It is worth noting that seasonal variations may require adjustments to the tilt angle to maintain optimal performance.

To calculate the optimal tilt angle, you can use the following formula:

Tilt angle = Latitude ± (Seasonal angle × Adjustment factor)

For example, if your latitude is 35 degrees and the seasonal angle is 23.5 degrees (summer solstice tilt), and the adjustment factor is 0.8 (to reduce the tilt for winter), the calculation would be:

Tilt angle = 35 ± (23.5 × 0.8) = 35 ± 18.8 = 16.2 to 53.8 degrees.

By ensuring optimal placement and orientation, you can maximize the amount of sunlight your solar panels receive and, subsequently, their efficiency.
