Which Way To Point Solar Panels

This means that your solar panels will be put in a unique direction specifically to maximize energy production between this time range.

Which way to point solar panels.

When you point your solar panels west you are not maximizing the total amount of energy that is produced. True south can also be calculated at noon when shadows from vertical objects run north south. However there is a difference between magnetic south and true south that must be considered. The pecan street research institute released results of a study that indicated homeowners could find significant benefits by pointing their solar panels to the west.

If your roof does not face the right direction then surface mounted panels or pole mounted panels may be your best bet. To do this you should point your solar panel west. It is at this location that your panels will receive the maximum sunlight throughout the day. There is a difference.

For the best results solar panels should be oriented towards the south. This angle varies and is just about equal to the latitude of your home how far north you are in relation to the equator. To correct the compass reading your solar installer will calculate the magnetic declination of your site. While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.

This is because the sun is always in the southern half of the sky in the northern hemisphere. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. The rule is that if you live in the southern hemisphere you should point your panels true north and if you live in the northern hemisphere you should point them true south. Usually this is the best direction because solar panels will receive direct light throughout the day.

The direction solar panels should face is true south a k a. But a new study based on homes in austin texas has raised questions about which way our solar panels need to be facing. The pull or magnetic declination will vary in direction and strength depending on your location. The study concluded that the west facing panels were better at reducing peak loads in areas such as austin where air conditioning use is a strong driving factor in energy use during peak times typically 3 p.

The most optimum direction to face your solar panels is somewhere between south and west. Solar south or geographic south.
