Best House Orientation For Solar Panels

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.

Best house orientation for solar panels.

For the best results solar panels should be oriented towards the south. If your property is located in the northern hemisphere panels facing south will perform best. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. Latitude 2 5 degrees.

However solar panels can be orientated on any roof that faces south of either east or west. Therefore directions like southwest or southeast are fine. Panels that face north will produce the most electricity overall. This is because the sun is always in the southern half of the sky in the northern hemisphere.

What happens if your roof isn t facing south. Face the long front side of the home within 20 degrees either side of true south. When the solar panel orientation is designed specifically to meet your major consumption habits within sunlight hours. The direction solar panels face along with their angle or tilt at that orientation.

Even with this decrease in performance solar panels will produce enough electricity to save you hundreds of dollars a year. North facing solar panels are often the best choice for people who are at home during the day. Are vital inputs in order to accurately calculate the solar power potential for a property. Your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce.

If you ignore the possibility of a solar tracker in the past it was considered a solar panel orientation on an aspect angled toward the equator was the best location for a solar energy system. As we re in the northern hemisphere the best solar panel orientation is obviously south but. Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season. This positions south facing windows to act as solar collectors that bring heat into the house in winter.

Latitude x 0 9 29 degrees. Orientation of the panels. Why orientation matters with rooftop solar in general solar panels that are oriented directly east or directly west will produce about 20 percent less electricity than if they were facing south. The answers you end up with are the best angles for each particular season.
