Is the Investment in Adjustable Mounts Justified by Increased Output?

Importance of Solar Panel Orientation

Solar panel orientation plays a significant role in determining the overall efficiency and output of a solar panel system. The amount of sunlight that hits the panels can vary greatly depending on the direction they face, with ideal orientations receiving up to 30% more sunlight than less optimal orientations. By adjusting the angle of the panels, you can maximize the amount of sunlight they receive throughout the year.

Calculating Potential Gains

Let’s consider a scenario where a homeowner installs a 5 kW solar panel system on a fixed mount, facing south at a 30-degree angle. According to the National Renewable Energy Laboratory (NREL), this orientation receives an average of 5.5 peak sun hours (PSH) per day in a region with moderate sunlight. By adjusting the mount to track the sun, the same system can potentially receive up to 6.5 PSH per day, resulting in an increase of 18% in energy production. This translates to an additional 840 kWh of electricity per year, assuming an average system efficiency of 15%.

Adjusting for Local Conditions

However, the potential gains from adjustable mounts will vary depending on the local climate and geographical conditions. Factors such as shading, wind, and snow load can impact the effectiveness of adjustable mounts and affect the overall return on investment. Homeowners should carefully assess these conditions before deciding on an adjustable mount system, and consider the added cost and complexity of the system when evaluating the potential gains.
