Solar panels will not work as efficiently in the shade as they do in full sunlight. This is because the performance of a solar panel is directly related to the amount of sunlight it receives. When a solar panel is partially or fully shaded, the amount of light that reaches the photovoltaic cells is reduced, resulting in a decrease in the amount of electricity that can be generated. In fact, even a small amount of shading can have a significant impact on the performance of a solar panel. When a portion of a solar panel is shaded, the voltage of that portion is reduced, causing the entire panel to operate at a lower voltage. This, in turn, reduces the overall efficiency of the panel and the amount of electricity it generates. For this reason, it is important to carefully consider the shading conditions of a solar panel system when designing and installing the panels. If you have trees or other structures that may cause shading, you may need to trim or remove them or adjust the orientation and tilt of the panels to ensure that they receive as much direct sunlight as possible.
