Annual Solar Insolation (tilt angles for solar panels) for Los Angeles, CA

Los Angeles annual Insolation

This is a chart of annual Insolation (solar energy) for the city of Los Angeles. It shows the optimum angle and azimuth for receiving power from the sun. This can be used for finding the optimum tilt and azimuth angles for a solar power array. What this means is – if your roof is angled at about 30 degrees facing due south or south by southwest you will be able to receive the maximum amount of solar energy available. So if you have a roof like this and you want to go solar DO IT!
