the angle between the line that points to the sun and the angle that points straight out of a PV panel (also called the line that is normal to the surface of the panel). This is the most important angle. Solar panels are most efficient when pointing at the sun, so engineers want to minimize this angle at all times.
How to change the light incidence angle of a solar cell?
The test needs to change the light incidence angle of the solar cell, and the light from the solar simulator shines vertically on the solar cell from the bottom up, so it is not easy to change the angle, so the light incidence angle can be adjusted by changing the tilt angle of the solar cell.
