Most homeowners should choose the Year-Round angle. Choose Winter only if you are off-grid and need to maximize charging during short days. Being 5-10 degrees "flatter" than perfect is often better for self-cleaning (rain washing) than being too steep. Solar. . Tilting your solar panels at different angles can have a big impact on energy output and therefore financial return. But just how big an effect is this? Does it drastically. . Tilt angle is defined as the number of degrees your array orients from the ground so it can face the sun. The 30-degree rule is flexible: While 30 degrees is often cited as optimal, any roof pitch between 15-45 degrees will deliver excellent solar performance, typically within 5-10% of peak efficiency.
