TIPS N TRICKS

Basic panel alignment

Panel angle

Following the colored map you can trim your panels angle accordingly. For a latitude up to 25° take your latitude and multiply it by 0,87 For a latitude between 25° to 50° take your latitude multiply by 0,87 after that you will add 3,1 degrees For a latitude over 50° the most ideal angle will end up being approximately 45° degrees

Panel direction

In the northern hemisphere, the general rule for solar panel placement is, solar panels should face true south and in the southern, true north. Usually this is the best direction because solar panels will receive direct light throughout the day.
