South-facing solar panels are the best direction for maximum energy production in North America, generating up to 30% more electricity than other orientations. However, factors such as roof slope and proximity to the equator may have some homeowners considering other directions (including north). So. . Mixed-orientation solar panel systems, where panels face different directions on the same string, offer unique advantages in specific scenarios. They are beneficial when site constraints like irregular rooftops or shading are present.

In the United States, the best direction for solar panels to face is south as it exposes them to the most sun and allows them to produce the most electricity possible. . East-West Orientations Offer Strategic Value: While producing 75-85% of south-facing output, east and west-facing panels can provide superior financial returns by aligning with time-of-use electricity rates and matching typical household consumption patterns. This conventional wisdom has prevented many families from considering solar simply because their roof doesn't face "the right direction. Arrays that are appropriately oriented can improve energy output by up to 30% or more 2. However, factors such as roof slope and proximity to the equator may have some homeowners considering other directions (including north).
