which roof direction is best for solar panels

When deciding which roof direction is best for solar panels, south-facing roofs are typically the most efficient in the Northern Hemisphere. This orientation maximizes sun exposure throughout the day, leading to higher energy production. South-facing panels receive direct sunlight for the longest duration, which is ideal for optimizing solar energy output.

East and west-facing roofs can also work but may produce slightly less energy. East-facing panels capture morning sunlight, while west-facing ones benefit from afternoon sun. North-facing roofs are the least effective, as they receive minimal direct sunlight. The best choice depends on your location, roof angle, and energy needs.
