Positioning Solar Panels to Maximize Energy Production

Experienced photovoltaic contractors design solar panel systems for optimal performance. To accomplish this goal, a number of factors are taken into consideration.

Rooftop orientation, tilt and shading are of particular concern, as all three can have a significant effect on energy production. Here’s a look at how the Nationwide Solar team positions solar panels to capture the maximum amount of sunlight.

Orientation

Due south is the ideal orientation for solar panel systems in the Intermountain West, but not every home has a south-facing roof.

The solution here? According to the Department of Energy, a rooftop solar array can face up to 45 degrees away from due south without causing a noticeable drop in power output. Therefore, orientation isn’t always a problem – but when a roof faces north or the usable space points too far east or west, photovoltaic panels can be installed on a carport or outbuilding.

Tilt

Solar panels are typically mounted flat against the surface of a rooftop, but homes don’t always have roofing that is angled to capture the maximum amount of sunlight.

The solution here? Research has shown that the optimal tilt angle for a rooftop solar array is roughly equal to the latitude of the location. If a roof is pitched at an angle that’s less than the local latitude, professional contractors use special mounting brackets to properly tilt the photovoltaic panels so that they are positioned for optimal energy production.

Shading

Shade falling on solar panels can cause a drop in power output, and the impact can be immense when shade coves a rooftop array during peak sunlight hours.

The solution here? To understand the effects of shading at a specific location, experienced photovoltaic contractors use specialized tools and software to conduct a thorough analysis. The paths the sun travels during the course of the day and in different seasons are taken into account, and this information helps determine the best spot for a solar array.
