No matter where or how you plan to mount your solar panels there are certain considerations that greatly affect the efficiency, structure, and lifetime of the panels. If selection of mounting frames and placement isn’t investigated carefully before set-up, you could lose efficiency, and shorten the life of your new solar system.

Where to Mount

Solar panels are typically mounted in one of three locations, the roof, the ground, or on a pole. The most common is a roof mount. Roof mounts can be difficult if the roof orientation and angle is not optimum with the solar modules tilt angle. When using a roof mount be sure to allow a clear airflow path up the roof under the solar module. The modules operates cooler and produces more energy if it stands off the roof at least three inches. Keep in mind, that mounting solar panels on the roof does require penetration, so make sure the area is sealed to prevent any leakage problems.

If shading or roof space is an issue, the ground is the next best choice. Mounting frames can set on concrete footings for a ground system.

Using the pole mount for your solar array is the least used option.

No matter where you mount your solar panels, you may want to use a tracker. A tracker “tracks” the sun’s path. Your panels will get the most sun possible during the day as the tracker automatically points your solar array to a perpendicular line with the sun.

Types of Solar Panel Mounting Frames

Several manufacturers make mounting structures that work with almost any solar panel model. Hardware is intended for multiple applications and a variety of mounting techniques. You can have your solar panel mounting structures customized. This customization can be expensive. The mounting material you choose should meet all requirements of your specific region.

Aluminum is lightweight, strong, and resistant to corrosion. Easy to work with aluminum angle is compatible with many PV modules frames. One note, aluminum is not easy to weld.

Angles iron is easy to work but corrodes quickly. Galvanizing slows the corrosion, but the brackets and bolts will rust especially in a wet environment.

Stainless Steel is expensive and difficult to work. Advantages are it will last for decades. In slat spray environments, this can be a very good investment.

Wood- While wood is inexpensive and easy to work, its durability is lacking. Even if treated with preservatives wood may not withstands the weather for many year.

Mounting your solar panels correctly plays an important role in maximizing production and protecting your investment. Make sure to get the proper settings before you mount your panels.
