Because PV panels are able to capture more solar energy when they are pointed directly at the sun, installers may configure systems to optimize output by adjusting the orientation and tilt of a system, or by using mechanisms that track the sun as it traverses the sky. Notably, most roofs don't allow this facing. If it cannot be installed facing south or north, an east-west system is best. Though it reduces the total annual yield by approximately 10-15% compared to the ideal alignment, the east-west alignment has the advantage of use for people who have morning. In Southern California, where electricity rates keep climbing and the rules around solar have completely changed, this decision matters more than ever. You've probably noticed solar panels on rooftops around Los Angeles, Ventura, and Orange Counties. They also produce less electricity in the morning but more in the afternoon. One. Orientation Impact is Massive: The difference between optimal and poor solar panel placement can impact energy production by up to 30%, making proper positioning one of the most critical factors in maximizing your solar investment return.
