A solar PV system can generate energy even if placed in the shade. Although, the quantity of energy produced will be reduced. a minimum of 4 panels are installed at a time. Otherwise

In Which Direction Should Solar Panels Be Installed?

Some solar installations incorporate tracking systems that automatically adjust the panel angle throughout the day to follow the direction of the sun. Effect of Roof Slope. The slope of the roof on which solar panels are installed also plays a crucial role in energy production. The roof slope determines the angle at which the panels are inclined.

Can Solar Panels be Laid Flat on the Roof? (or Angled?)

Yes, you can install solar panels flat, but they will experience a degree of energy loss without the slightest inclination towards the sunlight. Although it certainly is advantageous to have a roof that is inclined in the sun''s direction, a flat surface will also do.
