Best Position For Solar Panels On Roof

However solar trackers can be used on a ground installation or on a flat roof.

Best position for solar panels on roof.

While the sun is in a higher position in the sky during the summer and lower position during the winter it has an average position right in between the two seasons. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light. This gives us an accurate output from which we calculate the cost and savings you will get based on your local solar prices and the amount you pay your utility company for electricity.

This being the case the general best practice to date has always been to position solar panels facing south in order to capture the maximum amount of sunlight overall. But in the far north the difference is not so great and in townsville south facing solar panels will only produce around 17 less electricity in total than north facing ones. In sydney south facing solar panels will typically produce around 28 less energy than north facing panels and the steeper the roof the less electricity they will produce.

In fact all southern hemisphere locations should ideally position panels in a northerly direction. Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun. Are vital inputs in order to accurately calculate the solar power potential for a property. They cannot be mounted on a slanted roof.

If your property is located in the northern hemisphere panels facing south will perform best.
