Roof orientation plays a crucial role in determining the amount of sunlight your solar panels receive. In the Northern Hemisphere, south-facing roofs generally receive the most sunlight throughout the day, making them ideal for solar panel installations. East-facing roofs receive sunlight in the morning, while west-facing roofs receive sunlight in the afternoon. North-facing roofs receive the least amount of sunlight and are typically not suitable for solar panels. However, factors like shading from trees or nearby buildings can also influence the optimal placement. A shading analysis can help you identify any potential obstructions that could block sunlight and reduce energy production. In some cases, you may need to trim trees or adjust the placement of your panels to minimize shading. Even a small amount of shading can significantly impact the performance of your solar panels, so it's essential to carefully consider the surrounding environment. The art of solar panel placement involves not only maximizing sunlight exposure but also minimizing any potential sources of shading. By carefully assessing your roof orientation and shading conditions, you can ensure that your solar panels are positioned for optimal energy generation.
