House Orientation For Solar Panels

This is because the sun is always in the southern half of the sky in the northern hemisphere.

House orientation for solar panels.

However what utilities really want are west facing panels to hit peak. The angle or tilt of a solar panel is also an important consideration. You can also improve your solar panels performance by adjusting the tilt of your panels downward. Even with this decrease in performance solar panels will produce enough electricity to save you hundreds of dollars a year.

Now a compass tells you magnetic north and south but it does not show you true north and south. The angle that a solar panel should be set. Still an exceptional orientation if the majority of your energy consumption occurs between 10 am and 2 pm daily. The direction solar panels should face is true south a k a.

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. Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch. In texas the current structure of compensating for the energy produced by solar panels incentivizes south facing panels. True south can also be calculated at noon when shadows from vertical objects run north south.

However solar panels can be orientated on any roof that faces south of either east or west. If you are looking to achieve cost savings by installing your own solar power system it is highly recommended that you put some time aside and carefully analyze and determine the the right location for your solar panels. Fixed tilt solar. Therefore directions like southwest or southeast are fine.

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. Solar panels should face south for any home in america to obtain maximum power generation. However if your situation is working between 9 am 5 pm an east and west facing solar panel orientation may save you more money while producing slightly less energy as a whole. In the northern hemisphere the general rule for solar panel placement is solar panels should face true.

To correct the compass reading your solar installer will calculate the magnetic declination of your site. Solar south or geographic south. Orientation of the panels. Face the long front side of the home within 20 degrees either side of true south.

The optimum place to install solar panels usually depends on the position inclination and its orientation towards the sun. There is a difference. 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. If you change the tilt from 30 degrees to 15 degrees your production then will be only 15 percent lower than if your.
